What is the Typography Scale Calculator?
A typography scale calculator is an essential tool for designers and developers to create harmonious and consistent font sizes across their projects. It helps establish a visual hierarchy and ensures readability by generating a series of font sizes based on a chosen base size and a mathematical ratio. This tool simplifies the process of defining a modular type scale, making it easier to maintain a cohesive design system.
How it works
The Typography Scale Calculator operates on the principle of a modular scale, where each font size in the scale is derived from the previous one by multiplying or dividing by a constant ratio.
Base Size: You start by defining a base font size, typically the body text size (e.g., 16px).
Scale Ratio: Next, you select a scale ratio. Common ratios are derived from musical harmony and include options like Minor Second (1.067), Major Second (1.125), Minor Third (1.2), Major Third (1.25), Perfect Fourth (1.333), Augmented Fourth (1.414), Perfect Fifth (1.5), and Golden Ratio (1.618). This ratio determines the visual progression between font sizes.
Steps: Finally, you specify the number of steps. The calculator then generates a series of font sizes both above and below the base size, applying the chosen ratio iteratively. For example, if your base size is 16px and your ratio is 1.2, the next size up would be 16 * 1.2 = 19.2px, and the next size down would be 16 / 1.2 = 13.33px.
The tool then presents these calculated font sizes, often with the option to export them as CSS, making it easy to implement in your web projects.
Examples
Generate a Major Second Scale
Calculate font sizes using a base of 16px and a Major Second (1.125) ratio.
Golden Ratio Typography
Explore font sizes based on the aesthetic Golden Ratio (1.618) with a 20px base.

Why should I use a typography scale?
Using a typography scale ensures visual consistency, improves readability, and establishes a clear hierarchy in your designs. It helps create a professional and polished look by preventing arbitrary font size choices.
How do I choose the right base size?
How do I choose the right base size?
The base size is typically the font size of your body text. A common starting point is 16px, but it can vary depending on your design's overall aesthetic and target audience. Consider readability and accessibility when making this choice.
What are common scale ratios?
What are common scale ratios?
Common scale ratios are often derived from musical intervals and include Minor Second (1.067), Major Second (1.125), Minor Third (1.2), Major Third (1.25), Perfect Fourth (1.333), Augmented Fourth (1.414), Perfect Fifth (1.5), and the Golden Ratio (1.618). Each ratio produces a different visual rhythm and feel.
