Choose the size for the job
For a large square display, compare a tight subject crop with a looser alternative. A square can create balance around a single subject, but cutting a landscape down to a square discards a substantial part of the scene. The crop preview makes that loss explicit.
| Measurement | Value |
|---|---|
| Inches | 16 × 16 |
| Centimetres | 40.64 × 40.64 |
| Millimetres | 406.4 × 406.4 |
| Short-edge-to-long-edge ratio | 1:1 |
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 | 2,400 × 2,400 |
| 240 | 3,840 × 3,840 |
| 300 | 4,800 × 4,800 |
A worked example
A 6000 × 4000 landscape file filling the square retains 4000 × 4000 pixels. That gives 250 PPI at 16 inches and removes one-third of the original area. A 4800 × 4800 retained square would be needed for a 300 PPI example at this size; changing a metadata field does not supply those pixels.
Before you print
An A2 sheet is 420 mm wide, leaving just 6.8 mm at each side of a centred 16-inch square. If the printer’s usable width is smaller, enlarge the sheet or reduce the print dimensions deliberately. A page-level Fit setting can hide this decision by silently shrinking everything.
