How do you choose the best image size for your audience?

Whether you are setting up a new meeting room in your office or classroom in a school, one of the first things you need to consider when planning the layout of the space is:

How big does the picture need to be, so that everybody in the room can clearly see the content?

That’s a very good question and not one that everybody will instantly know the answer to. Epson have done a lot of research into this.  This is because they want their customers to get it right first time.

Particularly in Education, achieving the optimum image size with the correct visibility, is critical for both teachers and students to get the most of every lesson with vibrant easy to read on-screen content.

It all starts with finding the right screen size for your room. This simple choice is so important – you need to display content clearly to have engaging lessons, whilst ensuring that you adhere to health and safety standards. 

You wouldn’t be comfortable working at your desk where the screen is too small – it’s not good for your eyes, and can compromise the quality of on-screen content.  For the same reason, you need an image size that is correct for your teaching space and audience, so it’s extremely important that you provide the same desktop display experience* even from the back of the room.


Achieving the optimal screen size means replicating the average desktop experience for all students in your class - including those furthest away from the screen. According to the Snellen eye sight test, to make an image appear the same size when it is twice as far away, it needs to be twice as tall, or four times the size in area.
