Step 1: Measure the width

• Measure the full opening top, middle, and bottom.
• Use the smallest of these three measurements.
• This will be your overall opening width.

Step 2: Measure the height

• Decide how tall you want your gate to be.
• Measure from the ground to the required height.
• This will be your overall height.

Step 3: Choosing the correct size Gate Posts

• Selecting the post's width
  • For light gates: Use posts that are at least 100mm square.
  • For heavy gates: Use a minimum of 150mm thick post, for double gates or driveway gates, use a minimum thickness of 200mm.
• Selecting the post's Length
  • A minimum of 900mm (about 3 feet) in the ground is recommended for gate posts.
  • Add 900mm to the overall height measurement.
  • If attaching a post to a fixed object, you do not need to have 3 feet in the ground.

Step 4: Account for obstructions and ground slope 

• Use a spirit level to check if the ground is level.
• If the ground is sloped, you may need to adjust the gate design or install a sloped bottom edge.
• Check for any obstructions that could interfere with the gate's operation, such as overhanging branches or uneven ground. 

Step 5: Subtract for hardware and expansion

• To confirm your physical gate width
  • We recommend subtracting 10mm for hinges and a further 10mm for a latch. This allows for expansion and contraction.
  • Deduct the chosen widths of your gate posts.
  • Your final size will be your physical gate width.
• To confirm your physical gate height
  • We recommend subtracting 10mm for the floor. This allows for expansion and contraction.
  • If the gate is enclosed at the top, we also recommend subtracting 10mm. This allows for expansion and contraction.
  • Your final size will be your physical gate height.

Step 1: Measure the width

• Measure the opening between posts top, middle, and bottom.
• Use the smallest of these three measurements.
• This will be your overall opening width.

• Decide how tall you want your gate to be.
• Measure from the ground to the required height.
• This will be your overall height.
