Choosing the Right Gate Width for Your Driveway
Why Gate Width Matters
This driveway gate sizing guide will help you choose the right aluminum driveway gate width — whether you're installing a residential, commercial, or industrial gate. Understanding how gate width is defined ensures a smooth installation and proper fit. We’ll also show you how to measure for a driveway gate using industry-accepted best practices.
Understanding GreatFence.com Gate Widths
At GreatFence.com, gate widths are defined by the distance between the two gate posts — commonly referred to as the Daylight Opening (DLO).
This measurement includes the spacing required for hinges and the locking mechanism. Gate widths do not include the physical posts themselves.
We fabricate single gates up to 10 feet wide and double gates up to 20 feet wide. All gates are made-to-order and custom-sized to your project specifications, including residential driveway gate width configurations.

Below is a visual representation of how gate widths are measured on GreatFence.com. These diagrams help clarify the DLO (Daylight Opening) — which equals your true gate width.

How to Measure Your Driveway for a Gate
- Measure the exact distance between your two gate posts or planned post locations.
- Do not subtract for hinges or locks — we make those spacing deductions at the factory.
- For uneven or sloped driveways, refer to our gate slope guide or contact us for assistance.

What If I Order the Wrong Size?
Since all gates are custom fabricated per order, they are non-returnable. That's why it's critical to measure correctly before placing your order.
