Size Your Space

Getting the size right is the difference between a fixture that looks intentional and one that looks like a guess. This page is a quick-start map to the sizing question you're actually asking — each section below gives you a starting point, then links to our full guide for the exact numbers, standards citations, and room-by-room exceptions.

Chandeliers

The three questions that matter: how wide should it be for the room, how high should it hang over a table, and how much clearance do you need below it. Chandelier sizing isn't one flat number — it scales with ceiling height, table size, and whether it's the room's only fixture.

Kitchen Islands & Pendants

As a starting point, most islands look best with pendants spaced with an odd number across the counter and hung with enough clearance to keep sightlines clear across the kitchen — but the right count, spacing, and height shift with island length, ceiling height, and whether you're using one large fixture or several smaller ones.

Bathroom Vanity Lighting

Good vanity lighting is about lighting your face, not your ceiling — placement and fixture width both matter more than raw brightness. Our full guide covers sconce vs. bar placement, mounting height, and how to avoid the shadows that make vanity lighting frustrating to shop for.

How Bright Should the Room Be?

"How many lumens do I need" doesn't have one universal answer — it depends on room size, ceiling height, and how the room is used. Our full guide translates the lighting industry's actual brightness standard into real numbers you can shop against, room by room.

Layered Lighting

One ceiling fixture is almost never enough on its own — most rooms look and function best with ambient, task, and accent lighting working together. If a room feels flat or leaves you reaching for lamps, layering is usually why.

Low Ceilings & Semi-Flush Mounts

Under roughly 8 feet, a hanging fixture can eat up clearance fast — going wider with a semi-flush mount instead of lower with a pendant is usually the fix. Not sure what fits your ceiling? Our low-ceilings guide includes the Ceiling Genius, an interactive tool that asks a few questions about your room and recommends a fixture size and mount type on the spot.

Color Temperature & CRI

Fixture size is only half the sizing question — for spaces like vanities where you're checking your own appearance under the light, color rendering (CRI) and color temperature matter as much as placement. Our full guide breaks down what those numbers mean and what to look for.

Lighted Mirrors

A lighted mirror needs to be sized to the vanity and mounted at the right height to actually do its job — too small or mounted wrong, and the light doesn't reach your face. Our full guide covers sizing ratios and mounting height for both standing and mixed-height households.

A note on accessibility and code

The guidance above reflects general lighting-industry design practice. If you're installing in a space with ADA accessibility requirements or local electrical code considerations — mounting heights near tubs and showers, for example — check your local code and an ADA reference alongside these guidelines before finalizing your install.
