A cripple stud is a type of stud that is used above a door or above or beneath a window. They aren’t very different from other studs except that they are cut shorter so there is room for the opening. The making of a cripple stud greatly depends on the size of the object that will be put around it.
- Step 1: Measure the length of the window. Add four inches to this so you are compensating for the 2x4s that are placed around the window frame.
- Step 2: Determine how high up your window will rest and figure out how high the bottom cripple stud must be.
- Step 3: Add the length of the bottom cripple studs, the window and its frame and subtract it from the height of the wall. This will tell you how long the cripple stud will have to be above the window.
- Step 4: Cut out these 2x4s and nail them to your frame. Around the window frame there will be a set of two boards that circle the entire frame.
Using a Cripple Stud above a Door
Building a door is very much like building a window except that the cripple stud will be paced above the door and not below it.
