+# useBreakpoints
+
+Reactive viewport breakpoints.
+
+## Usage
+
+```ts
+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>
+```
+
+#### 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
+
+```ts
+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`](../useSSRWidth/index.md)
+
+## 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:_
+
+```js
+import { breakpointsTailwind } from '@vueuse/core'
+// and so on
+```
+
+## Type Declarations
+
+```ts
+export * from "./breakpoints"
+export type Breakpoints<K extends string = string> = Record<
+  K,
+  MaybeRefOrGetter<number | string>
+>
+export interface UseBreakpointsOptions extends ConfigurableWindow {
+  /**
+   * The query strategy to use for the generated shortcut methods like `.lg`
+   *
+   * 'min-width' - .lg will be true when the viewport is greater than or equal to the lg breakpoint (mobile-first)
+   * 'max-width' - .lg will be true when the viewport is smaller than the xl breakpoint (desktop-first)
+   *
+   * @default "min-width"
+   */
