Fence layout
Picket Spacing Calculator
Lay out a fence run with equal picket gaps. Enter the clear run, picket face width, and target maximum gap; the result gives a practical count and equal final gap.
How the estimate works
Use the number as a planning starting point.
The calculator finds a whole picket count that keeps the equal gap at or below the target maximum, then reports the exact gap and center-to-center layout distance.
Check the result
Wood movement, picket variation, posts, gates, and local fence details may require small field adjustments. Confirm the first and last picket positions before fastening the whole run.

FAQ
Common Picket Spacing Calculator questions
How do I make fence picket gaps equal?
Use the total clear run and solve for an integer picket count, then use the resulting equal gap as a spacer or layout mark.
Should pickets touch?
That depends on the fence style and wood movement. Follow the project design and account for seasonal expansion.
