I have this punch but haven't used it for a while. It is a fun punch to have. The only problem I had is that I mail most of my cards, and the bow really stuck up, so I needed extra postage. And the bow got kind of mashed in the mail.
Dimensions of the finished bow are pretty small, Finished bow size: 2-1/4" x 7/8".
Here is a link to a Pinterest page showing the bows on cards, so you can get a better idea of the size of the bow:
