Pro Tips for Stair Carpet Area
- Area per stair should include both the tread (horizontal step surface) and riser (vertical face) if both will be carpeted, not just the tread.
- Add extra material for waste and pattern matching, especially if using a patterned or directional carpet.
Common Stair Carpet Area Mistakes to Avoid
- Calculating area per stair based on tread surface alone when the riser will also be carpeted, which would understate total material needed.
