How to Choose the Right Sliding Gate for Your Property
Thinking about installing a sliding gate to update your entrance, save space, or add security to your home? This guide walks you through how to measure for a sliding gate step by step, highlights common mistakes to avoid, and helps you select the best option for your outdoor space.
1. Measure the Width Between Gate Posts
Measure the inside distance between the two gate posts at three different heights:
Why three measurements? Posts aren’t always perfectly parallel—especially on older installations or where settling has occurred over time.
Record the smallest of the three measurements—this is the usable width for your sliding gate.
If the difference between measurements is more than 1 cm (about 3/8"), check the alignment of your posts before installing. For example: if you measure 3.03 m at the top, 3.01 m in the middle, and 3.02 m at the bottom, use 3.01 m as your reference width.
2. Measure the Height from the Ground to the Underside of the Post Cap
Next, measure the total available height from the finished ground level up to the underside of the post cap (or cover).
- • Measure on both sides, as the ground may slope slightly.
- • The final gate height should be 2–4 inches (5–10 cm) less than the available height to allow clearance for hinges and smooth operation.
Make sure there’s enough space for the rack and gate motor if you’re installing an automated system.
3. Plan for Side Clearance
A sliding gate opens to the side, so you’ll need enough space on one side of the opening.
Clearance = gate width + at least 20 inches (50 cm).
This extra space is needed for the rack, motor (if automated), and end stops.
4. Check Ground Level and Alignment
Before installing a sliding gate, make sure the ground is level and solid. If the surface isn’t flat, the gate may drag, get stuck, or wear out faster.
The ground should be firm, with no holes or bumps—even small uneven spots can cause issues. If needed, pour a straight concrete pad (called a threshold) along the full width of the opening.
If your driveway slopes, consider a cantilever gate (which doesn’t require a ground track) or adjust the concrete to level it out. Before installation, always check with a laser or bubble level to ensure everything is straight—this helps your gate slide smoothly and last longer.
Summary:
Measure the width between posts at the top, middle, and bottom. Use the smallest value.
Measure the gate height from the ground to the post cap.
Allow for side clearance at least equal to the gate width plus 20 inches (50 cm).
Check that the ground is flat and stable. Install a concrete threshold if needed.
If you’re unsure, consult a professional for on-site measuring—this ensures the best possible result.

An aluminum gate is known for its outstanding durability and can easily last over 20 years with minimal maintenance. Aluminum naturally resists rust and weathering, so it holds up well over time without the need for extensive upkeep compared to other materials.
A sliding gate offers several key benefits over a swing gate. It requires less clearance, as it moves sideways along a track, making it a great choice for sloped driveways or entrances close to the street. Sliding gates are also well-suited for smaller outdoor spaces and are easier to automate, providing added convenience for everyday use.
Maintaining an aluminum sliding gate is straightforward. Clean it regularly with warm water and mild soap to keep its appearance and function in top shape. Periodically check the guide rails and rollers to make sure the gate slides smoothly. Since aluminum is naturally resistant to rust, you don’t need any special treatments, unlike iron gates that require more frequent care.
Yes, the Arles sliding gate is compatible with a wide range of accessories to enhance your setup. You can pair it with a matching pedestrian gate from the same collection for a coordinated look, and add a gate opener designed for sliding gates. Matching aluminum posts and safety accessories like photoelectric sensors can also be included to suit your needs.
