There is no one dimension, they vary by plane and location within the plane. Bins toward the front are smaller than bins in the back two thirds of the plane.

Typically at least in the middle of the planes four of these would fit next to each other.

737-800 and Max aircraft have a little larger bins and you might get six stacked on their thinnest side. 

737-700 especially at the front and rear are a little tighter.

Very tight at the front few rows.
