Strip Quilt Calculator
Zero Waste & No Sign-up: Calculate how many fabric strips and yards you need for a strip quilt. Enter quilt dimensions and strip width to get accurate yardage requirements.
How to Use the Strip Quilt Calculator
Enter the quilt dimensions, your strip cut width, and whether the strips run horizontally or vertically. Because each seam consumes a quarter inch on both sides, a strip finishes half an inch narrower than it is cut — a 2-1/2 inch Jelly Roll strip covers just 2 inches of the quilt.
The number of strips is the quilt dimension perpendicular to the strips divided by the finished strip width, rounded up. Strips are cut 4 inches longer than the quilt dimension they run along, an ease margin that lets you square the top after the long seams inevitably wander a little.
For yardage, the tool works out how many strips one width-of-fabric cut provides — 44 inches divided by the cut width, rounded down — and converts the resulting fabric length to yards, rounded up to the next eighth. A 60 x 80 inch quilt in horizontal 2-1/2 inch strips needs 40 strips, each cut 64 inches long.
Frequently Asked Questions
What width should I cut strips for a strip quilt?
Common strip widths are 2.5 inches (Jelly Roll size), 3 inches, or 3.5 inches. Narrower strips create a delicate look while wider strips work up quickly. The finished strip width is always 0.5 inch less than the cut width.
How do I join strips end to end?
Sew strips at a 45-degree diagonal angle to distribute the seam bulk and create a smooth join. Press the seam open for the flattest result before continuing to piece.
Can I use a strip quilt design for any size?
Yes. Strip quilts scale easily from baby to king sizes. Simply adjust the strip width and length, and the calculator will update the required yardage and strip count automatically.
