How wall frame positions are worked out
When several frames go up in a row, the gap is usually found to be off only after the nails are already in the wall. This tool takes the wall width, the number of frames and their widths, and the side clearance you choose, then returns the left edge, center and right edge of every frame in inches. You can enter the gap between frames yourself or let the leftover width be shared evenly between them.
What the math assumes, and rounding
Frame width is measured across the outer edge of the frame, and side clearance is per side, not both sides together. Every length is snapped to 0.1 in before the math runs, so the one-decimal figures on screen match the values actually used. An evenly shared gap is snapped the same way. Nail height is the center height you entered, plus half the frame height, minus the top-to-hanger distance.
Limits and disclaimer
As of October 2026, no official standard for how high a frame should hang has been confirmed in authoritative sources. No recommended hanging height is therefore offered, and the center height is yours to set. Fixing methods and load limits for different wall materials are not covered. For nails and anchors, follow the product sheet and the manufacturer's guidance first.
Frequently asked questions
No officially recommended height is offered here. Widely quoted figures exist, but they are common practice rather than a published standard. Enter the center height you want and the tool works out only the nail position.
The wall width minus the side clearance and the total frame width is divided by the number of gaps between frames. If that comes out negative, the frames do not fit and a message says so.
They are measured from the left end of the wall, treated as 0 in. Each frame shows its left edge, its center, and its right edge.
