Hello Dick, I have really enjoyed reading your articles and find your perspectives to suit my own taste. In this article you quote seating distances in relation to screen size and resolution. You also state that the basis of your calculations are from a BBC eye test.

I own and operate a small growing installation company and am always looking to improve the skills and service offered to my clients. Can you detail more information about your calculations i.e. how are they derived.

If I have not offended you with the request, I would like to build my own calculator as a tool to help in specifying screen size/resolution for clients.

Regards, Paul Horwood
