Lighting Layout Calculator (# of Pot Lights)

Calculate exact number of pot lights, grid layout (rows × columns), and ceiling spacing to achieve smooth, shadow-free illumination.

1. Room Dimensions & Use

Room Length (Feet)

Room Width (Feet)

Ceiling Height (Feet)

Room Type / Target Brightness

2. Grid Layout Recommendation

Ceiling Grid Spacing

RECOMMENDED POT LIGHT COUNT

8 Pot Lights

GRID PATTERN

4 Rows × 2 Columns

SPACING BETWEEN LIGHTS / WALL

4.0' from wall / 8.0' apart

Optimal Layout: 4" or 6" LED slim pot lights spaced evenly prevent harsh shadows on countertops and floors.

Pot Light Layout Rules of Thumb

Distance between pot lights should equal approximately half the ceiling height (e.g., 4 ft apart on an 8 ft ceiling).
Distance from wall to first light should be half the distance between lights to prevent wall shadows.
Always select IC-rated (Insulation Contact) ultra-slim LED pot lights for insulated ceilings.

Lighting a room properly

Pot light spacing rule of thumb

Based on ceiling height; keep it even and off the walls.

Ceiling height	Spacing between lights	Distance from wall
8 ft	4 ft	2 ft
9 ft	4.5 ft	2.25 ft
10 ft	5 ft	2.5 ft

Rule: spacing ≈ ceiling height ÷ 2; wall distance ≈ spacing ÷ 2. Dimmers make the layout forgiving.
