Recessed Lighting Layout: How Many Cans and Where to Put Them

The spacing rule

Divide ceiling height by two for spacing between cans; place the first row half that distance from walls.

Choosing size and lumens

4-inch cans suit most rooms; 6-inch for high ceilings. Aim for 20 lumens per square foot in living areas, 70–80 in kitchens.

Color temperature

2700K–3000K for living spaces, 3500K–4000K for kitchens and workspaces.

Dimming and zones

Put task, ambient and accent lighting on separate dimmers for flexibility.
