This simple guide will explain how to measure up for a garden gate.
The most common garden gates that are installed / replaced are closeboard garden gates that are approximately 6′ in height.
However, no matter which height the gates are, there is a standard formula for measuring your gates.
As per the diagram below, a garden gate will comprise of two posts and the gate itself:
The Gate Measurement
If you have an existing garden gate, the simplest thing to do is measure it. Measure in millimetres the height and the width.
Should your gate have an arched top, measure the height at the side of the gate (the lowest point) and in the middle of the gate (the highest point).
The width of a single gate will usually range from 900mm (approx. 3′) to 1,200mm (approx. 4′).
The gate will normally have a gap of 10-15mm either side to allow the gate to freely shut. Do not include this gap as part of the gate measurement.
All gates require two posts. These are often referred to as the hanging post (the post that the gate hinges on), and the slamming post (where the gate shuts). These will often need replacing along with the gate and can be a combination of:
Wooden posts concreted into the ground.
Concrete posts concreted into the ground.
A post attached to a building (often the house or garage). These are referred to as wall plates and are usually bolted into the building.
All gates will include:
Slide bolt (this is optional, but almost every gate installed has at least one, and sometimes two for extra security)
Optionally a key lock system can be fitted (one designed for outside use).
Gate Replacement Reasons
The most common reasons that a gate needs replacing are as follows:
The posts are rotten or are no longer truly vertical (making the gate difficult to operate).
The gate furniture (e.g. the hinges, latch and slide bolt) have aged or are beyond repair.
The entire structure has reached the end of its useful life.
How Long Will A Gate Last
There is no easy answer as there are many factors at play, but the most common are:
How often the gate is used.
If the gate is treated with care.
You should expect a minimum of five years use from a gate, although many gates will last well in excess of ten years.
