Framing a wall? Enter the wall length to estimate the number of studs at standard 16-inch on-center spacing.

Estimating studs

At 16" on center, studs run about 0.75 per linear foot, plus one to finish the wall — and extra for corners, openings and blocking. Don't forget top and bottom plates (the horizontal members) when buying lumber.

Frequently asked questions

How many studs do I need for a wall?

At 16-inch spacing, roughly (wall length in inches ÷ 16) + 1, plus extras for corners and openings.

Is 16 or 24 inch stud spacing better?

16-inch is standard for load-bearing walls; 24-inch can work for some non-load-bearing walls and saves lumber.
