App Description

People choose font sizes every day, yet seldom have a good reason for their choices. The Font Size calculator provides a simple yet powerful tool for making statistically-informed font-size decisions.

A Tool for Design: Enter viewing distance (in feet or meters) and the Font Size Calculator computes the minimum font size. Adjust this result based on lighting conditions and reliability.

A Tool for Analysis: Enter font size of an existing design (in points, inches or cm) and the Font Size calculator computes the maximum viewing distance. Adjust lighting conditions and reliability to determine the effectiveness of the design at different viewing distances.
