I have a set of 13,s on my travel guitar. Tension total is the same as 10,s on a 25 scale. My travel guitar is 21 1/4. I guess 14,s would be playable if the tension is similar to 12,s on a 25 guitar. http://www.mcdonaldstrings.com/stringxxiii.html
The calculator does not recognize 59. I calculated 56 as tuned up to F to get the same tension as 59
Edit: A set of 14's on 21 1/4 tuned to E standard is about 10 pounds less than 12's at E standard on 25.
