What size characters do I need?

With London Electronics displays, you have a wide choice of character heights for different viewing distances.

You should measure the maximum viewing distance you'll need, and use this chart to work out the ideal character size for you.

This will make sure you won't have to struggle to read the display. And, you won't pay too much for a display which is bigger than you need.
