Modular Scale Generator Typography Converter - Free Online

Modular scales are mathematical systems that ensure every design element—from font sizes to spacing—is proportionally related to others, preventing arbitrary choices. Our converter takes your foundational unit (often based on the golden ratio or a simple integer division) and instantly calculates all corresponding typographic values.

Instead of guessing that an H2 should be '36px' and a paragraph text should be '18px,' our tool generates these relationships systematically. For example, if you set your base unit at 4px, the converter might output values like 16px (H4), 24px (H3), 32px (H2), and 48px (H1). This guarantees harmonic consistency across all screen sizes.

Simply input your desired base number or the target size, select your scaling method (e.g., N=4 or Golden Ratio), and let our algorithm handle the complex calculations. We provide clear explanations so you understand not just the numbers, but why they work together.

Start by defining your content structure, not your sizes. Before using the converter, identify your key elements: H1, H2, Body, Caption. This will help you determine the necessary range of values.

• Establish a Strong Base Unit: Choose a base unit (e.g., 8px or 4px) that is a divisor of your target screen dimensions, making calculations cleaner and more divisible across different devices.
• Test with Real Content: Once you have generated the scale, copy-paste actual body text into your design mockups to see how the letter spacing and line height interact with the chosen type size.
• Prioritize Contrast: Use the converter's results to maximize the visual contrast between headings and body text. A large jump (e.g., 2x or 3x) is often necessary for clear hierarchy.

Remember that this tool provides the structure; your creative judgment determines the final aesthetic.
