The short version
A 5 × 7 photo measures 5 by 7 inches, or 12.7 by 17.78 centimeters. Its portrait ratio is 5:7, and a 300 PPI print requires 1500 × 2100 pixels.
What matters most
- 5:7 is slightly squarer than a 3:2 camera frame.
- A small source crop is normally needed.
- At 240 PPI the target is 1200 × 1680 pixels.
How to apply it
- Select a 5:7 crop preset.
- Move the crop to protect faces and edge details.
- Calculate required pixels from the chosen density.
- Check the print provider's bleed and file requirements.
Reference table
| Density | Portrait pixels | Landscape pixels |
|---|---|---|
| 150 PPI | 750 × 1050 | 1050 × 750 |
| 240 PPI | 1200 × 1680 | 1680 × 1200 |
| 300 PPI | 1500 × 2100 | 2100 × 1500 |
Use exact dimensions and units in production notes; familiar labels can describe more than one standard.
Common mistakes to avoid
- Treating 5×7 as interchangeable with 4×6.
- Upscaling a small messaging-app image without checking detail.
- Ignoring lab trim tolerance.

Use a calculator to check the numbers against your own source and destination instead of relying on a generic preset.

Frequently asked questions
What aspect ratio is a 5×7 photo?
Exactly 5:7 in portrait or 7:5 in landscape.
How many megapixels is 1500 × 2100?
It contains 3.15 million pixels, or 3.15 MP.
Does a 4×6 image fit 5×7?
Not exactly. A 3:2 source needs a modest crop to become 7:5.
