Outback Picket installation: height, spacing and ground

Build with careMeasurement guide3 minute read

The length on the picket label is not the height of the finished fence. Start by separating what stays above ground from what goes into it.

The short answer

Total picket length equals above-ground height plus embedment. Then check the usable fixing holes, mesh height and intended post spacing. Those measurements must work together; buying a taller post alone does not settle the design.

1.80m total in this illustration.
Not a recommended embedment.

Illustrative dimensions only. Required embedment depends on soil, post and fence design; 0.60m is not a universal recommendation.

Do the height check on paper first

Total length − embedment = height above ground

Illustration: 1.80m − 0.60m = 1.20m. This explains the arithmetic, not a universal embedment depth.

Suppose your planned mesh and any separate top wire need more usable fixing height than that example leaves. You need to revisit the post length or design before ordering. Do not assume the very top of the post is an available fixing position: check the hole-spacing drawing and the fixing arrangement.

Ground levels also change along a run. A picket installed to a consistent exposed height can still leave a gap under the mesh at a hollow. Walk the bottom edge, not just the top line.

Keep picket spacing separate from mesh spacing

A mesh code ending in 15 describes vertical mesh stays 15cm apart. It does not mean your steel posts are 15cm apart. Steel-post spacing is a separate layout decision based on the fence system, ground and expected loading.

Three measurements that answer different questions
Measurement What it tells you
Picket length Total length of the steel post being bought
Picket spacing Distance between line supports along the fence
Mesh stay spacing Distance between the upright wires within the mesh

For ordering, calculate each uninterrupted run separately and count strainers as assemblies, not ordinary pickets. Spares created by a pack purchase should be shown separately from the number installed.

Check the ground and the equipment

  1. Locate the services

    Use the appropriate service-location process before driving posts or digging. Do not rely only on where you remember an old pipe being.

  2. Match the driver to the section

    Check that the driving equipment suits the picket and follow its instructions. Inspect the equipment and post for damage.

  3. Stop at an unexpected obstruction

    Do not make repeated force your default response to rock, a buried object or a damaged post. Reassess the location and installation method safely.

Do a first-run check before repeating the setup

A short initial check with the actual post, mesh and fixing is more useful than discovering a hole-position conflict after hundreds of posts are in. This is a compatibility check; it does not replace the installer’s assessment of the ground.

Before you leave this guide

Pick the height and section for the job, then verify the fixing positions. Keep the below-ground requirement visible in the plan instead of treating it as leftover length.

Check height, section, finish, fixing details and the quantity on each single or pack listing.
