+# useDevicePixelRatio
+
+Reactively track [`window.devicePixelRatio`](https://developer.mozilla.org/docs/Web/API/Window/devicePixelRatio)
+
+> NOTE: there is no event listener for `window.devicePixelRatio` change. So this function uses [`Testing media queries programmatically (window.matchMedia)`](https://developer.mozilla.org/en-US/docs/Web/CSS/Media_Queries/Testing_media_queries) applying the same mechanism as described in [this example](https://developer.mozilla.org/en-US/docs/Web/API/Window/devicePixelRatio#monitoring_screen_resolution_or_zoom_level_changes).
+
+## Usage
+
+```ts
+import { useDevicePixelRatio } from '@vueuse/core'
+
+const { pixelRatio } = useDevicePixelRatio()
+```
+
+## Component Usage
+
+```vue
+<template>
+  <UseDevicePixelRatio v-slot="{ pixelRatio }">
+    Pixel Ratio: {{ pixelRatio }}
+  </UseDevicePixelRatio>
+</template>
+```
+
+## Type Declarations
+
+```ts
+/**
+ * Reactively track `window.devicePixelRatio`.
+ *
+ * @see https://vueuse.org/useDevicePixelRatio
+ *
+ * @__NO_SIDE_EFFECTS__
+ */
+export declare function useDevicePixelRatio(options?: ConfigurableWindow): {
+  pixelRatio: Readonly<Ref<number, number>>
+  stop: WatchStopHandle
+}
+export type UseDevicePixelRatioReturn = ReturnType<typeof useDevicePixelRatio>
+```
