Design Handoff tips
Figma outputs measurements in pixels. When implementing in CSS, convert font sizes and spacing to rem units to respect user browser preferences.
A quick mental shortcut: divide any px value by 16 to get rem (at the 16px default base). 24px Γ· 16 = 1.5rem. This tool handles any base font size.
For design tokens: 1rem = 16px base is standard. Capture all your token values in rem so they scale correctly when users adjust their font preferences.
Click any entry in the common sizes table to load it into the converter. Quickly check 12px, 14px, 16px, 18px, 24px, and 32px against your current base size.
