Whatever the style, every fence estimate starts the same way. Measure the run, count the sections, then size the parts for the material you have chosen. Here is the method.

1. Measure the run

Walk the line and total the length in feet. For a yard with corners, measure each straight stretch and add them up. Note where gates go and how wide each one is, because you do not clad a gate opening.

2. Count posts and sections

Divide the run by your post spacing and round up to get sections. Posts are one more than sections. Add a post for each gate. This step is identical for wood, picket, vinyl and chain link, only the spacing changes (8 ft for wood and vinyl, up to 10 ft for chain link).

3. Size the cladding for your style

This is the only part that differs by material:

  • Wood and picket: rails per section by height (2 at 4 ft, 3 at 6 ft, 4 above), then pickets by dividing the fenced length by picket width plus gap.
  • Vinyl: one panel per section, less one panel for each gate.
  • Chain link: top rail and mesh by the linear foot of fenced run.

4. Add concrete and hardware

Every post needs concrete: roughly a cubic foot or more per hole depending on size. Add a hinge-and-latch kit for each gate, plus the small fittings each style needs.

5. Add a margin

Order 5 to 10 percent extra cladding for waste and breakage, and round concrete bags up. The spare costs little and saves a return trip.

Do it in one place

The fence material calculator runs this method for any style, pick the material and it shows only the parts that apply. To plan a full yard with corners and gates, the fence drawing tool totals everything from your drawing.

Frequently asked questions

What is the first step in estimating a fence?
Measure the total run length and decide your post spacing. Sections equal the run divided by spacing, rounded up, and almost everything else follows from the section count.
Do all fence types use the same maths?
The post and section count is the same for every style. What differs is the cladding: wood and picket use rails and pickets, vinyl uses panels, chain link uses linear rail and mesh.
How much extra material should I buy?
Add about 5 to 10 percent for waste, off-cuts and the odd damaged board, and round bags of concrete up. It is cheaper than a second trip to the yard.
