They are VERY adjustable, so height is totally up to you. As far as width and depth that info can be found on the SPEC page for the BDI 8227-2 which I do not have in front of me at the moment. I can tell you that it will fit most ALL electronics items such as Stereo's, AMP's, VCR/DVD Players, etc... with no problem. Even fits my Panamax M5400-PM perfectly.
