Changing Font Size Of Labels Depending On Text Length

I have a report that prints labels (similar to avery labels) which pulls data from a query. These labels are all unique and vary in length. Due to the length variance, I want the font size to get smaller for labels with more characters. I want the text to go down to another line when necessary.

In my report under the OnPage Event Procedure I wrote this:

Private Sub Report_Page()
If Len(Text2) > 20 Then Text2.FontSize = 8
If Len(Text2) > 10 And Len(Text2) < 21 Then Text2.FontSize = 10
If Len(Text2) < 11 Then Text2.FontSize = 14
End Sub

This works to some degree but the problem is that once there is a longer label, all of the proceeding labels are resized & the longer label that should have been resized was not.

Is there another place I should be writing this code? I looked under events for the textbox but there doesn't seem to be anything that would work since none of them would trigger when printing labels
