Best Fonts for a Link in Bio Page: Choosing for Small Screens

The best fonts for link in bio pages are simply the ones people can read quickly on a phone while walking down the street. Personality matters too, but only after readability. For most pages, a clean sans serif is the safe choice, and a serif can work well if you want a more editorial feel. Decorative fonts are best avoided for anything people need to read.

This is a small decision, so don’t spend too long on it. Here’s how to get it right quickly.

What matters on a small screen

On a phone, a font has less room to work, and it may be viewed in poor conditions. Look for:

• Clear letter shapes. Can you easily tell apart an I, an l and a 1?
• Open spacing. Tight letters blur together at small sizes.
• A sturdy weight. Very thin fonts can vanish on a low-quality screen or in sunlight.
• Fast loading. A page that shows text immediately beats a pretty one that takes a moment.

Test any font at the actual size it’ll appear, on a real phone.

Serif, sans serif and monospace

Modern screens handle serif fonts much better than old ones did, so a serif isn’t automatically harder to read on a phone. Still, a heavily styled font can slow people down, and speed matters on a page like this.

Matching tone to font

Think about what your business sounds like when it’s speaking to a customer.

Your font is only one signal among many. Your words, photos and colours contribute much more. A clear page in a plain font will always beat a confusing page in a beautiful one.

The four BioFlow options

BioFlow offers four typefaces in its appearance settings, plus a “Theme default” option that uses whatever your theme specifies. You can’t upload a custom font.

Plus Jakarta Sans

A modern sans serif that’s clean and friendly. It’s a good default for creators, small businesses and most other pages.

System

Shown as “System UI”, this uses the phone’s own interface font, so your page looks at home on the device. It’s a practical, no-fuss choice, and it’ll look slightly different on an iPhone than on an Android phone.

Georgia

Georgia is a classic serif designed for reading on screens. It suits writers, consultants, editors and anyone wanting a more considered tone.

IBM Plex Mono

A monospace font with a technical feel. It suits developers, designers and brands that want something distinctive. Long text in monospace takes more space and can feel heavy, so keep your labels short if you choose it, and check how they fit on a phone.

Size, weight and contrast

A good font can still fail if it’s poorly displayed. On a platform where you can’t set exact sizes, your job is mainly to check rather than control.

• Check long labels on a small phone. Do they wrap awkwardly, or get cut off?
• Read it at low brightness. If you strain, your visitors will too.
• Check text over images and gradients. This is where readability usually breaks down.
• Check contrast. WCAG 2.2 asks for at least 4.5:1 for normal text. Our guide to accessible pages explains what that means in practice. BioFlow’s appearance settings include a contrast check, which gives warnings.
• Keep button text short. Shorter labels look better in any font.

Your colour choices directly affect how readable your font is, so look at your colour scheme together with this.

When to keep it simple

Often, the best choice is to change nothing. Your theme already has a typeface that goes with its colours, so keep it unless you have a reason to change. That’s particularly true if you’re choosing between similar sans serif fonts, a difference few visitors would notice.

Change it if your brand already uses a clear type style, if the default feels wrong for your audience, or if you’re finding it hard to read. Otherwise, spend your time on labels, order and content. Choosing a theme gives you a coherent starting point, and the wider design best practices cover what matters more.

FAQ

What font is best on mobile?

A clean sans serif with clear letter shapes and a solid weight is the safest choice, as it stays readable at small sizes. Well-made serif fonts also work on modern screens. Avoid thin, decorative or script fonts for anything people need to read. Always test on a real phone.

Can I upload a custom font?

Not on BioFlow. You can choose from Plus Jakarta Sans, System UI, Georgia and IBM Plex Mono, or use your theme’s default. Other tools vary, with some offering custom fonts on certain plans. If your brand font matters, you can use it inside images such as your logo.

Does font choice affect clicks?

We’re not aware of reliable evidence that a particular font increases clicks on link pages. Readability can certainly affect whether people understand your page, so a hard-to-read font could cost you. Beyond that, your wording, order and offer are likely to matter far more.
