A pegboard is not the same as a grid
A 60×60 grid has 3600 possible bead positions. At 5mm pitch it occupies about 30×30cm before ironing, not 60cm. Covering the full grid with non-overlapping 29-cell boards requires 3×3 boards, or nine in total.
Count beads, not empty background
Erased cells need no beads, while white beads still count as material. A sparse design can occupy a smaller bounding area than the full grid. The editor reports actual non-empty counts and occupied bounds separately.
Pixels are not physical dimensions
A larger PNG makes codes easier to inspect but does not add cells. For physical-scale printing, measure your board pitch and verify print scaling. This tool does not provide calibrated, tiled PDFs.
