How Wide Should Your Backyard Gate Be?

A backyard or side gate may appear to be a minor detail when designing a home. It is often selected after the house position, fencing, landscaping and external services have already been decided.

However, the width of this gate can determine whether large appliances, furniture, garden equipment and building materials can reach the backyard or enter the home without part of the fence being dismantled.

A narrow gate may be adequate for everyday pedestrian access. The problem often becomes apparent only when a large refrigerator is delivered, an outdoor setting needs to be moved, landscaping work begins or renovation materials must be brought to the rear of the property.

By that stage, increasing the opening may be considerably more difficult than allowing a little extra width during the original design.

A large refrigerator can expose the problem

Modern French-door and side-by-side refrigerators can be much larger than people expect.

Many current large-capacity models are approximately 912–915 mm wide. Packaging can increase the overall width to approximately 972 mm, while the appliance may also be heavy, deep and difficult to manoeuvre.

A refrigerator can sometimes be turned sideways because its depth is less than its full front width. Delivery workers may also remove the packaging, handles or refrigerator doors where the manufacturer’s instructions permit it.

However, this does not mean that every refrigerator will pass safely through a narrow gate.

There must be sufficient space to:

• bring the appliance through the opening on a trolley
• protect the refrigerator and surrounding surfaces
• turn the appliance before and after the gate
• pass fence posts, hinges and latch hardware
• move around downpipes, air-conditioning units and other services
• negotiate steps, slopes and uneven ground
• align the appliance with the patio or external doorway

A wide rear sliding door may provide a much better entry point than the front door. However, that advantage is lost if the refrigerator cannot first pass through the side gate and along the side of the house.

The result may be a cancelled delivery, additional delivery charges or the need to remove a fence panel and post simply to bring the appliance inside.

Measure the clear opening, not the gate itself

One of the most common mistakes is to assume that a gate described as 900 mm or 1,000 mm wide provides the same amount of usable access.

The important measurement is the finished clear opening when the gate is fully open.

The actual opening may be reduced by:

• gate posts
• hinges
• latch mechanisms
• stops and brackets
• the thickness of the gate
• the direction in which the gate swings
• a gate that cannot open fully because it hits the house, fence, garden bed or another obstruction

A nominally wide gate can therefore provide a noticeably narrower passage.

When discussing the gate with a builder or fencing contractor, ask for the intended clear opening between all fixed obstructions. This measurement should reflect the completed installation rather than only the nominal size of the gate leaf.

How wide should a side gate be?

There is no single width that suits every property. The appropriate opening depends on the available side setback, the intended use of the backyard and the types of items that may need to pass through it.

As a practical design guide:

• an opening below approximately 900 mm may be suitable for pedestrian access but can be restrictive for large items
• a true clear opening of approximately 1,000 mm provides more useful everyday access
• an opening of approximately 1,200 mm is considerably more practical and future-proof where the site allows it
• a 1,500 mm opening, double gate or removable secondary section may be preferable where access is required for landscaping equipment, bulky furniture or substantial renovation work

These are practical planning dimensions rather than universal regulatory requirements. The correct width should be selected for the particular home, site and access route.

Australian suppliers offer standard, adjustable and custom garden gates across a broad range of widths, including products extending to approximately 1,200–1,500 mm. This means that a narrow pedestrian gate is not the only available option where the site has sufficient space.

For many family homes, approximately 1,200 mm of genuine clear access provides a useful balance. It remains convenient for normal pedestrian use while making it substantially easier to move large appliances, bins, barbecues and garden equipment.

The entire access route must be checked

A wide gate alone does not guarantee practical access.

The complete route should be considered from the driveway or street to the final destination. The usable access width is determined by the narrowest point anywhere along that route.

Possible restrictions include:

• a narrow space between the house and boundary fence
• an air-conditioning condenser positioned in the side passage
• a hot-water unit projecting from the external wall
• downpipes, taps, gas meters or electrical equipment
• retaining walls or raised garden beds
• steps between different ground levels
• drainage pits or grates
• an external door that provides a smaller opening than the gate
• a sharp corner immediately before the patio
• insufficient room to rotate a large item

The route should also have a reasonably firm and level surface. Moving a heavy refrigerator or outdoor appliance over soft soil, loose gravel, deep mulch or stepping stones can be unsafe and may damage the item.

A continuous paved or concreted access path can be just as important as the gate width.

It is not only about refrigerators

A wide side gate may be used only occasionally, but when it is needed, it can prevent substantial inconvenience.

Items that may need to pass through the backyard gate include:

• outdoor dining tables and lounges
• large barbecues and outdoor kitchens
• lawnmowers and garden machinery
• wheelbarrows and green waste
• ladders and scaffolding components
• building materials for future renovations
• replacement air-conditioning equipment
• pool and spa equipment
• cubby houses and trampoline components
• water tanks and pumps
• soil, mulch and landscaping supplies
• construction waste being removed from the backyard

Without suitable side access, these items may need to be carried through the garage, hallway or living area. This increases the risk of damaging walls, floors, doors and furniture.

In some homes, there may be no practical internal route at all.

Planning the gate during a new build

The best time to consider side access is before the house and external services are positioned.

A gate should not simply be fitted into whatever space remains after construction. The access route should be coordinated with the site plan, house footprint, fencing and landscaping.

During the design stage, consider:

• the intended finished clear opening
• the distance between the house and boundary
• the position of fence posts
• the direction in which the gate will swing
• whether the gate can open fully against the fence
• the location of air-conditioning units and hot-water equipment
• the position of downpipes, taps, meters and drainage
• the width and surface of the side path
• any steps or changes in level
• the width of the patio or rear external door
• the route from that door to the kitchen and refrigerator recess

The refrigerator recess may be designed for a large appliance, but that is not sufficient by itself. The appliance must also be able to reach the recess.

This is particularly important in compact homes, duplexes and dual key properties, where side setbacks and external service areas may be tightly planned.

A double gate can provide flexibility

Where sufficient width is available, a double gate can be a practical solution.

One leaf can operate as the everyday pedestrian gate, while the second leaf remains secured with a drop bolt and is opened only when wider access is required.

This arrangement can provide convenient normal access without requiring one very large and heavy gate leaf. It can also make the opening more adaptable for furniture deliveries, garden machinery and future building work.

Another option is a removable fence section or removable post designed as part of the original fencing system. This is different from unexpectedly dismantling a conventional fence. The components are deliberately configured so that wider access can be created without destroying the fence or excavating a concreted post.

Improving access at an existing home

A narrow gate can often be improved after the home has been completed, although the available options depend on the side passage, fence construction and location of services.

Possible solutions include:

• replacing the existing gate with a wider custom gate
• relocating one or both gate posts
• changing the hinge position or opening direction
• installing a double gate
• converting an adjacent fence section into a second opening leaf
• creating a properly designed removable fence panel
• adjusting landscaping that restricts the passage
• relocating minor obstructions where practical

Before moving posts or altering the fence, the contractor should check the boundary position, underground services, retaining structures and any equipment attached to or located near the fence.

Additional care is required where the gate forms part of a swimming-pool enclosure. Any alteration must preserve the required operation and safety of the barrier.

Why removing a fence section is not a good permanent solution

Removing a fence panel may sound straightforward, but it is often more complicated than expected.

Fence sheets or palings may be screwed, nailed or interlocked. Posts may be set deeply into concrete. Removing them can damage adjacent sections, landscaping or underground services.

After the delivery, the fence must be reconstructed and realigned. Older materials may be faded, weathered or no longer available, making the repaired section visibly different from the rest of the fence.

There may also be:

• labour and material costs
• delivery delays
• temporary security and privacy problems
• damage to the appliance or fence
• disturbed concrete or paving
• the need to involve a fencing contractor
• the same problem again when the appliance must eventually be replaced

A refrigerator does not remain in a home forever. Even when the existing appliance has somehow been brought inside, the access issue will return when it needs to be removed or replaced.

Planning a suitable gate is therefore a long-term decision, not merely a solution for the first delivery.

Questions to ask before finalising the gate

Before approving a gate or side-access design, confirm:

• What will the actual clear opening be when the gate is fully open?
• Can the gate open completely without hitting another structure?
• What is the narrowest point along the entire side passage?
• Is there enough room to turn a large appliance?
• Are any services likely to obstruct the route?
• Is the path firm, level and appropriately drained?
• How wide is the rear external doorway?
• Can large furniture and appliances reach their intended rooms?
• Would a double gate or removable section be more practical?
• Could future landscaping or equipment reduce the available width?

A gate should be planned according to what must pass through it, not merely according to what looks proportionate in the fence.

A small design decision with long-term consequences

Side-gate width is easy to overlook because it may have little effect on everyday life immediately after the house is completed.

However, the first large appliance delivery, landscaping project or renovation can reveal how important the access route really is.

Providing a wider gate during construction is generally simpler than modifying posts, fencing, paving and services later. For an existing home, a properly designed wider gate, double gate or removable access section can prevent the fence from needing to be dismantled each time a bulky item must reach the backyard.

How ARK Houses can help

At ARK Houses, we consider side access as part of the practical design of the entire property rather than an afterthought added after construction. When building a new house, duplex or dual key home, we can coordinate the gate opening, fence posts, external services, pathway and rear-door access so that large appliances and equipment can be moved without dismantling the fence. For an existing home, we can assess the available side passage and, where practical, install a wider gate, double gate or purpose-designed removable access section.
