Stud Spacing Calculator: Wall Stud Count & Position Layout
Generate a practical wall-stud position schedule from the wall length, selected spacing and end conditions. The layout shows every stud position rather than returning only a piece count.

How the stud spacing calculation works
The layout starts at one wall reference point and places studs at the selected spacing until the final wall end is reached. When the wall length is not evenly divisible by the spacing, the last bay is shortened so the end condition can still be satisfied.
End-to-end layout = regular positions + final wall-end position
Final bay = wall length − last regular stud position
Why the position schedule is useful
A piece count alone does not tell a framer where to mark the wall. The schedule gives the actual centerline positions, making it easier to transfer the layout to plates or a drawing.
When the wall does not divide evenly
For a 4.8 m wall at 0.4 m spacing, the wall divides exactly. A 4.95 m wall at the same maximum spacing would require a final 0.15 m adjustment if a stud is required at the far end. That shorter final bay is shown separately.
Openings and special framing
Door and window openings generally require additional framing members and can change ordinary stud positions. This simple layout should therefore be treated as the base run only, not as a complete wall-framing schedule.
Frequently Asked Questions
Does this tell me the correct structural stud spacing?
No. Enter the spacing required by your project design, framing system or applicable requirements.
Are positions measured from the wall end?
Yes. Position 0 is the start reference and the final position reaches the wall end when the end condition requires it.
What does the final bay mean?
It is the distance from the last regular stud to the end stud.
Can I use feet or inches?
Yes, as long as wall length and spacing use the same basis.
