Most framing calculators count studs and stop. The plates run the full length of the wall twice — three times if the top plate is doubled — and on a typical wall that is a third of the timber. This counts the lot.
Enter the run and the spacing. You get the stud count, and then the plates and noggins that go on the same order.
Works in metric and US imperial — you choose at the start and can switch at any time. Every figure this calculator uses is published with its source, and the result comes with a printable order sheet. No account, no email, and nothing you type leaves your browser.

Most framing calculators count studs and stop. But the plates run the full length of the wall twice — three times where the top plate is doubled — and on a typical wall that is about a third of the timber on the order. This page gives you the studs, then the plates and noggins that belong on the same delivery, so there is one trip rather than two.
A door or window takes king studs full height each side, jack studs supporting the header, and cripples above and below. That is why an opening adds timber rather than saving it, and why we allow several pieces per opening rather than subtracting the studs the opening removes. Noggins go where the board edges are, so plan the plasterboard layout first — a horizontal board joint with no timber behind it will crack, and moving it afterwards means taking the wall apart.
Sight every stud before you fix it: a bow can be worked around by putting the crown up consistently, but a twist cannot, so reject twisted timber at the yard rather than at the wall. And use treated timber for a sole plate on a solid floor — any timber in contact with concrete or masonry wants to be treated, ideally on a DPC strip, because untreated softwood on a slab will take up moisture.
Top and bottom plates running the full length of the wall — twice, or three times with a doubled top plate — plus noggins, and extra pieces at every opening. On a typical wall the plates alone are about a third of the timber.
King studs running full height each side, jack studs supporting the header, and cripples above and below. An opening adds timber to the order rather than saving it.
No. 16 inches is 406 mm — close enough to matter but not the same, and sheet materials differ to match. Metric and imperial framing are two systems, so stay in one of them for the whole job.
On a solid floor, yes. Any timber in contact with concrete or masonry should be treated, ideally sitting on a DPC strip. Untreated softwood on a slab will take up moisture from below.
