Choose the size for the job
Use the crop preview to follow a skyline, ridge, or another horizontal subject across the full width. The narrow height can remove much of the foreground and sky. A panorama assembled elsewhere may already fit this shape, but its actual pixel dimensions still determine the print resolution.
| Measurement | Value |
|---|---|
| Inches | 12 × 36 |
| Centimetres | 30.48 × 91.44 |
| Millimetres | 304.8 × 914.4 |
| Short-edge-to-long-edge ratio | 1:3 |
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 | 1,800 × 5,400 |
| 240 | 2,880 × 8,640 |
| 300 | 3,600 × 10,800 |
A worked example
A 6000 × 4000 source filling a landscape 36 × 12 frame retains 6000 × 2000 pixels. Half the original area is removed, and the effective PPI is about 166.67. Keeping the full source inside that frame gives an 18 × 12 inch picture with nine-inch spaces on the left and right.
Before you print
A1’s 841 mm long edge is shorter than this 914.4 mm print. A0 can contain the rectangle in landscape, but a wide-format printer or suitable lab is still required. PrintLilt calculates the geometry; it does not stitch panoramas or create scene detail beyond the source file.
