How it is calculated
Net walls = Internal perimeter (m) × Height (m) − Doors and windows (m²)
Paint needed = ( Net walls + Area (m²) ) × Paint coats / Coverage per coat (m²/l) × (1 + Material allowance (%) /100)
Floor with allowance = Area (m²) × (1 + Material allowance (%) /100)
What to check
Paint covers walls and ceiling; tiles cover the floor only. Packs are rounded up. Check manufacturer coverage. Excludes preparation, adhesive, grout and labour.

Frequently asked questions
Is this a final quote?
No. Results depend on your inputs and the stated scope. A professional must check the property, measurements and conditions before quoting.
Can I use measurements from my plan?
Renovation, radiator, cooling and materials calculators can use internal plan measurements. Enter built area and the thermal envelope separately. You can save scenarios in your project.
