Golden Ratio Type Typography Converter - Free Online

Our Golden Ratio Type Typography Converter utilizes the mathematical constant $\Phi$ (Phi), approximately 1.618, which represents a natural proportional relationship often found in visually pleasing compositions. Instead of relying on arbitrary scaling percentages, this tool applies the golden ratio sequence to your base font size.

When you input a primary headline size (e.g., 72pt), the converter instantly calculates all related typographic scales—such as subheadings (H2, H3) and body copy—by dividing or multiplying that base value by $\Phi$. This ensures that every element maintains an inherently harmonious relationship with the others.

For example, if your main title is 72pt, the tool will determine a perfect H2 size of approximately 44.5pt (72 / 1.618) and an optimal body copy size around 27.5pt. This systematic approach guarantees visual consistency across all screen sizes and print media.

To maximize the impact of your golden ratio type scale, remember that typography is a system. Don't just convert headline sizes; consider how line height (leading) interacts with them.

A general best practice is to set your body copy's leading at 1.5 times the font size, regardless of what our tool calculates for point size. This ensures optimal readability on long passages of text.

• Establish a Base: Start by setting your target body copy size first (e.g., 16px).
• Build Upwards: Use the converter to scale all other elements relative to that base, ensuring consistency across H1 through captions.
• Test on Multiple Devices: Always check your final output on various screen resolutions to confirm the ratios hold true in practice.
