No ratio crop after orientation is matched

Why Photos Crop at Different Print Sizes
Compare common camera and print aspect ratios, see which sizes fit, and learn when to crop, add borders or choose another print.
Quick answer
Match the source and print aspect ratios to avoid cropping. A common 3:2 photo fits 4 × 6 and 12 × 18, loses about 6.7% at 5 × 7, and loses about 16.7% at 8 × 10 or 16 × 20 when the print is filled edge to edge.

Decision table
How a 3:2 camera image fits common edge-to-edge prints
| Print size | Print ratio | Image retained | Likely decision |
|---|---|---|---|
| 4 × 6 | 2:3 | 100% | Direct fit after orientation is matched |
| 5 × 7 | 5:7 | About 93.3% | Small crop or narrow borders |
| 8 × 10 | 4:5 | About 83.3% | Reposition the 16.7% crop carefully |
| 11 × 14 | 11:14 | About 84.8% | Preview the non-standard crop |
| 12 × 18 | 2:3 | 100% | Direct 3:2 enlargement |
| 16 × 20 | 4:5 | About 83.3% | Same shape and crop as 8 × 10 |
Aspect ratio describes shape, not size
A 4 × 6 and a 12 × 18 have the same 2:3 ratio even though one is much larger. An 8 × 10 and a 16 × 20 both use 4:5, so they share a shape but require different pixel counts.
Orientation does not change the ratio match. A 3:2 landscape becomes 2:3 in portrait while keeping the same proportions.
Fill, fit or add a border
Fill covers the paper and crops image content that falls outside the target ratio. Fit shows the complete image and can leave borders on two sides. Expanding the canvas creates a deliberate border while preserving the source composition.
None is automatically correct. The subject placement, frame, lab product and intended design decide the best option.
Crop position protects the subject
A centered crop is only a mathematical default. Faces, text, horizons and important objects may need the crop shifted horizontally or vertically.
Preview the exact print ratio, then inspect the edges at the final size. Labs can also apply a small production crop for borderless output.
Cropping changes effective PPI
Cropping removes pixels. A 6000 × 4000 px 3:2 image cropped to 4:5 retains approximately 5000 × 4000 px. Calculate print resolution from those remaining dimensions, not from the original file.
Choose a ratio-friendly size when composition matters
If an edge-to-edge crop damages the image, choose a print that matches the camera ratio, add a border, or extend the canvas intentionally. A 3:2 source naturally fits 4 × 6, 12 × 18 and other 2:3 sizes.
Practical workflow
Use this order before you export.
- Identify the source image ratio.
- Select the exact print size and orientation.
- Compare fill and fit, then position the subject-safe crop.
- Calculate effective PPI from the pixels that remain.
