Whats the best way for me to measure my room to order the right quantity of paint?
For floors and ceilings measure left to right and front to back and multiply one figure by the other to get the “square” area. Add 10 percent to that figure for safety. For walls measure the length of each wall to be painted and add the figures together to give you the perimeter of the room. Measure the height of the room and multiply the two figures together to give you the total area. When calculating the total area of a room, bear in mind that you don’t need to include the space taken up by kitchen units, tiling, doors and windows etc.
