How many studs do I need for a 12 foot wall?

A 12 ft wall at 16-inch spacing needs about 10 studs plus plates and extras — the calculator adds doors, windows, corners and a 15% waste allowance.

Should I use 16 or 24 inch stud spacing?

16-inch spacing is standard for load-bearing walls and gives a stiffer wall; 24-inch saves lumber on non-bearing walls but check your local code.

Order 15% more studs than the exact count — you'll cull crooked ones at the yard and lose some to cuts around openings.

Pick your lumber — the math adjusts.
