Questions quilters ask
How do I calculate fabric for a quilt border?
For a simple border, cut two side strips the quilt height and two top-and-bottom strips the quilt width plus twice the border width. This calculator totals those strips and rounds up the yardage.
Does this quilt border calculator handle mitered corners?
No. It is deliberately limited to a single border with butted corners, so the cutting plan stays clear and the result is easy to check before cutting.
