How to Calculate Drywall for a Room

Esta calculadora de drywall estima la cantidad de drywall sheets, joint tape rolls, joint compound buckets, screws, and corner bead pieces needed for walls and ceilings. Ingrese las dimensiones de la habitacion en pies y pulgadas with fraction precision, select your sheet size (4×8, 4×10, or 4×12), and set the waste allowance from 5% to 20%.

Formulas Used

Net area = gross wall/ceiling area − door − window .
Sheets = ceil(net area × (1 + waste%) ÷ sheet area).
Joint tape = perimeter joints ÷ 500 ft per roll.
Joint compound = net area ÷ 100 ft² por capa × numero de capas.
Tornillos = 1 per ft² of drywall installed.

Frequently Asked Questions

What size drywall should I use? 4×8 is standard and easiest to handle. 4×12 sheets reduce joints but are heavier. Use ½" for most walls and ceilings; ⅝" for fire-rated assemblies or soundproofing.

How much waste should I plan for? 10% is typical for rectangular rooms. Use 15-20% for rooms with many corners, angles, or cutouts. Minimize waste by planning sheet layout before cutting.
