This works out great! Pretty easy to put together. I bought this for my daughters room. Replacing the one that held her baby shoes. Now she has big shoes like mom and day. (Pre-teen). 
I did not measure the closet door. I just assumed my door was standard size. The rack is so large that we have to put it on the outside of her door, facing into the room. That defeats the purpose. But that’s my fault for not measuring. 
I still recommend. Make sure you measure.
