Napkin set

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: Napkin set, 6 × 45 cm · 6 × 18 in

Fabric width: 140 cm
Seam allowance per edge: 1 cm
Usable fabric width: 140 cm

Napkin × 6 — Width: 45 cm + 2 × 1 cm = 47 cm · Length: 45 cm + 2 × 1 cm = 47 cm

Where each piece sits on the fabric

Napkin 1: 47 cm × 47 cm — x 0 cm · y 0 cm
Napkin 2: 47 cm × 47 cm — x 47 cm · y 0 cm
Napkin 3: 47 cm × 47 cm — x 0 cm · y 47 cm
Napkin 4: 47 cm × 47 cm — x 47 cm · y 47 cm
Napkin 5: 47 cm × 47 cm — x 0 cm · y 94 cm
Napkin 6: 47 cm × 47 cm — x 47 cm · y 94 cm

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

Required: 141 cm · 1.41 m · 1.54 yd
Unused fabric area (%): 32.9

A worked example: Napkin set, 6 × 45 cm · 6 × 18 in (Inches)

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

Napkin × 6 — Width: 18 in + 2 × 0.5 in = 19 in · Length: 18 in + 2 × 0.5 in = 19 in

Required: 57 in · 1.45 m · 1.58 yd

Length needed for each template size and fabric width

4 × 45 cm · 4 × 18 in: 110 cm → 94 cm · 140 cm → 94 cm · 150 cm → 94 cm
6 × 45 cm · 6 × 18 in: 110 cm → 141 cm · 140 cm → 141 cm · 150 cm → 94 cm
8 × 45 cm · 8 × 18 in: 110 cm → 188 cm · 140 cm → 188 cm · 150 cm → 141 cm

4 × 45 cm · 4 × 18 in: 44 in → 38 in · 54 in → 38 in · 60 in → 38 in
6 × 45 cm · 6 × 18 in: 44 in → 57 in · 54 in → 57 in · 60 in → 38 in
8 × 45 cm · 8 × 18 in: 44 in → 76 in · 54 in → 76 in · 60 in → 57 in

Template sizes and pieces

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