Pro Tips
For irregular rooms, divide the space into several rectangles, calculate each separately, and add them together.
Most flooring experts suggest adding 10% to your final area count to account for waste and cuts.
When measuring for paint, don't forget to subtract the square footage of windows and doors from your total wall area.
