Estimate drywall sheet count for walls from room perimeter, wall height, and the usable coverage of each sheet.
Interior wall planning where you know the room perimeter and the sheet size you intend to purchase.
A 56 ft perimeter with 8 ft walls and 32 ft² sheets demonstrates the relationship between wall area and sheet count.
Default example result: 16 sheets with 10% allowance.
The calculator uses the displayed formula, applies your waste allowance, and rounds purchase quantities up. Review the assumptions before ordering and confirm product coverage with your supplier.
Formula used: perimeter × height × (1 + waste) ÷ sheet coverage
The default calculation is for wall area. Estimate ceiling area separately or combine it with a suitable project worksheet.
Yes. The waste field helps account for cuts and damage, but complex layouts may need a larger allowance.
This calculator is for preliminary planning and purchasing estimates. It does not replace professional design, local building codes, site conditions, safety checks, or supplier guidance.
