Although you certainly have room for four, I think that odd numbers look best. I would hang three of them but I think you might want bigger ones than the size you've found.

I've been looking a lanterns for a small vestibule and everything I look at is way too big, so you shouldn't have a hard time finding larger ones. Circa Lighing has a lot of lanterns that seem like the style you are after.

Looks like you will have a stunning hallway! Love the arch and long lantern view.

Thanks so much Kendra. Circa looks nice but doesn’t appear to sell in Canada unfortunately

Bummer. You can try finding a particular light you might like on there and google it to see who sells it in Canada. The lights on Circa are also sold through other companies.
