# Objective - The default font size is too small to be useful in examples or for debug text. - Fixes #13587 ## Solution - Updated the default font size value in `TextStyle` from 12px to 24px. - Resorted to Text defaults in examples to use the default font size in most of them. ## Testing - WIP --- ## Migration Guide - The default font size has been increased to 24px from 12px. Make sure you set the font to the appropriate values in places you were using `Default` text style.
