[Vuejs]-How to change the default typography in vuetify?

create a folder called scss and create a file called variables.scss in my case I use Montserrat

paste this

@import url('https://fonts.googleapis.com/css?family=Montserrat&display=swap');

$body-font-family: 'Montserrat';
$font-size-root: 14px !default;

finally in your global file (APP.vue) paste this

<style lang="scss">
@import "./scss/variables.scss";



v-app {
  font-family: $body-font-family !important;
}

</style>

as a recommendation use the !important
