Choose the size for the job
Use this format for an opening that is actually 10 × 12, rather than selecting it because one edge resembles another size. The launch ratio directory does not have a separate 5:6 page, but this entity and the custom crop controls use the exact ratio.
| Measurement | Value |
|---|---|
| Inches | 10 × 12 |
| Centimetres | 25.4 × 30.48 |
| Millimetres | 254 × 304.8 |
| Short-edge-to-long-edge ratio | 5:6 |
Pixel examples
These examples multiply each edge in inches by the stated PPI. They describe pixel counts for the chosen size, not a universal pass or fail rule for appearance. Use the retained pixels after cropping when checking an existing photo.
| Example PPI | Pixels |
|---|---|
| 150 | 1,500 × 1,800 |
| 240 | 2,400 × 2,880 |
| 300 | 3,000 × 3,600 |
A worked example
A 6000 × 4000 landscape image filling a 12 × 10 inch frame retains 4800 × 4000 pixels. That is 400 PPI and a 20% area reduction. Keeping the image whole gives a 12 × 8 inch picture with one inch of space above and below when centred. This is a meaningful composition choice, not a small rounding difference.
Before you print
Do not stretch the original width and height independently to eliminate the border. A circular object would become elliptical. If the crop removes essential content, keep the whole photo or choose the longer 10 × 15 format instead.
