+# useMediaQuery
+
+Reactive [Media Query](https://developer.mozilla.org/en-US/docs/Web/CSS/Media_Queries/Testing_media_queries). Once you've created a MediaQueryList object, you can check the result of the query or receive notifications when the result changes.
+
+## Usage
+
+```ts
+import { useMediaQuery } from '@vueuse/core'
+
+const isLargeScreen = useMediaQuery('(min-width: 1024px)')
+const isPreferredDark = useMediaQuery('(prefers-color-scheme: dark)')
+```
+
+#### Server Side Rendering and Nuxt
+
+If you are using `useMediaQuery` 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 { useMediaQuery } from '@vueuse/core'
+
+const isLarge = useMediaQuery('(min-width: 1024px)', {
+  ssrWidth: 768 // Will enable SSR mode and render like if the screen was 768px wide
+})
+
+console.log(isLarge.value) // always false because ssrWidth of 768px is smaller than 1024px
+onMounted(() => {
+  console.log(isLarge.value) // false if screen is smaller than 1024px, true if larger than 1024px
+})
+```
+
+Alternatively you can set this up globally for your app using [`provideSSRWidth`](../useSSRWidth/index.md)
+
+## Type Declarations
+
+```ts
+/**
+ * Reactive Media Query.
+ *
+ * @see https://vueuse.org/useMediaQuery
+ * @param query
+ * @param options
+ */
+export declare function useMediaQuery(
+  query: MaybeRefOrGetter<string>,
+  options?: ConfigurableWindow & {
+    ssrWidth?: number
+  },
+): ComputedRef<boolean>
+```
