This quilt sashing calculator helps estimate the total length of sashing needed for a quilt top. Enter the quilt width, quilt length, and the width of the sashing strips to determine the total sashing required.
How to use calculator
Enter the finished width and length of your quilt top in inches. Then enter the width of the sashing strips you plan to use. The calculator estimates the total length of sashing needed around the quilt layout.
Explanation
Sashing is the fabric placed between quilt blocks to separate them and add visual structure to the quilt design. Estimating the total length of sashing helps quilters determine how much fabric to cut before assembling the quilt top.
The calculator estimates the quilt perimeter to determine the total length required.
Example math
If a quilt measures 60 × 72 inches, the perimeter is calculated as:
(60 × 2) + (72 × 2)
Which equals:
264 inches
This is the estimated total length of sashing needed.
