Room Lighting Calculator
Calculate the recommended lumens and number of bulbs for any room based on size and room type.
Recommended Lighting
Room lighting is measured in lumens, with requirements varying by room type.
Total Lumens = Room Area (sq ft) × Lumens per sq ft
Recommended lumens per square foot by room type:
- Kitchen: 70-80 lumens/sq ft
- Bathroom: 70-80 lumens/sq ft
- Living room: 40-50 lumens/sq ft (with task lighting)
- Bedroom: 30-40 lumens/sq ft
- Dining room: 30-40 lumens/sq ft
- Home office: 60-70 lumens/sq ft
- Hallway: 20-30 lumens/sq ft
- Garage: 50-60 lumens/sq ft
