Last updated: July 2026 | Reading time: 6 minutes
Understanding blackout levels is crucial when choosing curtains or blinds for your Singapore home. Different rooms require different levels of light blocking. This guide explains the various blackout levels and helps you choose the right one.
Blackout Levels Explained
| Level | Light Blocking | Description | Best For |
|---|---|---|---|
| Sheer | 5-20% | Allows most light through, provides privacy | Living rooms, dining areas |
| Light Filtering | 30-50% | Softens light, reduces glare | Kitchens, bathrooms |
| Dimout | 70-90% | Significantly reduces light | TV rooms, home offices |
| Blackout | 95-99% | Blocks nearly all light | Bedrooms, nurseries |
| Full Blackout | 100% | Complete darkness | Home theaters, shift workers |
Choosing the Right Level for Each Room
Master Bedroom: 99-100% Blackout
Singapore's early sunrise (7am year-round) makes blackout curtains essential for quality sleep. Shift workers especially need full blackout to sleep during daylight hours.
Children's Room: 95-100% Blackout
Children need consistent sleep schedules. Blackout curtains help them nap during the day and sleep through early morning light.
Living Room: 50-70% Light Filtering
Living rooms benefit from natural light during the day. Sheer or light-filtering curtains create a bright, welcoming atmosphere while providing privacy.
Kitchen: 30-50% Light Filtering
Kitchens need natural light for cooking. Light-filtering roller blinds reduce glare while maintaining brightness.
Bathroom: 30-50% Privacy
Bathrooms need privacy but not complete darkness. Frosted or light-filtering blinds work best.
