Calculators for home decor sewing and quilting. Get the math right for curtain panels and quilt construction before you buy fabric.
Curtain Calculator
Fabric yardage for curtains — by window size, header style, fullness ratio, and panel count.
Quilting Calculators
Backing yardage, binding strips, border fabric, and strip piecing — four tools in one.
Getting curtain yardage right
Curtain fabric requirements depend on more than just the window size. Header style (rod pocket, tab top, pinch pleat, grommet) affects the cut length, and fullness ratio (typically 1.5x to 3x the window width) determines cut width. The Curtain Calculator handles all of these variables.
For quilting, the four calculators cover the most common math: backing yardage (usually 4-8" larger than the quilt top on each side), binding strip count and total length, border fabric, and strip piecing yield.
