Frequently asked questions
How do I measure an irregular room?
Split it into simple rectangles, calculate each one, and add the areas. Exclude closets or openings only when the product instructions allow it.
Does this include waste?
No. This reports measured area. Add the waste allowance recommended for the material afterward—often 5% to 10% for flooring.
