Frequently asked questions
What does this calculator calculate?
Estimate drywall tape rolls from wallboard area, a project tape-rate assumption, roll length, and allowance.
How is the result calculated?
Rolls = ceil[Area × Tape Feet per 1,000 sq ft ÷ 1,000 × (1 + Allowance %) ÷ Roll Length].
Can I use the result for an important decision?
Use the result as a calculation aid and verify the inputs, assumptions, and applicable professional or regulatory requirements before relying on it for an important decision.
Does CalculateMeasure store the values I enter?
The calculator performs its arithmetic in your browser. The calculator itself does not need to send your entered values to a server to produce the result.
