Lighting plan for 10x12 and 12x12 rooms

How many downlights does a room need, and where should they go? Here is a simple plan for two common room sizes.

10 x 12 foot room: 6 lights

Arrange the lights in 3 rows of 2. Place the rows about 4 feet apart and the two lights in each row about 5 feet apart. Keep the outer lights about 2 feet from the walls.

10 x 12 room: 2 lights across, 3 along

A pack of 6 covers this room.

12 x 12 foot room: 9 lights

Arrange the lights in a 3 by 3 grid. Space them about 4 feet apart and keep the outer lights about 2 feet from the walls.

12 x 12 room: 3 lights across, 3 along

A pack of 10 covers this room, with one light spare.

This is a guide, not a fixed rule. Add a light or two if your ceiling is high, your walls are dark, or the room is used for work or study. Use fewer if you like a softer look.

Tips for a better result

  • Use one colour of light in the whole room. See our colour guide.
  • Check your hole size first. See our hole size guide.
  • Packs cost less per piece than single lights.
