A jack stud, also known as a trimmer stud, is a vertical framing member installed on either side of a door or window opening. It is critical for holding up the ends of the header that bridges the gap. King studs run floor-to-ceiling, adjacent to and beyond the length of the jack stud, acting more like a traditional wall stud but usually fall out of the 16-inch spacing. Jack studs are used in conjunction with king studs to support a header above an opening, such as a door or window.
Stud spacing for interior walls tends to be around 16 inches on center, while exterior walls may be up to 24 inches on center. The more load a wall needs to hold, the more stud spacing is required. In one-story buildings, 24-inch spacing of 2×4 studs is acceptable if wall sheathing or siding is of different sizes.
The total number of jack and king studs required at each end of an opening depends on the size of the opening (feet-inches), 24-inch O.C. STUD SPACING, and 16-inch O.C. STUD SPACING. King and jack studs must be the same dimension as adjacent wall studs, and their size depends on the load it carries. Utility-grade studs should not be spaced more than 16 inches on center or support more than a roof and ceiling, or exceed 8 feet in height for exterior walls.
No 36″ door opening needs more than 2×6″s, and more than one jack per side. The only reason people put bigger headers in on small spans is simply to use one jack.

How to measure jack studs?
For exterior doors, measure the width from one jack stud to the other, and the height in three places: the top, bottom, and center. If ordering a front door, interior swinging door, or custom door, you will be asked to measure the “rough opening”. This refers to the framed opening where the door, jamb, and threshold are being installed. It is crucial to get the measurements right, as if not, the door we make might not fit.

What size are exterior studs?
Studs are vertical load-bearing members used to support elements in walls and partitions. In exterior walls of one- and two-story buildings, studs are at least 2×4 inches, with a 16-inch spacing. In three-story buildings, studs in the bottom story are at least 3×4 or 2×6 inches, and may not exceed 16-inch spacing. They are arranged in multiples at corners and partition intersections for rigid attachment of sheathing, siding, and interior wall finish materials.
Nailing strips or metal clips may be used to back up interior finish at corners. A grademark identifies the species, grade, grading agency, and mill number, allowing the product to be traced to the mill of origin and establishing its structural properties. Most 2×4 dimension lumber is visually graded and marked with an ink stamp at the mill, ensuring the product’s strength for the application.

The next jack stud should be cut to the door’s height plus 2-1/2″ and minus the bottom plate’s thickness. The header size is determined by the load it carries. If building a new bearing wall or doorway, consult local building code span charts or an engineer for proper size. The header’s width should fit from king stud to king stud, with jack studs fitting under it to disperse loads. A typical header width with single jack studs is 3″ larger than the rough opening.

This article is educational. But over the years I’ve learned wood framing from older guys that new this of the pre-cut studs at 92-5/8 and there is a reason behind that. You explained it real simple. You ought to make article about installing sheathing and siding. I’ve seen many homeowners who don’t know a thing about sheathing and installing siding for their additions. Ive worked on side-jobs where the home owners didn’t do their work correctly and i just hv to make it work. I save these types of articles to show the youngsters how to do residential framing, drywall, taping, texture and sheathing/siding intall. Im telling you lotta youngsters need to learn the carpenter trade we are a dying breed. Back in the days when i was a younster i believe older more experienced carpenters didn’t teach us these things that were important so i was yelled at a lot. Back then there was no YouTube tutorials.
