Find a whole picket count, the actual gap, and center-to-center spacing for a fence run.
Use this calculator when you want a repeatable picket layout across a straight fence run. It finds a whole picket count first, then shows the gap that count creates so you can check the result.
The picket count is rounded up from the usable run, picket width, and maximum gap. The actual gap is then recalculated from that whole count.
A 96 inch run with 3.5 inch pickets and a 2 inch maximum gap produces 18 pickets and an actual gap of about 1.94 inches.
Leave room for posts, rails, end setbacks, and gate openings before treating a run as a finished picket field. Confirm the real picket width, not only the nominal name.
Picket width, rounded edges, post layout, decorative patterns, slopes, and end details can change the practical spacing. Use the result as a straight-run layout check.
This does not lay out posts, rails, caps, gates, slopes, or decorative patterns. Check the final design against the fence system and local requirements.
No. Measure the usable picket field. Remove the space taken by posts, gates, and end setbacks before entering the run.
The tool rounds up to a whole number of pickets. The remaining space is then divided evenly across the gaps.
You can enter a limit from your plan or local requirement, but confirm the final fence design with the authority or professional responsible for it.
Short, practical help for the next step in this project.
