Quilt Border Guide
A border frames your quilt, squares up uneven edges, and can become a design feature in its own right. Planning the yardage before you cut keeps the border flat and the corners clean.
How to Calculate Border Yardage
Measure the quilt edge the border will cover, multiply by the number of sides, add seam allowances plus a little extra for corners, then divide by your usable fabric width (about 40 to 42 inches) to get the strip count. Multiply strips by border width and divide by 36 for yards.
Measure Through the Center
Measure through the center of the quilt top because edges can stretch during piecing. If the quilt is slightly skewed, use the longest measurement so the border lies flat instead of rippling.
Mitered vs. Butted Corners
Butted (straight) corners are quick and strong. Mitered corners look crisp on straight-grained borders and avoid a bulky seam, but they need a few extra inches per corner, so plan yardage accordingly.
Border Yardage by Width
| Quilt | Border | Border length needed |
|---|---|---|
| Lap 50×60 | 3" | ~226" |
| Twin 70×90 | 4" | ~328" |
| Queen 90×108 | 5" | ~416" |
Frequently Asked Questions
How do I calculate border yardage?
Measure the quilt edge the border will cover, multiply by the number of sides, add seam allowances and a little extra for corners, then divide by your usable fabric width to get strip count. Multiply strips by border width and divide by 36 for yards.
Should I miter quilt border corners?
Mitered corners look crisp on straight-grained borders and avoid a bulky seam at the corner. They take a little more length, so add a few inches per corner when planning yardage.
How wide should a quilt border be?
A common border is 2 to 6 inches wide. A narrow 2 to 3 inch border frames a quilt simply, while a wide 6 inch or larger border can become a design feature with pieced blocks.
Should I measure through the center or the edge?
Measure through the center of the quilt top because edges can stretch. Use the longest measurement if the quilt is slightly skewed so the border lies flat.
