For a while, my blogger font was small when I was using a "normal" size font when I typed a post. If I tried to resize it to "large" it was too large. After some playing around and googling for some answers, I figured it out. It was very simple fix. I put together this slide show to show you how easy it is to correct this problem
After thinking about it for a while, I may have unknowingly made some changes to the font when I "redecorated" my blog. Oops!!! Don't know for sure though.
Hope this may help you out and save some time if you run into this problem.
