To determine the optimal display there are various factors taken into consideration such as the viewing distance, resolution, and human visual acuity. There’s a specific formula that is used to calculate optimal display. You can use a diagonal screen size calculator to calculate the diagonal.


As per Avixa standard – Display Image Size for 2D Content (DISCAS), the Diagonal Size (D) of the display is calculated using:

D = sqrt(W^2 + H^2)

W = AR * Image Height

H = L/Discas Constant * Image Height


In this formula

D: Diagonal Size of Display

W: Width of Display

H: Height of Display

AR: Aspect Ratio

L: Distance of last viewing person

Yes, you can head to the XTEN-AV online screen size calculator that will guide you to select the best screen according to your inputs. However, you can also check out the same for multiple screens such as screens on the side and front walls.

All devices with screens employ an aspect ratio, which is the proportion between the height and breadth of a rectangular display. The ratio between a screen’s height and breadth is what is indicated by an aspect ratio screen size calculator rather than the size of the screen itself.

Yes, a sophisticated screen size distance calculator can take into account different viewing distances and room orientations. By allowing users to input their desired viewing distance and providing options to specify room dimensions and orientations, the screen dimensions calculator can consider these factors in its calculations to determine the optimal display size for a personalized and adaptable viewing experience.

Source resolution determines the level of detail and clarity that needs to be displayed. A higher resolution will require a larger screen to fully appreciate the finer details. Whereas lower resolutions might not be able to utilize the full potential of a large screen resulting in pixelated images.
