How Many Lumens Is Good For A Projector?

How many lumens is good for a projector? This is a question that we get asked a lot, and the answer may surprise you!

Just what are lumens, anyway?

Knowing how bright a projector is can be very helpful in choosing the right one for your particular needs. But just what are lumens, and how do they relate to projector brightness?

Lumens is a measure of the total amount of visible light emitted by a source. When applied to projectors, it tells you how much light the projector is capable of sending onto the screen. The more lumens, the brighter the image will be.

Not all projectors are created equal, however. The lens quality, screen type, and other factors can all affect how bright an image appears. So while one projector might have a higher lumen rating, it might not actually produce a brighter image than another projector with a lower lumen rating.

When choosing a projector, it’s important to keep in mind what you’ll be using it for. If you need a bright image for daytime use or large presentations, you’ll want to look for a projector with a high lumen rating. If you’re mostly using your projector in a dark room for movies or gaming, you can get away with a lower lumen rating without sacrificing image quality.

Here are some general guidelines to help you choose right projector for your needs:

2000 lumens and above: Bright images in well-lit rooms; can be used for large presentations
1000-2000 lumens: Bright images in dimly lit rooms; good for smaller presentations
700-1000 lumens: Images visible in dark rooms; good for movies and gaming
500-700 lumens: Basic images visible in very dark rooms; suitable for small screens

So, how many lumens is enough?

This is, perhaps, the trickiest projector question of all to answer. It depends on so many factors: the size of your screen, the ambient light in your room, how light or dark your walls are…and even how sensitive your eyes are.

In general, though, these Lumen Guidelines should help you choose the right projector for your needs. If you have a lot of ambient light in your room or you’ll be projecting onto a large screen, you’ll need a brighter projector. If you have little ambient light and/or a small screen, you can get away with a lower lumen rating.

Business presentations in meeting rooms with controlled lighting: 1,000 – 1,500 lumens
Classrooms and training rooms with controlled lighting: 1,500 – 2,000 lumens
Home theaters in darkened rooms: 1,000 – 2,000 lumens

How bright is too bright?

The answer to this question depends on a few factors, including the size of the room, the amount of light available, and the type of projector you’re using. Generally speaking, however, you’ll want a projector that produces at least 1,000 lumens for a small room or 2,000 lumens for a large room. If you’re using a projector in an environment with ambient light (such as a classroom or conference room), you’ll need an even higher lumen count to ensure that your image is visible.

The bottom line on lumens

In a home theater or office, you generally want a projector that can produce around 1,000 to 2,000 lumens. That’s enough light for most rooms, and it will give you a bright, clear image with good color saturation. If you have a particularly large room or a lot of ambient light, you may want a projector with 3,000 lumens or more.


It is safe to say that for most people, a lumen level of around 2,000 will be more than adequate. This is assuming that you are projecting onto a screen or white wall in a darkened room. If you are using your projector in a brighter environment, you may need a higher lumen level to compensate.

Keep in mind that the lumen level is only one aspect of choosing a projector. You will also need to consider the resolution, contrast ratio, and other features to ensure that you are getting the best possible image quality.
