Which Dot Pitch Is Best for Your LED Wall Display?

When your project requires an LED wall with the best clarity at an optimal viewing distance, you need to consider an LED solution with the best dot pitch for the desired display.

It is interesting how LED display technology has many technical terms that may be confusing. You could be wondering what a dot pitch is, and how it impacts your LED display. 

In this post we simply the terms and guide you on how to ensure that you choose the right pixel pitch for your target audiences.

Definition of Terms: Pixel and Dot Pitch

What is a Pixel?

A Pixel is the smallest digital unit of an image. It represents a specific image color with its level of brightness. They are formed by tiny dots. Therefore, the smallest part of an image is made of a group of dots called pixels. Clear? Good. 

Now, the larger the image or view area, the more pixel groups will represent the different parts of the image. 

To understand dot pitch, let’s now focus on two adjacent pixels with their respective dots. 

What is a Dot Pitch?

Imagine two adjacent pixels representing an image.  A Dot pitch, therefore, refers to the distance between two adjacent pixel dots. 

This is the same as the center distance between two adjacent pixels. A dot pitch is also referred to as a pixel pitch.  It is a small distance measured in millimeters.

The smaller the distance between the adjacent pixels or between two adjacent image dots, the more shaper and more detailed will be the image. 

It means the shorter your dot pitch or pixel pitch, the sharper will be your image display. Therefore, the quality of your LED display is determined by the dot pitch of your LED screen.

How Dot Pitch Affects Your LED Display

Your LED screen’s pixel pitch or dot pitch is directly linked to the quality and the brightness, or clarity of its displayed image. 

Therefore, the larger the dot pitch for your LED, the lesser will be its image sharpness and details. This means you will spend less on it. 

However, for an LED screen with a smaller pixel pitch, the image quality will be enhanced as the displayed image will be shaper with more visible details.  Ultimately, you will have to pay more for such an LED solution. 

So, how about if you want a larger screen with a higher resolution or smaller dot pitch? You will have to dig deeper into your pocket. But should this be the case, not necessarily. How? With a large screen display, viewers do not have to be viewing images at a closer distance. 

Therefore, the main focus should be on general image clarity when viewed from a distance. Image sharpness and details may only be more significant when viewing is at a close range.

In this case, if you have to go for large LED screens for long-distance viewing, a low-resolution or wide dot-pitch LED will still do the job, and you don’t have to break the bank! 

However, if your task requires very sharp images such as graphic design projects, an LED screen with a small dot pitch will be a perfect choice.  

Choosing The Best LED Dot Pitch – Terms You Need to Know

To fully understand and appreciate the importance of pixel pitch or LED dot pitch, here are some related terms that you should be familiar with and how they relate to each other. 

LED Resolution

LED screen resolution simply refers to the total number of pixels within your LED screen. 

Therefore, the larger the LED, the more pixels it has, so the higher its resolution. 

This also implies that the higher the resolution, the clearer will be the image details.  Just don’t forget that the clarity of your LED screen is also determined by other factors including your screen’s brightness.

Pixel Size

If you consider a single pixel and measure its dimensions, you get pixel size. This is usually expressed in micrometers. 

Even though pixel size is at times used when referring to pixel pitch, they are technically different.

If your LED screen has a higher pixel size, it means you have fewer pixels within a specific area, and, therefore, lower the resolution.

However, if your LED has a smaller pixel size, you have several pixels per inch of your screen meaning a high resolution.

Pixel Density

This refers to the concentration level of pixels per inch (ppi) of your LED screen. This simply means, that the higher the number of pixels per inch, the higher the resolutions, and so, the higher the image quality. 

Choosing The Best Types of Dot Pitch for Your LED Display

As you focus on choosing the best dot pitch specification for your LED screen, it is important that you first identify your application requirements.

Below are three 3 major types or categories of dot pitches you can choose from for a perfect indoor or outdoor video wall.

Regular Small Dot Pitch LED

If you are looking for an LED screen for indoor displays such as digital signage, or to install as video walls, then your best option is a regular dot-pitch LED solution. They come with a pixel pitch or dot pitch of not more than 5 mm.

Large Dot Pitch LED

Sometimes what your project needs is a wide outdoor LED for long-distance viewing such as billboards. In such instances, a wide dot pitch LED is your best choice. Pitch sizes for such LEDs can be in the range of 6mm to 10mm. 

Extra Wide Dot Pitch LED

For some outdoor applications such as live performance concerts or in large sports venues, you require an extremely large LED screen to reach as many target audiences as possible.  

In such a situation, LED screens with extra wide pitch sizes of over 10mm will be ideal and more economical. 

How Do You Evaluate Your LED Screen’s Dot Pitch?

To calculate your LED display’s pixel pitch or dot pitch, you must not use a microscope to physically take liner measurements. 

All you need is your LED screen’s diagonal measurement in millimeters and the specified display resolution. 

Equipped with these two parameters, visit any safe online pixel pitch calculator site such as omnicalculator. Simply fill in the required data and your screen’s pixel pitch measurement will be automatically calculated.

 A dot pitch or pixel pitch for an LED screen is represented by the letter P followed by a number. For example, a P5 LED screen has a dot pitch of 5mm, and a P10 LED Wall has a pixel pitch measuring 10mm.

Choosing The Best Dot Pitch for LED – Factors To Consider

To ensure that you make the right purchase decision, here are some key factors you should keep in mind when choosing the best pixel pitch for your video wall:

Your Application Needs

How you intend to use your LED screen will determine the best dot-pitch LED to go for. For tasks that require high-resolution displays such as software design or some professional applications, choose LED screens with smaller dot pitches. 

For other applications that do not require you to be very close to your screen such as enjoying movies on a large LED screen, or for indoor LED advertisements, a medium to large dot pitch screen will perfectly do the job.

Desired LED Screen Size

You must be clear about the LED screen size you need. To determine the right screen size, you must know the target number of viewers or the purpose of the LED screen. 

For instance, if you need to monitor several CCTV cameras, you will need large LED screens. 

So, the smaller the LED screens you need, the closer will be the viewing distance from the screen. This means, the smaller the dot pitch you ought to choose. 

Similarly, the larger the size of your LED screen, the further will be the viewing distance, and so, the larger the dot pitch or pixel pitch you need.

Viewing Distance From The LED Screen

This refers to the distance your viewers will feel comfortable when focusing on your video wall or LED Screen. 

If your target viewers’ optimal viewing distance is far from your LED wall, you do not have to spend on a high-resolution screen because viewers will not be so keen on image details. In this case, an LED screen with a high pixel pitch or dot pitch will save you money! 

Where optimal viewing distance has to be shorter, you need to consider an LED display with a smaller pixel pitch. This is because high-resolution images are desired.

Below is a table showing possible viewing distances and pixel pitches you should consider for your LED wall.

Minimum LED Viewing Distance (Feet) Optimal LED Viewing Distance(Feet) Most Suitable Dot Pitch(Millimeter)
2.95 6.56-9.84 0.90
3.94 6.56-9.84 1.20
4.92 9.84-16.40 1.50
8.20 16.40-26.25 2.50
16.40 32.8-49.21 5.00
32.80 65.62-98.43 10.00
131.23 262.47-328.1 40.00

Your Budget Limit

With many LED display options with different pixel pitches, you must only consider suitable solutions that are within your budget range. This will also help LED display experts or dealers recommend LED screens that are friendly to your budget. 

Conclusion

When choosing your best dot pitch for your video LED wall or other display applications, you must be aware of other related parameters that affect the display quality. These include your LED resolution, pixel sizes, pixel density, and LED size among others. 

Choosing the best dot pitch for your LED screen depends entirely on your application or project need. In case you are not sure about which solution to buy or options to consider, consult a reputable LED screen expert for professional guidance.
