About this calculator

In the UK and most of Europe plasterboard comes in 1200×2400 mm or 1200×2500 mm sheets (sometimes 1200×3000 mm). Divide the wall area by the sheet area and round up. Add 10% for waste — cuts around sockets, windows and corners always create offcuts. A 12.5 mm board is standard for walls; 15 mm is required for fire-rated walls (UK Approved Document B).
