How this service works
Drywall sheets for a room's walls and ceiling (4x8, 4x10 or 4x12), with waste, screw count and approximate weight.
Output
Returns total sheet count, wall square footage, ceiling square footage, openings square footage (doors/windows deducted), total board area, sheet area, applied waste percentage, approximate screw count, approximate weight in pounds, and a plain-language summary. Also echoes back the sheet size and thickness used.
Example use cases
Bedroom drywall material takeoff
“I'm drywalling a 12x14 bedroom with 8-foot ceilings — it has 1 door and 2 windows. Can you tell me how many 4x8 half-inch sheets I need, including 10% waste, plus how many screws and what the total weight will be?”
Basement finishing material estimate
“Help me figure out the drywall for a 20 by 24 foot basement with 7.5 ft ceilings and no windows or doors, using 4x10 sheets and 15% waste — walls and ceiling both.”
Contractor quote for a large great room
“I need a drywall estimate for a 22 ft by 18 ft great room with 10-foot ceilings, 3 doors and 4 windows. Use 5/8-inch 4x12 sheets with 12% waste and include the ceiling — what's the sheet count, screws, and weight?”

Endpoint
GEThttps://construction-calc.x402tookit.com/drywall-calc?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, reliable material estimate for drywall specifically — including waste factor, screw count, and weight — for rectangular rooms. It handles both walls and ceiling in one call, and deducts door and window openings automatically. Prefer it over manual calculation or generic construction tools when you need structured numeric output suitable for purchase orders or contractor quotes.
Side effects
- Missing required parameters (lengthFt, widthFt, heightFt) returns an error
- Invalid sheetSize value (not 4x8, 4x10, or 4x12) may return an error or default
- Negative or zero dimensions produce nonsensical results
- Too many doors/windows relative to wall area may produce zero or negative net area
- Payment failure (HTTP 402) if USDC payment is not submitted correctly
