Room Quantity Takeoff Calculator
Build a fast room-by-room quantity takeoff from basic dimensions. Enter length, width, height and opening area to calculate the most common surface and volume quantities used in early estimating and project checks.
How to use it in practice
For a 5 m × 4 m room that is 2.8 m high, the tool calculates 20 m² of floor, 18 m of perimeter and 50.4 m² of gross wall area before subtracting the entered opening area.

Common questions
What is net wall area?
Net wall area is the calculated gross wall surface minus the opening area entered for doors, windows or other deductions.
Can I calculate opening deductions separately?
Yes. The takeoff workspace includes a small door/window deduction builder and can copy the opening total into a room.
Can I export the results?
Yes. Room takeoffs can be exported as CSV for use in spreadsheets or other estimating workflows.
