Is my book too long?

Recently, I've noticed that many authors on social media claim their books are 50k-60k in length, while an 80k-word book is

considered quite long. I've been writing for years now (unpublished), but I've always thought that a good book should have at least 90k-100k words, especially when world-building is a part of it.

My first book "Death of a Victorian Gentleman" is the first part of a series, and it will probably be the shortest book of the series, but it has over 130k words in total. Is this too long? Honestly, I could never create an authentic historic setting, flesh out my characters, and send them on their journey of discovery and development with fewer words.

With the following books in my series, I'm aiming for about 150k-160k words per book. Sometimes I still wonder whether my novel might benefit from being shorter...
