Physical size (in) = pixels ÷ DPI. With bleed b (mm) and kiss-cut margin m (mm) per side, the cell on the sheet is (size + 2b + 2m). Stickers per sheet = floor(sheetW / cell.w) × floor(sheetH / cell.h).
Per-sticker cost = sheet cost ÷ count. Etsy price = cost × markup (3× is the common minimum for handmade).
