Compare fabric widths

Change the usable fabric width and compare the length needed for the same pieces.

Your measurements

Decimals and fractions such as 1.5, 1½ or 1 1/2 are accepted. Do not use thousands separators.

For cut-on-fold pieces, enter the half-pattern width. The folded edge receives no seam allowance.

How the calculation works

Keep the pieces and seam allowance unchanged while comparing fabric widths. A wider fabric can allow another piece in the same row, so the required length changes in steps rather than as a simple width ratio.

The comparison includes 1100, 1400 and 1500 mm widths with the same grain and folding settings. A width that cannot accommodate every piece is marked accordingly. Check the usable width after removing selvages before buying.
