Can't use variables to create a percentage on Letter Spacing

Thank you for providing feedback! I will share this with our internal team. Your input is highly valued, and we will take it into consideration for future enhancements.

What unit is currently used? I tried converting the percentage to REM but the text shifts when I assign the variable, so REM clearly isn’t the right unit.

It defaults to pixels on Letter-Spacing. I tried using a decimal but then it was just a decimal of a pixel.
This issue is also present on line height.

This is weird 😦 I cannot use line-height variables for our “label” text style because of this issue. I need to add 10% as a value, but % character is not permitted.

Actually, this problem exists since 2021… Any news about it? Thank you very much.

I just ran into this problem. What good is having a variable scoped to line-height if it ONLY supports a px value ??

Same issue. Cant setup negative 2% or value 😦

If pixel values are considered “number variables” then percentage values should be considered number variables too. Please get this fixed.

I’d just like to add to this as well. Would make it a lot easier to set up consistent styles.

Just wanted to chime in here and say that this is absolutely required for us as well. Not being able to use tokens for letter-spacing is a gap in our design system that we want to address as soon as possible.

​@y_toku are you able to confirm if this feature is being worked on?

Variables where we can set the unit (either percentage, em, rem, etc.) are soo much needed. I can’t add percentage-based letter-spacing or line-heights which is basically the norm in web design.

I’m trying to use percentage values like -2% for letter spacing in Figma, but it doesn’t seem to work. When I set it using variables, Figma defaults the value back to pixels. Just wondering does anyone know if there’s a workaround

Came back almost a year later to see if this has been fixed. Nope.

It’s 2035, still not fixed. 

Nearly 2026…perhaps too many devs devoted to AI now to hope Figma will ever get Letter Spacing to work with variable units like `%` & `rem`? 😭

Can’t believe this is still not fixed. 
I thought you push design systems… and we can’t create a basic design system with tailwind combability  (they have em tracking/letter-spacing)
At least allow the letterspacing field to accept string variables...
