What Is a Fabric Calculator?
A fabric calculator estimates the amount of fabric needed for a sewing project based on the dimensions of your cut pieces, the fabric width, and allowances for seams, pattern matching, and waste. It accounts for how efficiently pieces can be cut from the fabric bolt and helps prevent buying too little or too much fabric.
