React native check if tablet or screen in inches

I've established a different render logic for tablets and mobile devices. I was wondering if there is a way to get the screen size in inches or maybe even any module to automatically detect if the device is a tablet or not.

The reason I am not using the dimensions api directly to get the screen resolution is that there are many android tablets with lower resolution than many of their mobile counterparts.

Thanks.

Using the below example you can find the device is ios, android, tablet or small device

import { Platform, Dimensions } from 'react-native';

const { width, height } = Dimensions.get('window');
const aspectRatio = height / width;

const isIOS = Platform.OS === 'ios';
const isAndroid = Platform.OS === 'android';

const isTablet = aspectRatio < 1.6; // Assumes 4:3 aspect ratio for tablets
const isSmallDevice = width < 375; // Assumes iPhone 6/7/8 width as small device

// Example usage in a component
const MyComponent = () => {
  const deviceType = isTablet ? 'tablet' : 'phone';
  const platformType = isIOS ? 'iOS' : 'Android';

  return (
    <View>
      <Text>Device Type: {deviceType}</Text>
      <Text>Platform Type: {platformType}</Text>
    </View>
  );
};

use

npm install --save react-native-device-info

then

import Device from 'react-native-device-info';

const isTablet = Device.isTablet();

If you don't want to use library react-native-device-info use can use this code below, not sure it't work perfect but may be help

export const isTablet = () => {
  let pixelDensity = PixelRatio.get();
  const adjustedWidth = screenWidth * pixelDensity;
  const adjustedHeight = screenHeight * pixelDensity;
  if (pixelDensity < 2 && (adjustedWidth >= 1000 || adjustedHeight >= 1000)) {
    return true;
  } else
    return (
      pixelDensity === 2 && (adjustedWidth >= 1920 || adjustedHeight >= 1920)
    );
};

react-native-device-detection

if(Device.isTablet) {
  Object.assign(styles, {
    ...
  });
}

Based on PixelRatio and Screen's height,width.

Based on @martinarroyo's answer, a way to go about it use the react-native-device-info package.

However the android implementation is based on screen resolution. That can be a problem as there are many tablet devices with a lower resolution than many mobile devices and this can cause problems.

The solution I will be using and am suggesting is use react-native-device-info for apple devices and for android devices go with a simple ratio logic of the type:

function isTabletBasedOnRatio(ratio){

if(ratio > 1.6){
    return false;
}else{
    return true;
}

}

This is not a perfect solution but there are many small tablets with phonelike ratios as well or even phablets ( android is blurry) and this solutions is inclusive towards those as well.

You can use the react-native-device-info package along with the Dimensions API. Check the isTablet() method and apply different styles according on the result.
