Thought I'd share this Q&A I had with someone via email in case you have the same question! - Lori
Q: I am struggling to find data comparing the performances of the 2" square tags vs. the 2"x 3" tags. Are you aware of any studies comparing the two?
I've heard anecdotal evidence from a nearby college that the 2x3 tags are significantly better [they abandoned using the squares altogether] but I'm not finding much on the topic.
Many thanks for any information your can share.
