Driveway Gate Types: Swing, Sliding, Single and Dual, Explained

There are only a few kinds of driveway gate, and your driveway usually picks one before you do. Swing or slide, one panel or two: these choices come from slope, swing room and opening width, and they shape the posts, the opener and most of the cost.

Start with the driveway, not the style

Most people start with the look and then find out the driveway has already decided. That is why our driveway gate buying guide puts swing or slide first among its eight decisions, ahead of size, material, style, posts, opener and installation. Style comes late because it barely changes the price of a steel gate, while the gate type changes the hardware, the site work and the opener.

Three things on your driveway settle the type:

• Room to swing. A swing panel needs clear space on one side of the opening, about the width of the gate, free of parked cars, the garage door path and landscaping.
• Slope. A panel that swings into rising ground hits it before it is fully open.
• Width. Hinge load grows fast with width, so wide openings favor two panels or a slider.

Swing, sliding and cantilever compared

The swing vs. sliding guide walks through five site checks: room to swing, slope, opening width, what the opener has to do, and where cars stop. Here is how the three motions line up.

Cost follows the same order. Plan on roughly 25 to 30 percent more for a slider than for a swing gate of the same width and material, and another 15 to 20 percent for a cantilever over a tracked slider. Where cars stop matters too. With a swing gate that opens outward, a visitor on a short apron may have to wait in the street, while a slider has no arc at all.

A fourth type, the bi-fold gate, folds back on itself for openings with no room to swing or slide. It is a specialist choice, uncommon on homes, and it needs flat ground.

Single or dual swing

Once you know the gate swings, the next question is one panel or two. The single vs. dual swing guide treats each panel as a lever: its whole weight hangs on one post, and the longer the panel, the harder it twists that post.

• Up to about 12 feet: a single panel is simple and cheaper to hang and automate.
• 12 to 16 feet: either works. A single panel this wide needs a heavy-duty 3/16-inch wall hinge post and a deep footing; two panels halve the lever.
• 16 to 20 feet: two panels, nearly always.
• Over 20 feet: consider a slider.

Swing room often settles it. Each panel sweeps a quarter circle as wide as the panel, so a 14-foot single needs 14 feet of clear driveway, while two 7-foot panels need 7 feet each. Two panels also give you a walk-through: open one by hand on foot and both for the car. The trade-off is automation, since a dual gate needs two openers sold as a pair, which costs close to double.

When the ground is not flat

Slope is the check that rules out swing gates most often. A gate that swings uphill hits the ground. A gate that swings outward over the sidewalk is not allowed in most places. A cross-slope leaves each side needing a different ground gap. A tracked slider handles a gentle cross-slope, and a cantilever handles any slope because nothing touches the ground. Two shorter swing panels rise less across their arc, which sometimes lets a dual swing work on a gentle cross-slope where a single would not.

Learn the words before the quotes

Quotes and opener boxes use trade terms like clear opening, apron, run-off, hinge post, drop rod, duty cycle and UL 325. The driveway gate glossary defines each one in plain English, in the order you meet them. A few matter when you choose a type:

Clear opening

Inside face of one post to inside face of the other. The gate is built narrower to leave room for hinges and the latch.

Apron

The stretch of driveway between the street and the gate. A short apron favors sliders and dual swings.

Run-off

The straight length of fence line a sliding gate travels along when open.

Drop rod

A rod on a dual gate's fixed panel that drops into a sleeve in the driveway to hold it shut.

One gate, built either way

We build one gate, in welded 2-inch steel tube, and the same gate can be built to swing or slide, as one panel or two. In the configurator you switch the motion or the panel layout and the price updates for your exact width. Run the site checks, pick the type, then spend your attention on the fun part: pickets, arch or finials, ironwood and color.
