How to Measure Wooden Bifold Entrance Gates

How to measure for bifold gates

Take 3 measurements between the posts. Across the top, middle and bottom. Make note of the smallest measurement.
The reductions you need to make depend on the style of bifold gate you have and how you are going to mount the hinges; on the back of the posts or in-between them.
For the bifold gates, you just need to know the width of your gate to know whether you need smaller than 1500mm hinges or the greater than 1800mm hinges.

Are you mounting your hinges on the rear of the gate post?

With this option, your hinge plates are mounted on the rear face of the post with the back edge of gate sitting flush with the back edge of the post. This mounting will mean your gate opens towards the driveway.

For a 3 leaf gate, reduce 50mm from your lowest measurement.
For a 4 leaf gate, reduce 60mm from your lowest measurement.
For a 5 leaf gate, reduce 70mm from your lowest measurement.
