Drywall & Metal Stud Framing Calculator per m² (Walls & Ceilings)

Calculate the exact number of drywall sheets (gypsum boards), metal studs, tracks, joint compound, tape and screws per square meter.

Drywall System Type

Total Wall / Ceiling Area (m²)

Stud Spacing (Centers)

Board Dimensions (1.20m wide)

Drywall Boards (+7% waste)22 Boards

Vertical Studs (linear m)83 m lineales

Horizontal Tracks (linear m)27 m lineales

Joint Compound & Tape29 kg / 99 m

Material Consumption Ratios for Drywall Framing Systems

Construction Standard (ASTM C840 / EN 520): Calculation includes a 7% waste factor on gypsum boards and standard stud centers at 400 mm (16") or 600 mm (24").

Total Board Area (m²) = Wall Area × Total Board Layers × 1.07 (7% waste)
Linear Meters of Studs = Wall Area × (2.75 m/m² at 400mm centers | 2.10 m/m² at 600mm centers)

Frequently Asked Technical Questions (FAQ)

How many drywall sheets and metal studs are needed per m²?

A single-layer partition wall (1 board per side) requires 2.14 m² of board per m² of wall (including 7% waste), 0.90m of U-track and 2.10m to 2.75m of vertical C-studs.

When should studs be spaced at 400 mm (16") instead of 600 mm (24")?

Use 400 mm stud spacing for walls supporting ceramic tile, heavy wall-mounted cabinets or high acoustic/impact loads.
