Fabric yardage and repeat planner

Estimate roll length for rectangular fabric pieces with seam allowance, straight repeats, grain and nap restrictions.

Dimension units

Changing units reinterprets the entered numbers.

Full roll width

Total unusable selvage

Combined amount removed across both edges.

Seam allowance on each edge

Straight repeat and roll allowances

Horizontal repeat

Enter 0 for no repeat on this axis.

Vertical repeat

Reserves a whole repeat multiple for every row.

Total end allowance

Permit 90° rotation when piece restrictions allow it

Grain or directional nap locks the entered orientation. No 180° reversal is considered.

Up to 30 piece types and 200 cut pieces. Rectangles and straight repeats only.

Suggested roll length

0.7m

Length in yards: 0.7655 yd
Length in chosen units: 70 cm
Usable roll width: 140 cm
Cut pieces: 2
Actual cut area: 6000 cm²
Repeat-reserved slot area: 7200 cm²
Unused / reserved area: 3800 cm²

Slots align to a common repeat grid and reserve extra fabric. This conservative model does not match plaid seams, specific motifs or half-drop repeats.

140 × 70 cm. Dimensions and coordinates use the chosen units.

Light blue is the reserved repeat slot. Darker blue is the cut rectangle including seam allowances. The map uses usable width, with end allowance after the last row.

Why area alone does not determine yardage

A piece can have a small area and still be too wide for the roll. This planner adds seam allowances first, rounds repeat reservations up on each axis, and compares three deterministic shelf orders.

Two 60 × 50 cm pieces fit in one 50 cm row on a 140 cm usable roll. With 20 cm horizontal and 30 cm vertical repeats, they reserve 60 × 60 cm slots and need a 60 cm row. A 10 cm end allowance brings the estimate to 70 cm. Grain and nap restrictions can increase the length.
