Example: a 76 × 42 mm design on a 100 × 70 mm blank, with a 5 mm margin on each edge. Type your own measurements to replace it.

A file can hold pieces laid out with gaps, so its size isn’t the finished size. Changing this choice clears the design size.

Measure the space you will actually use

Measure the flat area you can actually use. Curved edges, seams and hardware can make it smaller than the item’s overall size. Enter that width and height, then the margin you want on each edge. The tool keeps the design’s proportions and tries it turned a quarter when you allow it.
