How to Use the Border Calculator

Enter your finished quilt dimensions (before adding borders), select 1–5 borders, then enter each border's finished width. The calculator uses 40" usable fabric width by default — update this if your fabric is wider.

The calculator adds 0.5" to each finished border width for seam allowances and calculates total linear inches needed per border. Strips are assumed to be cut cross-grain (across the width of fabric).

Each border's yardage is shown separately since borders are often different fabrics. The total at the bottom combines all borders — useful when planning a same-fabric or scrappy border set.
