Full Width of Image and Maintain Aspect Ratio React Native

As a React Native developer, I have often faced the problem of full width images while maintaining their aspect ratio. When we try to set the width of an image to 100%, it stretches the image horizontally and distorts the aspect ratio. But, we can solve this problem with the help of some simple CSS.

Method 1: Using resizeMode property

The easiest way to maintain the aspect ratio of an image is to use the resizeMode property. We can use the resizeMode property to set the value to 'contain'. The 'contain' value will make sure that the entire image is visible and maintains its aspect ratio.

<View style={{flex:1, alignItems:'center', justifyContent:'center'}}>
  <Image source={{uri: 'https://example.com/image.png'}} style={{width:'100%', resizeMode:'contain'}} />
</View>

In the above code, we have used the resizeMode property and set its value to 'contain'. This will make sure that the entire image is visible and maintains its aspect ratio even if the width of the image is set to 100%.

Method 2: Using aspectRatio property

We can also use the aspectRatio property to maintain the aspect ratio of an image. The aspectRatio property takes a numerical value that represents the aspect ratio of the image. For example, if the width of an image is 100 and its height is 200, then its aspect ratio will be 0.5 (200/100).

<View style={{flex:1, alignItems:'center', justifyContent:'center'}}>
  <Image source={{uri: 'https://example.com/image.png'}} style={{width:'100%', aspectRatio: 0.5}} />
</View>

In the above code, we have used the aspectRatio property and set its value to 0.5. This will maintain the aspect ratio of the image even if the width of the image is set to 100%.

Conclusion

There are multiple ways to maintain the aspect ratio of an image while setting its width to 100% in React Native. We can use either the resizeMode property or the aspectRatio property to achieve this. Both methods are equally effective and can be used based on the specific requirements of our project.
