Feature Request: Support Percentage Values for Line Height in Figma Variables

Problem
 

Currently, Figma Number Variables do not support percentage values for line height. This makes it difficult to create a consistent and scalable typography system using variables.

Many designers prefer to define line height as a percentage relative to font size rather than using fixed pixel values. For example, a heading might use 125% line height, while body text might use 150%.
 

Suggested Improvement
 

Please add support for percentage values in Number Variables, especially for typography properties such as line height.

This would allow designers to create reusable variables like:

• line-height/tight — 120%
• line-height/normal — 140%
• line-height/relaxed — 150%

Designers could then apply these variables directly to text styles and maintain consistent typography across their design systems.

Benefits

• More flexible and scalable typography systems.
• Easier consistency between font size and line height.
• Better support for design tokens and design system workflows.
• Improved collaboration between designers and developers.
• Less manual work when updating typography across multiple components.

Supporting percentage-based line height variables would make Figma's variable system more powerful and align it better with common typography workflows.

Would love to see this feature in Figma!
