+# useSSRWidth
+
+Used to set a global viewport width which will be used when rendering SSR components that rely on the viewport width like [`useMediaQuery`](../useMediaQuery/index.md) or [`useBreakpoints`](../useBreakpoints/index.md)
+
+## Usage
+
+```ts
+import { provideSSRWidth } from '@vueuse/core'
+
+const app = createApp(App)
+
+provideSSRWidth(500, app)
+```
+
+Or in the root component
+
+```vue
+<script setup lang="ts">
+import { provideSSRWidth } from '@vueuse/core'
+
+provideSSRWidth(500)
+</script>
+```
+
+To retrieve the provided value if you need it in a subcomponent
+
+```vue
+<script setup lang="ts">
+import { useSSRWidth } from '@vueuse/core'
+
+const width = useSSRWidth()
+</script>
+```
+
+## Type Declarations
+
+```ts
+export declare function useSSRWidth(): number | undefined
+export declare function provideSSRWidth(
+  width: number | null,
+  app?: App<unknown>,
+): void
+```
