How this calculator works
The checker automatically evaluates portrait and landscape orientation and uses the better fit. Differences in aspect ratio may still require cropping.
How to use the Photo Print Size Checker
- Choose a photo from your device.
- Review the effective PPI for each common photo size.
- Select a size with an acceptable quality rating and check whether the aspect ratio requires cropping.
Worked example
A 3000 × 2000 pixel photo matches the 3:2 ratio of a 6 × 4 inch print and provides 500 PPI without cropping.
Accuracy note: A high PPI rating does not guarantee a perfect composition. Standard photo sizes can still crop images with a different aspect ratio.
Frequently asked questions
Which photo sizes are checked?
The tool checks 4×6, 5×7, 8×10, 8.5×11, 11×14, 12×18, 16×20, and 20×30 inch prints.
Will the photo be cropped?
Many standard print sizes use different aspect ratios. The PPI rating does not eliminate the need to crop or add borders.
Is the photo private?
Yes. It stays in browser memory and no upload request exists.
Why a high PPI result can still need cropping
Example: a 6000 × 4000 image has a 3:2 aspect ratio and fits a 4 × 6 or 12 × 18 print naturally. An 8 × 10 print has a 4:5 ratio, so part of the long edge must be cropped even if the image has more than enough pixels.
What happens to a typical 3:2 photo
Most interchangeable-lens cameras produce a 3:2 image. The crop percentages below describe the total removed from one image dimension when the photo fills the paper. A centered crop removes about half from each side.
| Print size | Minimum at 300 PPI | Crop from a 3:2 photo |
|---|---|---|
| 4 × 6 in | 1200 × 1800 px | No ratio crop |
| 5 × 7 in | 1500 × 2100 px | 6.7% of the long edge total |
| 8 × 10 in | 2400 × 3000 px | 16.7% of the long edge total |
| 8.5 × 11 in | 2550 × 3300 px | 13.7% of the long edge total |
| 11 × 14 in | 3300 × 4200 px | 15.2% of the long edge total |
| 12 × 18 in | 3600 × 5400 px | No ratio crop |
| 16 × 20 in | 4800 × 6000 px | 16.7% of the long edge total |
| 20 × 30 in | 6000 × 9000 px | No ratio crop |
For a 6000 × 4000 image going to 8 × 10, a full-bleed centered crop keeps roughly 5000 × 4000 pixels and removes about 500 pixels from each end of the long edge. If a face or text sits near an edge, add borders instead of forcing the crop.
Check before ordering
- Inspect focus, faces, text, compression, and noise at 100% view.
- Use the lab's crop preview and keep important content away from cut edges.
- Confirm whether the listed size is the paper size, image area, or finished frame opening.
