Ceiling Light Size Guide

Find your ceiling light size

For flush and semi-flush ceiling lights. Use these guides with the width and height in the product’s Dimensions tab.

Drawn to scale: a flush mount and a semi-flush light, each with 7 ft below.

1. Choose the type

By ceiling height

Flush mounts sit tight to the ceiling. Semi-flush lights hang about 4–8 in below it; anything lower counts as a pendant.

Ceiling Good choice Tallest fixture with 7 ft below
Under 8 ft flush mount up to 6 in (at 7 ft 6 in)
8 ft flush mount up to 12 in
9 ft flush or semi-flush up to 24 in
10 ft or higher semi-flush, pendant or chandelier up to 36 in or more

On an 8 ft ceiling, a light that hangs more than about 6–8 in can make the room feel low.

2. Choose the width

Width for the room

Add the room’s length and width in feet. The total is a good starting width in inches. With a ceiling above 9 ft, you can go about 3 in wider for each extra foot.

Room Fixture width
10 × 10 ft about 20 in
10 × 12 ft about 22 in
12 × 12 ft about 24 in
12 × 14 ft about 26 in
14 × 16 ft about 30 in
16 × 18 ft about 34 in
18 × 20 ft about 38 in
Hallways and large rooms

In a hallway, space ceiling lights about 8–10 ft apart. A large room may need two or more fixtures, or extra lamps.

What to measure

  • Room: length and width, in feet
  • Ceiling: height from the floor
  • Hallway: length, if you need more than one light
