A: It's recommended to order 10-20% extra carpet to account for pattern matching, seams, and potential mistakes during installation.

Q3: Does this work for irregularly shaped rooms?
A: No, this calculator is for rectangular areas only. For irregular shapes, divide the space into rectangles, calculate each separately, then sum the results.

Q4: How accurate should my measurements be?
A: For carpet installation, measurements should be precise to within 1-2 inches for best results.

Q5: What if my room isn't a perfect rectangle?
