Frequently Asked Questions
What sheet area should I enter?
32 sq ft for 4 × 8 sheets, 40 for 4 × 10, and 48 for 4 × 12. Larger sheets mean fewer seams to tape but are heavier to hang.
How does the waste percent work?
The area is divided by the sheet size and increased by the waste percent, then rounded up. 640 sq ft with 32 sq ft sheets and 10% waste needs 22 sheets.
Should I subtract doors and windows?
Many installers do not, since offcuts from openings are hard to reuse. Subtracting large openings like garage doors is reasonable; small windows can usually be left in.
