Floor area calculator questions
- How do I calculate the square metres of a room?
- Multiply the room's length by its width. For example, a room measuring 5 metres by 4 metres has an area of 20 m².
- Can I calculate multiple rooms?
- Yes. Add each room separately and the calculator will combine all valid room areas into one total.
- How do I measure an L-shaped room?
- Divide the room into two or more rectangles. Measure each section separately and add every section to the calculator.
- Should I include areas without wooden flooring?
- Only include the areas containing the wooden floor that you want Thomasparketpro to inspect or treat.
- Does the calculator provide a final renovation price?
- No. It calculates an estimated floor area only. The final quotation depends on the floor's condition, selected treatment, required repairs, accessibility, and other project details.
