Why this result?
A calculator should show its seams.
Every Yard & Loop plan separates the base measurement, material assumptions, safety buffer, and purchasing round-up. You can see where the extra came from before it becomes an offcut.
- Change the buffer instead of accepting a mystery margin.
- Compare layouts when fabric direction allows it.
- Print a plan that reconstructs the result.

Useful thinking between the measurements.

Vertical or horizontal? Piece a quilt backing with less waste
The lowest-yardage layout is not always the best layout. Compare seam direction, print direction, handling, and the offcuts you will actually reuse.
