Guide to Frame and Mat Dimensions for Common Print Sizes

Written by Mark Rogers

Art comes in many shapes and sizes. But when we’re talking about photographs and art prints, there are certain popular dimensions of art that make it easier to find a way to display it.

If you’re framing your prints without a mat board, finding a frame is easy. The frame size — the measurement of the inside of the frame — is the same as the print, so a 5 x 7 print will fit in a 5 x 7 frame. Photo and art prints are often matted, however, which adds another dimension to your framing project.

Instead of measuring and figuring out the right dimensions of the frame and the mat board yourself, refer to our list of the most common mat opening and frame sizes based on your print or photograph.

Photography: most common print sizes and frames

Fine art photography and other types of professional art — whether bought at an art fair, gallery show or directly from the artist — are often sold in just a few sizes, and there are customary mat board and frame sizes for all of them.

Note that for prints measuring 18 x 24 inches and under, Frame Destination cuts the mat window 1/8 inch smaller than the print, allowing for more of the image to show through. Standard, off-the-shelf frames and other frame shops may cut the mats 1/4 inch smaller. The suggestions listed below use Frame Destination mat cutting standards.

Photo Print Size Mat Window Opening Picture Frame (Inside)
5 x 7 4 3/4 x 6 3/4 8 x 10, 11 x 14
8 x 10 7-3/4 x 9-3/4 11 x 14, 16 x 20
11 x 14 10 3/4 x 13 3/4 16 x 20
12 x 18 11 3/4 x 17 3/4 16 x 22, 18 x 24, 20 x 26
13 x 19 12 3/4 x 18 3/4 18 x 24
16 x 20 15 3/4 x 19 3/4 20 x 24
17 x 22 16 3/4 x 21 3/4 24 x 28

Art prints: most common print sizes and frames

Because art prints are reproductions of original work, the print sizes (like photography prints) are generally similar. If you’re buying art prints from countries other than the United States, you may encounter unfamiliar sizing like A2, A3, A4 and so on.

These print sizes are part of the A series in the ISO 216 standard, which is used extensively around the world. The measurements are listed below, along with conversion to imperial units and corresponding Frame Destination artwork and frame size.

There are no standard U.S. frame sizes that exactly match these ISO 216 paper sizes, so custom picture frames are the best way to get a perfect fit. However, there are also “close enough” standard sizes that may work with your artwork. Note that some sizes may still be hard to find or too large for the type of art you’re displaying.

Artwork Size Mat Window Opening Picture Frame (Inside)
A2
420 mm x 594 mm
16.5 x 23.4
(16 1/2 x 23 7/16)
16 1/4 x 23 3/16 21 1/2 x 29 7/16
Close Enough: 22 x 30
A3
297 mm x 420 mm

Frames for unique print sizes

When you want to frame artwork with a unique size, order a custom frame to get an exact match for your print. Our website’s custom Build-A-Frame™ allows you to enter your artwork size and, using these dimensions, automatically calculates the recommended mat window opening and frame size. On our site, you can create a frame up to 40 x 60 inches.

If you need help calculating your custom dimensions, there are tools available online that can convert from metric to imperial measurements and vice versa. You can also contact us at 972-479-1188 or at [email protected].

Whether or not you’re working with a common-size photo or art print, we’re here to help make sure the end result is uncommonly beautiful. To find more information about picture frames sizes see our resource page: Guide to Picture Frame Sizes.

    • Laura W

      It really just depends on what you want to see. Our mats are custom cut to any size you'd like, so you'll need to choose a border size and it'll dictate your mat size from there. If you'd like 2" borders, the mat would wind up at 14" x 19", just for example.

    • Laura W

      A3 paper is about 11.69" x 16.53". The closest this comes to is 11-11/16" x 16-17/32" in fractional form for framing. It won't be exact, but this fairly close to the opening for your mat window. How big you want your borders to be will determine the outside size of your mat.

      Hi Bonnie - the inside dimensions are determined by the artwork. Our company will allow you to customize to any inside mat size you'd like. You'll find precut mats for sale at other places that have a 20" x 30" cutout in a 24" x 36" mat, but it can vary depending on the manufacturer.

    • Joely Rogers

      Hi Robin, it really depends on your preferences and wall space. For a poster that size, I'd select a mat border border between 2 - 4 inches. Keep in mind that the larger the mat border, the bigger the materials and greater the cost.

    Reply
    • Laura W

      Hi Tiff - Certainly, you can add a mat board with outside dimensions of 24x36, and a window cut to the art dimensions that you'd like to see (17x22 if you want to view the full piece, or 16 3/4" x 21 3/4" window if you need it to overlap the photo a little bit). You can select a mounting board as well to go behind your photo at 24x36 and you'll actually use that to keep your photo flat and centered. Here's some links to our mat and mounting pages: Frame Destination Mat Page Frame Destination Mounting Board

    I just completed a puzzle and it's a gift. It's 335x480mm. Converted it looks like it's 13.18 x 18.89 inches. For this what size frame and mat would be appropriate.

    Thanks in advance

    Reply
    • Laura W

      Hi Peggy - Converted to the standard system, the closest it seems to be is 13 3/16" x 18 7/8". The outside dimensions of the mat will depend on how large you're wanting your mat borders. You could do a mat with a window that either overlaps the puzzle, or one that just surrounds it without covering any of it. To overlap, you'll want a window of about 13 1/16" x 18 3/4", and then a 1" border would make the outside of the mat (and the inside of the frame) 14 1/16" x 19 3/4". If you just wanted to surround the puzzle and not use an overlap, you could do a window of 13 1/4" x 18 15/16". With a 1" mat border, that would make the outside mat dimension (and inside frame dimension) 14 1/4" x 19 15/16". It's really up to how you'd like to see it.

      Hi Lexi - On our site, it'll ask you for the canvas dimensions and then it will automatically add an inch. So the floating frame dimensions will be 19x25. This allows for a 1/2" float space around the canvas. Of course, you can alter these a little bit if you'd like a smaller or larger space around your print. Our customer service team will also be able to help with the dimensions. They're available via phone (972-479-1188), live chat and email ([email protected]) during normal business hours.

    Hi! I am trying to get a frame or shadow box to put on 2 size canvases - the sizes of the canvases are 11x14 and 7x7. What size frames OR shadow boxes do you suggest I get for each? I am having trouble finding the correct sizing and keep having to do returns! Thanks!

    Reply
    • Laura W

      Hi Marci - You could try a canvas floater frame specifically made for canvases, but it won't have the glazing in front of it. As far as our sizing goes, we size from inside the frame, so you'll want an exact 11"x14" or 7"x7" shadowbox or frame, whichever you're choosing. The most important piece will be the depth. The shadowbox or frame will need to be deep enough for the canvas to sit in, but not so deep that there's a ton of extra space inside of it. Our customer service team can certainly help you out through the process as well. Thanks!

    • Joely Rogers

      Heidi, if you aren't using a mat board, you can order a 25" x 30" frame. We cut the frame so that it's 1/8" inch larger to fit the artwork. Keep in mind that it will overlap the picture by 1/8" inch on all sides. If you do want to use a mat, I suggest you take a look at our https://www.framedestination.com/blog/picture-frames/picture-frame-dimensions-explained if you aren't familiar with mat boards. The website can calculate a custom mat board size. You can also either email [email protected] or call our office at 972-479-1188 for guidance on mat selection.

    Hello. I was gifted a torn paper collage, landscape orientation. Width is 20" with a half inch white border on the bottom and sides. Height is 19" and the image runs to the top edge with no border. I do not know whether to get a 20 x20 frame no mat, or 20x24 with mat-- although the mat would be too small also. Could I float the artwork in 20x24 under glass? I know it's a complicated size and I appreciate your assistance.

      Hi Laura, yes, that's a tough one because the image goes all the way to edge at the top. You could crop a bit off the top; however, I'm familiar with collage work and there's usually not much, if any, dead space to crop. I would either mount it on acid free foam with no mat or float it on a piece of uncut acid free mat board. Hope that helps!

    I just purchased an A4 and I’m clueless as to how to frame it with a mat border. I would actually like a 3 to 4 inch border. I did notice that the inside border sizes were smaller than the print itself unless I misunderstood the graph. What size would you suggest and how do I go about ordering the right size border? This is all very confusing.

    Reply
    • Joely Rogers

      Lisa, most prints come with a white border around the image. The easiest way to mat it is by cropping the image a small amount, typically 1/8" on all four sides. The term for this is "Overlap", which refers to how much of the artwork will be covered by the mat board. A standard mat window opening overlaps anywhere from 1/8" – 1/4" of the artwork. If you want to do that, then measure the image (not the overall print).
      Our website has a "Customize" feature on the frame ordering page where you can put in your image size and choose how much you want it cropped. You can then choose the size of your mat border. It might be easier for you to call our customer service office at 972-479-1188. They are open Monday - Friday, 9AM - 5PM Central Standard Time and can walk you through the order.

    • Laura W

      Hi Caroline - You can customize any of our frames to the size you're needing for this. As far as a mat goes, it really just depends on how you'd like it to look. With something this large, I'd stick to 2-3" borders. If you went with 2" borders all the way around, the outside mat dimensions, and inside frame dimensions would be 28" x 30".

    I wanted to frame photos that I had cropped into a 16 x 9 format.
    Maybe print them as big as 32 x 18 inches or to suit a frame size (but hopefully large:)

    I wanted a mat border around that photo and then the frame of course:)
    2 questions please:

    What size frame do you recommend and stock?
    Do you ship to Australia?

    I have a set of prints measuring 31 1/2" x 21 3/4". I believe I want to double mat these prints, what size frame do I need for print, double matt, acrylic, and foam board backing? The mat would be 1/2 bordering print on top and sides, but probably needing a cut out on bottom for print title....

    I have a puzzle that I would like to frame. The puzzle has a "trim" (part of the puzzle) that I do not want visible. The overall size of the puzzle is 15" x 20 7/8", the part that I want to show is 12" x 18 7/8". Would you recommend a custom mat or trimming the puzzle. Thanks

      Good afternoon Timothy!
      The size of your frame will actually vary depending on your border sizes. You can choose any of our frames, then go to customize frame and it will take you through your framing content options.
      Here you can put in your artwork size, choose your mat border size and the other contents of the frame.

      Have a great day and give a call if you have any questions.

    What size should I get my daughters senior picture in and should I use a matt when I frame it or is that not appropriate. I honestly don’t know. Also I’d like it to be bigger then n 8x10 or 11x14 but I’m worried about how big to go. I have to daughters n will be getting both at the same time so they will be hung side by side or near each other. Any suggestions or professional opinions would be greatly appreciated
