I prefer to have a nice sized towel and I wouldn't cut it down for any reason. There are times when having a nice big towel especially when it is colder outside the shower is a nice thing. Also useful for privacy and such. If you really must have a tiny towel you can probably pick one up cheap at some of the places people mentioned above but the only thing I like having my tiny towel for is cleaning dishes or drying hair (but typically that is when I am traveling/car camping and less when touring)
