I have a three-year old wisteria and want to provide proper support for it as it grows. I understand that it needs a sturdy support. What do you recommend? Trellis? If so want dimensions and how should vine be attached to it?

Although you can trim the tips of the vine if you are vigilant, a mature plant can easily be 30 feet long and as it ages the woody trunk is capable of twisting a flimsy support. The vine will twine and wind itself around almost anything. The key is that it be extremely sturdy because a mature vine can be as thick as a man's arm and will be woody and very heavy. Stout wooden pillars or a firmly footed brick support leading to a heavy duty top of perhaps 2 x 6 boards or heavy iron pipe might be strong enough.
