Single Vs Double Driveway Gates – Which Should You Choose?

For driveways under 3.5 metres wide, choose a single gate. For driveways 3.5 metres and wider, a double gate will look more proportionate and give you easier vehicle access. If you’re parking a caravan, trailer, or two cars side by side, double is the practical choice regardless of width.

Still not sure which fits your property? This guide covers the five factors for choosing single or double driveway gate, that are width, vehicle access, cost, home style, and driveway slope.

What’s The Difference Between A Single And Double Driveway Gate?

A single gate is one panel that is hinged on one side or sliding across the opening on a track. A double gate is two panels that either meet in the middle (swing style) or one wider panel on a heavier sliding system.

Both configurations can be automated. Both come in aluminium, steel, and wrought iron. The difference is width, proportion, and how you use your driveway day to day.

Driveway Width: The Most Practical Factor

Measure your driveway opening before you decide anything else. This single measurement will point you toward the right configuration more reliably than any other factor.

Driveway width	Recommended config	Why
Under 2.5m	Single	Double gate panels would be too narrow to look balanced. Single is the only practical option.
2.5m – 3.4m	Single	Most cars fit through comfortably. Single gate is simpler, lower cost, and proportionate.
3.5m – 4.5m	Either	Both work. Double suits wider, symmetrical facades. Single suits minimalist or modern homes.
4.5m and over	Double	A single gate panel this wide becomes heavy, slow to open, and awkward-looking on the property.

A single gate on a 4.5 metre opening looks awkward, it sits off-centre and leaves the property looking unfinished. A double gate on a 2.5 metre driveway creates a tight clearance that’s frustrating to drive through daily. Width is the starting point, not a suggestion.

How Many Vehicles Need to Fit Through and What Type?

A single gate on a 3m driveway will fit most standard passenger cars without issue. Where things get tighter is when you factor in what you’re actually driving and parking.

Choose a double gate if you:

Park a 4WD, ute, or van wider than 2 metres
Own a caravan, boat trailer, or horse float
Need two cars to pass through close together
Have a side-by-side double garage at the end of the driveway

A single gate works well if you:

Drive a standard sedan or small SUV
Have a single-car garage or one regular parking space
Want a simpler, lower-maintenance setup

Daily frustration is a real cost. A gate that forces you to inch through at an angle every morning is not a gate that’s working for you.

Cost Comparison: Single vs Double

Double gates cost more than single gates, but how much more depends on the style and automation type.

Single gate: Less material, one motor (for automated swing), lighter hardware overall. Generally the more affordable entry point for driveway gate automation.
Double swing gate: Two leaves, two motors, centre-meet locking hardware, and two sets of hinges. More swing gate components means higher supply and installation cost.
Double sliding gate: One motor, but a heavier panel and a longer track system. The sliding gate motor works harder and the track requires a longer clear run alongside the driveway.

As a rough guide, a double gate typically costs 30–60% more than a comparable single gate installation, depending on material and motor choice. For an accurate figure specific to your property, a free measure and quote will give you real numbers rather than estimates.

Which Looks Better on Your Property?

In gate design, proportion is key. Even if the gate is well made, it will look out of place if it doesn’t fit the opening.

Single gates suit:

Narrow inner-suburb blocks and terrace frontages
Cottages and period homes with tight entrances
Modern minimalist homes where a single clean line reads better than symmetry
Properties where the garage is off to one side

Double gates suit:

Wide suburban driveways with centred entrances
Federation, colonial, and Californian bungalow homes where symmetry is part of the architecture
Contemporary homes with large, statement facades
Properties where the gate is the main design feature of the frontage

A useful test: stand at the street and look at the full width of your property frontage. If the driveway takes up more than a third of that width, a double gate will look proportionate. If it’s a narrow cut in a longer fence line, a single gate will read as the right scale.

What About the Gate Style and Material?

The single vs double decision doesn’t limit your material or design choices. Both configurations are available in:

Aluminium – lightweight, rust-proof, low maintenance, suits modern and contemporary homes
Steel – strong and heavy, suits larger properties and commercial-style aesthetics
Wrought iron – traditional and ornate, suits Federation, Victorian, and period homes

The configuration affects the hardware and motor setup. The material and style are a separate decision made after you’ve settled on single or double.

Driveway Slope Another Deciding Factor

Before you make a choice, it’s good to know that slope affects gate type more than gate configuration. A sloped driveway rules out ground-mounted sliding gates (the gate would need to be lifted or the track would require major groundwork). Swing gates and cantilever sliding gates handle slopes better.

If your driveway runs downhill from the street, mention it when you request a quote. It changes which types of gates will work for your opening, whether you want a single or double gate.

Quick Decision Checklist

Run through these five questions and your answer will be clear in most cases:

Question	Points to single	Points to double
How wide is your driveway?	Under 3.5m	3.5m or wider
What vehicles use it daily?	Standard cars	Large 4WD, caravan, trailer
Do two cars ever need to pass?	No	Yes
What is your home’s frontage like?	Narrow or asymmetric	Wide or symmetrical
What is your budget priority?	Keep cost lower	Invest in kerb appeal

So Which One Should You Choose

Single gates are the right choice for narrow driveways, tight budgets, and properties where a single panel fits the scale of the frontage. Double gates are the right choice for wide driveways, larger vehicles, and homes where proportion and kerb appeal matter.

Neither is universally better. The right gate is the one that fits your driveway, suits your vehicles, and looks like it belongs on your property.

Not Sure Which Configuration Suits Your Driveway?
