The suggested answer using Dimensions is now discouraged. See: https://reactnative.dev/docs/dimensions

The recommended approach is using the useWindowDimensions hook in React; https://reactnative.dev/docs/usewindowdimensions which uses a hook based API and will also update your value when the screen value changes (on screen rotation for example):

import {useWindowDimensions} from 'react-native';

const windowWidth = useWindowDimensions().width;
const windowHeight = useWindowDimensions().height;

Note: useWindowDimensions is only available from React Native 0.61.0: https://reactnative.dev/blog/2019/09/18/version-0.61
