Are British Romance Books Longer?

This is super random, but I’m currently reading Boyfriend Material and it’s 421 pages. That seems pretty long for a modern romance. At least longer than usual. It reminded me of a book I’ve read recently that had British characters and seemed longer than usual. I can’t for the life of me remember the book, I’m not sure I finished it because I wasn’t a fan. Maybe it just felt longer because I didn’t like it?

Is this a thing? Or is it just me reading two flukes relatively close together? Are British romance books longer than American ones?? These are the things that pop into my mind when I should be doing something else.
