How can I best find a happy medium to give a good exp

Answer 1

Out of experience, for the web i would say a width greater than 850 and less than 1000 px preferably in the 900's and a height of around 750 px, but bear in mind that the height would be variable in case of dynamic content. so the height could be set to 100% or auto. and best to align the website in the center, via the css property margin: 0 auto;
