Pro Tips for Stair Carpet Area

  1. Area per stair should include both the tread (horizontal step surface) and riser (vertical face) if both will be carpeted, not just the tread.
  2. 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.
