Nits Brightness–Know the Correct Brightness for LED Display

With increasingly more modern life depending on technology with display, it is best to ensure the safety of eyes by keeping track of the brightness of our screens. That is where knowledge on Nits brightness comes in.

What is Nits Brightness?

Nits is a unit for measuring brightness. It measures the level of brightness perceived by the eye from one screen. One Nits is the equivalent of one candela per square meter. Candela is a unit for measuring the intensity of light. Therefore, Nits of brightness is a measure of the intensity of light for every square meter.

Measurement Units for Screen Brightness

The screen brightness depends on a variety of factors such as the sum of all pixels, amount of lumen, and pixel pitch.

All these factors help to determine the overall brightness of the screen. Light intensity measured using candela per meter square can help determine Nits. Therefore 1 Nit is equal to 1cd/m2.

Comparing Nits Brightness and Lumen in LED Screens

Lumens is a unit used to measure the degree of light emitted by a device. It measures the amount of visible light produced. Nits on the other hand is a measure of how bright a display appears to the viewer.

Lumens focuses on the intensity of the light from the source while Nits focus on the light perceived from the source by the viewer.

Measuring Nits on Brightness on Display Screens

Typically, you can know the Nits of your devices without needing to measure them yourself. Manufacturers usually include the Nits of your display brightness. This information can also be online through the websites of the respective manufacturers.

In the absence of this information, some devices can be used to measure the Nits of your display screen. The digital lux meter is an example of these devices. It measures in lux. One Nit is the equivalent of 3.14159 lux. If you do not want to purchase a device for this purpose you can also download software on your device. The software is programmed to calculate the Nits of your display. Some applications are programmed for this purpose.

Importance of Knowing LED Nits Brightness

There are several benefits to knowing LED Nits brightness. It can help you when selecting a display.

Nits should be considered when purchasing a display. It will ensure that you get a display that will be perfectly suited to your needs.

Nits helps us preempt the power consumption rate of a device even before purchasing it. The brighter the display the more power it is likely to consume. Understanding this will ensure that you make an informed decision during your purchase.

It is therefore important to know the LED brightness as you purchase your device as it will also help you understand the limitations of your device in terms of lighting and utilization.

Recommended Nits Brightness for Screens

Different display screens have different Nit brightness. The ideal brightness also depends on the type of environment you are in.

While outdoors during the day when there is plenty of ambient light a brighter screen is more practical.  If your outdoor display screen setup is mainly outdoors, then a range of 3000 to 7000 Nits is recommended. For indoor settings, that are typically shaded with limited ambient light a dimmer screen is ideal. For this type of setting the recommended Nits is 1000 to 1500 Nits.

The recommended level of brightness may also depend on the type of device you have.  For example, for smartphones, the recommended level is 300 to 1,500 Nits. The recommended level for laptops ranges from 200 to 600 Nits and for monitors is from 100 to 500 Nits. Smartphones have a wider range as they are used both outdoors and indoors.

How Nits Brightness Affects LED Screen Users

Overexposure to extremely bright screens for a prolonged time may lead to eye strain, tension headaches as well and other eye complications. This is also the case for very dim screens that require straining to properly see the contents displayed on the screen.

The attention and alertness of a viewer can also be influenced by the brightness of the screen. This is why you should consider the Nits of a display when purchasing a device.


Nits brightness is not one of the main factors considered when purchasing devices. Even though it is often overlooked it is important as it impacts functions such as power consumption. Most devices are programmed with a range of Nits of brightness to allow you to adjust accordingly.
