Read a sequence from left to right
A wide sheet gives more horizontal room for a timeline sketch, repeated pattern, or a sequence of handwritten marks. The starting twelve columns provide a clear progression across the page.
The tool creates one continuous grid. It does not stitch multiple sheets together or generate separate panels that automatically align when taped side by side.
Canvas width is different from borderless printing
The grid spans its exported canvas, but a printer can still leave unprinted margins around that image. Borderless output depends on the printer and the application used for printing.
If you need two physical copies to align, print them at the same scale and measure a few cell intervals first. Avoid separately stretching either image, because that changes the spacing and can make neighboring copies disagree.
