If there's a shop that sells ukuleles anywhere near you, try to go there and play different sizes. I didn't realize that a soprano would be uncomfortably small for me until I tried playing one at a music shop that carried a bunch of ukuleles in different sizes. I ended up playing concert and tenor ukuleles there and feeling a lot more comfortable with them. (I now own a concert and two tenors). If there isn't a shop nearby, check to see if there are other ukulele players in your area whose ukuleles you might be able to test drive. BTW, I'm also considering buying a baritone (more for the different sound than for the size of the neck). If you end up preferring a baritone for the neck size but you've already begun to learn chords in GCEA tuning, you can set up a baritone ukulele with GCEA tuning by stringing it with a set of tenor-sized GCEA strings.
