What the calculator needs
The calculator starts with the finished length, width, height, and seam allowance you want at the machine.
That turns one set of finished dimensions into a clear cut plan with boxed-corner marks, so you can cut once and sew with confidence.
If you already know the finished size you want, the calculator turns those measurements into cut dimensions you can use at the machine.
Open the calculator or return to the top with the hero after you compare sizes.
