REALLY wish Wayfair would've been clearer about the heights of these shelves. While it's true that, from board to board, these shelves measure 13 inches. HOWEVER - there's a metal support bar under each board that compromises the height of each shelf by an inch. I bought these shelves to store records thinking that 13 inches would be perfect because it'd give me a whole inch of clearance for storage. That was NOT the case. I BARELY have enough room to store them because of that bar. I'll have to store them at an angle to not damage them. The shelves are great besides that. If you're buying these for books or nick-nacks, you'll be just fine.
