How this calculator works
Count posts, rails, and pickets for a fence run. Planning estimates only — verify measurements and local codes on site. Posts = ceil(length ÷ spacing) + 1; pickets = length ÷ picket width. Example: 100 ft fence, 8 ft post spacing, 6 ft height → 14 posts + ~180 pickets.
Posts = ceil(length ÷ spacing) + 1; pickets = length ÷ picket width.
Example: 100 ft fence, 8 ft post spacing, 6 ft height → 14 posts + ~180 pickets.
When to use this Fence Materials Estimator
Common use cases
- Count posts, rails, and pickets for a fence run.
- Sanity-check with this case: 100 ft fence, 8 ft post spacing, 6 ft height → 14 posts + ~180 pickets.
- The relationship is: Posts = ceil(length ÷ spacing) + 1; pickets = length ÷ picket width.
Localized examples
- Roofing & Exterior: the example on this page uses the same formula as the widget.
What you get
- Fields: Fence length (ft), Post spacing (ft), Picket width (in), Fence height (ft)
- Posts = ceil(length ÷ spacing) + 1; pickets = length ÷ picket width.
- Example on the page: 100 ft fence, 8 ft post spacing, 6 ft height → 14 posts + ~180 pickets.
How to Calculate Fence Materials Estimator Step-by-Step
- 1Enter Fence length (ft), Post spacing (ft), Picket width (in), then the remaining fields. Use the values you have, not a catalog average, unless that is all you know.
- 2Posts = ceil(length ÷ spacing) + 1; pickets = length ÷ picket width.
- 3Worked case: 100 ft fence, 8 ft post spacing, 6 ft height → 14 posts + ~180 pickets.
- 4Buy materials after you walk the job. This is a first-pass quantity, not a purchase order.
Governing formula
Posts = ceil(length ÷ spacing) + 1; pickets = length ÷ picket width.
100 ft fence, 8 ft post spacing, 6 ft height → 14 posts + ~180 pickets.
Example: set Fence length (ft) = 100, Post spacing (ft) = 8, Picket width (in) = 5.5, then read the result.
