Standard photo size chart
Print sizes in inches (width × height) and centimeters, the shape of each, and the pixels a photo needs to fill it at 300 PPI (pixels per inch, the resolution Shutterfly recommends) and at 150 PPI. "Sold by" lists which of four large US labs sell that exact size.

Mpix sells every size in the chart plus in-between sizes such as 4 × 5.3, and panoramas like 5 × 15 and 10 × 30. Mpix and Walgreens both sell 4 × 5.3, which is close to the 3:4 shape of a phone photo. Canon's photo printers use Japanese size names: L for 3.5 × 5, KG for 4 × 6 and 2L for 5 × 7.
What size is a wallet photo?
Usually 2.5 × 3.5 inches (6.4 × 8.9 cm), the size Mpix, Shutterfly and Nations Photo Lab sell. Walgreens and Lifetouch school photos use a smaller 2 × 3 inches. CVS doesn't list a size; it prints several wallets on one 4 × 6 sheet, which holds four 2 × 3 prints.
| Lab | Wallet size (in) | Notes |
|---|---|---|
| Mpix | 2 1/2 × 3 1/2 | Sold in sets of 4 |
| Shutterfly | 2 1/2 × 3 1/2 | Its only wallet size |
| Nations Photo Lab | 2 1/2 × 3 1/2 | Square corners, sheets of 4, 8 or 16 |
| Nations Photo Lab (die-cut) | 2 5/16 × 3 5/16 | Rounded corners, perforated sheets of 8 |
| Walgreens | 2 × 3 | "2x3 Wallet Photo Prints" |
| Lifetouch (school photos) | 2 × 3 | Packs of eight 2" x 3" wallets |
More on sheets, pixels and which to order: wallet size photo dimensions.
What size is a standard photo?
4 × 6 inches (10.2 × 15.2 cm). All four labs above sell it, and it is the size in the title of CVS's photo prints page. Its 2:3 shape is the same as a 3:2 camera photo turned upright (a Sony α7 IV shoots 7,008 × 4,672), so those print on 4 × 6 with nothing cut off. Full details: 4x6 photo size in inches, cm and pixels. For the 8 × 10 enlargement, see 8x10 photo size.
What resolution do you need to print a photo?
Labs publish different targets. Shutterfly recommends 300 PPI (1,200 × 1,800 pixels for a 4 × 6). Mpix calls 250 PPI optimal and accepts 100 PPI as a minimum. Nations Photo Lab lists 125, 180 and 300 PPI and says images at 125 PPI or more print well. Pixels as each lab lists them:
| Size (in) | Shutterfly recommended | Mpix optimal | Mpix minimum |
|---|---|---|---|
| Wallet | — | 625 × 875 | 250 × 350 |
| 3.5 × 5 | — | 875 × 1,250 | 350 × 500 |
| 4 × 4 | — | 1,000 × 1,000 | 400 × 400 |
| 4 × 6 | 1,200 × 1,800 | 1,000 × 1,500 | 400 × 600 |
| 5 × 7 | 1,500 × 2,100 | 1,250 × 1,750 | 500 × 700 |
| 8 × 8 | — | 2,000 × 2,000 | 800 × 800 |
| 8 × 10 | 2,400 × 3,000 | 2,000 × 2,500 | 800 × 1,000 |
| 8.5 × 11 | — | 2,125 × 2,750 | 850 × 1,100 |
| 8 × 12 | — | 2,000 × 3,000 | 800 × 1,200 |
| 11 × 14 | — | 2,750 × 3,500 | 1,100 × 1,400 |
| 12 × 12 | — | 3,000 × 3,000 | 1,200 × 1,200 |
| 12 × 18 | — | 3,000 × 4,500 | 1,200 × 1,800 |
| 16 × 20 | 4,800 × 6,000 | 4,000 × 5,000 | 1,600 × 2,000 |
| 16 × 24 | — | 4,000 × 6,000 | 1,600 × 2,400 |
| 20 × 24 | — | 5,000 × 6,000 | 2,000 × 2,400 |
| 20 × 30 | 6,000 × 9,000 | 5,000 × 7,500 | 2,000 × 3,000 |
| 24 × 36 | — | 6,000 × 9,000 | 2,400 × 3,600 |
Pixel count is not the whole story: Nations notes that camera settings, zoom, lighting and cropping also affect how a print looks. Mpix says phone photos usually print well if you upload the original file, not a copy sent by text or posted to social media, which is compressed. To turn any pixel count into inches, use the pixels to inches converter.
Photo print sizes by aspect ratio
Prints with the same shape scale up without cropping: a 4 × 6 enlarges to 8 × 12 or 20 × 30, but not to 8 × 10. Sizes in the chart grouped by shape:
| Ratio | Decimal | Sizes (in) |
|---|---|---|
| 1:1 | 1.00 | 4x4, 8x8, 12x12 |
| 5:6 | 1.20 | 20x24 |
| 4:5 | 1.25 | 8x10, 16x20 |
| 11:14 | 1.27 | 11x14 |
| 17:22 | 1.29 | 8.5x11 |
| 3:4 | 1.33 | 18x24 |
| 5:7 | 1.40 | Wallet, 5x7 |
| 7:10 | 1.43 | 3.5x5 |
| 2:3 | 1.50 | 4x6, 8x12, 12x18, 16x24, 20x30, 24x36 |
Cameras shoot in a few fixed shapes. Sony's α7 IV and Fujifilm's X-T5 record their full resolution at 3:2; Micro Four Thirds cameras such as the OM-D E-M10 Mark IV use a 4:3 sensor; and the iPhone Camera app offers 1:1, 4:3 and 16:9. How much each shape loses when printed to fill common sizes:
| Print (in) | 3:2 (camera) | 4:3 (iPhone) | 16:9 (video) |
|---|---|---|---|
| 4 × 6 | None | 11% | 16% |
| 5 × 7 | 7% | 5% | 21% |
| 8 × 10 | 17% | 6% | 30% |
| 8.5 × 11 | 14% | 3% | 27% |
| 11 × 14 | 15% | 5% | 28% |
| 12 × 12 | 33% | 25% | 44% |
| 16 × 20 | 17% | 6% | 30% |
| 20 × 30 | None | 11% | 16% |
The percentage is the share of the photo trimmed off to fill the print edge to edge. To avoid it, crop the photo yourself before ordering, or ask for a print with a white border. The aspect ratio calculator works out the exact crop for any size.
Picture frame sizes and mat openings
Frame USA sizes all of its frames by the opening, so an 8 × 10 frame holds an 8 × 10 print with no mat and measures more than 8 × 10 on the outside. A mat takes a smaller print, and its window is cut a little smaller than the print so the edges don't fall through. In Frame USA's chart each window is half an inch shorter in both directions than the print, a quarter inch of overlap per side:
| Frame (in) | Print with mat (in) | Mat opening (in) |
|---|---|---|
| 5 × 7 | 3.5 × 5 | 3 × 4.5 |
| 8 × 10 | 5 × 7 | 4.5 × 6.5 |
| 10 × 20 | Three 4 × 6 | 3.5 × 5.5 (each) |
| 11 × 14 | 8 × 10 | 7.5 × 9.5 |
| 16 × 20 | 11 × 14 | 10.5 × 13.5 |
Frame USA's 32 standard frame sizes, in inches: 4×6, 4×7, 4×12, 5×5, 5×7, 7×7, 8×8, 8×10, 8.5×11, 8×12, 9×12, 10×13, 10×20, 11×14, 11×17, 12×12, 12×16, 12×18, 13×19, 14×18, 12×36, 16×20, 18×24, 20×24, 20×28, 22×28, 20×30, 24×30, 24×36, 27×39, 27×40, 27×41. Anything else is a custom size there.
Paper sizes: Letter, A4 and 13 × 19
Home printers take office paper sizes as well as photo sizes. Letter is the US standard; A4 is part of the ISO 216 A series used in most other countries, and is a little narrower and longer.
| Paper | Inches | Millimeters | Ratio |
|---|---|---|---|
| Letter | 8.5 × 11 | 216 × 279 | 17:22 |
| Legal | 8.5 × 14 | 216 × 356 | 17:28 |
| Ledger (tabloid) | 11 × 17 | 279 × 432 | 11:17 |
| A4 | 8.3 × 11.7 | 210 × 297 | 1.41:1 |
| 13 × 19 (A3+) | 13 × 19 | 330 × 483 | 13:19 |
Canon's PIXMA PRO-200S, our budget photo printer pick, takes Letter, Legal, 11 × 17 and 13 × 19 paper and prints borderless up to 13 × 19 inches, big enough for a 12 × 18 print. See our photo printer guide for 13-inch and 17-inch models.
Instant film sizes: Instax and Polaroid
Instant prints have a fixed size set by the film, with a white border around the picture. Sizes as Fujifilm and Polaroid list them:
| Film | Print (mm) | Picture (mm) | Picture (in) |
|---|---|---|---|
| Instax Mini | 86 × 54 | 62 × 46 | 2.44 × 1.81 |
| Instax Square | 86 × 72 | 62 × 62 | 2.44 × 2.44 |
| Instax Wide | 86 × 108 | 62 × 99 | 2.44 × 3.9 |
| Polaroid i-Type, 600 and SX-70 | 107.5 × 88.5 | 78.9 × 76.8 | 3.11 × 3.02 |
| Polaroid Go | 66.6 × 53.9 | 47 × 46 | 1.85 × 1.81 |
A whole Instax Mini print is 3.39 × 2.13 inches, between the two wallet sizes, and an Instax Wide print is 4.25 × 3.39 inches. Compare the cameras in our instant camera guide.
How this chart works
Sizes come from each lab's and maker's own size pages, checked October 19, 2026. Centimeters are inches × 2.54. Pixels are inches × PPI, rounded to the nearest pixel, and ratios are each size reduced to whole numbers. Crop percentages assume the photo is scaled to cover the print and centered, with its long side on the print's long side. The calculator rates each size by the PPI the photo delivers after that crop, against the lab figures above. Labs change their size lists; check the order page for the exact size before you buy a frame.
