Fabric changes the character. Check the pattern’s material guidance before buying.
A starting point for fabric
The calculator works out exactly how much to buy for every size and fabric width, measured piece by piece from the full-size A0 pattern.
Before you buy fabric
How much fabric do you need?
Pick the garment, your size and the width of the cloth you're buying.
All calculations are made from the full-size A0 sheet: every panel measured and laid next to each other with the grain running straight, for every size. Then we add 5% (a real cutting table never packs as tight as a computer) and 0.5 m spare, which covers a recut, a flaw in the cloth or a piece that slips off grain, and saves you hunting for a dye lot that's gone. The width you enter is taken as the full roll; 2 cm is left for the selvedge.
Measure something
you already love.

| Garment area | What to compare |
|---|---|
| Chest / waist | Use the same flat or circumference method as the chart |
| Length | Measure between the same start and end points |
| Movement | Allow for layering and the intended silhouette |
