A 10 x 20 print needs a 10 x 20 frame when displayed without a mat, but a matted print requires a larger frame matched to the mat’s outer dimensions.
One extra layer of paperboard is what throws most people off. The print measures ten by twenty inches, the frame opening measures ten by twenty inches, and the two line up perfectly — until a mat slips between them and the whole calculation shifts.
Sizes like 11 x 14 and 16 x 20 sit on store shelves everywhere, but 10 x 20 is a panoramic format you usually have to order. The sections below give you the exact numbers for both setups so you can buy once.
Does A 10 x 20 Frame Fit A 10 x 20 Picture?
Yes, a 10 x 20 frame holds a 10 x 20 print directly when no mat is involved. That is what the size label on the box means.
Retail listings treat a “10 x 20 frame” as the image opening, so the artwork fills the visible window edge to edge. The frame’s outside dimensions are larger, and how much larger depends on the moulding width. ArtToFrame’s 10 x 20 frames spell out a standard image size held of 10 x 20 inches, which is the number that matters when you are checking fit.
One real example shows the gap: a framed 10 x 20 product carries an actual outside size of 12 x 22 inches with 1.25-inch molding. So the frame that holds your print adds roughly two inches in each direction on the wall.
How Do You Size A Frame For A Matted 10 x 20 Print?
A matted 10 x 20 needs a frame cut to the mat’s outer edge, not the artwork’s edge — and that outer edge is always bigger than 10 x 20.
Here is the mechanics. The mat has a window in the middle sized to the print, plus border width all around. The frame’s rabbet, the recessed inner lip that the mat and backing rest against, has to match the mat’s total outer measurement. A 3-inch border on every side pushes a 10 x 20 print into a 16 x 26 frame. Wider borders can push it to 20 x 30.
| Setup | Frame Size Needed | Typical Outside Size |
|---|---|---|
| No mat, full bleed | 10 x 20 | About 12 x 22 with 1.25-inch molding |
| Matted to 8 x 18 opening | Roughly 12.5 x 22.5 | Matches the mat’s outer dimensions |
| Mat with 3-inch borders | 16 x 26 | Frame plus molding width |
| Mat with wide borders | 20 x 30 | Depends on border design |
The safest route: buy the mat first, measure its outside edges, then order the frame to that number. FrameDestination’s picture frame size guide walks through the same measuring order and notes that mat border width is the variable most buyers overlook.
Once you have your measurement, a tested set of 10 x 20 frame options takes the guesswork out of matching moulding styles to panoramic prints.
Why Is 10 x 20 Harder To Shop For?
10 x 20 is a panoramic size, not one of the common off-the-shelf standards. FrameUSA’s standard size list covers 8 x 10, 11 x 14, 16 x 20, 18 x 24, and 24 x 36 — 10 x 20 is not on it.
That means big-box aisles rarely carry it, and the frames you do find tend to be made to order. The upside is real choice in molding and mat color. The trade-off is a wait and a price closer to custom than to a $12 ready-made.
Two fit details bite people after delivery. First, the frame’s rabbet depth — a thick mat plus a thick poster can exceed it, and the backing will not seat. Second, the opening itself: some frames list the held image size, others list the glass size, and the two can differ by a fraction of an inch. Check the “image size held” line before you buy, not after.
FAQs
Can I put a 10 x 20 print in an 11 x 14 frame?
No. An 11 x 14 opening is narrower than 20 inches on the long side, so a 10 x 20 print will not fit without trimming the artwork. Trimming a panoramic print usually ruins the composition. Order a frame built for a 10 x 20 opening instead, or use a larger frame with a custom mat.
Does a mat always make the frame bigger?
Yes, always. A mat adds border material between the print edge and the frame edge, so the frame must be larger than the artwork by at least twice the border width in each direction. If you want to skip that math entirely, choose a 10 x 20 frame and display the print full bleed with no mat.
How do I measure for a matted frame?
Measure the mat’s outside edges, not the print. Lay the mat flat, run a tape along the full width and full height, and order a frame matching those two numbers. Also check that the frame’s rabbet depth clears the combined thickness of the mat, the print, and the backing board.
