Do I need a header on a non load bearing wall?
A doorway in a non-load-bearing wall doesn’t need a structural header. You’ll place just one or two 2x pieces of lumber flat across the top of the opening. This framing lumber is used to support the finished wall material and provide solid nailing for any trim around the door.

How far can a double 2×4 header span?
An interior 2×4 beam – made up of two 2x4s nailed together – can span up to 3′ 1” without support beneath a set of joists for a home no greater than 20′ wide and supporting no more than 1 floor. For homes that are 28′ wide, a double 2×4 can support a span of 2′ 8”.
How do you calculate header size?
It went like this: Measure the span in feet and add 2 to that number. The sum will be the height of your double header in inches. For example, if the span is 4 feet, add 2 to 4 for a sum of 6. Therefore, the header would need to be made from doubled 2x6s.
What size wood do you use for a window header?
Several code-approved options beyond the standard double 2×12 save material and energy. Synopsis: Double 2×12 headers are still the standard for window and door openings, even though the IRC lists other options for headers that save lumber, minimize thermal bridging, and save space for insulation.

A bottom plate can be nailed down into the stud whereas a header would have to be toe-nailed. So it is easier to construct with a bottom plate. Structurally, it is not required.
Is a king stud necessary?
King Studs
A header needs a full or king wall stud on each side of the opening, extending from the bottom wall plate to the top wall plate. These can be regular studs or special studs added if the regular spacing doesn’t conform to the door opening.
Do you need a jack stud?

Window and door openings should have no more than one pair of king studs, one pair of jack studs, and the minimum number of cripple studs needed to maintain on-center spacing of studs.
How much weight can a jack stud hold?
So, to answer your question: the maximum load for your 2×6 jack stud (I call them trimmers) is: 1320 x 1.5” x 5.5” = 10,890 lbs. However, it sits on a plate and the header sits on it in perpendicular compression, so the maximum load it can support without crushing the plate is: 425 x 1.5” x 5.5” = 3,506 lbs.
