the same height but a 16" tire is usually narrower. What you want for deep snow is a contact patch which is long an narrow. Also, if your driving on a packed down snow surface a narrower tire will not tramline as bad as a wider tire (ie if your driving in ruts a wide tire sucks).

patch was different for the the different size tires. Its my understanding that the size of the contact patch doesn't change. What changes is the dimension of the contact patch. A narrower tire (narower & longer conact patch) is better for snow.

I have Pirrelli Snowsport 210's mounted on Audi steel wheels that I used last winter...they were great but I hated the look for 5 months. I've just put Ronal R38's on my Conti 17's and I'm mounting 17" snows on my stock sport rims. With quattro I'll be just fine.
