How To Choose the Best Display Size for a Conference Room or Classroom

How do you choose the right size display for a classroom? Or how do you choose the right TV size for a conference room? These are deceptively simple questions with surprisingly complex answers. In fact, there is quite a bit of science, math, and geometry behind answering these types of questions.

It is so complex in some cases that the audiovisual industry has created a set of calculators to help simplify the various equations used in determining things like the ideal screen size, mounting height, or viewing distance. Even then, we feel that these calculators have a steep learning curve and require the taking of too many measurements to help you confidently buy.

A simple guide to choosing the right display for a standard room

To eliminate the complexity, we have assembled this helpful guide to help ease the buying process for the standard conference room or classroom.

What size screen should I buy for a conference room or classroom?

The distance of the farthest viewer Ideal display size
27 feet or less 55 inches
27-32 feet 65 inches
32-37 feet 75 inches
37-43 feet 86 inches
Greater than 43 feet Consider a video wall

What is the closest distance a viewer should sit to the screen?

To ensure an ergonomic conference room design and to avoid unnecessary eye strain, the simple rule of thumb is that the closest viewer should sit no closer to the screen than the width of the screen. For example, if you had a 48-inch wide display, the closest person should sit no closer than 48 inches to it.

How high do I mount the screen on the conference room wall?

The best way to determine how high to mount your display on the wall is to measure the average height of your viewer’s eyes and mount your display no lower than that height. For example, if the average eye height of a seated viewer is 40 inches, you would want the bottom of your display to be mounted no lower than 40 inches.

Does the need to view precise details on screen change the size recommendations?

Yes! If your organization requires you to display and analyze precise details on the screen, such as architectural drawings or medical images, then you will want to decrease the distance of the farthest viewer significantly for each particular screen size. This will ensure that you achieve the proper level of clarity.

Again, we would recommend contacting one of our experts to determine the right fit for your particular needs, but the following chart gives some general guidance on how much to reduce the distance of the farthest viewer for each display. Please note that these distances will likely vary depending on your specific needs.

The distance of the farthest viewer Ideal display size
14 feet or less 55 inches
15-16 feet 65 inches
17-19feet 75 inches
20-22 feet 86 inches
Greater than 22 feet Consider a video wall
