Whole quantities are rounded up.
How it's calculated
Panels = round up(span ÷ maximum panel length). Internal joints = panels − 1. Clear panel length = (span − joint widths) ÷ panels.
Calculations use consistent units for your selected measurements. Whole purchase quantities are rounded up.
What this estimate includes
Maximum spacing is user-specified. This geometric layout does not design movement or concrete control joints.
Quantity and arithmetic estimates only. Use project specifications for installation and design requirements.
