It does not stop at a number.

16 in on centerwall lengthlength / spacing + 1, then corners, tees, kings, jacks and cripples
The rule of thumb, length divided by spacing plus one, gets the field studs and nothing else. Every corner, every tee, and every opening adds framing that the rule of thumb misses, which is why the page shows both numbers.

Wall length compared

The short end of the range, where the corner and tee studs are most of the wall. Watch the last column, which is the one stud per foot rule of thumb. It is under on every row here, by more than half at the top of the table and closing up as the wall gets longer.

What else matters here

Thirteen studs, and the interesting part is that only seven of them are field studs, the ones marching along at 16 in on center. The other four are the pairs that make up the corners at each end.

That is why the old one stud per foot rule gives 8 here and is badly wrong. The rule is really a statement about field studs, and on a short wall the field studs are barely half the count. The shorter the wall, the worse it gets. At 3 ft the rule says 3 and the real answer is 8, because the corners do not care how long the wall is.

It is worth being clear what an 8 foot wall means, because the phrase is used both ways. This page is a wall 8 feet long, standing 8 feet tall, which is the standard height and the reason the question sounds ambiguous in the first place. If what you have is a wall of some other length that happens to be 8 ft tall, change the length at the top and the height stays where it is.

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.

Questions people ask

How many studs in an 8 foot wall?

13 at 16 in on center, with a ten percent waste allowance. Seven are field studs and four make up the two corners.

Why is it not 8 studs, one per foot?

Because that rule only describes the field studs. The corner and tee studs are on top of it, and on a wall this short they are nearly a third of the total.

Does 8 foot wall mean 8 feet long or 8 feet tall?

People use it both ways. This page is 8 feet long and the standard 8 feet tall. Change the length field if you meant a different length.
