How to Choose The Right Size For Your LED Display

In recent years, LED displays have become increasingly popular owing to their impact and versatility. The United States is the world’s largest advertising market. In 2021 alone, the country invested about $285 billion in promotional activities, a worthy splurge in the right direction!      

Unfortunately, many people have difficulty choosing the right size for their LED display. With the right size, you can maximize its impact and get great value for your money. 

Before making a decision, you should consider factors like the resolution, aspect ratio, viewing distance, and available space. If you are undecided on the LED screen size to buy, you’re in luck! We have put this article together as a guide for you. Read through, and you’ll get some useful tips.

How to Choose The Right Size For Your LED DisplayWhat Is an LED Display?

An LED display is an electronic device that creates visual displays using light-emitting diodes. LED displays are so rampant that you can find them in various industries, including transportation, sports, advertising, and entertainment, among others.

LED displays display visual content but differ from your home’s television screens. In reality, they are the elements behind the electronic billboards in the streets, the screens in a stadium, etc.

The main types of LED displays are monochrome LED displays and full-color displays. Monochrome LED displays only show one color, while a full-color LED display can display in various colors and graphics.

LED displays transmit visual content through different technologies, such as the following:

    • SMD LED technology is suitable for full-color displays as they are energy efficient while offering high brightness and resolution.
    • Through-hole Diodes technology is mostly used in monochrome displays as they can withstand outdoor environments and are more durable.
  • Chip-on-board COB technology is suitable for LED displays that require high brightness.

Factors to Consider When Choosing The Right Size For an LED Display

The display output you get depends on the LED screen size you choose. Here are the top parameters to bear in mind before deciding on the right size for your project:

1. Viewing Distance

The viewing distance is the space between the display screen and the person viewing the screen. This distance will not only help you determine the display size, but it will also help you get the best resolution for optimum viewing.

Viewing Distance

By calculating the viewing distance, you can ensure that the LED display is legible and visible. Generally, it is recommended that the distance from the display screen to the viewer should be at least 3 times the screen’s height. So an LED display that is ten feet high should have a viewing distance of at least thirty feet.

2. Resolution

The resolution simply describes the number of pixels on a screen. You can calculate a screen’s resolution using its width and height. Essentially, the resolution affects the details and clarity of the content displayed on the screen. 


A higher resolution will provide clearer images and text on your screen. Inadvertently, the LED screen size depends on the resolution and your desired viewing distance. Therefore, a smaller screen size will require a higher resolution for the content to remain legible even from a distance.

3. Aspect Ratio

The aspect ratio is the distance between the width and height of a display screen. It affects the quality of the content displayed on the screen and is an important factor to consider when choosing an LED screen size. 

Aspect Ratio

The most common aspect ratio for display screens is 16:9, similar to most television screens. When choosing a screen size, ensure that the aspect ratio suits the content you wish to display.

4. Space

Before purchasing an LED display, you must have determined the space where you hope to mount it. This way, you will know the range of LED screen sizes that can fit into your available space. You should also consider the viewing distance; all these factors will work together to determine the screen size.

If you have plans to mount an LED display in a busy area, you would have to invest in a large screen so that the screen remains visible to everyone. 

5. Pixel Pitch

Pixel pitch is the center-to-center distance from one pixel to another on an LED display, and it significantly affects the resolution and should influence your LED screen size choice.

Pixel pitch is measured in millimeters (mm). The smaller the pixel pitch, the closer a viewer can stand to the screen without seeing individual pixels and the higher the resolution. To calculate the pixel pitch, divide the distance between two pixels by the number of pixels in that distance.

For example, if the distance between two pixels is 20 mm and there are 200 pixels in that distance, the pixel pitch would be 0.1 mm. Pixel pitch is inversely proportional to the screen’s resolution, and a higher resolution will need a smaller pixel pitch for the content to be clear and easy to read.

Pixel Pitch

The pixel pitch can also determine the viewing distance for your LED screen. Generally, you can see what is on a screen at close range without seeing the individual pixels if it has a smaller pixel pitch. Certainly, a smaller pixel pitch will give you optimum viewing quality even with a small screen.

Smaller pixel pitches are preferable for indoor displays or displays that will be viewed up close. On the flip side, a larger pixel pitch is more suited for the outdoors or areas with a larger viewing audience.

Tips For Choosing the Right Size for Your LED Display

Now that you have properly understood LED screen sizes and the various factors that should influence your choice, we have put together a step-by-step guide on choosing the right size for your LED display:

1. Determine the Purpose of Your LED Display

Before you choose an LED screen size, you should be sure of what you need it for. Ask the relevant questions; will I use the screen for information display, advertising, or simply entertainment? 

The questions are important because the type of LED screens you need for out-of-home advertising is different from what you need for sports arenas, events centers, or learning environments. When you are certain of the purpose of your screen, you will easily determine the size that fits best.

2. Make Necessary Calculations

Don’t hurry to buy the next screen you see in the mall or online. Take time to calculate the viewing distance, resolution, aspect ratio, pitch pixel, and other relevant parameters that determine the screen’s output.

3. Set a Budget

Any decision you eventually take should be around your financial budget. While you may want an exquisitely looking display with an intimidating LED screen size, you shouldn’t blow up your coffers on it. If your desired screen size does not fit your budget, you may want to go back to the drawing table and review what you need.

4. Patronize Reputable Brands

When it comes to LED screens, quality should be your watchword. If you’re looking for sophisticated LED screen sizes and designs, you should patronize brands solely dedicated to creating excellent LED products. For instance, NSE LED Cloud is a renowned LED display screen manufacturer with a massive footprint in over 100 countries.

Its 6,000-square-meter manufacturing plant can handle any form of LED screen project. Apart from being a member of the prestigious AVIXA association, the company’s expertise and innovative prowess are further proven by its 26 groundbreaking patents in the audiovisual industry.


5. Consult a Professional

You may follow all the steps above and still have unsatisfactory results. This is because you are not exactly qualified or experienced enough to make the best LED display decisions. Working with a professional from the onset will help you avoid unnecessary mistakes and expenses as they will guide you through the process.


Choosing the right LED screen size is no walk in the park; you have to consider many factors to help you get the perfect LED screen to meet all of your viewing needs. The right LED screen size will effectively communicate to your audience while showcasing your product.
