do dahlias grow taller each year?

I am wondering if the size of the tuber affects the height of the plant that grows? Dahlias do not over winter here, and I think my garage is too cold and basement too warm to properly over winter tubers. Costco however does have very good deals if I want to treat dahlias like annuals here. I want to plant them along the back of my flower bed though - so taller is definitely better.
