Continue to allow about 24 inches of space from the rod to the back of the wall but increase the height of the top rod.
For a single rod closet the standard rod height is 66 5 inches.
This is the location for the bottom hanging rod.
Continue measuring up the wall to a height 84 inches.
Measure up from the floor to a height of 42 inches and mark the wall lightly with a pencil.
The standard height dual closet rods.
If you are installing dual rods in the closet the hanging measurements and spacing changes.
In these cases the upper rod is usually installed at a height of 80 inches while the lower rod is positioned at 40 inches.
Another factor that will shift this height is if you choose to use a double rod system in your closet.
