Plan your room lighting with ease! Our free Lighting Layout Planner helps you calculate fixtures and placement for any space. Try it now!


Lighting a room properly can transform its look and feel, but where do you start? Designing a lighting plan might seem daunting, especially if you’re unsure how many fixtures you need or where to place them. That’s where a tool like our room illumination planner comes in handy. It takes the mystery out of the process by calculating the basics for you, based on your space’s size and purpose.
Good lighting isn’t just about brightness—it’s about creating a mood, highlighting key areas, and ensuring functionality. A well-lit kitchen, for example, needs focused task lighting over counters, while a cozy bedroom might benefit from softer, ambient glows. Without a clear plan, you risk uneven illumination or wasted energy.
Start by considering the room’s primary use. Then, think about layering—combine overhead lights with task or accent options for versatility. Tools that help map out fixture placement can save you time and prevent costly mistakes. Whether you’re refreshing a home office or revamping a dining area, a thoughtful approach to brightness makes all the difference. Remember, though, that digital planners offer estimates; for complex projects, a professional’s input is invaluable.
Our tool provides a solid starting point based on standard lighting guidelines, like lumens per square foot for different room types. For instance, kitchens often need 50-70 lumens per square foot, while living rooms might only require 20-30. That said, every space is unique—factors like wall color or natural light can affect the outcome. We always recommend chatting with a lighting expert or electrician for a final, precise design.
This planner is designed specifically for indoor rooms like kitchens, offices, or bedrooms. Outdoor lighting has different requirements, such as weatherproof fixtures and safety considerations, which our algorithm doesn’t account for. If you’re looking to light up a patio or garden, you might want to explore specialized tools or consult with a pro who knows outdoor setups.
No worries! If you input invalid data—like a negative number or something that doesn’t make sense—our tool will gently nudge you with a helpful error message to correct it. We’ve built it to be user-friendly, so you’ll know exactly what to fix. Just double-check your measurements, re-enter them, and you’ll get your lighting plan in no time.
