Measure the length and the width of a room with your laser meter, type the two readings and read the area in square metres and square feet. Add more rooms to get a total for a flat or a floor.

Measuring a room for area
- Shoot from the same wall at the same height; the meter measures from its reference edge (usually the back), so keep that edge against the wall.
- For an L-shaped room, split it into two rectangles and add both.
- Walls are rarely perfectly parallel: shoot the length twice (near each end) and use the average, or the larger value when ordering material.
For the error band of the result, see the accuracy explainer.
