What does this tool do?
The Letter Spacing Generator is a visual CSS tool that lets you tune letter-spacing, word-spacing, line-height and font-size with sliders. Web designers and developers can experiment in a live preview and copy ready-to-use CSS with a single click.
How to use it
- Adjust the values and options.
- See the result in the live preview.
- Copy the generated CSS/code into your project.
Four typography controls
Separate sliders cover letter-spacing (-5px to 30px), word-spacing (-10px to 40px), line-height (0.8 to 3) and font-size (10px to 60px). Every change is reflected instantly in the preview text, so you see exactly how the result renders in a browser. Below the preview, a ready-to-use CSS block containing all four properties is generated, which you can copy straight into your project with the copy button.
Letter spacing vs word spacing
letter-spacing adjusts the gap between individual characters and gives headings an airy, modern feel. word-spacing only widens or tightens the gap between whole words. Negative values let you condense type, while positive values create a breathable layout. Replace the sample sentence with your own copy to test the settings on real content before committing the values to your stylesheet.
Frequently asked questions
How do I use the generated code?
Paste the four copied lines (letter-spacing, word-spacing, line-height, font-size) inside any CSS selector you want, for example an h1 rule or a .heading class.
Why would I use negative letter spacing?
Large headings can look too loose; a small negative letter-spacing value, such as -1px, pulls characters tighter for a more balanced display.
Can I use em instead of px?
The tool outputs values in px, but after copying you can manually swap px for em or rem to get scalable typography that responds to the parent font size.
