That is what I thought too. But then I read she measured and it was different so I googled...lol...this is what I found.
What does Finished size mean?
Finished size is the final dimensions of the product. If the item is a folder style then the finished size is the size when folded. If the item is flat, non-folding, then the dimensions listed are the complete size of that item.
But I do second on securing your stroller. I have heard some being stolen or misplaced. Ours wasn't but I purposely picked a color that would stand out rather then the generic color as it was a popular model. If yours is a popular model, I would put something that makes it pop. I have seen many dads reach out and grab a stroller only to have mom tell them that not the one and place it back place it back in the stroller parking area, but not the spot where it was left. So then you have lots of confused parents.
