An 18×24 frame with a mat is the cheapest way to make a print look like it belongs in a gallery — the mat is what does the work, adding that wide white border that stops a poster from looking like a cheap print. Thin plastic bows, cheap glass clouds over, and a soft backing lets the whole thing warp on the wall. This guide sorts out which ones hold their shape and which ones you will end up replacing.

Our Picks at a Glance
How To Choose The Best 18X24 Frame With a Mat
An 18×24 frame is big enough that the material shows. On a small desk frame you can get away with thin wood and a plastic cover. At two feet across, a flimsy border visibly bows, and a cloudy cover eats the detail in your print. Here is what actually decides whether a frame looks right on your wall.
The mat opening — why it is smaller than your print
A mat is the stiff board inside the frame with a smaller window cut into it. That window is usually cut a little smaller than the photo it holds, often by about half an inch. That is deliberate — the overlap grips the print so it cannot slide down behind the glass. If you order a 16×20 mat and your print measures 16×20 exactly, expect the visible image area to be slightly smaller. That is normal, not a defect.
Glass or plexiglass — the weight and safety trade
Tempered glass gives the clearest view and the most substantial feel, but a frame this big with real glass in it is genuinely heavy, and shipping damage happens. Plexiglass and plastic covers are lighter and shatter-resistant, which matters in a kids’ room or a dorm. Some frames here use glass, some use plexiglass, and a few give you the choice in the description. Neither is wrong — it is a weight and safety call.
Matted or full-border — you can usually have both
Nearly every frame on this list holds a 16×20 print with the mat in, or an 18×24 print with the mat pulled out. That means one frame covers two print sizes. If you already have a 16×20, check the mat opening size in the listing before you buy. If you plan to swap prints around, a frame with a removable mat and easy-open clips saves you a fight with metal tabs.

In‑Depth Reviews
1. Homeforia 18×24 Mortise&Tenon Natural Oak Poster Frame, 16×20 Mat, Glass
Our pick — over 4.5★ from 500+ verified ratings; the strongest balance of quality and price.
The joinery is the tell — corner joints cut to interlock, not just glued and pinned.
Mortise and tenon joinery is an old woodworking method where one piece of wood is cut with a slot and the other with a matching tongue, so the two lock together instead of relying on glue or staples. That is what makes this frame feel like furniture rather than packaging. It is solid oak, fronted by tempered glass — glass that has been heat-treated so it breaks into small dull pieces instead of long shards, which matters on a two-foot-wide frame hanging at head height.
The dual-size setup covers a 16×20 print behind the white mat, or a full 18×24 when you pull the mat out. The mat itself is white, so it reads clean against oak. Hanging hardware and a wall kit are both in the box, which means you are not making a second trip for hooks. What wins people over is the build quality, and it is the thing buyers talk about most by a wide margin — the solid feel and the joined corners come up again and again, with “Buyers repeatedly praise the solid oak and the tight mortise-and-tenon corners.” being a line that sums up the whole review page for this one.
The catch is the price climb and the shipping. This is among the most expensive single frames here, and delivery can run slow — buyers report waiting longer than expected before it turned up, though they also report it arrived beautifully packed and worth the wait. The backing uses a ball-bearing lock instead of standard metal tabs, which is faster to open once you get the hang of it but takes a second to figure out on the first try. It also only comes as a single frame, so a five-frame gallery wall would run you five of these. It carries 4.9 stars across 500+ ratings, the highest score on this list.
What earns this the top spot
- Mortise and tenon corners on solid oak — no glue-only joints or particle board hiding under a veneer
- Tempered glass front for clear viewing and safer breakage if the frame ever goes down
- Ships with mat, tempered glass, and a wall hanging kit all in one box
- Displays a 16×20 print matted or a full 18×24 without the mat
Where it asks patience
- Delivery runs slow — expect a longer wait than most frames here
- Single frame only, so a gallery wall multiplies the cost fast
- The ball-bearing backing lock has a learning curve compared with plain tabs
Reach for this one if: you want the frame itself to be the thing people notice, and you are framing one print you actually care about.
Look elsewhere if: you need five frames for a blank wall — going single-frame here gets expensive quickly, and the multi-pack options lower down do that job instead.
2. 18×24 Picture Frame Matted to 16×20 Photo, Natural Wooden Frame 18 x 24 Picture Frame for Wall, Minimalist Post Frame18 by 24 with Real Glass 18″x24″Art Frame for Home Decor Gifts
Set it on a desk or hang it on a wall — this one does both without extra parts.
This is the TKYGU frame, and its trick is flexibility at a modest outlay. The body is engineered wood, which is a mix of wood fibre and resin pressed into a stable board — it will not warp the way cheap thin timber can, and it keeps the weight down on a large frame. The front is real glass rather than a plastic cover, which on a natural woodgrain finish is exactly what you want for clarity. It comes in a Natural Woodgrain finish with a semi-gloss sheen.
The mat setup is the draw here: mat in for a 16×20 print, mat out for a full 18×24. The listing is upfront that the window is cut about half an inch smaller than the photo on purpose, so the print is gripped and cannot slip down. That matters because behind the glass, a loose print that slides is the most annoying thing about any large frame. It swaps between landscape and vertical, and you can hang it or stand it on a surface.
The honest caveat is sturdiness. Owners are split on how solid it feels once mounted, with some finding it steady and others reporting it coming apart, so treat the frame gently during setup and do not over-tighten anything. Quality and appearance are what get talked about most on the review page, and there is real warmth in the remarks about how it looks — “Reviewers call it better-looking than the price suggests and exactly what they needed.” captures the tone. At 4.5 stars across 600+ ratings, it is a low-risk way to get a woodgrain 18×24 with real glass on your wall. Note also that the listed dimensions here run 18 inches long by 24 wide, opposite the Homeforia’s 24 long by 18 wide listing — same physical frame size, different cataloguing, so measure your wall spot rather than the spec sheet.
What it gets right: real glass over a woodgrain finish, a mat you can pull out, and both wall-hang and surface-stand positioning in one frame — a lot of display options for the entry tier.
What to handle carefully: the pressboard build divides opinion on how sturdy it feels, so mount it once, mount it right, and skip rough handling.
Sensible buy for: a first large frame, a rental wall, or a print you want matted now and full-bleed later.
Not the one for: anyone who wants heft and thickness in hand — the solid wood picks above and below give you more physical substance.
3. Golden State Art 18×24 Picture Frame – Matted for 16×20 Photo Black
A heavy black gallery frame that makes an inexpensive print read as professionally handled.
If your goal is one frame that makes a print look like it came out of a framing shop, this is the cleanest path. It is solid wood in polished black, with real glass and a mat opening measured at 15.5×19.5 inches for a 16×20 print. At 3.49 kg it feels heavy in hand, and the included hangers mount it horizontally or vertically.
The glass does real work on a frame this size: it keeps dust, moisture, and scratches off your photo over the long haul, which is the whole point of putting something behind glass instead of clipping it to a wall. Quality takes the lion’s share of the praise on this listing, with value close behind — “Buyers call it worth the money, substantial in hand, and gallery-ready with the included mat board.” is the sentiment that carries through. Assembly runs about five minutes with tool-free backer glides, so you are not hunting for a screwdriver.
Two things to know. First, this is a matted frame — it is built to show a 16×20 photo behind the mat, and the 18×24 full display is not the intended path here the way it is on others in this list. Second, the mitred corners are fine but not the tightest cut you will see at a higher tier, one owner’s print colors read slightly less vivid on arrival than the product photos suggested, and there is no hanging wire included — you use the back hangers. At 4.6 stars across 800+ ratings, it is a very good retail frame rather than a custom-shop build. What it does not give you is mat color choice, which a few buyers wish existed.
The core case: solid wood, real glass, a heavy backer, and a mat opening cut for 16×20 — it presents a print the way a frame shop would, without the frame-shop process.
Worth knowing: the mat is sized for 16×20 only, not a full 18×24 swap, so buy this one when your print size is already settled.
Right call when: your print is a 16×20 and you want it to look expensively handled on a black gallery wall.
Think twice when: you want the option to run a full 18×24 borderless later — other frames here switch sizes, this one is built around its mat.
4. upsimples 18×24 Picture Frame, Gallery Wall Frames Set of 5, Black
Five 18×24 frames in one box — the fastest route to a wall that looks finished.
Buying frames one at a time is how gallery walls stall halfway. This is a set of five identical black frames, each sized to hold a 16×20 print behind the mat or a full 18×24 without it, so you can build the whole layout in a single order without hunting for matching sizes. The frames are plastic with a plastic cover rather than glass, which is the reason the price for five stays reasonable — and it is also why you can hang these without worrying about a heavy frame coming off the wall.
The lightweight construction is not a compromise here, it is the point. What the review page keeps coming back to is how light they are — light enough that a simple hook holds one up, light enough to hang a row of them alone without a second set of hands. Beyond that, value and looks get the most attention, and the remarkable thing is how high-end they read in person given the build; you would not guess plastic looking at the wall from across a room.
Two caveats. First, the front is plastic, not glass, and it scratches more easily than glass does — you want to be careful when cleaning or moving the frames. Second, plastic-on-thin-wood construction only goes so far: owners describe it as simple and clean rather than grand, which is exactly what you would expect at this tier. For filling a wall in a dorm or a first apartment, five matched frames at this level of finish is the practical play.
Why the five-pack makes sense
- Five identical frames solves the whole gallery wall in one purchase
- Light enough to hang on basic hooks without extra wall support
- Each frame handles a 16×20 matted or a full 18×24 print
- The lightweight build means a simpler, safer hang than heavy glass
What to expect at this build level
- The front is plastic, not glass, and it scratches if you handle it roughly
- Plastic and thin wood construction reads as clean and simple, not substantial
- The mat opening overlaps your print by about half an inch by design
Built for: the empty wall, the dorm room, the apartment that needs three or four matching frames at once.
Not built for: a single statement piece — one heavy solid wood frame has more presence than five plastic ones, and that is a different decorating job entirely.
5. Heimlove 18×24 Picture Frames Natural Teak, Original Wood Hand Make Crafted Poster Frame with Mat to 16×20 Graduation Picture Display, Family Picture, Wedding Picture, Photo, Document Wall Mounted
Real teak with a grain pattern you will not find on a second frame — because it is a tree, not a print.
The wood here is natural teak, and the seller is upfront that the grain pattern comes from how that specific tree grew — meaning the frame you receive has a pattern no other one has. Real teak has a natural oil content and weather resistance that makes it unusual at this price band; it is a wood typically reserved for outdoor furniture and boat decking, and here it is doing duty on a wall frame. The finish is a satin sheen with a matte feel, and the cover is real 2mm tempered glass — 2mm is the thin side of tempered glass at this size, so you get clear views with less weight than heavier glass options would give you.
The frame handles a full 18×24 display, or a 16×20 with the mat, and it mounts at two heights — wall hanging or on a tabletop. It comes in a Country Rustic style, and the handmade construction runs from designing to cutting to polishing to a waterproof paint finish, so every piece has that slight individual character you get from a hand-built frame. Buyers come back to how the frame feels in hand as much as how it looks on the wall; this frame earns its keep on how solid and well-made it feels rather than any single standout detail.
The honest caveat is the color. Because the finish is natural teak and every piece of wood is different, the tone you get in the box can read warmer or cooler than the product photos suggest, and buyers are split on this — some love it, some find it off from what they expected. If you are matching a frame to an existing wood floor or furniture finish, this is the risk to think about. If you are buying this as the one dominant piece on a wall and you like natural wood texture, the variation is the charm rather than the problem. One owner was blunt that the color simply landed differently than they pictured.
The strongest ground: handcrafted teak, 2mm tempered glass, and a mat that supports 16×20 with a full 18×24 fallback — a genuinely individual frame at a reasonable tier.
The honest catch: natural wood means natural variation, and the color that shows up may read a shade different from the listing photos.
Pick it when: you want a warm wood tone with real character and you appreciate that no two frames match exactly.
Skip it when: the frame needs to match a specific existing wood finish down to the shade — the natural variation makes that a gamble.
6. Venusmiles 18×24 inch Picture Frame, 18×24 Photo Frames with 16×20 Removable Mat – High Definition Plexiglass – Vertical and Horizontal Display – Wall Hanging Poster Frame – Gold, 3 Pack
Three gold 18×24 frames with a made-for-kids-room build — no glass to break.
The trim here is a matte gold that reads as a deliberate accent rather than a neutral. It is a plastic frame with a polycarbonate front, and the polycarbonate is worth explaining: it is the same family of material used for safety eyewear, engineered to resist shattering on impact. That is precisely why this pack lands in kids’ rooms and dorm rooms — if a frame ends up getting knocked off the wall, the front panel will not create the kind of hazard a pane of glass would. The mat opening measures 15.5×19.5 inches for a 16×20 print, and you pull the mat out for a full 18×24.
What buyers come back to is the value of the three-pack for the money — you get three matched frames for roughly what a single high-end one costs, and users on the review page consistently mention how stable the finish and assembly turned out for the price. The corners are hand-polished, and the backplane is moisture-proof, protecting the print from humid rooms. If you peel the protective film from both sides of the polycarbonate before mounting, the front goes from dull and hazy to clear, which is the most common assembly note.
The trade-offs are minor but real. The frame border is thin, so it feels lightweight in a way some buyers like and some do not — this is a living space frame, not a piece with the weight and presence of the solid wood options higher on this list. The gold is a yellow gold, warmer and more saturated than some shoppers may picture. Assembly uses the standard back tabs plus a pull tool included in the box, so if you have mounted a poster frame before, this setup will feel familiar. One reviewer noted there were no mats included on their variant — the listing states a mat is included with this model, so check your selected option before ordering if the mat is important to you.
Where the three-pack earns its keep
- Three matched frames at the price of roughly one premium single frame
- Polycarbonate front is shatter-resistant — no glass shards if it falls
- Mat opening sized for 16×20, or full 18×24 with the mat pulled out
- Moisture-proof backplane helps in humid rooms and bathrooms
Limits worth knowing
- Thin frame border gives a lightweight feel next to solid wood options
- The gold leans yellow — warmer than a soft muted gold
- Confirm the mat is included with your specific variant before ordering
A good fit for: a nursery, a kids’ room, or a dorm where you want three matched frames on a wall, on a tight budget, with shatter resistance in mind.
Better choose elsewhere if: you want a substantial frame border that feels anchored on the wall — this one is airy and light, and the solid wood picks serve that need instead.
7. FLYJOE 18 x 24 Poster Frame | Solid Oak Wood 24×18 Poster Frame | 18 x 24 Picture Frame With Mat For 16×20 | Tempered Glass And Hanging Hardware Included | Puzzle Frame 18×24 Wood (Walnut, 1 Pack)
A solid oak frame with rounded corners and a built-in easel for shelf display.
The frame material here is FSC-certified solid oak — FSC certification means the wood is tracked back to a responsibly managed forest, so you know the source rather than just taking the seller’s word. It is finished in a Walnut tone with a textured surface, and the corners are rounded rather than squared — a detail that keeps the frame from looking severe on traditional or farmhouse walls. The front is 2.0mm tempered glass, with polished edges so handling it during a swap does not risk a cut.
The real differentiator is the mounting range. You can hang it on a wall horizontally or vertically, but it also has a built-in easel so it stands on a desk, shelf, or mantel. That easel is the reason this frame earns a spot even if you already have wall artwork handled — it lets the same 18×24 frame work as a leaning shelf piece, which most frames in this list cannot do because they are wall-only. The mat gives you a 16×20 display, and removing it opens up the full 18×24. It ships with hanging hardware and easy-clip fasteners so a swap is quick.
Two honest notes. First, the backing is Medium Density Fiberboard — good for stability, but it is not solid wood through and through the way the frame border is. Second, one buyer mentioned cracked or scratched plexiglass on arrival, so if your frame does show up with damage, return it rather than trying to work around it; that is a shipping issue, not a build quality issue. What gets buyers positive about this one is the rounded edges and the overall look — the frame reads more expensive in person than the listing photos suggest. The mat edge sits at a half-inch inset like most on this list, which is standard.
Where it stands out: the built-in easel is unusual for an 18×24 frame — most of these are wall-only, so this one covers both a desk display and a wall hang with the same piece.
One risk to check: with tempered glass at this size, shipping damage does happen — inspect the frame the moment it arrives and return immediately rather than working around a crack.
Suits you if: the frame may move between a shelf and a wall over time, or you want the option to lean it rather than commit to a permanent hang.
skip it if: the plan is a fixed wall install and you prefer a frame with the full heftiest wood backer — the FLYJOE casing is solid oak, but its backer is MDF, and a buyer who cares about that cares about it a lot.
8. VCK 18×24 Poster Frame 5 Pack, Brown Wood, 16×20 Mat, for Wall Art
Five brown wood-finish frames with UV-blocking plexiglass — built for a real project, not one print.
Five frames is a different job than one frame. The use case here is running an art show, framing for a local gallery, or working across a large family display — this is the kind of pack that gets bought in volume by people who need matched packaging across many prints, and owners mention using it exactly that way. The frame is FSC-certified engineered wood, so it holds its shape and resists warping and fading better than a plain composite frame would. Each outer frame measures 19.3 x 25.3 inches, which leaves the standard border around an 18×24 or 16×20 print once the mat is in place.
The front here is plexiglass, not glass, and that choice is deliberate: it is thicker and more shatter-resistant than basic plastic sheeting, cuts glare, and blocks UV rays to keep prints from fading — the feature that most matters if you are displaying repeat artwork over a long stretch of time. Mat-in for 16×20, mat-out for full 18×24. The back uses 360-degree metal clips that rotate open without needing tools, so changing prints takes seconds. Quality is the top-talked-about trait across the review page, with value right behind it, and the overall impression is that these look professional rather than economical.
The clear downside to plan for: with five frames in one shipment, corner damage is a real risk, and durability is where the frame at its most vulnerable — one owner in the review set ran into that. The good news is that if you get a rough one, swapping it out for an equally-matched replacement is straightforward because the pack is standardized. The size itself is also slightly mixed in the review notes — a couple of owners noted the mat gave a little more or less print overlap than expected — but the listed fit for both 18×24 and 16×20 is consistent across the product. Note the plexiglass ships with protective film on both faces, so peel both before you judge the clarity.
The value case: five frames with UV-blocking plexiglass and tool-free 360-degree clip backs, at roughly the level of a single solid-frame purchase — this is the option you choose when quantity and consistency matter more than heft.
The practical risk: five frames in one box means one may arrive with a dented corner, but the standardised build makes a replacement easy to swap in without breaking the gallery effect.
Right frame for: artists, teachers, gallery sellers, and anyone hanging a row of matched prints who needs identical frames without hunting piece by piece.
Stay with a single frame instead if: you are framing one print and care most about hand weight and presence — the solid wood single-frame options above are stronger on that specific measure.
9. Frame Amo 18×24 Black Poster Frame, 16×20 and 12×18 Mats, Glass, Solid Wood
Two mats in the box: one cut for a 16×20, one for a 12×18 — one frame, three display sizes.
Most frames here give you one mat. This one gives you two. The first mat cuts the frame down to a 15.5×19.5 window for a 16×20 poster; the second cuts to 11.5×17.5 for a 12×18 poster. Both mats are acid-free, which matters because acidic cardboard or paper mats can discolor a print over time behind glass — this is the same reason museums use acid-free board in custom framing. On top of that, the frame itself fits a strict 18×24 poster with no mat. That means one purchase covers three standard print sizes, which is hard to match elsewhere on this list.
The build is solid wood with a 1.5-inch border and 1-inch thickness, a matte black finish, and tempered glass up front. The outer dimensions are 20.5 x 26.5 inches, so the frame takes up real wall space — measure before you plan the spot. It arrives fully assembled with back hooks pre-installed for portrait or landscape hanging, and the user is meant to hang from those back hooks, not from the frame border. A round of customers note a substantial, heavy feel to the frame itself, and “Owners describe the frame as very strong and the hanging hardware as heavyweight.” is a fair summary of what the review page keeps circling back to.
The trade-off is assembly tolerance. Hanging this frame is described as easy by plenty of buyers but fiddly by some — the frame is heavy and there is real hardware involved, so it is worth having the right anchor and a second opinion on placement before you drill. It also only displays a strict 18×24 without a mat, not the customary 18×24 borderless with a slight crop, so if your poster is even slightly undersized it will need the mat behind it. The size-versus-price math is right for what you get: three display sizes from a single frame plus a solid wood border and tempered glass, above the range of a single-purpose matted frame.
What makes this one different
- Two acid-free mats in the box: 16×20 and 12×18 in addition to full 18×24
- Solid wood border at 1.5 inch wide, 1 inch thick — substantial in hand
- Tempered glass, not plexiglass or plastic, over the front
- Fully assembled with back hooks pre-installed for either hanging orientation
What to watch for
- Large outer footprint at 20.5 x 26.5 inches — confirm wall space before ordering
- Heavy frame and hardware mean a more careful hang than a lightweight wall frame
- The borderless setting expects a strict 18×24; undersized posters need the mat behind them
Reach for this one if: you have prints in more than one standard size and want a single frame that handles all of them — 12×18, 16×20, or a full 18×24.
pass on it if: your wall space is tight or you want a quick clip-and-go wall frame — the weight and hardware here reward a bit of planning.
Understanding the Specs
Mat Opening vs Frame Size
An 18×24 frame and a 16×20 print are often paired together because the mat fills the gap between them — the mat board sits inside the frame and hides the difference between the two sizes. The visible image window is the mat’s inner cutout, not the frame’s outer size. On this list those openings land at roughly 15.5×19.5 inches for a 16×20 mat, and slightly smaller than that for a 12×18 mat. In practice this means the printed image you see will be a little smaller than the paper you loaded, often by half an inch. That is by design: the overlap grips the print and stops it slipping behind the glass.
Glass vs Plexiglass vs Plastic Covers
There are three common front covers on 18×24 frames. Tempered glass is real glass that has been heat-treated so that when it breaks it shatters into small dull chunks rather than long shards — heavier, clearest, and safest glass. Plexiglass is a plastic sheet in the acrylic family that is lightweight and shatter-resistant; the trade-off is that it scratches more easily and can look slightly less crisp than glass at first glance. Polycarbonate is the same family used for safety goggles and is the most impact-resistant of the three. All three protect the print from dust and handling; the choice is really about weight, safety, and how crisp you want the front to look.

Final Thoughts: The Verdict
For most wall projects, the 18×24 frame with a mat winner is the Homeforia 18×24 Mortise&Tenon Oak Frame because the mortise and tenon joinery, tempered glass, and 16×20 mat give you a piece that reads as furniture rather than framing hardware. If you want a full 18×24 frame that handles multiple print sizes from one purchase, grab the Frame Amo 18×24 Black Frame with Two Mats — two acid-free mats plus a solid wood border make it the only one on the list that covers 12×18, 16×20, and 18×24 in the same box. And for filling an entire wall with matched frames in a single order, the five-packs from upsimples and VCK are the ones to reach for. Everything on this list holds either a 16×20 matted print or a full 18×24 poster, so pick based on the print you actually own and the wall you are filling.
