Writers talk about manuscript length in word count because it is a common unit across all formats. I never really had an answer for how long my book is when a non writer asked.
Then I go on about how it changes according to format. MS word? paperback? hardcover? What is the typesetting or font? all of that ends up with a different page count.
My current WIP, WEREWOOF, an adult contemporary paranormal romance, is currently 40K words long in its first draft. If i change my View settings to letter size (Times New Roman, 12 point font double spaced), it comes out to 173 pages.
My main project that is almost done with edits. SOULCHASER is 88K words and 321 pages (formatted the same way). SOULCHASER is second world fantasy with romantic elements. but because of the worldbuilding, it has a lot of description mixed in with the dialogue.
Why does dialogue matter? Basic grammar rules create more line breaks in dialogue heavy stories. WEREWOOF is (as of 1/5/2021) about as long as Lion The Witch and the Wardrobe by C.S. Lewis (36,363 words). Soulchaser is about the same length as Persuasion by Jane Austen (87,978 words).
