Wall Washing vs Grazing
Two visually different effects from similar fixtures. Washing flattens, grazing reveals texture. How to choose between them.
Same Family, Opposite Effects
Wall washing and wall grazing both light vertical surfaces. The difference is the angle and offset, which produce completely different results.
Comparison
| Quality | Wall Wash | Grazing |
|---|---|---|
| Fixture offset from wall | 0.6–1.2m | 0.1–0.3m |
| Beam direction | Down at 30°–60° | Down at 10°–15° |
| Effect | Even, flat glow | Strong shadows, reveals texture |
| Best for | Smooth plaster, paint, glass | Stone, brick, textured concrete |
| Aesthetic | Calm, uniform | Dramatic, sculptural |
When to Use Which
- Washing for clean modern facades and contemporary interiors
- Grazing for heritage stone, brick walls and textured features
- Never use washing on textured walls, the texture disappears
- Never use grazing on smooth walls, you see hotspots without payoff
Common Mistakes
- Mounting wash fixtures too close, becomes grazing
- Mounting graze fixtures too far, becomes wash
- Mixing the two on the same wall
Professional Recommendation
Choose the technique that matches the material. The fixture matters less than the geometry of how it is mounted.
