useBreakpoints

Reactive viewport breakpoints.

Usage

import { breakpointsTailwind, useBreakpoints } from '@vueuse/core'

const breakpoints = useBreakpoints(breakpointsTailwind)

const smAndLarger = breakpoints.greaterOrEqual('sm') // sm and larger
const largerThanSm = breakpoints.greater('sm') // only larger than sm
const lgAndSmaller = breakpoints.smallerOrEqual('lg') // lg and smaller
const smallerThanLg = breakpoints.smaller('lg') // only smaller than lg

vue

<script setup lang="ts">
import { useBreakpoints } from '@vueuse/core'

const breakpoints = useBreakpoints({
  mobile: 0, // optional
  tablet: 640,
  laptop: 1024,
  desktop: 1280,
})

// Can be 'mobile' or 'tablet' or 'laptop' or 'desktop'
const activeBreakpoint = breakpoints.active()

// true or false
const laptop = breakpoints.between('laptop', 'desktop')
</script>

<template>
  <div :class="activeBreakpoint">
    ...
  </div>
</template>

Shortcut Methods

You can access breakpoints directly as properties on the returned object. These return reactive refs.

const breakpoints = useBreakpoints({
  tablet: 640,
  laptop: 1024,
})

// Equivalent to breakpoints.greaterOrEqual('tablet') with min-width strategy
const isTablet = breakpoints.tablet

Strategy

The strategy option controls how the shortcut properties behave:

min-width (default, mobile-first): breakpoints.lg is true when viewport is >= lg
max-width (desktop-first): breakpoints.lg is true when viewport is < xl

const breakpoints = useBreakpoints(breakpointsTailwind, {
  strategy: 'max-width', // desktop-first
})

Available Methods

Method	Description
`greaterOrEqual(k)`	Reactive: viewport width >= breakpoint
`greater(k)`	Reactive: viewport width > breakpoint
`smallerOrEqual(k)`	Reactive: viewport width <= breakpoint
`smaller(k)`	Reactive: viewport width < breakpoint
`between(a, b)`	Reactive: viewport width between a and b
`isGreaterOrEqual(k)`	Non-reactive: returns boolean immediately
`isGreater(k)`	Non-reactive: returns boolean immediately
`isSmallerOrEqual(k)`	Non-reactive: returns boolean immediately
`isSmaller(k)`	Non-reactive: returns boolean immediately
`isInBetween(a, b)`	Non-reactive: returns boolean immediately
`current()`	Returns computed array of all matching breakpoints
`active()`	Returns computed string of the current active breakpoint

Server Side Rendering and Nuxt

If you are using useBreakpoints with SSR enabled, then you need to specify which screen size you would like to render on the server and before hydration to avoid an hydration mismatch

import { breakpointsTailwind, useBreakpoints } from '@vueuse/core'

const breakpoints = useBreakpoints(breakpointsTailwind, {
  ssrWidth: 768 // Will enable SSR mode and render like if the screen was 768px wide
})

Alternatively you can set this up globally for your app using provideSSRWidth

Presets

Tailwind: breakpointsTailwind
Bootstrap v5: breakpointsBootstrapV5
Vuetify v2: breakpointsVuetifyV2 (deprecated: breakpointsVuetify)
Vuetify v3: breakpointsVuetifyV3
Ant Design: breakpointsAntDesign
Quasar v2: breakpointsQuasar
Sematic: breakpointsSematic
Master CSS: breakpointsMasterCss
Prime Flex: breakpointsPrimeFlex
ElementUI / ElementPlus: breakpointsElement

Breakpoint presets are deliberately not auto-imported, as they do not start with use to have the scope of VueUse. They have to be explicitly imported:

import { breakpointsTailwind } from '@vueuse/core'
// and so on
