Most rooms are dramatically under-lit — not because the fixtures are wrong, but because nobody did the lumen math. Lighting designers work from a simple target: each room type needs a specific amount of light per square foot. Hit that number and the room feels warm and functional; miss it and even expensive decor falls flat.

Our luxury lighting calculator applies those professional standards to your exact room. Whether you’re planning a cozy bedroom or a task-heavy kitchen, you’ll know precisely how many lumens the space needs — and how to split them across ambient, task, and accent layers.

How the lighting calculator works

Choose your room type and enter its dimensions. The calculator returns the total lumens required, based on recommended foot-candle levels for that space, plus a suggested breakdown across lighting layers. It’s the same starting point a lighting designer would use — distilled into a thirty-second calculation.

Light in layers

One overhead fixture per room is the fastest way to flat, unflattering light. Aim for at least three sources at different heights: ambient for overall glow, task for reading and work, accent for art and architecture. And remember that great lighting is one of the simplest ways to make any space feel more refined — see how to make your home look more expensive for proof.

Get the lumens right and everything else glows.
