Detailed Instructions

Summary

User interfaces should be dominated by content. Unfortunately, most of them are not. This tool is used to evaluate the percent pixels used by screen elements (screen real estate). Content should take up more than 50% of a screen.

This tool is based on a concept presented in Jakob Nielsen's book, Designing Web Usability: The Practice of Simplicity.
