Textile & Fabric Calculators
Free, practical tools for anyone who works with cloth — convert fabric weight and yarn counts, estimate yardage, read a thread count and cover factor, and plan for shrinkage before you cut.
Fabric Weight Converter (GSM ↔ oz/yd²)
Convert a fabric's areal weight between metric GSM and imperial ounces per square yard, and see which weight band it falls into — the fast way to compare cloths quoted in different units.
Fabric Weight from Dimensions
Turn a fabric's GSM and a roll or cut size into a total weight in kilograms and grams, plus weight per running metre — for costing by the kilo and verifying a supplier's roll weight.
Denier / Tex / Dtex Yarn Count Converter
Move a yarn spec between denier, tex, and dtex, and read the equivalent metric (Nm) and cotton (Ne) counts — so filament and spun-yarn specs finally speak the same language.
Fabric Yardage Calculator
Work out how much fabric to buy from the area you need, the bolt's usable width, and a waste allowance — the answer in metres and yards, plus how many whole rolls.
Thread Count & Cover Factor Calculator
Add ends and picks per inch for a woven fabric's thread count and warp:weft balance, and — with yarn counts — the Peirce cover factor that shows how tightly it is actually woven.
Fabric Shrinkage Calculator
Measure shrinkage from a before/after wash, or work backwards to the length to cut before washing so the finished piece lands at exactly the size you want.
