Changing the Font Size
There’s a clever feature that automatically scales up the text to be as large as possible within the note. It’s a bit like writing on physical sticky notes - a short note can be in big, bold letters, while a longer note needs smaller writing to fit.
Without this handy feature, the board might look a bit cluttered and harder to read.
Here's How to Scale Up Sticky Text Font
Navigate to Settings (which you'll find in your profile)
Check the box labeled "Scale up sticky text font." Your text size will now automatically fill the the sticky note, make it as big and readable as possible.
