Crafting Typeface Systems for Web Interfaces

1. Finding Your Voice: How to Select and Pair Typefaces

Before we can even think about font sizes, we must first choose the typefaces themselves. This decision should be driven by brand strategy, not just visual preference. Your background in understanding business models will be an asset here, as we'll start by defining the brand's personality.

This process gives you a defensible rationale for your font choices—a key skill for communicating with clients. You're not just picking fonts you like; you're selecting typographic tools that align with a stated business and brand strategy.

2. Creating Harmony: Defining a Typographic Scale

Once you have your chosen typefaces (typically one for headings and one for body text), the next step is to create a set of predefined sizes. A typographic scale ensures that the size relationships between your headings, subheadings, and paragraphs are consistent and mathematically harmonious. This is analogous to establishing clear reporting hierarchies in a financial statement; every element has a defined level of importance.

There are two primary ways to approach this: using a modular scale ratio or using a more pragmatic, grid-based system.

The Modular Scale Approach

This method uses a starting base size (usually for your body text, e.g., 16px) and a ratio (e.g., 1.250) to calculate all other font sizes by multiplication or division.

Tools like type-scale.com (mentioned in the video "Create the Perfect Typography Scale" by Mizko) can quickly generate these scales for you. This is a great way to explore possibilities, but for our practical work, we will use a method that integrates more directly with the grid system you'll learn about in the next lesson.

The Grid-Aligned Approach

For UI design, it's often more practical to build a scale where font sizes and, crucially, line heights align with a base unit, like 8px. This ensures vertical rhythm and makes layout construction much easier.

We will now walk through building a scale using this method directly in Figma.

This method provides a robust foundation that not only looks good but also aligns perfectly with the structured layout systems used in web development.

3. Practical Exercise: Build Your Brand's Typographic System

Now it's time to apply this systematic approach to your own brand. You will select fonts and build a complete, reusable typographic scale in Figma.

Your Task:

1. Open Your Figma File: Navigate to the "Brand Foundation" page you created in the last lesson, where your color palette lives. You'll build your type system right alongside it.

2. Define and Select:

   • Based on your bespoke gifting business, write down 3-5 brand adjectives (e.g., "Handcrafted," "Elegant," "Personalized").
   • Choose two typefaces: one for headings and one for body text. A serif and sans-serif pairing is a classic choice. In a text box in Figma, write a brief sentence justifying why their letterforms and characteristics align with your brand adjectives. (e.g., "I chose Playfair Display for headings because its high-contrast strokes feel elegant, and Lato for body text because its open, friendly structure is highly legible and feels welcoming.")

3. Build Your Type Scale:

   • Following the method in the "Typography Scale and Line Height" video, create text layers for your full scale. A good starting set is:
     • Headings: H1, H2, H3, H4
     • Body: Body-Large, Body-Regular, Body-Small
     • Utility: Caption, Button
   • Set your Body-Regular text to a 16px font size and a 24px line height.
   • Define the sizes for the rest of your scale. You can use the values from the video as a starting point, but feel free to adjust.
   • Crucially, ensure every line-height you set is a multiple of 8.

4. Create and Organize Text Styles:

   • Convert each text element into a Figma Text Style.
   • Use a clear, hierarchical naming convention. For example:
     • Headings/H1
     • Headings/H2
     • Body/Regular
     • Body/Small
   • Apply your chosen heading font to the Heading styles and your body font to the Body styles.

By the end of this exercise, you will have a complete set of color and text styles in Figma, forming the core of a professional design system for your brand.

Conclusion

In this lesson, you've learned a structured, strategic process for building the typographic foundation of a user interface. You now know how to select and pair fonts based on brand identity and create a harmonious, hierarchical typographic scale that ensures consistency and readability. This systematic approach transforms typography from a purely aesthetic choice into a logical component of your design system.

Key Takeaways:

• Brand Drives Typography: Start by defining brand adjectives to guide your font selection.
• Pair for Contrast and Purpose: Often, a sans-serif for body text (legibility) and a serif for headings (character), or vice-versa, creates a versatile and professional pairing.
• A Scale Creates Harmony: Use a mathematical scale (based on a ratio or a grid unit) to define font sizes, ensuring visual consistency.
• Line Height is Key: For UI design, setting line heights to a multiple of a base unit (like 8px) is critical for creating vertical rhythm in your layouts.
• Use Figma Styles: Always save your typographic decisions as Text Styles for efficiency and scalability.

Preview of the Next Lesson:
Your work setting line heights to multiples of 8 has perfectly prepared you for our next topic. We will dive into the 8-point grid system, learning how to use it to structure a web page layout with precision and consistency. You will see how your color and type systems snap perfectly into this grid, creating a truly cohesive design.
