Power Apps recognise different device layout. This layout represents Size property in your Canvas screen.
The list of size constants:
Screen Sizes
Name
Value
Device Type
ScreenSize.Small
1
Phone
ScreenSize.Medium
2
Tablet, held vertically
ScreenSize.Large
3
Tablet, held horizontally
ScreenSize.ExtraLarge
4
Desktop computer
There are no rows in this table
If you need to specify higher than Extra Large size, you can do it through the SizeBreakpoints property:
[576, 768,992,1200, 1400]
Demo
Select App and choose "Formulas" property, where your custom UDF function will be placed.
Then go to your particular screen and choose some Label controls.
Select your Label in your Power Apps scree, go to Font Size property, and put "DynamicFontSize" function with size of your screen as input value.
Output
I used my title "Tasker" label, where I put the function in FontSize property.

Try clicking the ··· in the right corner or using a keyboard shortcut (
