I believe you should minimally give dimensions as depth, and lower bout width, as this question made me check my owns : I have a 12-fret tricone Hot Rod which fits perfectly in its case. It is some 3 inches (8 cm) deep.
My classicals (Ramirez R-4 and Aria AC-80) would get in but are some 1-2 cm too thick to allow dobro case to close.
The lower bout of my Martin 000-18 is just a bit too large to fit in. Taylor 512 (1995) would almost fit in.
