K-Pop Font Ratio

Calculate font-size ratios (A:B), scale factor, and percent difference with a K-pop inspired UI.

K-Pop Font Ratio is a lightweight Chrome extension designed to help designers, developers, and content creators quickly calculate font-size relationships. By entering two font sizes, users can instantly see the ratio between them, a simplified ratio, the scale factor needed to resize text, and the percentage difference. The extension supports common font size formats such as plain numbers, px, rem, em, and pt. All calculations are performed locally inside the browser, with no data collection and no external connections. The interface is intentionally simple and visually inspired by modern K-pop aesthetics, combining clarity with an engaging neon-style design. This tool is ideal for typography checks, responsive design planning, UI consistency, and quick comparisons between heading and body text sizes. It opens instantly from the Chrome toolbar and requires no setup, accounts, or permissions.
