Drywall Screws Calculator
Calculate the exact number of drywall screws needed for your project. Determine screw spacing, quantities, and costs based on wall dimensions, drywall panel size, and installation requirements.
Step 1: Wall & Drywall Specifications
Standard Drywall Panel Sizes
Standard drywall panels are 120×240 cm (4×8 ft). For ceilings, consider 120×260 cm or 120×300 cm panels to reduce joints. Always account for 10% waste when calculating materials.
Step 2: Screw Specifications
25 cm
38 mm
40 cm
Recommended Screw Spacing
For walls: 25-30 cm on studs, 15-20 cm on edges. For ceilings: 15-20 cm on all studs. Use 38mm screws for single-layer, 50mm for double-layer drywall.
