A 13×16, 14×16, or 16×16 frame label describes the size of the picture opening, so it fits a print of exactly those inch dimensions.
The number on the frame sticker almost never describes the frame itself — it describes what goes inside. That misunderstanding is why prints ordered online won’t drop into a frame bought in the same size range: a 14×16 print won’t sit flush in a 13×16 opening, and a square 16×16 canvas hits a 16×20 frame only with a custom mat. Measure the artwork before checkout and you save a return.
What The Numbers On A Frame Actually Measure
Frame labels describe the opening, not the outer molding. A frame listed as 13×16 holds a 13 x 16 inch print exactly; a 14×16 frame is cut for a 14 x 16 inch photo, print, or document; a 16×16 frame takes a 16 x 16 inch square. Outside dimensions run larger — often by an inch or more per side once molding and mat are added.
That gap trips up wall planning too. A tape measure across a filled 16×16 frame reads wider than 16 inches, and that larger number is what matters for spacing a gallery wall.
Frame Destination’s picture frame size guide explains the same principle: the labeled size tracks what the frame is designed to display.
How To Measure Before You Buy
Measure the artwork width and height in inches, then match that number to the frame label. Lay the print flat and run a tape edge to edge both ways. If there’s a printed white border, decide now whether it shows or hides behind a mat — a print with a visible border is often a different size than the artwork area suggests.
Next confirm the framing style. Full-bleed means the image runs to the frame edge with nothing overlapping, so the frame must match the print exactly. A visible border means a mat may do the sizing work instead. A mat opening is cut slightly smaller than the print so the paper can’t fall through, with overlap depending on mat border width.
| Frame Size | Fits This Print | When It Works |
|---|---|---|
| 13×16 | 13 x 16 in | Exact-fit print with no border |
| 14×16 | 14 x 16 in | Photo or document sized 14 x 16 in |
| 16×16 | 16 x 16 in | Square artwork or canvas print |
| 16×20 | 16 x 20 in | Common US size, matted or full-bleed |
| 11×14 | 11 x 14 in | Standard US size, easy to find |
| 8×10 | 8 x 10 in | Standard US size, most common |
| 5×7 | 5 x 7 in | Small desk or shelf frame |
Standard US Sizes Versus These Three
13×16 and 14×16 are specialty sizes in the US, while 4×6, 5×7, 8×10, 11×14, 16×20, and 24×36 dominate store shelves. Big-box stores stock the standards in depth but rarely carry a 13×16 or 14×16; those lean toward custom or specialty online listings with thinner availability. A roundup of tested 13×16 picture frames is worth checking before ordering blind, since fewer options exist and quality varies more.
16×16 sits in an odd spot too: it’s square, so it doesn’t line up with the rectangular 16×20 standard, and matting plus molding thickness can shift the usable inside fit. Frame Destination’s guide to frame and mat dimensions notes that a smaller matted print typically goes into a larger frame rather than a same-size one.
If a standard size won’t work, the fallback is a larger frame plus a custom-cut mat, giving you the exact opening without hunting for an exact-size frame that may not exist. One more check: for thick artwork — a stretched canvas, a board-mounted piece — measure the rabbet depth, the recessed lip holding the contents. Frame profiles vary, and a shallow rabbet can’t swallow a thick piece.
Frequently Asked Questions
Does a 14×16 frame fit a 13×16 print?
Yes, but not tightly. A 13×16 print in a 14×16 frame leaves roughly an inch of visible gap unless you add a mat sized to the smaller print. Without one, the print shifts and shows the backing behind it, so plan on a custom mat when pairing those sizes.
Is a 16×16 frame a standard size?
It counts as a square standard, but it’s less common in stores than 8×10 or 11×14. Square frames in this size usually appear in specialty or online listings, and matting plus frame thickness can change how much of a 16 x 16 inch print actually shows.
Can I use a frame that’s bigger than my print without a mat?
You can, but the print will slide and the gap shows the mount behind it. A mat fills that space and holds the print centered. It’s the standard fix when a frame’s labeled size and your artwork size don’t line up exactly.
Where do I measure on a frame to confirm it fits?
Skip the outside edges and measure the inside opening instead. That’s the number matching the label. Measuring across the front of a filled frame gives the outer molding size, which always runs larger than the labeled print dimension.
