My guess is your windows font scaling setting is set to something like 125%. Try changing that to 100% and see if that makes a difference. We are aware of font scaling issues like this and have improved them some in SOLIDWORKS 2014 and 2015 and are making even more improvements in 2016.
I hope this helps,
Thank you! That was the setting... Control Panel/Appearances and Personalization/Display was at "Medium - 125%(default)"
Changing that to "Smaller - 100%" corrected the Measure Tool display issue.
