Frame a portrait
Preview a 4:5 or 3:2 print and keep the subject away from the cut edge.

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.
Fit A-series paper
See how a photograph changes when fitted to A4, A3 or another √2 paper ratio.
Protect resolution
Check the retained pixels and maximum 300 PPI size before ordering a print.
The calculation
How it works
The tool compares the source width-to-height ratio with the target. It removes only the excess width or height needed to match the new shape.
Crop position changes which pixels are retained; it does not stretch the image. The exported crop keeps the remaining source resolution.
Quick reference
Common print proportions
Two prints can share a ratio even when their physical sizes differ.
| Ratio | Example sizes | Typical crop behaviour |
|---|---|---|
| 4:5 | 8 × 10, 16 × 20 in | Common portrait crop |
| 3:2 | 4 × 6, 12 × 18 in | Matches many cameras |
| 1:1 | 8 × 8, 12 × 12 in | Square crop |
| 1:√2 | A5, A4, A3 | A-series paper |
| 16:9 | Digital displays | Wide landscape crop |
Check the numbers
3:2 photo to an 8 × 10 print
The target is 4:5, so some width is removed. Move the horizontal focus to protect the subject.
Square image to A4 portrait
The A-series target is taller, so the crop removes width from the square source.
6000 × 4000 px at 4:5
The crop retains approximately 3200 × 4000 pixels, enough for about 10.7 × 13.3 inches at 300 PPI.
Before you export
Common mistakes to avoid
Cropping after adding text
Important type or logos near an edge can be cut. Resolve the crop before final layout work.
Confusing ratio and size
A 4:5 ratio describes shape, not physical dimensions. Choose the final inches or millimetres separately.
Ignoring frame overlap
Frames and printers can hide a little more at the edge. Keep critical content inside a safe area.
Preview a print crop before losing the edges. FAQ
Is the image uploaded?
No. The preview and crop export are created locally in your browser.
Does cropping reduce quality?
It removes pixels outside the target shape. Remaining pixels are not enlarged, but the maximum high-quality print size can become smaller.
Which ratio should I choose?
Use the ratio of the final print or frame opening. Confirm exact dimensions with the printer or frame supplier.
