About Variable Font Tester
Test variable fonts with interactive axis sliders — choose from Google Fonts or upload your own, all in your browser.
How to use Variable Font Tester
- 1Select a variable font from the Google Fonts dropdown or upload your own (.ttf, .otf, .woff2).
- 2Adjust typography settings: font size, line height, letter spacing, text and background colors.
- 3Use the variation axis sliders (weight, width, slant, etc.) to explore the font's full range.
- 4Preview the result with the editable preview text.
- 5Copy the CSS output including font-variation-settings for use in your project.
Tips
- Variable fonts replace multiple static font files with one file — reducing HTTP requests and total file size.
- Not all axes are equal: weight (wght) is the most common, but check for width (wdth), optical size (opsz), and custom axes.
- Use font-variation-settings in CSS transitions for smooth animated typography effects.
