Calculator Inputs and Outputs
Inputs
- Drywall area (sq ft) — example: 2400
- Sheet coverage (sq ft) — example: 32
- Average tape per sheet (ft) — example: 12
- Waste allowance (%) — example: 10
- Tape roll length (ft) — example: 250
Results
- Tape rolls
- Estimated tape length (ft)
- Estimated sheets
Formula used
Tape length = estimated sheets × tape per sheet, plus waste.

Formula
Tape length = estimated sheets × tape per sheet, plus waste.
Understanding the Results
The primary answer appears first. Supporting outputs show related quantities, conversions, dates, costs, ratios, or intermediate values. Calculations keep additional precision before display rounding.
Accuracy Tips
- Use measured values and consistent units.
- Review assumptions, waste rates, fees, timing, and efficiency inputs.
- Recalculate after changing any project condition.
