Video Wall Pixel Pitch Calculator

 





Pixel pitch:
Visual acuity distance:

To use our video wall pixel pitch calculator, simply enter the distance the screen will be viewed from and click ‘calculate’.

The pixel pitch calculator will determine the pixel pitch of the video wall, which is the distance between pixels on the display, measured in millimeters and also the visual acuity distance which is the distance that someone would be able to see individual pixels This will give you an idea of the level of detail and clarity that the video wall will be able to display.

What is Visual Acuity Distance?

Visual acuity distance refers to the distance at which a viewer can discern the individual pixels on a display screen. For video walls, the visual acuity distance is determined by the size of the display screen, the resolution of the display, and the viewing distance of the viewer.

 

In general, the larger the display screen and the higher the resolution, the closer the viewer can be to the screen while still being able to not see individual pixels. The optimal visual acuity distance for a video wall will depend on the specific characteristics of the wall and the intended viewing conditions.

How Do You Calculate Visual Acuity Distance?

Visual Acuity Distance (in feet and inches) = (Resolution (in pixels per inch) x Viewing Distance (in inches)) / Display Width (in inches) / 12 inches/foot

Using this formula, you can convert the result from inches to feet and inches by dividing the number of inches by 12 inches/foot.

For example, using the same values as in the previous example (a display screen with a resolution of 100 pixels per inch, a width of 50 inches, and a viewing distance of 50 inches), the visual acuity distance would be calculated as follows:

Visual Acuity Distance (in feet and inches) = (100 pixels/inch x 50 inches) / 50 inches / 12 inches/foot = 8.333 feet

This means that the viewer would need to be at least 8 feet and 4 inches away from the screen in order to discern the individual pixels on the display.

What is the Average Comfortable Viewing Distance?

The average comfortable viewing distance for a video wall or other display screen will depend on a variety of factors, including the size of the display, the resolution of the display, the ambient lighting conditions, and the preferences of the viewer. In general, viewers tend to prefer a slightly longer viewing distance for larger displays, as this allows them to take in the entire display without having to move their head too much.

As a rough guide, for a standard 1080p high-definition display with a diagonal screen size of 40 inches, a comfortable viewing distance might be around 8-12 feet. For a 4K ultra-high-definition display with the same screen size, a comfortable viewing distance might be closer to 6-9 feet.

It’s worth noting that these are just rough estimates, and the optimal viewing distance will ultimately depend on the specific circumstances and preferences of the viewer. Some people may prefer a longer viewing distance, while others may prefer to sit closer to the screen.

Below are a range of rough estimates of average comfortable viewing distances based on pixel pitch and display size. Please note that these are just rough estimates, and the actual comfortable viewing distance may vary depending on the specific circumstances and preferences of the viewer.

Pixel Pitch (mm)Average Comfortable Viewing Distance (feet)
0.62.5-5.25
1.03.5-6.75
1.54.5-9.75
2.05.5-11.25
3.08.5-18.75
4.011.5-24.75
5.013.5-30.75
6.015.5-35.75
8.020.5-45.75
10.025.5-56.25

What Is Pixel Pitch And Why Is It Important?

Pixel pitch is also an important factor to consider when selecting a video wall. In a video wall, a smaller pixel pitch can result in a more detailed and higher resolution image, which is generally desirable for applications such as digital signage, command and control centers, and other situations where the display will be viewed from a close distance.

However, it is worth noting that smaller pixel pitch also typically means that the individual monitors or screens in the video wall will be more expensive, and the overall cost of the video wall may be higher as a result. Additionally, the distance at which the video wall will be viewed can also impact the optimal pixel pitch. In general, a video wall that will be viewed from a closer distance will require a smaller pixel pitch in order to achieve a clear and detailed image, while a video wall that will be viewed from a greater distance can often use a larger pixel pitch.

When the display will be viewed from a greater distance

A larger pixel pitch can be acceptable for display devices that will be viewed from a greater distance, as the pixels will appear smaller and less noticeable to the viewer. For example, a TV with a larger pixel pitch may be acceptable for use in a living room where it will be viewed from a couch, but may not be as suitable for use as a computer monitor that will be viewed from a closer distance.

When cost is a major factor

As mentioned earlier, smaller pixel pitch typically means that the individual monitors or screens in a video wall will be more expensive. If cost is a major concern, a larger pixel pitch may be a more economical choice.

When the display will be used for text-based content

A larger pixel pitch can sometimes be more suitable for displays that will be used primarily for displaying text-based content, as the individual pixels may be less noticeable and the text may appear more crisp and legible.

 

It is worth noting, however, that a larger pixel pitch will generally result in a lower resolution and less detailed image, so it is important to carefully consider the intended use of the display and the trade-offs involved when deciding on an appropriate pixel pitch.
