Calculate fabric yardage for cosplay costumes and sewing projects. Estimate material needed by garment type, size, and fabric width.
Calculate EVA foam sheet quantity for cosplay armor and props. Estimate sheets by piece area, thickness, and waste factor.
Calculate cosplay wig length needed for character hairstyles. Convert character height ratio to inches for proper wig ordering.
Compare your chest, waist, or shoulder width to the reference model measurement. Apply uniform scale or per-axis scaling for non-proportional adjustment.
Scale % = (Your measurement ÷ Reference measurement) × 100Uniform scaling preserves proportions. Separate axis scaling adjusts width without changing height — useful when reference model differs in build.
Uniform: same % all axes | Axis: X%, Y%, Z% separatelyEVA foam 5mm adds 10mm total circumference. Size armor exterior dimensions to accommodate foam, Worbla, or resin thickness.
Interior dimension = Body + (2 × Material thickness)Updated: July 2026
Reference head circumference 58 cm, yours 62 cm — scale to 107% uniformly before printing and assembling foam pieces.
Reference chest 96 cm, yours 110 cm width but same height — scale X-axis 115%, keep Y/Z at 100% for proportional shoulder fit.
Scale each piece individually using relevant body measurement — chest plate from chest, greaves from calf circumference, pauldrons from shoulder width.
Cosplay armor patterns must scale from reference files to fit your body measurements. Enter your key body dimensions and reference/template measurements to calculate the scaling percentage for Pepakura, foam, or 3D-printed armor pieces.
