The LU-11 will be okay, but the LU-21C is a better choice. There’s more to the story than just the size of your hands. Intonation can be a problem on short scale instruments like the the soprano uke. If you have a slightly misplaced fret or bridge saddle or simply high action, the ratio of the error to the scale length is greater with a short scale. When you buy a ukulele lanikai, the tone and intonation will be better on the larger concert size LU-21C.
