Fence Material Calculator — Posts, Rails, Pickets & Concrete

Turn a fence run into a planning list for sections, posts, rails, pickets or panels, gates, concrete, and cost.

Calculated and reviewed by HomeTaskKit Editorial Team ·
Quick answer

Fence materials depend on total run, maximum post spacing, corner and end posts, gates, rails, picket spacing or panel width, and post-hole concrete. Property lines, utilities, wind loads, and local code take priority.

Your planning estimate16 posts + 200 pickets

13 sections, 26 rails, 32 concrete bags, and 1 gate(s).

Formula: run length ÷ section spacing; posts = sections + ends + gate posts

  • Concrete mix32 bags

You must choose post size, depth, spacing, footing, gate hardware, and wind/load design from product instructions and local code.

Use it well

Step by step

  1. 1

    Map each straight run, corner, end, and gate location before calculating sections.

  2. 2

    Use the permitted maximum post spacing and the actual panel or picket dimensions from the selected system.

  3. 3

    Verify utility markings, setbacks, footing depth, concrete yield, and permit requirements before ordering or digging.

Worked example

Check the estimate before you buy

Convert fence run length into sections, posts, rails, pickets or panels, gates, concrete bags, and an editable budget.

Example

A 100 ft run at a maximum 8 ft section length creates 13 sections and at least 14 line/end posts before additional gate posts. Actual layout should mark corners and gates individually.

How the calculation works

Run length is divided by the target maximum section length and rounded up. Posts include ends and gate allowances; rails, infill, and concrete scale from sections and posts.

Planning checklist

Before you place the order

  • Draw corners, ends, grade changes, and gates before ordering.
  • Use actual picket width, gap, and panel width.
  • Choose post size, depth, footing, hardware, and wind design from code and product documentation.
Common questions

Fence Material Calculator — Posts, Rails, Pickets & Concrete FAQ

Should I buy exactly the calculated amount of fence materials?

Usually no. Cuts, spillage, breakage, uneven surfaces, batch matching, and package rounding can increase the order. Use the editable allowance and confirm the product label.

Why does the result round up?

Stores sell full bags, boxes, cans, rolls, panels, or pieces. The tool keeps the mathematical amount visible, then rounds the purchasing quantity up separately.

Does the tool tell me how deep posts should be?

No. Post depth and footing depend on fence design, height, soil, frost, wind, product instructions, utilities, and local code.

Are corner posts counted?

The quick run estimate counts sections, ends, and gates. Complex layouts should be broken into runs and corner posts verified on a drawing.
