Envelope Pillow Front and Back Fabric Cut calculator.
Keep one front and two supplied overlapping back panels per pillow as complete rectangles in a stock allocation.

Formula and assumptions
How this calculation works.
Front = (width + 2 × hem)(height + 2 × hem); each back = (width + 2 × hem)(height/2 + overlap/2 + 2 × hem). Uses an explicitly supplied equal-back-panel pattern; no shrinkage or sewing method is selected.
