A typography scale is a structured set of font sizes created from a base size and a ratio. It defines how headings, subheadings, and body text relate to each other. A well built scale improves readability, balance, and visual hierarchy.
A typography scale calculator generates font sizes using mathematical ratios. It lets you preview text, control rounding, and export values in px and rem. This helps designers and developers create consistent typography without guesswork.
Start by entering the base font size. This is the default body text size used across your website.
Select a scale ratio to control how much each text level increases. Smaller ratios create subtle contrast, while larger ratios create stronger hierarchy.
