⬜Drywall Calculator PRO
Multi-room estimator with sheet types, finish levels, compound coats, corner bead, vapor barrier, and insulation.
Dimension Diagram — first room, updates as you type
Wall area comes from the perimeter × ceiling height, minus door and window openings. Ceiling adds length × width.

⚠️ Pre-Export Checklist
- Room dimensions verified on-site
- All openings accounted for (doors, windows, pass-throughs)
- Ceiling height confirmed (standard 8ft or custom)
- Fire-rated drywall needed? (check local code for garages/between units)
- Moisture-resistant board for bathrooms/basements/kitchens
- Vapor barrier required by code in your climate zone?
- Corner bead type confirmed (inside/outside/bullnose)
- Screw type matches stud material (coarse for wood, fine for metal)
How to Estimate Drywall for a Room
Show formulas, finish levels, and worked examples ▼
Formulas
Wall Area= Perimeter × Ceiling Height − Openings
Ceiling Area= Room Length × Room Width
Total Area= Wall Area + Ceiling Area
Sheets Needed= Total Area ÷ Sheet Area (32/36/48 sq ft) × (1 + waste%)
Screws= Total Area ÷ (spacing/12) × stud_count — typically 1 screw per 12" o.c. on each stud
Joint Compound= Total Area × coat_factor ÷ coverage_per_box
Tape= Total Area × tape_factor ÷ coverage_per_roll
Finish Levels (Gypsum Association GA-214)
- Level 0: No finishing — temporary or non-visible areas
- Level 1: Tape embedded in compound, no further coating — attic/Plenum spaces
- Level 2: One coat over tape — utilitarian areas (garage, warehouse)
- Level 3: Two coats over tape — areas to receive heavy texture or tile
- Level 4: Three coats over tape — standard residential walls under flat paint
- Level 5: Skim coat over Level 4 — critical lighting areas, gloss paint, or dark colors
Worked Example
12 ft × 10 ft room, 8 ft ceiling, 2 openings (21 sq ft each), Level 4 finish:
- Wall perimeter: (12 + 10) × 2 = 44 lin ft
- Wall area: 44 × 8 − 42 = 310 sq ft
- Ceiling area: 12 × 10 = 120 sq ft
- Total area: 310 + 120 = 430 sq ft
- Sheets (4×8): 430 ÷ 32 × 1.10 = 15 sheets
- Screws (12" o.c.): 430 ÷ 12 × 4 studs ≈ 516 screws
- Compound (Level 4, 3 coats): 430 × 1.5 ÷ 300 = 3 boxes
- Tape: 430 × 0.8 ÷ 400 = 1 roll
Sheet Types Guide
- 1/2" Standard: Most common for walls in residential construction
- 5/8" Fire Code (Type X): Required in garages, between dwelling units, and for 1-hour fire ratings
- Moisture Resistant (Green Board): Use in bathrooms, kitchens, laundry rooms, and basements
- Soundproof (QuietRock): Reduces sound transmission by up to 90% — ideal for home theaters, studios, shared walls
Common Mistakes to Avoid
- Forgetting to subtract door and window openings
- Not accounting for ceiling — walls only estimate
- Under-ordering compound — Level 4/5 requires significantly more
- Buying exact number without waste — always add 10%
- Using wrong screw type — coarse for wood, fine for metal studs
- Skip vapor barrier in cold climates — moisture leads to mold

Estimar materiales de yeso solía significar suposiciones y recortes sobrantes. Nuestra calculadora elimina el desperdicio calculando cantidades exactas de láminas, compound, cinta y tornillos. Ingrese las dimensiones de la habitación y seleccione el tamaño de lámina estándar (4x8, 4x9 o 4x12).
Ya sea que esté terminando un sótano con paredes de 8 pies, tabicando un garaje con techos de 9 pies, o colgando yeso en una sala con paredes de 12 pies, las cantidades precisas evitan viajes costosos a la tienda. Un dormitorio típico de 12x14 pies necesita aproximadamente 10 láminas de yeso de 4x8.
La cobertura del compound depende del nivel de acabado. Nivel 4 requiere aproximadamente 0.054 galones por pie cuadrado. Nivel 5 agrega una capa completa de cavity.

📐 Fórmulas de Yeso y Cobertura
Área de placa: Área = Longitud × Altura. Láminas: Láminas = Área Total / Área de Lámina. Compound: Nivel 4 requiere 4.3 lbs por 100 pies². Cinta: Cada rollo cubre 75 pies de juntas. Tornillos: Paredes 12 pulgadas, techos 8 pulgadas.
⚠️ Errores Comunes en Instalación de Yeso
No restar aberturas
✓ Siempre reste ventanas y puertas.
Solo comprar compound de empapelado
✓ El empapelado usa solo 30% del total.
Longitud incorrecta de tornillo
✓ Use 1-5/8 pulgadas para yeso de 1/2 pulgada.
Ignorar espaciado de techo
✓ Techos necesitan 8 pulgadas.
No considerar orientación
✓ Horizontal = menos juntas.
Subestimar compound Nivel 5
✓ Nivel 5 necesita 33% más.
Redondear hacia abajo
✓ 16.3 significa pedir 17.
