How many pendant lights do I need over a kitchen island?

Use one pendant for islands under 4 feet, two for 4 to 6 feet, three for 6 to 9 feet, and four for longer islands. Space them evenly and hang them 30 to 36 inches above the countertop.

What size chandelier do I need for a two-story foyer?

Start with the room formula (length plus width in feet equals diameter in inches), then add 20 to 30 percent for ceilings above 14 feet. Choose a tall cascading or tiered fixture to fill the vertical space.

Q: What size chandelier do I need for my dining room?

Choose a chandelier with a diameter about one-half to two-thirds the width of your dining table, and hang it 30 to 36 inches above the tabletop.

Q: How do you calculate chandelier size for a room?

Add the room's length and width in feet; that total in inches is the ideal chandelier diameter. For example, a 12 by 14 foot room suits a 26 inch wide chandelier.

Q: How much chain do I need for my chandelier?

Subtract the hanging height and the fixture height from the ceiling height. For example, with a 9 foot ceiling, a 33 inch hang height and a 24 inch fixture, you need about 51 inches of chain and wire.

Q: Can a chandelier be too big for a dining room?

Yes. If the fixture is wider than the table itself, people will bump into it. Keep at least 6 inches of clear table edge on each side.

Choosing the right chandelier size is one of the most common lighting questions homeowners ask. Too small and it looks lost; too big and it overwhelms the room. This free chandelier size calculator by Aura Decor Living gives you the ideal fixture diameter, height and hanging height in seconds — using the same sizing rules interior designers follow.

It covers three situations: a chandelier over a dining table, pendant lights over a kitchen island, and a fixture for an open room or two-story foyer. Switch between feet/inches and meters/centimeters anytime.

Chandelier sizing rules designers follow

Over a dining table: fixture diameter should be ½ to ⅔ of the table width — never wider than the table minus 12 inches.
Open room: add the room's length and width in feet; that total in inches is the ideal diameter.
Fixture height: allow 2½–3 inches of height for every foot of ceiling height.
Above a dining table: hang the bottom of the fixture 30–36 inches above the tabletop (add 3 inches per extra foot of ceiling).
Walkways and entries: keep the bottom of the fixture at least 7 feet above the floor.
Long tables (length over 1½× the width): one linear chandelier or two pendants lights the table more evenly than a single round fixture.

Kitchen island pendant guide

One of the most asked lighting questions is how many pendant lights go over a kitchen island. The rule is simple:

Island under 4 ft (120 cm) → 1 pendant
Island 4–6 ft (120–180 cm) → 2 pendants
Island 6–9 ft (180–270 cm) → 3 pendants
Island over 9 ft (270 cm) → 4 pendants, or one linear fixture

Space pendant centers 24–30 inches apart, keep end pendants 6–12 inches from the island edges, and hang the bottoms 30–36 inches above the countertop.

Two-story foyer chandeliers

For a two-story foyer, start with the room formula (length + width in feet = diameter in inches), then add 20–30% for ceilings above 14 feet — tall volumes swallow small fixtures. Choose a tall cascading or tiered design rather than a wide shallow one, and hang it so the bottom sits around the second-floor window line, never below 7 feet from the floor.
