Best bet is to locate the fridge of interest in a physical store near to you and personally measure it for yourself..
"PDFs" of the owners manuals are often pretty generic for home fridges and generally do not list all dimensions (only the max dimension if it is listed at all) and online places like Amazon list the shipping box dimensions..
Magic Chef, GE, Haier and a few other brands in the 10 CuFt apartment size home fridges are made by the same manufacturer in China. You will notice when you open them and look inside the freezer and fridge on the back wall will have the same basic look. Some may even share the same interior shelving and if your current fridge is one of those you might be able to find a newer model with similar door parts and use the new fridge model to order parts.
