How to size a chandelier for a great room: add the room's width and depth in feet, and read the total as the fixture diameter in inches. A 20 ft × 24 ft great room therefore wants a chandelier about 44 in (112 cm) across, with its lowest point 84 in (213 cm) above the floor.
The additive sizing rule, and why a great room is not a dining room
The great-room rule is additive: measure the room's width and depth in feet, add the two numbers, and treat the total as the chandelier's diameter in inches. A 20 ft × 24 ft great room gives 44, so the target diameter is 44 in, or 112 cm. A dining room is sized against the table instead of the room, and a fixture about 12 in (30 cm) narrower than the tabletop is the conventional starting point. The two methods diverge because a great room contains no single piece of furniture to size against; the chandelier has to hold an open volume. In a two-storey great room that volume is vertical as well as horizontal, so the same 112 cm fixture can still read as undersized when the ceiling runs to 20 ft (6.1 m). Treat the additive figure as a floor, not a ceiling.
Converting the result into centimetres before you order
Most European and Asian suppliers, including PALERILL, publish chandelier diameters in centimetres, so convert the inch figure once and work in one unit from then on. Multiply inches by 2.54: 44 in becomes 111.8 cm, which rounds to 112 cm. The reverse conversion is centimetres divided by 2.54, so a 150 cm fixture is 59.1 in and a 200 cm fixture is 78.7 in. Rounding matters at the order stage, because diameter options are usually offered in fixed steps rather than in continuous sizes. PALERILL's product copy states inch equivalents alongside centimetres for 569 of its 1,046 active products, so buyers working in inches can check the majority of listings without doing the arithmetic themselves. When the additive rule lands between two offered diameters, take the larger one for a double-height space and the smaller one for a room with an 8 ft (244 cm) ceiling.
What a catalogue actually stocks in large diameters
A sizing rule is only useful if the fixture exists in that size, so it is worth checking what a catalogue can actually supply. Of PALERILL's 1,046 active products, 515 state a machine-readable diameter range in the product copy, and 481 of those fall inside physically plausible limits for a chandelier. Within that 481-model sample, 319 models reach 100 cm (39.4 in) or more, 215 reach 120 cm (47.2 in), 145 reach 150 cm (59.1 in), and 39 reach 200 cm (78.7 in). The largest advertised diameter in the catalogue is 287 cm (113.0 in) and the smallest is 20 cm (7.9 in). Only 27 of the 481 begin at 100 cm or above, which means the overwhelming majority of large fixtures are scaled up from a smaller base rather than sold only at their maximum size.
| Upper diameter reached | Models | Share of the 481-model sample | Typical room this fits |
|---|---|---|---|
| 100 cm (39.4 in) and over | 319 | 66.3% | Bedroom, dining room, small foyer |
| 120 cm (47.2 in) and over | 215 | 44.7% | Living room, open-plan kitchen |
| 150 cm (59.1 in) and over | 145 | 30.1% | Great room, stairwell, double-height void |
| 200 cm (78.7 in) and over | 39 | 8.1% | Hotel lobby, atrium, very tall great room |
How much drop a tall ceiling needs
Drop is the distance from the ceiling to the top of the fixture, and in a great room it is the number that decides whether a correctly sized chandelier looks right. The lower edge of the fixture should sit at least 84 in (213 cm) above the finished floor so people can walk beneath it, and in a double-height space the fixture itself conventionally occupies the upper third of the empty vertical run. A 20 ft (6.1 m) ceiling in a great room therefore leaves a 7 ft (213 cm) clearance at the bottom and places the chandelier roughly between 13 ft (396 cm) and 20 ft (610 cm) above the floor. PALERILL lists an adjustable drop on its large models, and product copy names double-height interiors for 39 models and stairwells for 129, so the suspension length is a specification to confirm rather than assume.
What a large chandelier costs, by diameter
Price rises with diameter, but not evenly, and in the current catalogue the steepest step is between the 100–149 cm and the 150–199 cm classes. Across the 481 PALERILL models with a measurable diameter, taking each model's cheapest configuration, the under-100 cm class has a median of $686. The 100–149 cm class has a median of $980, the 150–199 cm class $1,675, and the 200 cm and over class $1,883. Moving from the 100–149 cm class to the 150–199 cm class adds about 71 per cent to the median, while moving from the 150–199 cm class to 200 cm and over adds only about 12 per cent. Diameter is not the only price driver: within the 200 cm and over class the most expensive model starts at $18,880, and the dearest single configuration among these 481 models is $48,800.
| Maximum diameter | Models priced | Entry price | Median | Highest model entry |
|---|---|---|---|---|
| Under 100 cm | 162 | $98 | $686 | $4,030 |
| 100–149 cm | 174 | $95 | $980 | $4,795 |
| 150–199 cm | 106 | $160 | $1,675 | $7,272 |
| 200 cm and over | 39 | $184 | $1,883 | $18,880 |
Read the table this way: the median is taken over each model's cheapest configuration, and "entry" is the lowest of those figures in the class. A model's maximum diameter is usually reached by its largest variant, so a class that reaches 200 cm still contains models whose entry configuration is a small, cheaper size of the same design. Fixture price is only part of a project budget — rigging, access equipment and the electrical work at height are quoted separately, and our high ceiling chandelier installation cost breakdown sets out what those items cover.
Two worked ladders from the catalogue show how the steps land on one model family. AM0001 is offered in six configurations: 80 cm diameter with a 1.3 m height at $1,769, rising through 1.2 m at $3,299 and 1.5 m at $4,999, to 2 m with a 3 m height at $8,399. AM0122 uses the same six diameter steps and runs from $1,483 at 80 cm to $7,883 at 2 m.
Designing a great room around the fixture, in order
Work outward from the fixture. A chandelier is the least flexible element in a great room: the ceiling height and the floor area are fixed long before the lighting is chosen, and a fixture ordered in the wrong diameter cannot be adjusted on site. Sizing first also keeps the budget honest, because diameter moves the price in steps rather than smoothly — the 150–199 cm class has a median entry of $1,675 against $980 for the 100–149 cm class, a step of about 71 per cent. There are five steps in the sequence below, and the order matters. Steps 1 and 2 fix the target diameter. Step 3 fixes the drop, which is the variable most often left until installation and the one that most often makes a correctly sized chandelier look wrong. Steps 4 and 5 turn the sizing decision into a buildable order: configurations first, then the drawing.
- Measure the room's width and depth at floor level, in feet, and add the two figures to get the target diameter in inches.
- Convert that figure to centimetres by multiplying by 2.54, then round to the nearest diameter the catalogue actually offers.
- Confirm the ceiling height and decide the drop, keeping at least 84 in (213 cm) of clear space beneath the fixture.
- Check the number of offered configurations before choosing, because the median PALERILL model is available in 6 configurations and some run to 90.
- Ask for the dimensional drawing before production, so the diameter, height and drop are fixed as a set rather than one at a time.
When a great room is not the right choice for a chandelier
A chandelier is not recommended for every tall room, and the cases where it disappoints are predictable. If the great room's ceiling is flat at 8 ft (244 cm), the additive rule can produce a diameter the room cannot carry: a 44 in (112 cm) fixture at that height will sit low in the sightline and dominate the seating area, so a smaller pendant or a pair of fixtures is the better answer. A great room whose ceiling is pitched rather than flat is a second case, because the mounting point moves with the slope and the clearance rule becomes harder to hold. Third, an open-plan great room that combines kitchen, dining and living functions usually has more than one centre of gravity; a single large fixture hung over the seating group leaves the other two zones unlit, and a layered lighting plan serves the room better than one statement chandelier.
FAQ: sizing a chandelier for a great room
What size chandelier for a 20 ft × 24 ft great room? Add 20 and 24 to get 44, so the target diameter is 44 in, or 112 cm. Round up to the nearest offered diameter if the ceiling is above 12 ft (366 cm).
Is a 2 m chandelier too big for a great room? Only 39 of the 481 measurable PALERILL models reach 200 cm, and the median entry configuration in that class is $1,883, so 2 m is a deliberate specification rather than a default. It suits a double-height void; it is oversized for a single-storey room.
How far above the floor should a chandelier hang in a two-storey room? Keep the lowest point at 84 in (213 cm) or more above the finished floor, and let the fixture occupy the upper third of the empty vertical run.
How do I convert chandelier sizes between inches and centimetres? Multiply inches by 2.54 to get centimetres, or divide centimetres by 2.54 to get inches. A 150 cm fixture is 59.1 in; a 200 cm fixture is 78.7 in.

Two limits worth stating plainly. First, the diameter figures are read from the product copy, not measured on a light bench; a few listings carry diameter text that does not match their own variant options, and 34 listings were excluded from the sample for that reason. Second, PALERILL does not publish a per-model weight table, so this article gives no weight or ceiling-load figures: those depend on the chosen configuration and are confirmed at drawing stage.
