Choosing the perfect wrought iron gate starts with accurate measurements. Whether you’re replacing an existing gate or installing a completely new entrance, getting the measurements right ensures a smoother installation process, better functionality and a professional finish.
At DJ Haney Blacksmiths, we manufacture bespoke wrought iron gates tailored to each property. This guide explains the key measurements you’ll need before requesting a quote or arranging a site survey.
Before You Start
Before taking measurements, it’s important to decide:
- Where the gate will be positioned
- Whether it will be a single or double gate
- If the gate will be manual or automated
- Which direction the gate will open
- Whether there are any slopes or obstructions nearby
You’ll also need:
- A tape measure
- Pen and paper or phone notes
- Someone to help for larger openings
Measuring the Width
The width is the most important measurement.
Measure the distance between existing brick pillars, fence posts, walls, or the proposed gate posts location.
Take measurements in three places – top, middle and bottom. This helps identify if the opening is uneven.
Use the smallest measurement when providing dimensions.
Example:
Top = 3010mm
Middle = 3000mm
Bottom = 2995mm
You would use: 2995mm
Measuring the Height
Next, measure the desired gate height. This is usually taken from ground level to the top of the proposed gate.
When measuring height, consider privacy requirements, security needs, local planning restrictions and matching existing railings or fencing.
Common residential gate heights include 900mm, 1200mm and 1800mm.
However, bespoke gates can be manufactured to almost any size.
Check the Ground Levels
Ground levels are extremely important for gate installation. If your driveway slopes inward, outward or sideways, this can affect gate opening clearance, hinge positions, automation options and gate style suitability.
Measure:
- Any rise or fall across the opening
- The amount of clearance available underneath the gate
Photos of the area can also help fabricators understand the site conditions
Consider Gate Opening Space
Make sure there is enough room for the gate to open fully.
For swing gates, check for walls, cars, plants or steps that may obstruct movement.
For sliding gates, ensure there is enough side clearance for the gate to slide open.
If space is limited, bi-fold or sliding gate systems may be recommended instead
Measuring for Existing Gate Replacements
If replacing an old gate:
- Measure the opening width, not the existing gate itself
- Check whether the posts are still level and secure
- Inspect hinges and fixing points
Sometimes, older gates may have been manufactured undersized to compensate for movement over time, so relying solely on the old gate dimensions can cause issues.
Automated Gate Considerations
If you’re planning automated gates, additional space may be needed for motors, underground automation systems, control boxes and safety sensors. Power supply location should also be considered during the measuring stage
Helpful Photos to Provide
When requesting a quote, photos are extremely useful. Try to include:
- A straight-on photo of the opening
- Photos from both sides
- Images of the driveway or surrounding area
- Close-ups of pillars or posts
- Any slopes or obstacles
This helps fabricators recommend the best gate style and installation method.
Common Measuring Mistakes to Avoid
- Measuring only once – Always double-check measurements to avoid costly mistakes.
- Ignoring ground slope – Even small slopes can affect gate operation.
- Forgetting clearance – Gates need space underneath and around them to open properly.
- Measuring the old gate instead of the opening – The structural opening is what matters most.
Why Professional Surveys Matter
While taking initial measurements is helpful, professional site surveys ensure complete accuracy before manufacturing begins.
At DJ Haney Blacksmiths, we carry out site visits to:
- Verify measurements
- Assess ground conditions
- Recommend suitable gate styles
- Discuss automation and security options
- Ensure the installation works perfectly with your property
This helps avoid delays, fitting issues and unexpected costs later in the project
