Purchasing a projector requires you to think about what type of lighting conditions you’re going to use it in. One of the ways to counteract a well lit room is to invest in a projector with a higher brightness; brightness in projectors is measured by lumens. So, you might ask your self, “How many lumens do I need projectors?”

We will give you a guide to help you answer the question we raised above as well as the question “How can lumens impact my viewing pleasure?”

The level of lumens and intensity won’t affect the overall quality of the images projected. The only reason you may want to choose a projector with a particular range of lumens is when the light level of the room you are watching in will profoundly impact your viewing. Choosing a projector which has the appropriate lumens output will allow you to watch images in your designated viewing area without eyestrain.

How Many Lumens Do I Need Projectors: The Factors

1. Types of Projector

There are a few different types of projectors available on today’s market. The projectors within each category have a range of lumens over which they operate. Lumens is the same as brightness. Lower levels of projector lumens are better for darker rooms and vice-versa.

Here is a quick guide on what types of projectors are available:

  • Home Theater Projector

Home theater projectors are excellent for watching movies, playing video games, and watching your favorite TV shows. You can connect them up to a cable box, PC, or a video game console.

These types of projectors work best in dark rooms and dim lighting, so make sure that you have a designated space in your home where the projector will literally shine at it’s best. Also, home theater projectors function at around 1,000-2,000 lumens, which make them ideal for extended use, as the brightness won’t cause your eyes extra strain or stress.

  • Business Projectors

The next type of projector are business projectors. These are the types of projectors that you’ll see at schools, company meetings, and social lectures. They are often installed on the ceiling and feature adjustable settings.

You can expect these types of projectors to work best in medium lit rooms, which is ideal for shorter screenings. These projectors have around 2,000-3,000 lumens, and you’ll find that these are bright enough to be easy to see images from a distance.

  • Portable Projectors

The last type of projector you’ll see on the market are portable projectors. These are ideal for small get-togethers, outdoor movies, or meetings. They feature high lumens which range from 3,000 to 4,500 because they need better contrast against the objects you’re projecting them on.

While many people enjoy these types of projectors, you’ll find that they can be stressful on the eyes and can give you a headache. Limiting your use to only an hour or two is ideal.

2. Room’s Brightness

The biggest factor is going to be what the level of lighting the room you’re projecting in is going to be like. You’ll find that projectors function better in darker rooms, as this will allow the projector to create a contrast between the images and the dark background with less lumens. Less lumens means a longer viewing time with less chance of eyestrain. But what if you don’t have the luxury of having a dim room?

You can instead decide to purchase a projector with a different level of brightness. You’ll find that for a home theater, you should look for projectors between 1,000 and 2,000 lumens. However, if you’re planning on using a 2,000-lumen projector for movies, you may find that it could be too harsh on your eyes and isn’t the best for long-term projector use.

For portable projectors and business projectors that you can use in lighter settings, you may want to consider 2,000 to 3,000 lumens. 2,000 to 3,000 lumens will provide better lighting and brightness which can help with these rooms. If you’re looking to place the projector in a classroom or business room, then you may even want to go brighter than 3,000 lumens.

What Can I Do to Adjust a Projector?

Luckily, even if you bought a projector that isn’t the right type for the room you’re projecting in, there are still settings you can tinker with to make it ideal for the room.

The very first adjustment you can make is by customizing the room. Close all doors, put up blinds and curtains on the windows, and adjust the lights to the lowest setting or turn them off. This can help the brightness if you’ve got a projector with too low of a setting. Conversely, try opening the room up to the light if your projector has too high of a lumens setting.

The next step is to play around with the picture mode. When you purchase a projector, you’ll be prompted to change the picture setting to the type of image display modes you’re using for the projector.

If you’re watching movies, there’s an option for movies or cinematics. If you’re watching sports or other live footage, adjust the picture mode to a motion setting. There are also settings for pictures, presentations, and more.

The last step you can take to creating a balance between room and projector brightness is to adjust the settings on the projector. You’ll find the settings by either playing around with the buttons on the projector or the remote. These settings allow you to fully customize the brightness, color, and contrast on the picture. Use it to adjust it to the room you’re using.

The best way to get the results you want is to display a picture or video where you’ll be using it, or people would be watching and use a combination of adjusting the room and projector brightness.


Finding a projector that suits your type of viewing is going to be your best bet when it comes to getting the correct lumens. Adjust the lighting of the  room you’re going to be using it in and learn to adjust the settings on the projector if you’re still not satisfied with the brightness of the screen.

You can’t go wrong when you’re purchasing a projector, as all of them are designed for creating a significantly brighter display. The brighter the projector, the more strain you’ll be putting on your eyes, so be sure to limit your screen time if you have a projector with high lumens. Other than that, we hope you’ve learned what you wanted to know about “How many lumens do I need projectors?”
