Elastic-waist skirt

Start from the app’s rectangular-piece template. Choose a size, adjust your measurements and calculate the fabric before cutting.

How the calculation works

Each piece is cut 1.5 cm larger on every edge, so its width and its length each grow by 3 cm.

A worked example: Elastic-waist skirt, Hip 102 cm · 40 in

Fabric width: 110 cm
Seam allowance per edge: 1.5 cm
Usable fabric width: 110 cm

Skirt panel × 2 — Width: 77 cm + 2 × 1.5 cm = 80 cm · Length: 60 cm + 2 × 1.5 cm = 63 cm
Waistband × 2 — Width: 8 cm + 2 × 1.5 cm = 11 cm · Length: 77 cm + 2 × 1.5 cm = 80 cm

Where each piece sits on the fabric

Waistband 1: 11 cm × 80 cm — x 0 cm · y 0 cm
Waistband 2: 11 cm × 80 cm — x 11 cm · y 0 cm
Skirt panel 1: 80 cm × 63 cm — x 22 cm · y 0 cm
Skirt panel 2: 80 cm × 63 cm — x 22 cm · y 63 cm

x: distance from the fabric edge · y: distance along the fabric length

Required: 126 cm · 1.26 m · 1.38 yd
Unused fabric area (%): 14.6

A worked example: Elastic-waist skirt, Hip 102 cm · 40 in (Inches)

Fabric width: 44 in
Seam allowance per edge: 0.625 in
Usable fabric width: 44 in

Skirt panel × 2 — Width: 30 in + 2 × 0.625 in = 31.25 in · Length: 24 in + 2 × 0.625 in = 25.25 in
Waistband × 2 — Width: 3 in + 2 × 0.625 in = 4.25 in · Length: 30 in + 2 × 0.625 in = 31.25 in

Required: 50.5 in · 1.28 m · 1.4 yd
