All tools / Material yield

Material yield.

How many parts fit on a sheet. Enter sheet size, part size, spacing, and edge trim, and the tool compares both part orientations and reports the better layout, waste percentage, and sheets needed for your run.

Inputs.

All dimensions in the same unit. Spacing is the gap between neighboring parts; trim is removed from each sheet edge.

Sheet width

Sheet height

Part width

Part height

Spacing between parts

Edge trim per side

Orientation

Parts needed for the run

Grain locked keeps the part width running along the sheet width, which is what you want when grain direction, flute direction, or print orientation can't rotate. Best of both tries the part rotated 90 degrees and reports whichever fits more.

Results.

Yield assumes a straight grid layout. Nested or staggered layouts can beat these numbers for irregular shapes.

Usable area is the sheet minus edge trim on all four sides. Parts-per-row math: floor((usable + gap) / (part + gap)) in each direction, so spacing counts between parts but not at the edges.

Disclaimer: These tools were built at my desk to keep the answers I need in one place. I’m sharing them in the hope that they make your design process a little easier too. The math is checked against published standards and real-world experience, but specs change and materials vary. If you spot anything that seems off, please email me at donna@donnakadell.design and I’ll take a look.

Enjoy.
