I don't think there is a standard size for garages, and sizes have changed over the years. I've seen garages built in the 30s extendedsix feet to about four feet high to take a long nose 1960s sedan. Buicks, Caddys, 98 Olds got to almost 20 feet long before shrinking again.
Garages built for those 60s cars will take most pickup configurations, except maybe longbed crew, if the truck is not too high for the door.
Then when cars shrunk, they started buildind smaller garages, that won't take a shortbed crewcab or a longbed extended cab, and might be close on avregular cab.
Then cane SUV era and garages for Suburbans and Excursions. Iff you can fit an Excursion, you can fit most single rear wheel pickup.
I suggest you measure yourgarade, length, width, height. Then check sizes of differen truck configurations, cab size, bed length, capacity, 4x2 vs 4x4. for length and width,you don't need to check them all, except for Ram Megacab there isn't much difference length and width brand to brand. Height will vary a lot more. Used to be 4x4 sat higher, HD sat higher, but now there is a trend toward height for styling, and a 1/2 ton on 20" wheels might sit higher than a one-ton farm truck on 16 inch wheels.
My own garage has two sections, one will squeeze in a 2wd 3/4 ton Suburban, the other is 30 inches shorter and gets crowded by larger minivans.
