When to use it
Start with the result you need
This calculator is most useful when one part of the print specification is known and another needs to be checked.
Sell downloadable wall art
Check which standard sizes a customer can print without excessive enlargement or unexpected cropping.
Choose a frame ratio
See how much of the image a popular frame size removes before committing to the crop.
The calculation
How it works
For each standard size, the calculator first matches the image’s portrait or landscape orientation. It then applies a centred crop to the print’s aspect ratio and calculates effective PPI = remaining pixels ÷ print inches.
A result of 300 PPI is a strong target for a close-viewed photo. Results from 240 to 299 PPI are usually very good, while larger display prints may work at lower density when viewed from farther away.
Quick reference
Why common print sizes crop differently
Print dimensions do not all share the same shape. A camera image may fit one family perfectly and require cropping for another.
| Print size | Aspect ratio | Typical use | Crop risk |
|---|---|---|---|
| 4 × 6 in | 3:2 | Standard camera photo | Low for 3:2 images |
| 5 × 7 in | 7:5 | Small framed print | Moderate |
| 8 × 10 in | 5:4 | Portrait and frame | Higher for 3:2 images |
| 11 × 14 in | 14:11 | Portrait and art print | Moderate |
| 12 × 18 in | 3:2 | Large camera photo | Low for 3:2 images |
| 16 × 20 in | 5:4 | Wall art | Higher for 3:2 images |
| 20 × 30 in | 3:2 | Large wall print | Low for 3:2 images |
The crop percentage is an area estimate for a centred crop. Repositioning the crop changes composition, not the amount removed.
Check the numbers
6000 × 4000 camera image
The native 3:2 ratio fits 4 × 6, 12 × 18 and 20 × 30 without cropping. An 8 × 10 print removes part of the long edges.
4000 × 5000 art file
The 4:5 image ratio fits 8 × 10 and 16 × 20 directly, making those strong choices for downloadable artwork.
2400 × 3000 portrait
At 8 × 10 inches the file provides 300 PPI. Enlarging to 16 × 20 reduces the effective density to 150 PPI.
Before you export
Common mistakes to avoid
Choosing by megapixels alone
Megapixels describe total image area, but print quality depends on the pixels available along each final print dimension.
Ignoring the crop
A high-resolution file can still lose important content when the photo and paper use different aspect ratios.
Upscaling before checking the original
Calculate from the original edited pixels first. Resampling creates more pixels but does not restore missing detail.
Choose the best photo print size for your image. FAQ
What is the best PPI for photo printing?
300 PPI is a common high-quality target for close viewing. Many labs produce very good results from 240 PPI, while larger wall prints can use less depending on viewing distance and subject detail.
Why does an 8 × 10 crop my camera photo?
Most cameras produce a 3:2 or 4:3 image, while 8 × 10 uses a 5:4 ratio. The shapes differ, so part of the image must be cropped or blank borders must be added.
Does the calculator upload my photo?
No. It only needs the pixel width and height, so no image leaves your device.
