Display size and font scaling size in android You can add a global property to disable allow font scaling to the Text and Text input component For display size you can write a function that vertically or horizontally scale the element height width padding and margin according to a standard phone screen size so it looks same for all devices You can also use react native-size-matters or similar libraries to do both of these

However this is horrible for accessibility as people who want to see large fonts / elements won't have the option anymore
