The height of a truck cap all depends on the type of truck you have.
Every fiberglass cap is truck specific.
But the difference between the three different sizes of truck caps most always remains the same.
The size go from Cab-Hi, to Mid Rise, and then High Rise or Wedge.
The size difference is based off of the Cab-Hi cap.
Mid Rise is around 4 inches taller than Cab-Hi.
And High Rise is around 6 to 8 inches taller than Cab-Hi.
