Choose the size for the job
Compare the composition at 8 × 10 and 8 × 12 before ordering a frame. The extra two inches on the long edge can preserve space around a group or more of a landscape. That benefit only applies when the source itself has the matching shape.
| Measurement | Value |
|---|---|
| Inches | 8 × 12 |
| Centimetres | 20.32 × 30.48 |
| Millimetres | 203.2 × 304.8 |
| Short-edge-to-long-edge ratio | 2:3 |
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 | 1,200 × 1,800 |
| 240 | 1,920 × 2,880 |
| 300 | 2,400 × 3,600 |
A worked example
A 6000 × 4000 landscape file fits a 12 × 8 inch print at 500 PPI with no necessary crop. Changing the target to 10 × 8 retains 5000 × 4000 pixels and removes one-sixth of the original area. The PPI remains 500 in that comparison because the eight-inch edge still uses 4000 pixels.
Before you print
At 8 × 12 inches, the long edge is 304.8 mm. It is longer than the 297 mm long edge of A4, so the full image cannot fit on one A4 sheet at actual size, even before printer margins. Use a larger sheet or deliberately choose a smaller print.
