How the estimate works
- Plates = slab area ÷ area of one plate, plus your extra percentage, rounded up.
- Props = (length ÷ spacing + 1) × (width ÷ spacing + 1), rounded up, for a simple grid.
It doesn't include beam sides and bottoms, slab edge shuttering, runners, spans or clamps. Read how many shuttering plates do I need for the full method, and the prop spacing guide before choosing a spacing.
This is a planning estimate only. Final quantities and prop spacing should be confirmed against your drawings by a qualified engineer. We're happy to check your numbers for free.
