About This Calculator
The Paint Area Calculator helps contractors and quantity surveyors estimate paint and primer requirements for interior and exterior surfaces across UAE and Gulf construction projects. Calculate wall areas, deduct openings, determine coverage per gallon/liter, and account for multiple coats. Essential for fit-out pricing and material procurement planning.
When to Use This Calculator
- Estimating paint quantities for tender submissions
- Planning material procurement for fit-out projects
- Calculating costs for residential and commercial painting
- Comparing paint options based on coverage and price
- Verifying subcontractor material claims
How to Use This Calculator
Enter Wall Dimensions
Input wall heights and lengths, or total wall area if known.

Typical Scenarios in UAE & Gulf Projects
Finishing contractor estimates paint for a 4-bedroom villa (380m² wall area after openings). Using Jotun Majestic Silk at 12m²/L coverage, 2 coats required: 63.3L paint + 15L primer for new plaster. Calculator adds 10% wastage = 70L paint, 17L primer for procurement.
Facilities manager calculates repaint requirements for 2,500m² office. Existing painted surfaces need 1 coat only at 14m²/L coverage. Calculator determines 180L paint, no primer needed, with 5% wastage factor for touch-ups.
