React Native Show SuperScript and SubScript

React Native SuperScript SubScript

React Native SuperScript SubScript is a React Native Version of tags available in HTML known as <sup> superscript and <sub> subscript.

Superscript tag sets the half of the character above on the text writing line like (10am) and the same as but in a different manner the Subscript tag is opposite of superscript, In subscript tag, the next character would be halfway down to the previous one like (10am).

lineHeight is a style attribute that will help us to make Superscript and Subscript text.

LineHeight Text Type
30 Shows normal Text
18 Shows superscript
37 Shows subscript

Here is a simple example to show how to show SuperScript and SubScript.

Show SuperScript Using

<Text style={{fontSize: 15, lineHeight: 18}}>am</Text>

Show SubScript Using

<Text style={{fontSize: 15, lineHeight: 37}}>am</Text>

In this example,  we will show a simple sentence that will have a SuperScript and SubScript text. So let’s get started.

To Make a React Native App

Getting started with React Native will help you to know more about the way you can make a React Native project. We are going to use react native command line interface to make our React Native App.

If you have previously installed a global react-native-cli package, please remove it as it may cause unexpected issues:

npm uninstall -g react-native-cli @react-native-community/cli

Run the following commands to create a new React Native project

npx react-native init ProjectName

If you want to start a new project with a specific React Native version, you can use the --version argument:

npx react-native init ProjectName --version X.XX.X

Note If the above command is failing, you may have old version of react-native or react-native-cli installed globally on your pc. Try uninstalling the cli and run the cli using npx.

This will make a project structure with an index file named App.js in your project directory.


Open App.js in any code editor and replace the code with the following code


//React Native Show SuperScript and SubScript

//import React in our code
import React from 'react';

//import all the components we are going to use
import {SafeAreaView, StyleSheet, View, Text} from 'react-native';

const App = () => {
  return (
    <SafeAreaView style={{flex: 1}}>
      <View style={styles.container}>
        {/*View to wrap multiple text*/}
            flexDirection: 'row',
            alignItems: 'flex-start'
          {/*View to wrap multiple text*/}
          <Text style={{fontSize: 20, lineHeight: 30}}>
            Time is 10
          <Text style={{fontSize: 15, lineHeight: 18}}>
          <Text style={{fontSize: 20, lineHeight: 30}}>
            {' '}
            and I am late or the class
            flexDirection: 'row',
            alignItems: 'flex-start',
            marginTop: 30,
          {/*View to wrap multiple text*/}
          <Text style={{fontSize: 20, lineHeight: 30}}>
            Time is 10
          <Text style={{fontSize: 15, lineHeight: 37}}>
          <Text style={{fontSize: 20, lineHeight: 30}}>
            {' '}
            and I am late or the class

const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
    margin: 10,

export default App;

To Run the React Native App

Open the terminal again and jump into your project using.

cd ProjectName

1. Start Metro Bundler

First, you will need to start Metro, the JavaScript bundler that ships with React Native. To start Metro bundler run following command:

npx react-native start

Once you start Metro Bundler it will run forever on your terminal until you close it. Let Metro Bundler run in its own terminal. Open a new terminal and run the application.

2. Start React Native Application

To run the project on an Android Virtual Device or on real debugging device:

npx react-native run-android

or on the iOS Simulator by running (macOS only)

npx react-native run-ios
