Design Tokens for Typography

What are Design Tokens?

Design tokens are the visual design atoms of the product's UI. They store design decisions, allowing for a consistent styling across platforms and products.

For typography, design tokens can include font sizes, weights, line heights, and letter spacing.

Importance of Typography Tokens

Typography tokens are crucial for:

• Maintaining design consistency across different platforms.
• Facilitating easy updates to typography styles.
• Improving collaboration between designers and developers.
• Enhancing scalability of design systems.

Defining Typography Tokens

Typography tokens can be defined in various formats including JSON, YAML, or CSS variables. Below is an example using JSON:

{
    "fontSizes": {
        "small": "12px",
        "medium": "16px",
        "large": "20px",
        "xLarge": "24px"
    },
    "fontWeights": {
        "regular": "400",
        "medium": "500",
        "bold": "700"
    },
    "lineHeights": {
        "normal": "1.5",
        "tight": "1.25",
        "loose": "1.75"
    }
}
                

Implementing Typography Tokens

Implementing typography tokens can vary based on the framework or library used. Below is an example using CSS variables:

:root {
    --font-size-small: 12px;
    --font-size-medium: 16px;
    --font-size-large: 20px;
    --font-weight-regular: 400;
    --line-height-normal: 1.5;
}

body {
    font-size: var(--font-size-medium);
    line-height: var(--line-height-normal);
}

h1 {
    font-size: var(--font-size-large);
    font-weight: var(--font-weight-bold);
}
                

Best Practices

To effectively utilize typography tokens, consider the following best practices:

1. Define a clear naming convention for tokens.
2. Group tokens logically (e.g., by type or usage).
3. Utilize variables to ensure easy access and updates.
4. Document tokens clearly for team accessibility.
