SASS variables

Vuetify uses SASS/SCSS to craft the style and appearance of all aspects of the framework.


Vuetify works out of the box without any additional compilers needing to be installed. Changing or using SASS variables though obviously requires the SASS compiler.


Vite provides built-in support for sass, less and stylus files. There is no need to install Vite-specific plugins for them, but the corresponding pre-processor itself must be installed. Vuetify needs sass as a preprocessor so install it:

npm install -D sass

for more information:


You can select pre-processors (Sass/Less/Stylus) when creating the project. If you did not do so, the internal webpack config is still pre-configured to handle all of them. You just need to manually install the corresponding webpack loaders:

npm install -D sass-loader sass

for more information:

Basic usage

Some variables are not used by vuetify components and are safe to modify without any additional configuration.

- import 'vuetify/styles'
+ import './main.scss'
@use 'vuetify' with (
  $utilities: false,
  $color-pack: false,

Component specific variables

Customising variables used in components is a bit more complex and requires the use of a build plugin. Follow the plugin setup guide from treeshaking then add styles.configFile to the plugin options:

// Vite/Nuxt
  styles: { configFile: 'src/settings.scss' }

// Webpack/Vue CLI
new VuetifyPlugin({
  styles: { configFile: 'src/settings.scss' }

And create a settings file. This can be named anything you like, just make sure to reference it in the plugin options.

@use 'vuetify/settings' with (
  $utilities: false,
  $button-height: 40px,

configFile will be resolved relative to the project root, and loaded before each of vuetify’s stylesheets. If you were using the basic technique from above, make sure to remove it and switch back to import 'vuetify/styles'. You can keep main.scss for other style overrides but don’t do both or you’ll end up with duplicated styles.

Usage in templates

You can access global and per-component variables in Vue templates simply by importing the settings file:

<style lang="scss">
  @use './settings';

  .my-button {
    height: settings.$button-height;

Keep in mind that to obtain settings from Vuetify, you must forward its variables from within your local stylesheet. In the following example we modify settings.scss to forward instead of use:

- @use 'vuetify/settings' with (
+ @forward 'vuetify/settings' with (


When using sass variables, there are a few considerations to be aware of.

Duplicated CSS

Placing actual styles or importing a regular stylesheet into the settings file will cause them to be duplicated everywhere the file is imported. Only put variables, mixins, and functions in the settings file, styles should be placed in the main stylesheet or loaded another way.

Build performance

Vuetify loads precompiled CSS by default, enabling variable customisation will switch to the base SASS files instead which must be recompiled with your project. This can be a performance hit if you’re using more than a few vuetify components, and also forces you to use the same SASS compiler version as us.

sass-loader with api: 'modern'

You might have to write a custom importer plugin to load the settings file.
