Sample to finished fabric weight calculator
Scale a finished sample’s mass by area to estimate the mass of a larger piece of cloth.

How the calculation works
project mass = sample mass × project area ÷ sample area
The estimate assumes the same yarns, structure, sett, beat, and finishing. It does not include loom waste or determine how much warp versus weft to buy. Use the project planner for yarn purchasing.
Full calculation methodologyWorked example
A 10 × 10 sample weighing 25 g predicts 200 g for 20 × 40 cloth with the same construction.
Use the complete weaving planner to connect the dimensions, allowances, and yarn quantities for one project.
