What is Nits Brightness, And Why is It Essential?

Do you ever wonder why the elements of your smartphone screen may be seen even on a sunny day? That is what your device’s nits are for. Even if you possess at least one tablet or smartphone, you may be unaware of nits and the technical lingo that comes with them.

For instance, if you want to buy a television, you need to be aware of Nits. Nit is a common phrase in current television. Previously, there were no words for nits and lumens. However, with modern TVs (such as LEDs and LCDs). Nit is the most essential factor and today we are going to deep dive into this subject.

What are Nits?

NIT is a measure for measuring luminance or the amount of light emitted by an item. It is derived from the Latin word nitere, which means “to shine.”

NIT is comparable to Candela (cd/m2) but is not a unit of measurement in the International System of Units (abbreviated SI, from Systeme International, in French).

One nit is the quantity of light that a square meter receives. As a result, a “nit” is another method of representing brightness of 1cd/m2 (candela per square meter). Nits are crucial since they let us use our phones outside.

Do Nits Matter?

Nit’s brightness is important, but they are only one consideration in determining the best screen to use. Unless you want a specific brightness level for outdoor use or HDR. Screen quality is also determined by black levels, contrast ratios, resolution, sRGB, and other things.

What’s crucial is understanding a device’s low, medium, and high nit values so you can make an informed purchasing decision, especially if you’re searching for the best budget gaming monitor and want to ensure you’re getting a decent deal. Even if you choose the greatest choice, you may still encounter issues while gaming, such as the second monitor becoming black.

What is the Significance of Nits?

The simple version is that it refers to a unit of brightness. Lots of nits = lots of brightness, which improves the image’s appearance in a bright setting or with HDR TV shows and movies.

Nits are significant, but they should not be the decisive factor in your screen purchase unless you require something with a higher degree of brightness for HDR or outdoor use.

How Visible is a Nit?

As a general rule, an LED screen outputting more than 5000 nits is required for an outdoor display to seem brightly in bright sunshine. A high-quality LED panel may emit 10,000 nits or more.

A nit’s brightness is equal to the light provided by one lighted whale oil candle. Place a lit candle in a container that measures one meter on all sides, and the light that reaches the container’s surface is equal to one candela per square meter.

So, one candela per square meter corresponds to the light produced by a single lighted whale oil candle put in a one-meter by one-meter container. By placing another burning whale oil candle in the same container, you may get the equivalent of two candelas per square meter.

How Do You Determine the Brightness of Nits?

You may usually obtain information about your device’s nits by searching for its product specs on its manufacturer’s official website, sheet specifications, and so on. Detailed product reviews may also show how much nits certain item costs. Alternatively, you may utilize accessible applications or software to assist you to determine the nits brightness of your smartphone.

You can get TV brightness readings in nits (cd/m2, or candela per square meter) or foot-lamberts using less complex (and less costly) testing equipment (ft-L). So, if the instrument you’re using to measure light output gives you values in cd/m2, you’ll have your nits measurement.

If you don’t want to download software or applications only to find out, you may also use tools to assist you. A digital lux meter might be a useful tool for the work. After determining your device’s lux level, just perform the appropriate mathematics to determine the nits brightness of your device’s display.


Nowadays, considering the nits brightness of a screen display is critical, especially for smartphones and other handheld or portable devices. After all, you’re more likely to use your smartphone outside than your living room television. That being said, if you find yourself unable to use your smartphone on a sunny day despite turning up the brightness to maximum, it may be time to “nit”-pick the next phone you buy based on the number of nits it offers.
