Headers explained. Headers are installed in all openings, whether it's a door, a window, or an opening between rooms. What holds your header up is your jack studs. Depending on your span and how much weight your header's holding, determines if you need more or less jack studs. You will always have at least one jack stud for any opening. A king stud goes fully from the bottom plate all the way up to your double top plate. Up here is your studs. These help transfer weight from your double top plate down into your header. These headers are typically double or triple 2 by material depending on your wall thickness, 2 by 4 or 2 by 6, and then they'll have plywood in between. If it's a 2 by 6 wall, you'll have two pieces of plywood sandwiched between three 2 by material. This is common header sizes. This isn't always the case depending on your situation, but this is a good general basis. If you have less than a 3-ft opening, two 2 by 4s or 2 by 6s, 16 ft or larger like a garage door, you're going to want to go with an LVL. You can also use 2 by material, but typically these end up being way thicker than your walls. Always check your architect's plans to be sure that you're using the right size lumber for your project. Common roofing material for older homes is slats. Pole barns and a lot of structures not in the US use purlins. Most common in the US is plywood or OSB. When live and dead loads are applied to your roof, it goes down your rafters into the top plate, through your cripples, into your header, down your jack studs, and into your footings. This is how the weight is transferred from up here all the way down to the ground. Let's see what happens when we apply a load with a header. As you see here, deflection of the top plate is assisted by this header here, transferring the weight down into the footing. Let's see what happens when loads are applied without a header.
