Fabric cutting layout planner
List your rectangular pieces, such as panels, strips, bags, cushions and quilt backs. Set the bolt width, grain, nap, seam allowance and shrinkage, and Bolt & Grain lays the pieces out to use less fabric. You get the length you'll use and how much to buy. Everything runs in your browser.
Rectangles only. Curved garment pattern pieces are planned by their bounding rectangles, which over-estimates fabric. The layout comes from a packing heuristic, not an optimal nest. When auto layouts are unreliable.
1 · Fabric
Use 0 for length if you haven't bought the fabric yet. Measure width, length and selvage before washing; shrinkage is applied to them.
Usable width:
2 · Pieces
Width runs across the piece. Length runs along its grainline.
3 · Layout
4 · Compare bolt widths
Same pieces and settings laid out on each common width. Purchase lengths are rounded up to ⅛ yd or 10 cm and include shrinkage, plus one repeat when aligning to the repeat. They're estimates: shops cut differently, so add your own margin for straightening the cut end.

The PDF is a scaled overview, printed at a stated ratio such as 1:10 with a scale bar and a 50 mm check bar. It is never silently shrunk to fit, but it is not a full-size pattern. The SVG is drawn at true size in millimetres for projectors or plotters; it isn't tiled for home printers. Rectangles can be measured and cut directly, so v1 doesn't produce a full-size printable pattern.
