Pillowcase

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 cm larger on every edge, so its width and its length each grow by 2 cm.

A worked example: Pillowcase, 50 × 60 cm · 20 × 26 in

Fabric width: 150 cm
Seam allowance per edge: 1 cm
Usable fabric width: 150 cm

Front × 1 — Width: 50 cm + 2 × 1 cm = 52 cm · Length: 60 cm + 2 × 1 cm = 62 cm
Back × 1 — Width: 50 cm + 2 × 1 cm = 52 cm · Length: 75 cm + 2 × 1 cm = 77 cm

Where each piece sits on the fabric

Back: 52 cm × 77 cm — x 0 cm · y 0 cm
Front: 52 cm × 62 cm — x 52 cm · y 0 cm

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

Required: 77 cm · 0.77 m · 0.84 yd
Unused fabric area (%): 37.4

A worked example: Pillowcase, 50 × 60 cm · 20 × 26 in (Inches)

Fabric width: 44 in
Seam allowance per edge: 0.5 in
Usable fabric width: 44 in

Front × 1 — Width: 20 in + 2 × 0.5 in = 21 in · Length: 26 in + 2 × 0.5 in = 27 in
Back × 1 — Width: 20 in + 2 × 0.5 in = 21 in · Length: 32 in + 2 × 0.5 in = 33 in

Required: 33 in · 0.84 m · 0.92 yd

Length needed for each template size and fabric width

50 × 60 cm · 20 × 26 in: 110 cm → 77 cm · 140 cm → 77 cm · 150 cm → 77 cm
50 × 70 cm · 20 × 30 in: 110 cm → 87 cm · 140 cm → 87 cm · 150 cm → 87 cm
65 × 65 cm · 20 × 36 in: 110 cm → 149 cm · 140 cm → 82 cm · 150 cm → 82 cm

50 × 60 cm · 20 × 26 in: 44 in → 33 in · 54 in → 33 in · 60 in → 33 in
50 × 70 cm · 20 × 30 in: 44 in → 37 in · 54 in → 37 in · 60 in → 37 in
65 × 65 cm · 20 × 36 in: 44 in → 43 in · 54 in → 43 in · 60 in → 43 in

Template sizes and pieces

Measurements do not include seam allowance. The calculator adds it to each edge.
