The Sailrite Fabric Calculator

Slipcovers

A. Width of Foam (?)
Measure the width (often called depth) of the foam from edge to edge. This calculator only works with square or rectangular-shaped foam.
Decimals!
B. Length of Foam (?)
Measure the length of the foam from edge to edge. This calculator only works with square or rectangular-shaped foam.
Decimals!
C. Thickness of Foam (?)
Measure the thickness of the foam from bottom to top.
Decimals!
C. Vertical Pattern Repeat (if any) (?)
If your cushion has a vertical pattern, this entry is only helpful if the quantity of slipcovers is two or more. Entering the vertical repeat positions, multiple cushion patterns on the running length of the fabric, spaced to accommodate the extra fabric required for the vertical repeat to match the next pattern. NOTE: Sailrite does not cut fabric at a specific vertical repeat pattern when you order it, so you may want to order more fabric than what the calculator indicates, if the vertical repeat pattern is of paramount importance between multiple cushions.
Quantity (?)
Total number of slipcovers needed with the same dimensions.
Integer!
Fabric Width (?)
This is the manufacturer’s usable fabric width (weft) of the fabric you have selected (usually 54”, 60” wide).
Numbers!
Orientation of Slipcover on Running Length of Fabric (?)
Use this to position the slipcover lengthwise or widthwise on the fabric. Often used to orient a pattern, like stripes, a certain direction on the fabric or to keep from seaming sections of fabric together for an extra-long length of slipcovers. Click between the buttons to see the difference in the way the panel is oriented in the “Panel Rendition” below.
