We designed our rack curtains based on the dimensions of the rack frame. A 2-High refers to two racks stacked on top of each other with an open space at the foot of each rack. A 3-High is divided into three and does not have an open space at the foot of the rack. A 4-High measures the same as a 3-High.
The racks found in E-6 and below berthing spaces are often narrower because of the storage locker coffin beneath the mattress. Each of the racks in the E-6 and below berthing spaces are more than likely the 3-High or 4-High. The racks found in Officer/Chief staterooms don't have the storage locker.
In most cases, Marines and Sailors will be in the berthing space designated for their rank. E-6 and below will be in the enlisted berthing. Officers and Chiefs are in staterooms. Stateroom racks can vary from 2-High to 3-High without a storage coffin located beneath the mattress. Officers that are an O4 and above will usually share a room with one other or have a room to themselves and will not require any rack curtains.
