How to Change TextInput Font in React Native

A great user interface is essential for engaging app experiences, and fonts play a big role in that. In React Native, the TextInput component allows easy text input but defaults to the system font. This blog post will teach you how to change the font in TextInput with examples and explanations.

Prerequisites

• A working React Native development environment
• Basic understanding of React Native and JavaScript

Set up a Basic TextInput

Firstly, let’s start by creating a simple TextInput.

import React from 'react';
import { View, TextInput } from 'react-native';

const App = () => {
  return (
    <View>
      <TextInput placeholder="Default Font" />
    </View>
  );
};

export default App;

Change Font Using Inline Style

You can directly specify a font family for your TextInput using inline style.

<TextInput
  placeholder="Custom Font"
  style={{ fontFamily: 'monospace' }}
/>

The style prop allows you to define custom styles. The fontFamily sets the desired font.

Use StyleSheet for Scalability

Using inline styles might not be practical for larger apps. StyleSheet can make your code cleaner and more manageable.

import { StyleSheet } from 'react-native';

const styles = StyleSheet.create({
  customFontInput: {
    fontFamily: 'Courier New',
  },
});

// In the component
<TextInput
  placeholder="Custom Font"
  style={styles.customFontInput}
/>

The StyleSheet.create function organizes your styles. The customFontInput style includes the fontFamily property.

Conclusion

Changing the font in React Native’s TextInput is a straightforward process but adds a polished look and feel to your app. Whether you use built-in fonts or custom ones, setting them up is relatively simple and goes a long way in enhancing the user interface.
