How to use it
- Enter wall length in feet.
- Enter wall height in feet.
- Click Calculate.
- Read the total square‑foot formwork area.
What it does – The Concrete Formwork Calculator takes the length and height you input and instantly tells you how many square feet of formwork you’ll need for both faces of the wall. No top or bottom edging is counted, so the result matches what you actually order from the supplier. Why it matters – Ordering the right amount saves money, reduces waste, and keeps the schedule on track. How to read it – The number shown is the total area (sq ft) covering the front and back of the wall; multiply by your concrete‑panel cost to estimate material expense. Use the result to size your plywood, steel studs, and labor crew. It also helps you fill out permit applications that require total formwork area.
Pro tips
- Add a 10% waste allowance for cuts and damage.
- Round up to the nearest whole sheet of plywood when ordering.
- Verify wall dimensions on site before entering them.
- Remember the calculator only covers faces; include edge formwork separately if needed.

Case study
Mike, a small‑contractor, was manually adding lengths and often over‑ordered plywood. After using the calculator, he entered a 40‑ft wall at 9‑ft height, got 720 sq ft instantly, added a 10% waste factor, and ordered exactly 800 sq ft. He saved $350 on material and finished two days early.
