How the calculation works
Effective step = sheet dimension − overlap. Count full sheets needed in each direction, test the rotated orientation and choose the smaller full-sheet grid.
A worked example
A 10 × 10 ft area needs two 5 × 10 ft sheets with no overlap. With a 6 in overlap, that two-sheet arrangement no longer spans the full width.
What to check before using the result
- Actual offcut reuse can reduce a full-grid purchase.
- The project designer or supplier must specify the required mesh and overlap.
