Tips and Key Steps for Installing Your Gate!

Looking to install a gate to secure your property and enhance your outdoor space? Before you buy, taking accurate measurements is crucial. This guide walks you through how to measure for your gate, choose between a swing or sliding model, and avoid common mistakes.

1. Measure the Width Between the Posts

Measure the inside distance between your two gate posts at three different heights:

A

Top

B

Middle

C

Bottom

Why three measurements? Posts may not be perfectly parallel—especially on older installations or if they've shifted over time.

Record the smallest of the three measurements—this is the usable width for your gate.
If the difference between the measurements is more than 1/2 inch, check the alignment of your posts before installing. For example: If you measure 119.3" at the top, 118.5" in the middle, and 118.9" at the bottom, use 118.5" as your width.

2. Measure the Height from the Ground to the Underside of the Post Cap

Next, measure the total height available from the finished ground level to the bottom of the post cap (or post cover).

• • Take this measurement on both sides, as the ground may slope slightly.
• • The final gate height should be 2 to 4 inches less than the available height to allow clearance for hinges and opening.

Make sure the rack and gate motor will fit without interfering with the gate height.

4. Check That the Ground is Level

The ground should be flat and level across the entire width of the gate.
If there's a slope:

• • You can open the gate outward (if allowed by local regulations),
• • Or choose a custom gate with adjustable hinges or an asymmetrical swing (one leaf narrower than the other).

Pro tip:
Use a spirit level or laser level to spot any height differences.
A slope greater than 3/4 inch per yard can cause issues with gate operation.

In Summary:

Measure the width between your posts at three heights (top, middle, bottom).
Note the available height from the ground to the post cap, allowing a 2 to 4 inch clearance.
Check that the ground is level and the posts are plumb before installing.
Consider gate automation when measuring to avoid surprises during installation.
Choose your gate style to suit your property: swing gates for wide, straight entries; sliding gates for tighter spaces or sloped driveways.

If you're unsure, consult a professional for on-site measurements—it's the best way to ensure a perfect fit.
