Frequently Asked Questions
What's the difference between system fonts and Google Fonts?
System fonts (Arial, Times New Roman, etc.) are pre-installed on most computers and load instantly with no downloads. Google Fonts require loading from Google's CDN but offer 1000+ professionally-designed typefaces with multiple weights and styles. Use system fonts for speed; use Google Fonts for design variety.
How do I know if a font weight is available?
Our tool displays only available weights for each font. If a font doesn't have 'Thin' or 'Black' weights, those options will be disabled. Google Fonts show all published weights; system fonts typically offer Normal and Bold. Some Google Fonts have 9+ weights for fine-grained typography control.
What is letter-spacing and when should I adjust it?
Letter-spacing (tracking) adjusts space between characters. Increase it for all-caps headings to improve readability. Decrease it slightly for condensed layouts. Body text usually needs 0 or minimal spacing. Negative spacing works for large headlines; positive spacing improves legibility in small caps or wide layouts.
How do I choose fonts that pair well together?
Pair contrasting fonts: serif with sans-serif, geometric with humanist. Ensure similar x-heights for visual harmony. Test headings and body text side-by-side using our comparison view. Good pairings: Open Sans + Merriweather, Montserrat + Lora, Roboto + Playfair Display. Avoid pairing fonts that are too similar.
Are Google Fonts free to use commercially?
Yes! All Google Fonts are open-source and free for personal and commercial use with no restrictions. You can embed them on websites, use in apps, or include in design projects without licensing fees. Some have SIL Open Font License, others Apache License—both allow commercial use.
What font size should I use for body text?
For web body text, 16px is the modern standard for optimal readability. Mobile devices often default to 16px; smaller text forces users to zoom. For print, 10-12pt works well. Headlines can range from 24px to 72px+ depending on hierarchy. Test your actual content at different sizes with our tool.
How does line-height affect readability?
Line-height (leading) affects text density and reading comfort. For body text, use 1.5-1.6x the font size (e.g., 24px line-height for 16px text). Shorter line-heights work for headlines; taller for long paragraphs. Narrow columns need less line-height; wide columns need more. Adjust with our slider to see the impact.
Can I test custom fonts not in Google Fonts?
Currently, the tool supports system fonts and Google's library. For custom fonts (Adobe Fonts, commercial typefaces), you can use browser developer tools to temporarily load them, then use our tool's spacing and size controls. Or test similar Google Fonts as proxies for custom fonts during planning.
