📖 Overview

This calculator provides material takeoff numbers for small renovation and finishing plans.

It includes sheet count mud estimate and tape rolls with configurable waste.

🧪 Example Scenarios

Use these default and higher-pressure example inputs to explore how sensitive this calculator is before using your real numbers.

InputBase CaseHigher Pressure Case
Room Length (ft)1820.7
Room Width (ft)1213.8
Ceiling Height (ft)89.2
Openings Area Deduction (sq ft)2629.9
Waste Factor (%)1012

⚙️ How It Works

Calculates drywall coverage area with openings deduction and waste, then estimates sheets compound weight and tape rolls.

The Formula

Total Area = ((Walls + Ceiling − Openings) × (1 + Waste%))
Room LengthRoom length in feet
Room WidthRoom width in feet
Ceiling HeightWall height in feet
OpeningsDoor and window area not drywalled
Waste %Allowance for cuts breakage and offcuts
💡This calculator is scenario-based. Better input quality leads to better decision quality.

When To Use This

  • Use this tool when you need a fast decision during active planning or execution.
  • Use this before committing money, time, or tradeoffs that are hard to reverse.
  • Use this to compare options using the same assumptions across scenarios.

Edge Cases To Watch

  • Results can be misleading if key inputs are missing, stale, or unrealistic.
  • Very small or very large values may amplify rounding effects and interpretation risk.
  • If assumptions change mid-decision, recalculate before acting.

Practical Tips

💡 Use consistent tape and finish level assumptions across projects.
💡 Complex corners and soffits increase both tape and mud consumption.
💡 Include ceiling only if you are hanging drywall on it.

Frequently Asked Questions

❓ Does this include studs and framing material?

No this takeoff focuses only on drywall sheets compound and tape.

❓ Why can compound usage vary?

Finish level and installer technique can change mud usage significantly.
