Hex and square grid generator

You pick the cell size: a square’s side, or a hex’s width across its flat sides (1 inch, 25.4 mm, is the usual size for miniatures). The tool fits as many whole cells as the board holds inside a 3 mm margin and centres them, and shows how many columns and rows you get.

Point-up hexes have a corner at the top and sit in rows, every other row shifted half a hex. Flat-top hexes have a flat side at the top and sit in columns, every other column shifted. The offset picks whether the odd or even rows (or columns) are the shifted ones, which matters if you number cells to match a rulebook.

The PDF splits it over several pages, starting with an assembly map that names each piece. The pages overlap by 10 mm (you can pick 5–20 mm) and carry crosshairs in the overlap: trim one page along its overlap, line its crosshairs up with the next page’s and glue. Print at 100% (“Actual size”) so the pieces meet.

Yes. Labels can be A1 style (a letter for the row, a number for the column) or x,y coordinates starting at 0,0, printed near the top of each cell in the colour you pick.

Yes. Download the PNG at 300 DPI (or 150 for a smaller file) and paint your map on it in any image editor. Leave the cell fill off and the board white for a plain grid.
