When it comes to presenting or displaying information, it’s important to make sure that your audience can see and read the content clearly. This is especially true when presenting in daylight, as the extra ambient light can make it harder to see a projected image. So, how many lumens do you need to project in daylight? The answer depends on a few different factors, including the size of the screen or surface you’ll be projecting onto, the distance between the projector and the screen, and the level of ambient light in the room. In this article, we’ll delve into these factors and provide guidelines to help you choose the right lumen output for your needs.

How Many Lumens Do You Need to Project in Daylight?
The number of lumens you need to project in daylight will depend on several factors, including the size of the screen or surface you’ll be projecting onto, the distance between the projector and the screen, and the level of ambient light in the room. Here’s a breakdown of these factors and how they can impact your lumen needs:
Screen size:
The larger the screen or surface, the more lumens you’ll need to ensure that the image is bright and clear. This is because the light from the projector has to cover a larger area, which can dilute the brightness of the image. As a general rule of thumb, you’ll need at least 1,000 lumens for a screen size of up to 80 inches, and 2,000 lumens or more for screens larger than 80 inches.
Distance between projector and screen:
The closer the projector is to the screen, the fewer lumens you’ll need. This is because the light from the projector is more concentrated at close range, which makes the image appear brighter. Conversely, the farther the projector is from the screen, the more lumens you’ll need to compensate for the loss of brightness. A good rule of thumb is to aim for 100 lumens per square foot of screen size when the projector is positioned 10-15 feet away from the screen.
Ambient light:
The level of ambient light in the room can also impact how many lumens you need. If the room is bright and sunny, you’ll need more lumens to ensure that the image is visible. On the other hand, if the room is dimly lit, you’ll need fewer lumens to achieve a bright and clear image. As a general rule, aim for at least 2,000 lumens if the room is brightly lit, and 1,000-1,500 lumens if the room is dimly lit.
Ultimately, the number of lumens you need will depend on your specific situation and needs. By considering these factors and following the guidelines provided, you can ensure that your presentations are bright and clear, even in daylight conditions.

Five things you can do to improve projection during the day
- Use a high lumen projector: As mentioned earlier, the number of lumens a projector has will directly impact how bright and clear the image appears. If you’re presenting in daylight conditions, it’s important to use a projector with a high lumen output to ensure that the image is visible.
- Use a screen with a high gain: A screen with a high gain is designed to reflect more light back towards the audience, which can help improve the visibility of the projected image. High gain screens are especially useful in brightly lit environments.
- Use a screen with a matte finish: Screens with a matte finish can help reduce glare, which can make it easier to see the projected image in daylight conditions.
- Use blackout curtains or blinds: If you don’t have control over the ambient light in the room, consider using blackout curtains or blinds to block out as much light as possible. This can help improve the visibility of the projected image.
- Use a brighter light source: If you’re using an LCD projector, you may be able to improve the visibility of the image by using a brighter light source, such as a high-intensity discharge (HID) lamp. Keep in mind that using a brighter light source may also increase the heat output of the projector, so be sure to use proper ventilation to prevent overheating.
Project Lumen Chart
Here is a projection lumen chart that provides a general guide for choosing the right lumen output based on screen size and ambient light conditions:
| Screen size (inches) | Brightly lit room (2,000+ lumens) | Dimly lit room (1,000-1,500 lumens) |
| Up to 80 | 1,000-2,000 lumens | 500-1,000 lumens |
| 80-100 | 2,000-3,000 lumens | 1,000-1,500 lumens |
| 100-120 | 3,000-4,000 lumens | 1,500-2,000 lumens |
| 120+ | 4,000+ lumens | 2,000+ lumens |
Keep in mind that these are just general guidelines and the actual lumen output you need may vary based on your specific situation and needs. It’s always a good idea to test the projector in the actual environment where it will be used to ensure that the image is bright and clear.
Conclusion
In conclusion, the number of lumens you need to project in daylight depends on a few different factors, including the size of the screen or surface you’ll be projecting onto, the distance between the projector and the screen, and the level of ambient light in the room.
By considering these factors and following the guidelines provided, you can ensure that your presentations are bright and clear, even in daylight conditions. It’s also a good idea to choose a projector with a high lumen output, use a screen with a high gain or matte finish, and consider using blackout curtains or blinds to reduce ambient light. With the right setup and a little bit of planning, you can successfully project in daylight and deliver presentations that are easy to see and understand.
