How we calculate this
Methodology and source handling
We calculate pixel dimensions from the visible size values, aspect ratios, DPI/PPI formulas, and source notes on this page.
Photo print sizes
Common photo print sizes table
Use these sizes as starting points for lab prints, home printing, frames, and quick source-file checks.
| Print size | Physical size | Aspect ratio | 300 PPI target | Crop note |
|---|---|---|---|---|
| 4x6 | 4 x 6 in | 2:3 | 1200 x 1800 px | Usually fits 2:3 camera files. |
| 5x7 | 5 x 7 in | 5:7 | 1500 x 2100 px | Often needs a small crop from 2:3 photos. |
| 8x10 | 8 x 10 in | 4:5 | 2400 x 3000 px | Needs a stronger crop from 2:3 photos. |
| Passport | Country-specific | Varies | Use the official country size | Confirm rules with the issuing authority. |
Pixels
Pixel dimensions by 150, 300 and 600 PPI
Multiply the print width and height by the PPI target. Use 300 PPI for most sharp photo prints.
| Print size | 150 PPI | 300 PPI | 600 PPI |
|---|---|---|---|
| 4x6 | 600 x 900 px | 1200 x 1800 px | 2400 x 3600 px |
| 5x7 | 750 x 1050 px | 1500 x 2100 px | 3000 x 4200 px |
| 8x10 | 1200 x 1500 px | 2400 x 3000 px | 4800 x 6000 px |
| 2x2 passport | 300 x 300 px | 600 x 600 px | 1200 x 1200 px |
Crop guidance
Aspect ratio, source files and passport caveats
4x6 uses 2:3, 5x7 uses 5:7, and 8x10 uses 4:5. Any mismatch forces a crop or white borders.
Use the highest-resolution source file, avoid screenshot exports, and resize only after choosing the final print ratio.
Passport rules can include head size, background, expression, file size, and upload limits beyond the photo dimensions.

Photo Sizes entries
The most common photo print sizes are 4 × 6 in, 5 × 7 in and 8 × 10 in. A 4 × 6 photo uses a 2:3 aspect ratio and needs 1200 × 1800 px at 300 PPI. A 5 × 7 photo needs 1500 × 2100 px at 300 PPI. An 8 × 10 photo needs 2400 × 3000 px at 300 PPI. Use this hub when you need the right print size, pixel target, crop ratio or passport-photo reference before exporting or ordering prints.

Details
Which photo size should you choose?
Choose 4 × 6 when you want the classic photo-lab print size. It matches the 2:3 shape used by many cameras, so it often needs less cropping than 5 × 7 or 8 × 10.
Choose 5 × 7 when you want a slightly larger framed print or card. It is narrower than 4 × 6, so a 2:3 image will need a small crop.
Choose 8 × 10 when you want a common portrait or wall-frame size. It uses a 4:5 shape, so a 2:3 camera image must be cropped more noticeably.
Choose passport size only after checking the country-specific rules. Passport photo sizes, head position and editing restrictions vary by country.
Formula
How to calculate pixels for any photo size
Use this formula:
pixels = inches × PPIExample for 5 × 7 at 300 PPI:
5 × 300 = 1500 px
7 × 300 = 2100 pxSo a 5 × 7 print at 300 PPI needs 1500 × 2100 px.
Workflow
Recommended workflow
1. Pick the final print size. 2. Check the aspect ratio before resizing. 3. Crop intentionally if the source image has a different shape. 4. Use 300 PPI for a high-quality standard print target. 5. Export as JPEG for normal photo printing unless the lab requests another format. 6. Check the print lab’s upload requirements before ordering.

FAQ
Common questions
What is the best pixel size for a 4 × 6 photo?
Use 1200 × 1800 px for a 4 × 6 photo at 300 PPI. Use 2400 × 3600 px if you need a 600 PPI archival or specialist workflow.
Is 300 PPI always required for photo prints?
No. 300 PPI is a common high-quality target for standard photo prints, but the right value depends on print process, viewing distance and the print lab’s requirements.
Why does my photo get cropped when I order prints?
Your image is being cropped because its aspect ratio does not match the selected print size. For example, a 2:3 camera photo fits 4 × 6, but it does not perfectly fit 5 × 7 or 8 × 10.
Should I use inches or pixels when preparing a photo print?
Use both. The inches define the final print size, and the pixels define how much image detail is available for that print size.

Pixel dimensions are calculated from physical print dimensions multiplied by the selected PPI. Passport requirements vary by country and should be verified with the issuing authority.
