Textile & Fashion Suite
Streamline garment fitting, calculate pattern adjustments, and translate fabric weights and hardware standards used across global apparel manufacturing.
Elastic Stretch Ratio Calculator
Calculate stretch percentages, determine relaxed cutting lengths based on target garment spans, and calibrate swimwear vs. waistband elastics.
1. Determine Elastic Capacity / Ratio
2. Calculate Pattern Cut Length
💡 Tip: Waists are usually cut to 80-85% of body measurement to ensure the band stays snug but comfortable. Seam allowance accounts for sewing the ends together.
This elastic can stretch up to 1.5x its natural length.
Cut length = (32 in body × 80% tension) + 1 in seam overlap.
