For a 20 ft foyer, plan on a fixture 3 to 4 ft tall. A 2 ft fixture disappears in a two-story volume. Set the width by adding the entry’s length and width in feet and reading that as inches — a 77 in wide entry carries about a 26 in diameter.
Never let the bottom hang below the top of the stair railing, and before you buy, work out how you will change the bulbs.
Two-story entries are the easiest room to under-scale and the hardest to service. Both problems are decided when you choose the fixture, not at installation.
Height first, then diameter
In a normal room you size a chandelier by diameter. In a two-story foyer the number that decides whether it works is overall height. The space is mostly vertical, and a fixture that occupies none of that height reads as an ornament stuck to a distant ceiling.
For diameter, the room-sum method still applies: add the entry’s two floor dimensions in feet and read the sum as inches. One showroom veteran, asked about a 77 in wide entry, put the workable diameter at around 26 in — and called the 12 in fixture the owner had hung roughly 30% of what the space wanted.
Two lines that set the position
The handrail
The most useful rule anyone gives for stairwell and foyer fixtures: the bottom should not fall below the top of the stair railing. Below that line it competes with the stair and looks accidental from the landing.
The upper window
If the entry has a two-story window, center the fixture on it in elevation. It is a convention rather than a rule, but it is the view from the street at night, and a fixture well above or below the window reads as unresolved from outside.
Decide how you will change the bulbs
This is the part that gets skipped, and the one people live with. Real numbers from homeowners: a 20 ft extension ladder does not reach a fixture in a 30 ft foyer. One owner rented a 12 ft step ladder. Plenty of people just leave the bulb out for years.
Choose the maintenance strategy with the fixture: long-life LED sources, an exposed-bulb design you can reach with an 11 ft pole bulb changer, or a lowering winch. Avoid enclosed domes at height — changing a bulb behind a glass dome at 20 ft means removing the dome from the top of a ladder.
Weight and access drive the install cost, not the fixture. A large foyer chandelier can weigh far more than a ceiling outlet box is rated to carry, and a heavy fixture at height needs independent support and often scaffolding. Take the specifics from your local electrical code and a licensed electrician, not from an article.
What to take away
- 20 ft foyer: 3–4 ft of fixture height. 2 ft disappears.
- Diameter from the room-sum method; a 77 in entry takes about 26 in.
- Keep the bottom above the top of the stair railing.
- Center it in the two-story window if there is one.
- Pick the bulb-changing method before the fixture.

What size chandelier for a two-story foyer?
In a 20 ft entry, 3–4 ft tall, with diameter from the room-sum method. Height matters more than diameter in a tall, narrow volume.
How low should a foyer chandelier hang?
Not below the top of the stair railing. Within that limit, position it so it reads well from the entry door and the upstairs landing.
Can you use several pendants instead of one chandelier?
Yes. In long two-story halls, a run of three larger pendants is a common alternative to a single fixture, and it can be easier to service.
Two-story entries rarely fit a stock size
Overall height, chain length, diameter and tier count are all part of the specification we hand to our partner workshops, so a fixture can be built to the volume you actually have. Send us the ceiling height and the width of the entry.
