The letter-spacing attribute controls spacing between text characters, in addition to any spacing from the kerning attribute.

If the attribute value is a unitless number (like 128), the browser processes it as a <length> in the current user coordinate system.

If the attribute value has a unit identifier, such as .25em or 1%, then the browser converts the <length> into its corresponding value in the current user coordinate system.

Note: As a presentation attribute, letter-spacing can be used as a CSS property. See the css letter-spacing property for more information.

As a presentation attribute, it can be applied to any element but it has effect only on the following eight elements: <altGlyph>, <text>, <textPath>, <tref>, and <tspan>

<svg viewBox="0 0 400 30" xmlns="http://www.w3.org/2000/svg">
  <text y="20" letter-spacing="2">Bigger letter-spacing</text>
  <text x="200" y="20" letter-spacing="-0.5">Smaller letter-spacing</text>

Usage notes
