Choosing the right typography sets the foundation for readability, trust, and performance in your designs. When shoppers browse an online store, they scan prices, read product details, and look for checkout buttons. If the text is hard to read or feels unprofessional, they will leave. Using top Figma system fonts for e-commerce website prototypes ensures your design reflects how the site will actually perform in a browser, without relying on heavy custom web fonts that slow down load times.

What exactly are system fonts in Figma?

System fonts are typefaces pre-installed on operating systems like macOS, Windows, iOS, and Android. In Figma, you can call them using standard CSS font stacks, such as system-ui or -apple-system. Instead of forcing a browser to download a custom font file, the device simply uses the typeface it already has. This results in instant text rendering and a familiar reading experience for the user.

Which system fonts work best for online stores?

Not all system fonts are created equal when it comes to selling products. You need typefaces that offer excellent legibility at small sizes and clear hierarchy for pricing. Here are the most reliable options for your prototypes:

  • Inter: Designed specifically for computer screens, this font offers tall x-heights and open letterforms. It is highly legible and works perfectly for dense product grids and detailed descriptions.
  • Roboto: As the standard for Android and Google services, this typeface provides a clean, geometric structure. It handles numbers and currency symbols very well, making it ideal for price tags.
  • San Francisco: This is the default system font for Apple devices. Using it in your Figma file builds immediate visual trust for iOS shoppers, as it matches the native feel of their devices.
  • Segoe UI: The Windows default offers excellent readability on desktop monitors. It is a safe, professional choice for B2B e-commerce dashboards or large-scale retail stores.

When should you choose system fonts over custom typography?

You should default to system fonts during the early wireframing and prototyping phases. This allows you to focus on layout, spacing, and information hierarchy without getting distracted by aesthetic details. You should also stick to system fonts if your brand prioritizes page speed and accessibility over unique visual flair. If you are building a responsive store, you might also want to explore how to pair these fonts for different screen sizes to maintain consistency across devices.

What common typography mistakes hurt e-commerce conversions?

Designers often make avoidable errors when setting up text for online stores. One frequent mistake is using font weights that are too thin for price tags or discount badges, making them hard to read on bright phone screens. Another error is setting body text smaller than 16 pixels, which forces mobile users to zoom in. This is especially problematic if you are also designing companion apps, where strict mobile interface typography rules apply to ensure tap targets and text remain accessible.

How do you set up effective text styles in Figma?

To keep your prototype organized, build a dedicated typography scale in your Figma design system. Start by defining a base body size of 16 pixels with a line height of 1.5 for product descriptions. Set your primary headings to 24 or 32 pixels with a bolder weight to draw attention to product titles. In your text style settings, use a font family stack like system-ui, -apple-system, sans-serif to simulate real-world browser rendering. Finally, ensure your text maintains a high contrast ratio against the background, particularly for critical elements like "Add to Cart" buttons.

Your E-commerce Typography Checklist

Before handing your prototype off to developers or stakeholders, run through these practical steps:

  • Verify that all body text is at least 16 pixels in size.
  • Check that price numbers use a font weight of at least 500 (Medium) for clarity.
  • Ensure your Figma text styles use a native system font stack rather than a heavy custom download.
  • Test your prototype on an actual mobile device to confirm readability in natural lighting.
