How to Use This Tool
Open FontBase in your browser and browse or search for the fonts you want to preview from the available library.
Click on a font to select it, then type your own custom text in the 'Preview Text' box to see how the font renders.
Adjust the size slider and weight dropdown (or variable font axes) to match your design requirements.
Add multiple fonts to the comparison view by clicking the comparison icon, then toggle between them or view them side-by-side with identical settings.
Finalize your selection and copy the font name, CSS import, or export your comparison for reference.
What Is FontBase?
FontBase is a free web tool that lets you preview, compare, and test fonts before using them in your design projects. Instead of relying on static samples or guessing how a typeface will look at different sizes and weights, FontBase gives you interactive control: you type your own text, choose the font family, adjust the size, and play with weight settings—all in real time. This matters because choosing the right font can make or break a design’s readability, tone, and visual hierarchy. With FontBase, designers and non-designers alike can confidently select typography that fits their brand, web project, or print layout without wasting time or money on unsuitable fonts.
Formula
Font Appearance = (Custom Text Content) × (Font Family) × (Size in px or rem) × (Weight value). FontBase applies this combination using CSS font properties: it loads each selected font and renders your text with the specified size (via font-size) and weight (via font-weight or variable font axes). The tool then displays the results side‑by‑side so you can instantly compare how each font handles the same parameters. In plain English: the appearance you see is exactly how the font will look in your final project, because FontBase uses the same rendering engine as the browser or design software you are building for.
Tips for Best Results
🔤 Always test with your actual content — a headline, a paragraph, or even code — because different letters and numbers can reveal spacing issues or missing glyphs.
📏 Try extreme sizes: test at both very small (10px) and very large (72px) to catch readability problems and ornamental details.
⚖️ Compare at least two weights (e.g., Regular vs. Bold) to see how the font’s overall character changes; some fonts lose personality when bolded.
🔄 Save your favorite pairings by taking a screenshot or using FontBase’s bookmark feature — this speeds up future design decisions.
Frequently Asked Questions
Can I upload my own fonts to FontBase?
FontBase works primarily with system-installed fonts and a curated library of web fonts. You cannot upload custom font files directly, but you can preview any font already on your system by selecting it from the list.
How do I compare multiple fonts side by side?
After selecting a font, click the 'Add to Comparison' button (usually a plus or split icon). Repeat for other fonts. FontBase will display them simultaneously with the same text, size, and weight settings so you can evaluate them in one glance.
Does FontBase support variable fonts?
Yes — if the font is a variable font and your browser supports it, you’ll see a slider for weight, width, or other axes. This lets you fine‑tune the appearance beyond standard predefined weights.
