If you’re shopping for gates, there’s a good chance at least one person has asked you whether you’re talking about gate size or gate opening size.
If you’re not in the fence business, this might seem like the same thing. However, it’s actually not! Let’s take a closer look at the difference between gate size and gate opening size. In many Phoenix neighborhoods, having a clear understanding of these measurements can help you avoid costly mistakes and ensure your new gate meets local requirements or HOA rules.
Why Does This Matter?
Usually, if you have your gate, gate hardware, and posts on-site at the same time, it doesn’t really matter too much whether your measurements refer to gate size or gate opening size.
It becomes crucial when you must fit a gate into a specific space with limited room. You might also need an exact clearance to fit a large truck, RV, or other equipment, which is common in many Arizona properties. If you need a gate that meets those precise dimensions, you will have to specify whether you’re talking about gate size or gate opening size.
What Is Gate Size?
Gate size generally refers to the width of the gate leaf itself, from the outside edge of one side of the gate frame to the outside edge of the other side. For a double swing gate, this means you’d measure the width of one leaf and then multiply by two (or measure both leaves together, depending on the design).
Regarding gate height, gate size is often 2 inches (about 50mm) shorter than the overall height you plan for, primarily to allow ground clearance. In many residential settings, gates might stand anywhere between 3 and 6 feet high, while commercial or industrial gates can be taller. Variations in ground slope or unique design requirements can also affect the exact dimensions, so always verify with your fence or gate installer.
What Is Gate Opening Size?
Gate opening size refers to the measurement taken from the inside edge of one gate post to the inside edge of the other. Sometimes called the “post-to-post” dimension, it doesn’t necessarily reflect the exact free clearance. Your frame and gate hardware (including hinges and latches) can occupy some of this space.
It’s smart to note any specific free clearance you need for large vehicles or equipment. If you require a certain amount of space when the gate is open, be sure to mention that to your fence or gate company as well.
Why Hinges and Latches Matter to Gate Size
When ordering a gate from a manufacturer or working with a fence contractor, the type of hinges and latches you plan to use is significant. Different hinges require specific clearances and might affect the distance between the gate posts or between the gate frame and the post.
If you know which hardware you’ll use ahead of time, it’s easier to calculate the appropriate spacing. This is especially true if you’re looking for automated gate options or specialized hardware solutions that might require more room to function smoothly.
What About Sliding, Rolling and Cantilever Gates?
Sliding, rolling, and cantilever gates are physically larger than the opening size they’re designed for. How much larger depends on the gate style and the hardware:
• Cantilever gates are typically at least 1.5 times the width of their intended opening.
• Sliding and rolling gates often extend a foot or more beyond the opening, due to the tracking system.
Despite being bigger, the opening size is still measured from the inside face of one gate post to the inside face of the other. In many Phoenix-area homes with long driveways, a sliding gate may be an appealing option for saving space.
When In Doubt, Ask the Pros!
By now, you can see there are many factors involved in figuring out the right gate measurements. If you’re uncertain whether you should consider gate size, gate opening size or how to account for gate post spacing, it’s best to speak with a fence professional. A reputable fence company or gate manufacturer can help you accurately measure for new gates and suggest the correct posts, hardware, and spacing.
These guidelines apply to virtually every type of gate, including man gates, garden gates, pedestrian gates, driveway gates, and double swing gates. Whether you’re in Phoenix, Glendale, Tempe, or anywhere else in Arizona, always make sure you measure twice and cut once!
