Steps to reproduce

1. Initialize a new Expo project & start it.

npx create-expo-app RNUseWindowsDimensions
cd RNUseWindowsDimensions
npm run ios

2. Replace code in ./App.js with example code for documentation of useWindowDimensions here.

import React from 'react';
import {View, StyleSheet, Text, useWindowDimensions} from 'react-native';

const App = () => {
  const {height, width, scale, fontScale} = useWindowDimensions();
  return (
    <View style={styles.container}>
      <Text style={styles.header}>Window Dimension Data</Text>
      <Text>Height: {height}</Text>
      <Text>Width: {width}</Text>
      <Text>Font scale: {fontScale}</Text>
      <Text>Pixel ratio: {scale}</Text>
    </View>
  );
};
const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
  },
  header: {
    fontSize: 20,
    marginBottom: 12,
  },
});

export default App;

3. Observe that the values returned from the hook don't update when the orientation of the device/simulator change.

In this demo we see that the height value is always greater than the width value, even when the simulator is in landscape orientation.

I think it may be related to issue #29290. In that issue the op states values are swapped. In this case values are simply wrong. Thus I thought it was worth opening up a new issue.

In your app.json, try changing "orientation": "portrait" to "orientation": "default".
Another thing to try is to reload the application (by pressing r in the console where you ran npm start),
and/or Ctrl + C followed by npm start (or npm run ios) to restart the server,
and then maybe m to toggle away the dev menu.
