How to Measure Your Driveway for an Electric Sliding Gate

t292-0

To measure your driveway for a sliding gate, record the full clear opening width, the height from the ground to the top of the gate, and the ground conditions along the track path. Add space for the track, the stopper at each end and any slope or obstacles, then send these figures with photos so we can plan the exact gate length and drive system.

Why the Measurements Matter Before Anything Else

A sliding gate runs along a track, so its length depends on how much space it needs to open and close fully. Measuring correctly at the start prevents a gate that is too short for the opening or too long for the space beside the wall. The measurements also decide which drive unit is suitable and how the track is set into the ground.

Take the figures on a dry day, when the ground and the entrance are in their normal condition. Note any changes you plan to make later, such as a new paving layer, because they affect the final height.

Measure the Opening Width and Gate Length

Measure the clear opening between the two posts or walls, from inside face to inside face. Then measure the space on the side where the gate will slide, because the gate must travel beyond the opening so it clears the gap when fully open. Mark the travel distance on the ground with a string or tape.

Check Height, Ground Level and Slope

Measure the height from the finished ground to the top of the required gate, and note whether the driveway is level or sloped. On a slope, the track may need to follow the ground line, and the bottom of the gate must keep a safe clearance above the surface. Check for kerbs, drains, roots or pipes along the track path, since these can change where the track is laid.

Exact values for clearances are confirmed by the engineer during the visit, so do not rely only on a rough estimate.

Allow Room for the Track, Stoppers and Drive Unit

The track sits in the ground or on a surface frame, and it needs room at both ends for the stoppers that define the open and closed positions. Ask where the electric drive unit will be mounted, because it needs a solid base and access for maintenance. Leave space for cables from the power point to the operator.

Consider the swing of the gate's leaves on the other side of the entrance if you have a swing gate option, and check that nothing blocks the path, such as plants, a utility box or a parked car.

From Site Visit to Drawing and Approval

After you send your photos and figures, we arrange an on-site measurement to confirm the numbers. The team then prepares a drawing and a written specification that shows the gate size, the track layout, the drive position and the finish. You review the drawing and approve it before any work starts.

Once approved, the gate is manufactured to measure in our factory on Rival Street, then finished with hot-dip galvanizing and powder coating. Installation follows, and the drive and controls are tested together.

Tips for a Smooth Installation Day

Clear the work area before the installers arrive, and make sure the power supply is ready at the planned point. Confirm the final track position with the installer while the ground is still open, because changes are simpler at that stage. Keep the measurement notes and drawing together so future maintenance and any extension work can follow the original plan.

Frequently asked questions

What is the most important measurement for a sliding gate?

The clear opening width is the key figure, together with the free space on the sliding side. These two numbers together determine the gate length the track must cover.

Do I need to measure the slope of my driveway?

Yes, because a slope affects the track layout and the clearance at the bottom of the gate. Note the slope and send photos so the engineer can check it during the site visit.

Can I measure everything myself?

You can take the basic figures yourself, but an on-site measurement by our team confirms them before the drawing is made. This avoids errors that are costly to fix after production.

Where should the electric drive unit be placed?

The drive is usually mounted on a solid base beside the track, with access for maintenance and a nearby power point. The exact position is agreed during the drawing and approval stage.

Common mistakes to avoid

The most common mistake is measuring only the opening and forgetting the travel space on the sliding side. Also avoid ignoring the slope or the drive unit position, since both can require changes after the gate is already made.

Our recommendation

Measure the clear opening, the free sliding length, the height and the ground slope, then take clear photos from both sides. Send these figures early so the drawing and the track layout can be agreed before any concrete or paving work begins.

Summary

Measure the clear opening, the free sliding length, the height and the slope of your driveway before you contact us. Accurate figures let us plan the gate, the track and the drive correctly from the first drawing.
