Map splitter
Cuts a large map into A4 pages at its real printed size, so a 25 mm square stays 25 mm. Every page keeps a 10 mm white border and is labelled row–column in its corners.

Sizes that fill the pages
3366 × 3276 px → 3 × 2 pages, 57 × 55.5 cm.3366 × 4914 px → 3 × 3 pages, 57 × 83 cm.
Any other size works too; the last row and column are just partly empty.
In Procreate
Make the canvas 570 × 555 mm (or 570 × 832 mm) at 150 DPI. A 25 mm grid of the same size lines up with it.
Printing
Print at 100 % or actual size, never “fit to page”. Trim along one edge of the border and overlap the next page.
