Measure the area your pieces cover, not the artboard. Sewpress uses 10 mm overlap and 10 mm margins by default; most home printers can't print closer than about 6 mm to the edge.
Green: your pattern area. Dashed: printable area of each page, 190 × 277 mm.
How the count works
Each page prints an area the size of the paper minus its margins. Neighbouring pages share an overlap, so every page after the first adds the printable width minus the overlap. A 706 × 917 mm trouser on A4 with 10 mm margins and 10 mm overlap needs 4 pages across and 4 down: 16 pages, before any blank ones are skipped.
Want fewer pages? Shrink the margins (most printers manage 6 mm), nest the pieces closer, or offer an A0 copyshop file alongside the tiles.
Sewpress tiles, lays out and measures every file from one master.
