The calculation, without hidden assumptions
Fence takeoffs vary sharply by style. A panel fence, a rail-and-picket fence and a wire fence do not share the same bill of materials. This calculator focuses on the geometry common to many straight runs, then keeps panel width, rails per bay and picket density editable so the estimate can match the chosen system.
How to use this calculator
Enter the total fence run and subtract any gate openings by entering their combined width.
Set the target post spacing and add any extra corner/end posts needed beyond one straight run.
If relevant, enter panel width, rails per bay or pickets per linear foot to build a more complete material tally.
Where people use it
- •Straight-run privacy fence planning
- •Panel-count comparisons
- •Early post, rail and picket takeoffs
Example: 100 ft straight run
With a 4 ft gate, 96 ft remains for infill. At an 8 ft target spacing that is 12 bays and 13 posts for a simple straight run before adding any special corner, brace or gate posts.
What the result does not assume
- •Corners, slopes, bracing, gate hardware, terminal-post rules and structural requirements differ by fence system. Enter extra posts and verify the manufacturer or project detail.
- •Post spacing is a planning input, not a code or structural recommendation.
Frequently asked questions
Are gate posts included automatically?+
Gate width is removed from infill length, but special gate/brace posts vary by system. Use the extra-post field for your detail.
Can I use this for panel fencing?+
Yes. Enter the actual panel width and the calculator returns whole panels in addition to bays and posts.
What if my fence has several corners?+
The geometry here treats one total run. Add the corner/end posts required by your layout and verify each segment separately when spacing must land exactly.
