I'm 4'11 and have a 26 inseam, I purchased an XS titus last year and it's worked great. I also made the switch to 24" tires a few years ago. I didn't want to make the switch initially (mainly I didn't want to look like a little kid), but the difference they made with standover is amazing. There are a lot more tire options now since many downhillers will run a 24" rear tire.
