Fonts

Fonts are the baseline of your product’s voice. They decide whether your message feels professional, playful, or illegible. Choosing and applying them well keeps your product clear and consistent.

Why it matters

Fonts aren’t neutral—they carry personality. The same sentence can read friendly, clinical, or chaotic depending on typeface. It should fit your brand, but also the tone and circumstance of your message.

Key considerations

1. Readability: Choose fonts that stay clear at any size or weight, with strong contrast.
2. Consistency: Limit yourself to 1–2 families and use them consistently across the product.
3. Practicality: Make sure fonts are licensed, fast to load, and available across all platforms

Matching your message

Once your meet the basic criteria, the next step is determining the best fit.

If your content is serious - like dealing with health, money, or news, the less noticeable the better. If it’s distinctly light-hearted and low stakes, you can afford to add more personal touches.
