How to be strategic when picking a typeface
Briefly

The article provides an in-depth look at essential typography metrics, particularly focusing on x-height ratio, visual arc, and their implications for legibility and design efficiency in user interfaces. A higher x-height can make text easier to read, especially on digital screens. The significance of visual arc in determining readable text size is highlighted, suggesting that optimal angles improve reading speed. The piece also recommends tools like the x-height Readability Calculator for evaluating font efficiency in relation to screen resolution and viewing distance, catering primarily to mobile designs.
The x-height of fonts plays a crucial role in legibility, particularly for digital interfaces, where higher x-heights enhance readability by making characters appear larger.
