The Design Lab · Lighting Tools
Three tools. One lighting system.
Every one of these runs on the same method: start from the room and the light it needs, then work back to the fixtures. Two are free and focused. One plans a whole house. Here is what each does, so you can pick the one that fits where you are.
Room Lighting Calculator
One room at a time. Enter the dimensions, ceiling height, and natural light, and get the lighting that room actually needs.
Best for
Planning or sanity-checking a single room before you shop.
- Ambient, task, and accent lumen targets
- Recessed fixture count and spacing
- Color temperature for the room
- Use it as many times as you like
Free, no sign-up
Fixture Sizing Calculator
You already know you're hanging a fixture. This sizes it to the room and the furniture below it, so it reads right.
Best for
Getting the diameter, count, and hanging height of a pendant or chandelier right.
- Fixture diameter range for the space
- Count and spacing over a table or island
- Mounting and drop heights
- Works with the room calculator
Free, no sign-up
