Free calculators for woodwork, framing and material quantities. Get dimensions, layouts and printable plans before you buy or cut.
Illustrative six-panel layout. Enter your own parts in the optimizer.
Explore three tools that turn your dimensions into a useful layout.
Every riser dimensioned, the angle, and the dropped-stringer correction applied.
Pin width adjusted so the spacing divides exactly — printed at 1:1.
Parts placed, offcuts shown, kerf subtracted at every cut line.
No matching calculators. Try a material or a shorter word.
Plywood, MDF, bar stock and trim — every part out of the fewest sheets.
Stairs, roofs, walls and decks. The geometry, drawn and dimensioned.
Tile, concrete, gravel and paint — quantities you can actually order.
Layouts that divide evenly, with templates you print at full size.
