Benefits of the Font Size Calculator

• Ensure readability across all devices and screen sizes.

What is the Ideal Font Size?

The ideal font size depends on your medium and audience. For web content, a base font size of 16px is recommended for body text, while headlines can range from 24px to 32px or larger, depending on their hierarchy.

For print materials, consider the viewing distance. Books typically use 10–12pt, while posters may require much larger sizes for readability from afar.

Responsive Font Sizes for Web Design

Responsive web design requires font sizes to adapt seamlessly to various screen sizes. Using scaling techniques like em, rem, or percentages can help achieve this. Our calculator simplifies the process by providing scalable size suggestions for different devices.
