Textile & apparel calculators
Fabric, yarn and garment maths using the industry’s standard definitions, with unit systems spelled out.
Costing
- Garment Costing CalculatorBuild a garment cost sheet from fabric, trims, CM, processes and overheads, then set the FOB price per piece and per dozen for your profit margin.
- Needle Consumption CalculatorEstimate how many sewing machine needles a floor needs for a period from machines, needles per machine, change frequency and breakage allowance.
- Apparel Packaging Cost CalculatorAdd up garment packing costs (polybags, hangers, tags, cartons, packing labour and fixed charges) for an order, per piece and per dozen.
- Garment Export FOB Price CalculatorBuild a garment FOB price from your own fabric, trims, CM, washing, packing and port costs, plus overhead, profit markup and buying commission.
Cutting
Dyeing
- Textile Dye Recipe CalculatorTurn an exhaust dyeing recipe into weighed amounts: dyes as % on weight of fabric, salt, soda ash and auxiliaries as g/L of the bath volume.
- Dye Bath Liquor Ratio CalculatorFind the material-to-liquor ratio (MLR) of a dye bath, the water needed for a fabric load, or how much fabric a bath volume can take.
Dyeing & processing
- Textile Dyeing Water Consumption CalculatorEstimate water use per dyeing batch from the fabric weight, the dye-bath liquor ratio and the number of rinse and wash baths, plus daily volume and cost.
- Textile Colour Yield CalculatorCalculate colour yield as K/S with the Kubelka–Munk equation from reflectance, and the relative colour strength of a dyed sample against a standard.
Fabric
- Fabric Consumption per Garment CalculatorEstimate fabric needed per garment from pattern block sizes, allowances, GSM and cutting wastage, in grams, kg per dozen and running metres.
- Fabric GSM CalculatorFind fabric GSM (grams per square metre) from a cut sample, from weight per running metre and width, or from a woven construction; also gives oz/yd².
- Fabric Width Conversion CalculatorConvert the fabric length a pattern asks for at one width (say 45 in) into the length you need at another width (say 60 in), by equal area.
- Fabric Shrinkage Percentage CalculatorWork out fabric shrinkage after washing from benchmark marks measured before and after, with the pattern allowance needed to compensate.
- Fabric Roll Weight CalculatorCalculate a fabric roll’s net and gross weight from GSM, width and length, or work out the metres on a roll from its weight.
Fabric costing
- Fabric Price per Metre CalculatorConvert a fabric price per kilogram into price per metre, per yard and per square metre from the fabric’s GSM and width in cm or inches.
- Fabric Price per Kilogram CalculatorConvert a fabric price per metre or per yard into price per kilogram and per square metre from the fabric’s GSM and width.
Fabric planning
- Fabric Lot Quantity CalculatorWork out how much fabric to book for a garment order from the order quantity, consumption per garment, extra cut, wastage, shrinkage and roll size.
- Fabric Wastage Percentage CalculatorFind cutting-room fabric wastage from fabric issued, fabric returned, garments cut and marker consumption, as a share of fabric used and over standard.
- Pattern Piece Area CalculatorFind the area and perimeter of a pattern piece from its outline points, then the fabric area and length for an order at your fabric width and marker efficiency.
Garment production
- Sewing Line Efficiency CalculatorMeasure sewing line efficiency as (output × SMV) ÷ (operators × working minutes), with the 100% target and pieces per hour.
- Standard Minute Value (SMV) CalculatorCalculate the standard minute value (SMV/SAM) of a sewing operation from timed cycles, a performance rating and allowances, plus pieces per hour.
- Garment Operator Efficiency CalculatorCalculate a sewing operator’s efficiency from pieces produced, operation SMV and minutes attended, separating off-standard time such as breakdowns.
Knitting
Pattern & sizing
Production planning
- Apparel Order Quantity Breakdown CalculatorSplit an apparel order into sizes by a size ratio so the pieces add up exactly, and add an extra cutting allowance for rejects and shortages.
- Garment Production Target CalculatorSet a sewing line’s daily and hourly target from the garment SMV, operators, working hours and planned efficiency, and see days to finish an order.
- Textile Machine OEE CalculatorCalculate OEE for a loom or textile machine from planned time, stoppages, rated picks per minute, fabric woven and first-quality metres.
- Textile Production Lead Time CalculatorPlan a garment order’s ex-factory and arrival dates from the order date, stage durations in working days, your working week and transit time.
Quality
Retail & margin
Trims & accessories
Weaving
- Warp Yarn Requirement CalculatorWork out the warp yarn weight for a woven fabric from ends per inch, width, selvedge ends, length, crimp, wastage and yarn count in Ne, tex or denier.
- Weft Yarn Requirement CalculatorCalculate the weft yarn weight for a woven fabric from picks per inch, reed width, fabric length, wastage and the weft count in Ne, tex or denier.
Yarn
- Yarn Count Ne to Tex ConverterConvert English cotton count (Ne) to Tex, and back, using the exact definition Tex = 590.54 ÷ Ne; also shows denier, decitex and metric count Nm.
- Yarn Count Denier to Tex ConverterConvert filament or fibre denier to tex and decitex (and back), with the cotton count equivalent and denier per filament from the filament number.
