sizes in units

[kedXD]

Is there any reason behind going for sizes in decimals?
Ex. fonts are like sm 12.25, lg 15.75 and padding 8.75 and 5.25 etc. Shouldn't it be expressed in numbers like 12, 6, 8 etc?

Hello, this is because we want the font sizes we use in libraries to match the font sizes in the UI Kit. Since we use REM, this situation applies to font sizes, spacing, and sizing values. In summary: Because the base font size we use in UI Libraries is 14px, it's likely that the resulting sizes will have decimal values.

Forgive my ignorance, but what is the most effective way to update our kit to work in multiples of 2/4/8 etc?
I've read that updating the root-level font size to 16px is a way to do this, but the Figma UI kit 3.0.1 already has Base font size as 16px in token studio settings?

In Tokens Studio Settings, you must link the base font size to the app.font.size token. It is actually 14px. So, currently use 14px as the base font size in the updated Figma UI Kit. You need to set it in the Tokens Studio settings.

After this, you can switch to any desired base font size by changing the app.font.size token.

Perfect, changed {app.font.size} to 16 after updating token studio settings. Exactly what I needed. Big thanks @onursenture .
