Purpose-built estimates with the assumptions visible—so you know what the number includes and what still needs checking.
01Fabric yardageEstimate fabric yardage or metres from piece size, quantity, usable fabric width, and a cutting allowance.02Width conversionConvert a fabric length requirement between widths while preserving total fabric area.03Pattern repeatEstimate fabric needed when every cut row must align to a vertical pattern repeat.04GSM ↔ oz/yd²Convert textile basis weight between grams per square metre (GSM) and ounces per square yard.05Roll length & weightEstimate fabric roll weight from length, width, and GSM—or calculate length from roll weight.06Marker utilizationCalculate marker utilization and fabric loss from marker dimensions and total pattern-piece area.07Shrinkage allowanceCalculate pre-shrink cut dimensions needed to reach a target size after lengthwise and widthwise shrinkage.08Seam allowanceAdd an even seam allowance to a rectangular finished panel and calculate total cut area for a quantity.09Pleats & gathersEstimate cut width from finished width, fullness ratio, side hems, and panel quantity.10Thread consumptionEstimate sewing thread consumption from seam length, product quantity, stitch construction, and waste allowance.
A production-minded method
Useful estimates.
Visible limits.
Keep the allowance explicit
Separate geometry from contingency so cutting loss, defects, shrinkage, and handling are not silently mixed together.
Verify before production
Calculators support planning. A sample, marker, test report, and supplier confirmation remain the authority for important work.
