Add the length and width of your room in feet, and that number is your chandelier diameter in inches. A 14 by 16 foot living room takes a 30-inch chandelier. Over a dining table, ignore the room and size to the table instead: the fixture should be half to two-thirds the table width, hung 30 to 36 inches above the tabletop.
That covers most rooms. The rest of this guide is for everything the formula doesn't handle — low ceilings, rectangular tables, two-story entryways, and the reason so many chandeliers end up looking undersized once they're actually on the ceiling.
The two numbers you need, not one
Nearly every sizing guide gives you a diameter and stops. Diameter is the easy half.
The number that decides whether a room looks right is fixture height — how much vertical space the chandelier occupies. Get the diameter right and the height wrong, and you end up with a wide, flat disc floating in a two-story foyer, or a 40-inch-tall crystal cascade hanging in a room with 8-foot ceilings that everyone has to duck around.
The working rule: allow 2.5 to 3 inches of fixture height for every foot of ceiling height.
| Ceiling height | Fixture height |
|---|---|
| 8 ft | 20–24 in |
| 9 ft | 23–27 in |
| 10 ft | 25–30 in |
| 12 ft | 30–36 in |
| 16 ft+ (two-story) | 48 in and up |
Check this number on the product page before you check anything else. It's the spec most people skip, and it's the one that can't be fixed after delivery.
How to size a chandelier in four steps
- Measure the room — length and width in feet. Add them. That sum, in inches, is your starting diameter.
- Measure the ceiling — floor to ceiling in feet. Multiply by 2.5 to 3. That's your fixture height range.
- Check what's underneath. If there's a table, an island, or a bed under the fixture, the object overrides the room. Size to the object (see below).
- Set the hanging height. Bottom of the fixture sits 7 feet above the floor in open walking space, or 30 to 36 inches above a tabletop.
Do step 3 before you fall in love with a fixture. A dining room and a living room of identical dimensions take very different sizes, because one has a table in it.
Dining rooms: size to the table, not the room
The table wins. Always.
Round or square table: the chandelier diameter should be half to two-thirds of the table width.
| Table width | Chandelier diameter |
|---|---|
| 36 in | 18–24 in |
| 42 in | 21–28 in |
| 48 in | 24–32 in |
| 54 in | 27–36 in |
| 60 in | 30–40 in |
| 72 in | 36–48 in |
Then run one sanity check: leave at least 6 inches of bare table showing on every side. On a 48-inch round table, that caps you at 36 inches no matter what the formula says. This is the rule that keeps people from clipping the fixture with a wine glass while reaching across the table.
For a 42- to 48-inch round table, something in the 24-inch range sits right in the middle of the band — the Tabitha Alabaster Chandelier is 23.6 inches across and 6.3 inches tall, which also makes it workable under a standard 8-foot ceiling. For a 60-inch or larger table, you're into 30 to 40 inches: the Murano Chandelier at 31.5 inches, or the Fiore Crown Chandelier at 39 inches for a genuinely large table.
Rectangular or oval table: stop using diameter. A single round fixture over a 90-inch rectangular table leaves both ends of the table dark and looks stranded.
Use a linear fixture instead, sized to half to two-thirds the table length, centered. A 72-inch table wants something in the 36- to 48-inch range; a 96-inch table wants 50 to 64. The Soltaire Linear Chandelier runs 37, 50, 60, 70, 87, and 120 inches wide, which covers essentially every rectangular table anyone owns. The Theron Linear Chandelier comes in 50 and 60. Browse the full range of linear chandeliers if that's your table shape.
An oval fixture does the same job with softer corners. The Ghiaccio Glass Oval Chandelier comes in 54 and 65 inches wide, which suits tables from roughly 80 to 100 inches long.
Two fixtures is the other correct answer on a long table. Over 96 inches, two smaller pendants spaced evenly usually read better than one enormous linear piece.
Hanging height over a table: 30 to 36 inches above the tabletop on an 8-foot ceiling. Add 3 inches for every foot of ceiling above that. Nine-foot ceiling, 33 to 39 inches. Ten-foot ceiling, 36 to 42.
Nobody walks under a dining chandelier, so the 7-foot floor clearance rule doesn't apply here. That's why dining fixtures hang lower than anything else in the house.

Living rooms: the room formula, with a ceiling check
This is where length-plus-width earns its keep.
| Room size | Chandelier diameter |
|---|---|
| 10 × 12 ft | 22 in |
| 12 × 14 ft | 26 in |
| 14 × 16 ft | 30 in |
| 15 × 18 ft | 33 in |
| 18 × 20 ft | 38 in |
| 20 × 24 ft | 44 in |
Center it in the room, not over the coffee table — unless the seating is arranged around a clear center, in which case the seating wins.
Bottom of the fixture: at least 7 feet above the floor. This isn't a style preference. It's the clearance that keeps a 6'2" guest from walking into it.
That clearance requirement is what makes ceiling height the deciding factor in a living room. On an 8-foot ceiling you have 12 inches of hanging space to work with, total — canopy, chain, and fixture body all have to fit inside it. A 30-inch-wide fixture that's 30 inches tall simply will not go in that room.
The fix is a low-profile fixture: full diameter, minimal height. The Marika Alabaster Chandelier is 31.5 inches across and 3.1 inches tall. That's the shape of fixture an 8-foot ceiling needs. A flush mount is the same idea taken further.
At 10 feet and up, the constraint disappears and you can hang whatever you like. See living room chandeliers, or our guide to choosing a chandelier for your living room.
Entryways and two-story foyers
Two rules govern here, and neither is the room formula.
Rule one: 7 feet of clearance, minimum. Measure from the floor of the entry to the bottom of the fixture. In a single-story entry with an 8-foot ceiling, that leaves you 12 inches — you need a flush or semi-flush fixture, not a chandelier.
Rule two, for two-story foyers: hang it in the window. If your entry has a tall window above or beside the door, the bottom of the fixture should sit roughly at the center of that window. It's the view from the street, and it's the one placement decision people regret most.
For height, a two-story foyer typically runs 18 to 20 feet, which puts you at 48 to 72 inches of fixture height. That sounds enormous on paper. It isn't — vertical space at that scale swallows anything smaller.
Diameter follows the entry footprint: an 8 by 10 foot entry takes 18 to 20 inches wide, but 60 inches tall. Tall and narrow, not wide and flat. Fixtures built for this shape include the Rock Alabaster Chandelier at 31.5 inches wide by 78.7 inches tall, and the multi-tier crystal pieces in entryway lighting, which run from 63 to 118 inches of drop.
If your foyer ceiling is over 20 feet, see extra-large chandeliers.
Bedrooms
Use the room formula, then take 2 to 4 inches off. A bedroom chandelier that's technically correct often reads as too aggressive over a bed.
| Room size | Chandelier diameter |
|---|---|
| 10 × 12 ft | 18–22 in |
| 12 × 14 ft | 22–26 in |
| 14 × 16 ft | 26–30 in |
Center it in the room rather than over the bed if the bed isn't centered. If you do hang it over the bed, keep the fixture entirely within the footprint of the mattress and keep the bottom at least 7 feet up.
Warm light matters more than size here — every fixture we ship is 2700K warm white and dimmable on an E26 socket, which is the combination you want in a bedroom. Bedroom lighting.
Kitchen islands
Islands follow the rectangular-table logic, with one addition: keep the fixture narrower than the island itself, so nothing hangs over the working edge.
- Island up to 60 in: one fixture, 30–40 in wide, or two pendants
- Island 60–84 in: linear fixture 37–50 in, or two to three pendants
- Island 84 in and over: linear fixture 50–70 in, or three pendants
Hanging height is lower than a dining table: 30 to 34 inches above the countertop, because you want light on the work surface and countertops sit higher than tables. Kitchen island lighting.
Five sizing mistakes we see repeatedly
1. Going too small. This is the most common error by a wide margin, and it happens because fixtures look larger in a product photo than they do installed. A 20-inch chandelier that filled the frame on your screen occupies almost nothing on a 12-foot ceiling. When you're between two sizes, take the larger one.
2. Sizing to the room in a dining room. The table overrides the room. A 16 by 18 foot dining room with a 48-inch round table takes a 24- to 32-inch fixture, not the 34 inches the room formula suggests.
3. Ignoring fixture height on an 8-foot ceiling. Diameter is fine, height is fatal. Check it first.
4. Using one round fixture over a rectangular table. Round fixture, rectangular table: the ends go dark and the proportions fight each other. Go linear, or go with two.
5. Hanging a foyer chandelier too high. Tucking it up near the ceiling to be safe is the instinct, and it's wrong. It disappears from the room and from the window. Bring it down to window center.

Frequently asked questions
What size chandelier for a 6-foot dining table?
A 72-inch rectangular table takes a linear fixture 36 to 48 inches long. If it's a 72-inch round table, you want 36 to 48 inches in diameter. Hang either one 30 to 36 inches above the tabletop.
How low should a chandelier hang from a 10-foot ceiling?
Over a table, 36 to 42 inches above the tabletop. In open space, position the bottom 7 to 7.5 feet above the floor, which leaves roughly 30 to 36 inches of fixture and chain below the canopy.
Can a chandelier be too big?
Yes, but it's rare, and the failure is usually about height rather than width. An oversized-but-flat fixture reads as intentional. A fixture that forces people to walk around it does not. Over a table, the hard limit is 6 inches of clear table on each side.
What size chandelier for a two-story entryway?
Height matters more than diameter. For an 18- to 20-foot ceiling, look for 48 to 72 inches of total fixture height and 18 to 30 inches of width. Position the bottom at the center of the entry window, and never less than 7 feet off the floor.
Can I hang a chandelier over a bathtub?
Only in specific positions. US electrical code restricts where a hanging fixture can sit relative to a tub or shower, and the answer depends on your ceiling height and the tub's location. This is a code question, not a design question — have your electrician confirm the placement before you order. Bathroom lighting.
Does a bigger room always mean a bigger chandelier?
Not if the ceiling is low. On an 8-foot ceiling, a large room calls for a wide, shallow fixture — or two smaller fixtures — rather than one tall one. Diameter scales with the room; height scales with the ceiling.
Getting the size right before you order
Every fixture we sell lists its exact diameter and height in the size options, in inches. Measure your room, run the two formulas, then match those numbers against the spec before you choose a finish or a style.
If you're between two sizes and can't decide, email us at info@lamerlighting.com with your room dimensions, ceiling height, and table size. We'll tell you which one fits.
All orders ship free, bulbs are included at no charge, and every fixture carries a 2-year warranty. Chandeliers are hardwired — plan on a licensed electrician for installation.
