Ok, read the measurements!
I saw this and purchased, thinking that it would be the same size as the bookholder part of the music stand.
Nope! Waaaay bigger.
I can fit my musicstand, my guitar stand, footstool, the round base for my mic stand and two gooseneck stands. There's still more room and in the front, there's a pocket for a musicbook.
Excellent bag, has saved me two extra trips to and from the car!
