I suppose you could make them snack size, but the ones I make are intended to be an entire hearty meal. That is true for the ones I have had in Michigan's UP and the one I bought in St. Ives in Cornwall. Mine are about 6" wide and 4" tall, and maybe 2-3 inches thick. Here is an article from Sault Ste Marie, Michigan, that has a lot of photos of pasties, and you can see how big they are! There are also photos here of the inside of pasties, except many people do not believe carrots should be included in pasties!

They would fall apart if you took them out of the wrapper. I was driving a rental car, so I ate mine out of the paper wrapping. I got mine in St. Ives, which looks 100% like the fictional Portwenn from the Doc Martin series, and in fact the real town it is filmed in (Port Isaac) is just a few miles from St Ives down the coast.
In the U.S., they are put on a plate and you use a knife and fork to eat them. The ones in this article look a lot like mine, but this lady left out the rutabaga/swede because she does not like it. Terrible. Good photos, and you can see the size from the size of her hands as she is crimping them.
