How to choose the size of a teaching all-in-one device? Three steps to find the best solution

When choosing a teaching all-in-one machine for the classroom, size is crucial. If it's too small, the students at the back won't be able to see clearly; if it's too large, not only will it waste the budget, but the students at the front won't have a comfortable viewing experience either. In fact, choosing the size is not complicated. Just follow these three core points. 

I. Observe the Scenarios: Different Spaces, Different Choices 

Small spaces: such as kindergartens and group counseling rooms, it is recommended to choose a size of 55-65 inches. The appropriate size is suitable for children's height, providing a better interactive experience. 

Standard Classroom: This is the most common requirement, covering regular classrooms in primary and secondary schools, universities, and training rooms. A size of 75-86 inches is considered the ideal dimension, ensuring that each student can see clearly at a viewing distance of 4-7 meters. 

Large spaces: such as lecture halls and auditoriums, require a screen size of 90 inches or larger to ensure clear viewing from a distance and to guarantee that the content is easily visible. 

II. Determine Distance: A Simple Formula for Easy Judgment 

A simple rule is: "The distance from the farthest student's seat should be between 3 to 6 times the height of the screen." 

For instance, if an 86-inch all-in-one monitor is about 1.1 meters in height, then the maximum viewing distance should not exceed 6.6 meters. 

You can measure the length of the classroom in advance and use this formula to quickly calculate the range of the required screen size. 

III. Observe the Crowd: Age Determines Experience 

Young students: Young children and primary school students have limited height, and overly large screens can actually cause eye strain from looking up. A screen size of 65-75 inches is usually a more comfortable and safe option. 

Senior students and adults: They can interact more effectively with large screens. Screens of 86 inches and above provide more space for writing and presentation, suitable for efficient classrooms and collaboration. 

Based on the size of your classroom, the maximum viewing distance and the age of your students, you can make a reasonable choice.
