When I bred and showed Rabbits the rule of thumb for hutches was a square foot of space for every pound of weight of Rabbit, so most of the commercially made ones are not even big enough for a 4 pound Dwarf. Most are far too narrow even if they look tall and long enough from the front. The Rabbit shoudl be able to lie fully across the narrowest side.

I used to Have English Rabbits which are 6 to 8 pounds as adults. I had tiered hutches which were 3 feet x 2 feet deep x 18 inches high for the single rabbits, and 4 feet x 3 feet for the females who would sometimes have babies.
