How Many Studs for a 24x24 Garage?

How that number is worked out

These are the figures this page was built with and every line the calculator produces from them. Change anything above and all of it moves.

Stud spacing compared

The same 96 ft of garage wall at four spacings. This is the scale where the spacing genuinely changes the order, and the last column is there to show what it does not change.

What else matters here

Ninety five studs for the two car garage everybody builds, framed with a single 16 ft overhead door in one wall.

The door is the part worth understanding, because it is the biggest opening most people ever frame. It takes 33 ft of header stock, which is two plies long enough to span 16 ft plus 6 in of bearing at each end, and that header carries everything above it across a gap wide enough to drive through. It sits on a jack stud at each side, and a full height king stud outside each jack ties the assembly into the plates. Two kings and two jacks, four studs, which is what the king stud and jack stud questions are really asking.

Here is the part nobody expects. Making the door wider does not change the stud count. An 8 ft door and an 18 ft door both leave this wall at 95 studs, because a wider opening deletes more field studs and adds exactly as many cripples above the header to replace them. What changes is the header: 17 ft of stock for an 8 ft door against 37 ft for an 18 ft one, and a header that long is not a pair of ordinary boards. Size it properly, because it is the one member in the building where getting it wrong is not a material list problem.

What this calculator assumes

• Studs are counted position by position: the field studs at your spacing, minus the positions the openings take out, plus the cripples that go back above and below them, plus two extra at every corner and every partition tee, plus a king and a jack on each side of every opening.
• A corner is counted as three studs and a partition tee as three, which is the traditional way. A California corner or a ladder tee uses two plus blocking and saves a stud at each one.
• Cripples are counted as whole studs because they are cut from stock. If you are nesting cuts carefully you will use fewer, and the waste line is where that shows up.
• Plates are one bottom plate and a double top plate, so three times the wall length, and they are priced in 16 ft lengths.
• Headers are figured two plies deep at the opening width plus six inches of bearing. Span, load and species decide the header depth, and that is an engineering question rather than a takeoff one.
• The rule of thumb line is the old one stud per foot of wall at 16 inches on center. It is there as a sanity check, not as the answer.
