How it works

Design Inputs and Selections

The Letter Spacing Calculator applies the controls and values shown in its workspace. Use the displayed units and options; outputs reflect those selections and any assumptions stated on the page.

Output and Preview

The workspace shows the design value, preview, or code provided by this tool. Review units and format before applying the result elsewhere.

Review in the Target Context

Check generated values in the component, stylesheet, asset, or interface where they will be used. A tool preview does not replace review at the target widths and states.
