How many parts fit on a sheet?
Enter the sheet and part size to see how many parts fit, how many sheets you need and your yield. Parts are rotated, and parts that fit in the leftover strip are tried too.
Calculated in your browser; the numbers you enter are never sent anywhere.
Optional: for material cost per part.

How is it calculated?
The usable area is the sheet size minus the edge margin on each side. Parts are laid out in a grid with the gap between them.
Then a rotated grid, and a mixed layout with rotated parts added in the leftover strip, are tried; the layout with the most parts wins. On a tie, the straight grid wins because it's easier to cut.
Sheets needed = quantity ÷ parts per sheet, rounded up. Yield = total area of the parts ÷ total area of the sheets used.
The calculation is for rectangular parts and reliably estimates the grid layout you'd do by hand in the shop. For round or freeform shapes, enter the rectangle that encloses the part.
