I am in the planning stages of 2 bookcases on both sides of the fireplace. They are going to be 61 inches wide. The bottoms are going to be cabinets and then above that is shelves. My question….support wise would you put a support in the middle basically making each bookshelf two bookshelves? I feel like I almost have to with it being so wide bit I’m not sure

#1 posted 09-26-2017 01:57 AM is a website which allows you to check shelves. It is not useful for shelves that are attached to the back.

I usually limit bookshelves to about 36”, so yes, I would put a divider in the center.

To avoid the center divider, you can make the shelves extra thick and/or add a “nosing” to the front edge to add stiffness. The Sagulator (link in post # 1 above) can help you calculate the “sag factor” of various options.

If you are putting books on the shelves, then I would certainly add a center support in addition to a nose on the front. Even 30” shelves full of books will sag.

Excellent. thanks so much for the responses. I kind of figured what I needed to do but when budgets are involved, I wanted to double check
