How hard is it to find over the door storage that fits?

I hope everyone has had a good holiday. Instead a dreaming of sugarplums and candy canes, I have been dreaming of organizing my closet. In the process. I have been searching all over New York City and online. It seems that the companies I have called that no one seems to know the width of the door hooks. I’m not going to name the long list of retailers (both online and brick and mortar) that I called who did not know the width of the door hooks. However, I have only found one retailer who actually lists the door thickness, Even though their products don’t fit my thick door, they are efficient enough to list the door hook thickness of their over the door storage products.
