Choosing the right size light is the single most common struggle in lighting a home. Too small and the fixture looks lost. Too big and it overwhelms the room. This lighting size guide gives you simple, reliable rules for pendants, chandeliers, wall sconces, and table lamps, room by room.
Lighting size guide: the golden rule of fixture size
When in doubt, go slightly larger than you think. Almost everyone underestimates. A fixture that looks generous in a photo looks modest once it is hanging in a real room with real ceiling height. Designers consistently say the most common sizing mistake is choosing a light that is too small.
Pendant size guide: the basics
Diameter. For a pendant over a table or island, choose a fixture with a diameter roughly one half to two thirds the width of the surface below it. A 120 cm wide dining table suits a pendant 60 to 80 cm across. For more detail, see our dedicated pendant size guide.
Hanging height. Hang pendants 75 to 90 cm (30 to 36 inches) above the table or counter surface. This keeps the light out of sightlines while lighting the surface well. Over a kitchen island where people stand, you can hang slightly higher, 80 to 95 cm above the counter.
Multiple pendants. For a long island or table, use two or three smaller pendants instead of one large one. Space them evenly, leaving about 60 to 75 cm (24 to 30 inches) between each fixture, and keep the end pendants at least 15 cm (6 inches) from the edge of the surface.
Entryway pendants. In a foyer, the bottom of the pendant should hang at least 210 cm (7 feet) above the floor so tall guests walk under it comfortably. In a two story entryway, hang the fixture so it is visible from the upper landing, usually with the bottom third of the fixture at or below the second floor line.
Chandelier sizing
The room formula. Add the room's length and width in feet. That number, in inches, is a good starting diameter for your chandelier. A 12 by 14 foot dining room (26 total) suits a chandelier about 26 inches, or 65 cm, across. For a quick metric version: add length and width in meters, multiply by 8, and treat the result as centimeters of diameter. A 4 by 5 meter room gives 72 cm.
Hanging height over a table. Hang the bottom of the chandelier 75 to 90 cm (30 to 36 inches) above the tabletop. Higher ceilings can take the higher end of that range. Our dining room chandelier size guide goes deeper on dining rooms specifically.
Chandeliers in open rooms. Without a table to anchor to, hang the bottom of the chandelier at least 210 cm (7 feet) above the floor. In rooms with ceilings above 3 meters, add about 8 cm of hanging height for every 30 cm of extra ceiling height.
Width relative to the table. A chandelier should be about one half to two thirds the width of the dining table, and never wider than the table itself. A fixture wider than the table crowds the place settings and risks bumps from chairs.
Wall sconce sizing and placement
Height. Mount sconces so the center of the light source sits 150 to 170 cm (60 to 66 inches) from the floor in living areas and hallways. Beside a bed, mount lower, 120 to 135 cm from the floor. Full details are in our wall sconce height guide.
Scale. A sconce should feel proportional to what it flanks. Beside a standard door or a 150 cm mirror, a sconce 25 to 40 cm tall works well. Oversized sconces flanking a small mirror look top heavy. Undersized sconces beside a grand fireplace disappear.
Spacing. In hallways, space sconces 180 to 240 cm (6 to 8 feet) apart. Beside a bed or bathroom mirror, 90 to 120 cm (36 to 48 inches) apart. Keep spacing consistent. The eye notices uneven gaps immediately.
Table lamp sizing
Total height. A table lamp should stand 60 to 75 cm tall including the shade for most side tables and console tables. The bottom of the shade should sit at about eye level when you are seated nearby, roughly 100 to 110 cm from the floor. This hides the bulb from direct view and spreads light comfortably.
Shade proportions. The shade's bottom diameter should be roughly equal to the lamp base height, and the shade should be about two thirds the height of the base. A shade wider than the table it sits on looks unstable, so keep the shade narrower than the tabletop.
Bedside lamps. Choose a lamp whose total height is about two thirds the height of the headboard, or simply make sure the bottom of the shade sits just above the mattress line when you sit up in bed. The lamp should not tower over the nightstand or get lost behind it.
Flush mounts and semi flush mounts
For hallways and rooms with low ceilings, fixture diameter follows the same room formula as chandeliers, but keep the profile shallow. A good rule: the fixture's drop from the ceiling should be no more than one tenth of the ceiling height. In a 2.4 meter ceiling room, keep the fixture within 24 cm of the ceiling so the room still feels open.
Sizing for Moroccan and pierced fixtures
Pierced brass fixtures deserve one extra consideration. Because they project patterned light, an undersized pierced fixture does double duty badly: it neither lights the room nor shows off its pattern. Give pierced pendants and chandeliers the generous end of every range above. A large pierced chandelier hung at the right height will wash the whole room in pattern. A small one hung too high just makes a bright spot on the ceiling.
Also remember that pierced fixtures read larger than solid ones. The eye follows the pattern outward, so a 60 cm pierced pendant holds visual weight like a bigger solid shade. This is one case where the "go slightly larger" rule needs a light touch. Generous, not giant.
Common sizing mistakes
- Choosing a dining chandelier narrower than half the table width. It looks like an afterthought.
- Hanging pendants so high they light the ceiling instead of the counter.
- Using one small pendant where two medium ones would balance the space.
- Forgetting to measure the open door swing near a hanging fixture.
- Ignoring the fixture's visual weight. Dark, dense fixtures feel bigger than airy pierced ones of the same size.
Frequently asked questions
What size chandelier do I need for my dining room?
Add the room's length and width in feet. The total, in inches, is a good chandelier diameter. The fixture should also be one half to two thirds the width of your table and hang 75 to 90 cm above it.
How big should pendant lights be over a kitchen island?
Each pendant's diameter should be about one half to two thirds the island's depth, and pendants should be spaced 60 to 75 cm apart. Hang them 75 to 90 cm above the counter surface.
Are my wall sconces too small?
If they look lost next to the mirror, door, or fireplace they flank, probably. A good sconce is 25 to 40 cm tall for standard applications and mounted with its center 150 to 170 cm from the floor.
Should a chandelier be wider than the dining table?
No. Keep it between one half and two thirds of the table width. A fixture wider than the table overwhelms the setting and gets in the way.
How do I size lighting for a room with very high ceilings?
Scale up. Add about 8 cm of hanging height per 30 cm of ceiling above 3 meters, and choose fixtures at the generous end of the diameter ranges. Tall rooms swallow small fixtures.
