Board and Panel Weight Calculator

1. Pick the material. The density fills in with a typical figure. If you have the board maker's data sheet, type the exact density in.
2. Enter the thickness, height and width, how many you have, and the weight of the handle and anything else fixed to the panel.
3. Say what it is. A hinged door gets a guide to how many hinges it needs. A lift-up flap gets its power factor for choosing the lift mechanism. A sliding door gets the weight to check against the gear.
4. Weigh the whole job by listing every part, to plan lifting, loading and delivery.

The maths

Weight is height × width × thickness × density. With sizes in millimetres and density in kg/m³, that is H × W × T × density ÷ 1,000,000,000. 18 mm MFC at 650 kg/m³ weighs about 11.7 kg per square metre, so a 2000 × 500 mm wardrobe door is about 11.7 kg before the handle.

Typical densities

• Chipboard / MFC: about 650 kg/m³, or 11.7 kg/m² at 18 mm
• MDF: about 750 kg/m³, or 13.5 kg/m² at 18 mm
• Birch plywood: about 680 kg/m³, or 12.2 kg/m² at 18 mm
• Solid oak: about 720 kg/m³, or 14.4 kg/m² at 20 mm
• Glass and mirror: about 2,500 kg/m³, or 15 kg/m² at 6 mm
