Textile Calculators
Denier Calculator
Convert filament yarn weight and length into Denier, Tex, and Decitex simultaneously using the standard direct numbering system formulas.
Dye Bath Liquor Ratio Calculator
Calculate the required dye bath water volume based on fabric weight and the desired liquor-to-goods ratio.
Fabric Air Permeability Calculator
Calculate fabric air permeability in mm/sec based on airflow rate and test area, a standard breathability measurement.
Fabric Cost Calculator
Calculate total fabric needed and total cost from per-unit consumption, order quantity, price per meter, and a waste percentage.
Fabric Shrinkage Calculator
Calculate fabric shrinkage percentage from a wash test, or work backward to find the cutting length needed to hit a target finished size.
Fabric Tensile Strength Calculator
Calculate fabric tensile strength in MPa based on breaking load, fabric width, and thickness from a tensile test.
Fabric Weight Calculator
Calculate total fabric weight in grams and kilograms from length, width, and GSM, for freight quotes and production planning.
Fabric Yield Calculator
Calculate how many garments a fabric roll yields from its total area and area per garment, plus the leftover fabric area.
GSM Calculator
Measure GSM from a fabric sample's weight and area, or convert between GSM and ounces per square yard using the standard factor.
GSM to Ounces Per Square Yard Calculator
Convert fabric weight from GSM (grams per square meter) to ounces per square yard, common in US textile trade.
Knitting Gauge Calculator
Calculate the correct number of stitches to cast on for a target finished width based on your personal knitting gauge swatch.
Loom Efficiency Calculator
Calculate loom efficiency as actual picks woven against theoretical maximum picks from loom speed and run time.
Loom Width Utilization Calculator
Calculate how efficiently a loom's full width is being utilized based on the fabric width being produced.
Tex Count Calculator
Calculate yarn count in Tex, a direct yarn numbering system, based on yarn mass and length.
Textile Waste Percentage Calculator
Calculate the percentage of fabric wasted during garment cutting and production based on fabric purchased versus fabric used.
Thread Consumption Calculator
Estimate thread needed for a seam based on seam length, stitch type, and waste allowance, using consumption ratios by stitch class.
Thread Count Calculator
Calculate fabric thread count by adding warp and weft threads per inch, the standard weave density measurement for woven fabric.
Warp Yarn Requirement Calculator
Calculate total warp yarn needed for a weaving project based on fabric width, ends per inch, fabric length, and waste allowance.
Yarn Count Calculator
Convert yarn weight and length into Tex, Denier, Nm, and Ne count simultaneously, covering both direct and indirect numbering systems.
Yarn Twist Multiplier Calculator
Calculate yarn twist multiplier (TM), which normalizes turns-per-inch against yarn fineness for fair comparison across yarn counts.
Fabric Weight Is Not a Feeling, It Is a Number
"Lightweight" and "heavyweight" fabric descriptions are subjective until you attach GSM (grams per square meter) — the actual standardized measure of fabric density used across the textile industry. These ten calculators cover fabric weight, yield, and yarn measurement math.
GSM Ranges by Fabric Type
| Fabric Type | Typical GSM Range |
|---|---|
| Chiffon / Voile | ~30-60 GSM |
| Quilting Cotton | ~130-150 GSM |
| Denim | ~300-400+ GSM |
GSM directly affects drape, opacity, and durability, which is why a pattern written for quilting cotton will not behave the same way if cut from chiffon at a third of the weight. Calculate GSM directly from a fabric sample with the GSM Calculator.
