Nits Brightness 101: How to Measure and How Much is the Best?


Brightness is a crucial factor to consider when purchasing electronic devices. Whether it's a smartphone, laptop, or television, the brightness level determines the quality of the display. When talking about brightness, one essential term to understand is "nits." In this article, we will delve into the concept of nits and explore how to measure it accurately. Additionally, we will discuss the ideal brightness level for different devices. So, let's dive into the world of nits brightness!

Understanding Nits:

Nits, also known as candela per square meter (cd/m²), is the measurement unit for brightness. It quantifies the intensity of light emitted by a display area. To put it simply, nits determine how bright a device's screen can be. The higher the number of nits, the brighter the screen will appear. Manufacturers usually list the nits value in the device specifications, allowing consumers to compare and make informed decisions.

Measuring Nits:

Accurate measurement of nits requires specialized equipment known as a spectroradiometer. This device measures the spectral power distribution of light emitted by a display and calculates the nits value. However, as a consumer, you may not have a spectroradiometer readily available. In such cases, you can rely on professional reviews or online resources that provide nits measurements for popular devices.

Factors Affecting Nits Brightness:

Several factors impact the brightness level of a device. Understanding these factors will help you make an informed decision when purchasing electronic devices. Let's explore the most significant factors:

1. Display Type:

Different display technologies, such as LCD, LED, OLED, and AMOLED, have varying levels of brightness capabilities. OLED and AMOLED displays tend to offer higher brightness levels compared to LCD or LED displays. It is worth noting that newer generations of these technologies often exhibit improved brightness capabilities.

2. Power Source:

The brightness of a device's screen can fluctuate depending on the power source. When running on battery, devices often have preset brightness limitations to conserve power. However, when connected to a power outlet, the brightness capability might increase considerably.

3. Ambient Lighting Conditions:

The surrounding environment plays a vital role in perceiving the screen brightness. If you typically use your device in brighter environments, choose a device with higher nits capability to ensure optimal readability. On the other hand, if you primarily use your device in dimly lit rooms, lower nits might suffice.

4. Screen Size:

The larger the screen size, the more challenging it is to achieve high brightness levels uniformly across the entire display area. Therefore, larger devices might have lower nit values compared to smaller ones. Consider the device's intended use and the viewing distance to determine the optimum size and nit level for your needs.

5. Indoor vs. Outdoor Use:

If you plan to use a device predominantly outdoors, it is essential to opt for one with high nits brightness. Outdoor environments are often filled with abundant natural light, which can diminish the visibility of screens with lower brightness capabilities.

Ideal Nits Brightness Levels:

Now that you understand nits and the factors influencing brightness, it's time to explore the ideal nits levels for various devices:

1. Smartphones and Tablets:

For indoor use, a smartphone or tablet with 400-600 nits is usually sufficient. This range allows comfortable reading and usage without straining your eyes. However, if you frequently use your device outdoors, it is advisable to opt for a device with a brightness capability in the range of 800-1000 nits for better visibility under bright sunlight.

2. Laptops and Monitors:

For laptops and monitors primarily used indoors, a brightness level of 250-350 nits is typically acceptable. This range provides a comfortable viewing experience without causing eye fatigue. However, if you work in brightly lit environments or require accurate color representation, choosing a display with higher nits (400-500 nits) is recommended.

3. Televisions:

Television brightness requirements depend on the viewing environment and distance. For dark room viewing, a television with 800-1000 nits will deliver an immersive and vibrant viewing experience. However, if your television will be primarily used in brightly lit rooms, a higher nits range of 1000-2000 will ensure clarity and visibility.

4. Gaming Consoles and HDR Content:

HDR content demands higher brightness levels to showcase the full depth of colors and details. When it comes to gaming consoles or HDR-compatible displays, look for devices with a brightness capability of 1000 nits or more. This range allows you to experience the stunning visuals intended by game developers and content creators.


Understanding nits brightness and its significance when purchasing electronic devices is essential. By familiarizing yourself with the factors influencing nits levels and the ideal brightness range for different devices, you can make an informed decision that aligns with your needs. Remember to consider display type, power source, ambient lighting conditions, screen size, and intended usage to determine the optimum nits brightness level for your device. Whether it's a smartphone, laptop, monitor, or television, finding the right balance of brightness will enhance your overall viewing experience.
