Before you buy

Use this as a planning estimate.

Actual quantities vary with product coverage, cuts, surface conditions, layout, and local supplier measurements.

Pattern repeats can consume more material than a plain design.
Use the manufacturer coverage figure rather than the roll's total printed area.
