FAQ
What is Fontjoy used for?
Fontjoy is useful when you need to find fonts that work well together without testing hundreds of combinations manually. You can generate different pairings, lock a font you like, and continue exploring alternatives. It is particularly helpful for designers, marketers, developers, bloggers, and business owners creating websites, branding materials, presentations, or marketing content.
How does Fontjoy generate font pairings?
Fontjoy approaches font pairing as a compatibility problem and uses a neural network to recommend combinations. Instead of relying entirely on manual intuition, the tool analyzes relationships between typefaces and generates combinations designed to create both consistency and contrast. This speeds up experimentation when you are unsure which fonts naturally complement each other.
Can I lock a font in Fontjoy?
Yes. Fontjoy includes a Lock option that allows you to keep a font you already like while generating different combinations for the remaining fonts. This is especially useful when you have selected a primary brand or heading typeface but want to explore several complementary choices before deciding on the final typography system.
Can I manually choose fonts in Fontjoy?
Yes. Fontjoy provides an Edit option that lets you choose a font manually. This gives you more control when you already have a particular typeface in mind. You can combine your preferred selection with generated recommendations, making the tool useful for both entirely new typography ideas and projects with existing brand guidelines.
Can I preview my own text in Fontjoy?
Yes. Fontjoy allows the displayed text to be edited, so you can replace the sample copy with your company name, headline, or other content. This is useful because a font pairing can look different depending on the actual words, letter shapes, and visual length used in your design.
Who should use Fontjoy?
Fontjoy can be useful for anyone who needs complementary fonts but does not want to spend excessive time researching typography combinations. Web designers, graphic designers, developers, marketers, entrepreneurs, content creators, and students can use it to explore type combinations for websites, logos, presentations, social graphics, and other visual projects.
Is Fontjoy useful for website design?
Yes. Fontjoy can help website creators experiment with typography for headings, body copy, and other interface elements. By generating contrasting but related combinations, it can provide a starting point for a website's typographic hierarchy. Designers can then preview their own text and decide whether the selected combination fits the site's visual identity.
