Enter your room measurements below

With L-shaped rooms, measure by dividing the room into two perfect rectangles. Measure the longest length and multiply it by the longest width of each rectangle and add both values together to get the total meter squared (m2).

Measure the longest length and multiply it by the longest width of the room to get the total meter squared (m2).

This is typical for rooms with a chimney breast, measure the longest length and multiply it by the longest width of the room (up to the dotted line shown above). Do the same for each alcove. Add all the values together to get the total meter squared (m2).
