How Wide is a Side Gate for Bins, Bikes and Garden Equipment?
Key Takeaways: A side gate around 750–900 mm can suit bin access, 900–1,000 mm provides better clearance for bikes and wheelbarrows, and 1,000–1,200 mm can provide greater flexibility for lawn mowers and garden equipment.
A side gate may look like a simple part of the fence, but choosing the wrong width can quickly become frustrating, as it affects how you move wheelie bins, bicycles, a wheelbarrow or lawn equipment into the backyard.
How wide is a side gate? This side gate width guide explains the practical clearances to consider for common household items and why the finished usable opening matters more than the nominal size of the gate itself.
How Wide is a Side Gate Be for Bins, Bikes, Wheelbarrows and Garden Equipment?
There is no single ideal width for every side gate. The right size depends on whether the gate provides pedestrian access only or needs to accommodate bins, bicycles, gardening tools and larger equipment.
As a general design starting point, the following clear openings can help homeowners compare their options.
What Needs to Pass Through | Approximate Practical Clear Opening to Consider | Main Reason |
Pedestrian access only | 800–900 mm | Comfortable everyday walking access |
120–240 L wheelie bins | 750–900 mm | Provides clearance around wheels and handles |
Standard bicycles | 900–1,000 mm | Reduces the need to carefully angle handlebars |
Mountain bikes / wider handlebars | 1,000 mm+ | Some modern handlebars are close to 800 mm wide |
Wheelbarrows | 900–1,000 mm | Provides room for tray, handles and operator |
Lawn mowers / garden equipment | 1,000–1,200 mm | Allows greater equipment flexibility |
Frequent equipment access | 1,200 mm+ or double gate | Makes bulky and future equipment easier to accommodate |
These figures are practical design recommendations rather than universal statutory minimums. Always measure the actual equipment you intend to move through the opening before the gate is manufactured.
What Side Gate Width Works Best for Wheelie Bins?
Wheelie bins are often the first item homeowners should measure because they pass through the side gate every week.
As an example, SULO lists its Australian 240-litre mobile garbage bin at approximately 585 mm wide, with a total depth of around 730 mm and total height of about 1,060 mm.
That does not mean a 600 or 650 mm clear opening is a practical choice. A bin may technically fit through that gap, but everyday use becomes much easier when you allow space for the wheels to move slightly sideways, irregular paving, your hands around the handles and the angle at which the bin approaches the opening.
A gate that does not open completely flat may further reduce the available passage.
For normal residential bin access, around 750–900 mm of actual clear opening is generally far more usable. Where several bins are stored behind the house and moved frequently, aiming towards the wider end of that range can reduce awkward manoeuvring.
How Wide Should a Side Gate Be for a Bicycle?
With bicycles, the frame usually is not the widest part. The handlebars determine whether the bike can comfortably pass through the opening. Modern mountain-bike handlebars commonly range from approximately 720 to 800 mm wide, depending on the type of bike and riding setup.
A narrow pedestrian gate may therefore allow the bike through only when the front wheel or handlebars are turned carefully.
For regular bicycle access, around 900 mm of clear opening can work for many everyday bikes, while 1,000 mm or more provides much more comfortable access, particularly for mountain bikes with wider handlebars.
Extra clearance can also be useful when a bicycle has panniers, baskets or other accessories attached. Families may also need enough room to push a child's bike through alongside an adult bike.
What Side Gate Width Is Practical for a Wheelbarrow?
Wheelbarrows create a slightly different challenge because both the equipment and the person operating it need room to move. Before selecting the opening, measure the widest part of the tray, the outside width of the handles and the position of your hands while pushing. You should also consider whether the wheelbarrow needs to turn immediately after passing through the gate.
For frequent residential use, approximately 900–1,000 mm of clear opening is a practical range to consider. If you regularly undertake landscaping or garden maintenance, additional width may be worthwhile. The same access will often be used for bags of soil, mulch, plants, timber, garden waste and other bulky materials.
How Wide Should a Gate Be for Lawn Mowers and Garden Equipment?
Garden equipment varies far more in size than bins or bicycles, so there is no useful single dimension that applies to every property.
Your side access may need to accommodate a push mower today but could later be used for a larger mower, pressure cleaner, garden cart, fertiliser spreader, green-waste bin or compact landscaping equipment.
The better approach is to identify the widest machine that is reasonably likely to use the side access and measure it at its widest point, including handles, wheels and attachments. Then add comfortable manoeuvring space rather than making the opening almost exactly the same width as the equipment.
For general residential garden access, approximately 1,000–1,200 mm of clear opening provides significantly more flexibility than a narrow pedestrian gate.
When Is a 1,200 mm or Wider Side Gate Worth Considering?
A wider opening can make sense if you regularly move bulky equipment or want the side passage to remain useful as the property changes. Consider approximately 1,200 mm or more where you:
Maintain a large garden or landscaped backyard.
Regularly move lawn equipment, soil or garden materials.
Store bicycles behind the house.
Have a pool requiring ongoing maintenance access.
Expect landscapers or other contractors to enter through the side.
Want room for larger equipment in the future.
However, making a gate wider is not automatically better. A very wide single swing gate becomes heavier. That extra weight increases the loads placed on the frame, hinges and supporting post, particularly when the gate is exposed to wind.
For occasional wide access, a double-leaf gate can be a better solution. One smaller leaf operates as the normal pedestrian entrance, while both leaves can be opened when a mower, wheelbarrow or bulky equipment needs to pass through.
Measure the Clear Opening - Not Just the Gate Leaf
One of the easiest mistakes to make when ordering a side gate is focusing on the manufactured gate dimension rather than the passage that remains after installation. A quoted “900 mm gate”, for example, does not automatically mean you will have a full 900 mm space available to walk or move equipment through.
Measure the Narrowest Point Along the Entire Side Access
Start at the front of the property and follow the complete route that bins and equipment will take to the backyard. Check for restrictions created by:
Air-conditioning condensers.
Hot-water units.
Gas meters.
Downpipes.
Steps and retaining walls.
Garden beds.
Fence posts.
Eaves or other overhead obstacles.
The narrowest point may be several metres beyond the gate. Installing a much wider gate does not solve the access problem if everything still needs to squeeze through a restricted passage beside the house.
Add Working Clearance Around the Largest Item
A simple way to determine your target opening is:
Equipment width + comfortable manoeuvring clearance = target clear gate opening.
Avoid designing the gate with only 10 or 20 mm remaining on each side. That may be enough for the equipment to technically fit, but it leaves almost no tolerance for approaching the opening on an angle, rough paving, protruding handles or normal movement while pushing the item.
When applying this side gate width guide, treat the recommended dimensions as comfortable starting points and then adjust them around your actual site and equipment.
Consider How the Gate Opens as Well as How Wide It Is
Gate configuration affects how much of the opening can actually be used. Before deciding on the width, think about where the gate leaf will sit when open and whether it interferes with the item travelling through. Common configurations include:
Inward swing: Often practical where the gate should not swing towards a public footpath. Make sure bins or equipment will not prevent the leaf from opening fully.
Outward swing: Can preserve space inside a narrow passage, but requires careful consideration beside footpaths, driveways and shared access areas.
180-degree opening: Particularly useful where the gate can sit flat against the fence instead of projecting into the side passage.
Double gates: Allow a narrower everyday pedestrian leaf while providing occasional wide equipment access.
Sliding side gates: Can work where there is enough fence length for the panel to slide but insufficient space for a swing arc.
Self-closing or lockable gates: May be appropriate where security, children, pets or pool-related requirements influence the design.
The best width can therefore change depending on the gate configuration. A slightly smaller gate that opens fully against the fence may provide better practical access than a larger leaf that remains partly across the path.
Do Accessibility or Planning Requirements Affect Side Gate Width?
An ordinary private backyard gate should not automatically be treated as having one universal accessibility-width requirement. Requirements depend on what the accessway serves and the type of development involved.
However, compliance becomes much more important where the side path forms part of a required accessible route or provides access to another dwelling.
AS 1428.1:2021 addresses matters including continuous accessible paths of travel, circulation spaces, doorways, clear openings and controls for building work where the standard applies.
Victorian planning provisions also demonstrate why unobstructed width needs to be assessed according to the purpose of the path. For example, current guidance for certain small second dwellings requires a clear path from the frontage of at least 1 metre wide, increasing to at least 1.8 metres where the path exceeds 30 metres.
That does not mean every residential side gate must be one metre wide.
Instead, determine whether the side path is simply being used for bins and gardening or forms part of a required route to another dwelling or entrance. Where compliance is involved, check the relevant planning approval, building documentation, NCC provisions and applicable accessibility requirements before fabrication.
The gate swing should also be considered so the open leaf does not obstruct required circulation space.

Frequently Asked Questions
What is a standard side gate width?
There is no single standard width that suits every home. Around 800–900 mm of clear opening can work well for basic pedestrian access, while approximately 900–1,200 mm provides more flexibility for bins, bicycles and garden equipment.
Will a 900 mm side gate fit a wheelie bin?
Generally, yes, provided the 900 mm measurement refers to the usable clear opening rather than the overall gate leaf. For comparison, SULO's Australian 240-litre bin is approximately 585 mm wide, so a 900 mm clear opening provides useful additional manoeuvring space.
Is a 900 mm gate wide enough for a bike?
It can be suitable for many bicycles, but it may feel tight with wider mountain-bike handlebars. Modern MTB handlebars commonly range from about 720 to 800 mm, so approximately 1,000 mm of clear opening can make frequent bicycle access noticeably easier.
Should I install a 1,200 mm side gate?
A 1,200 mm opening can be worthwhile if you regularly move mowers, wheelbarrows, bicycles or bulky garden equipment into the backyard. For occasional extra-wide access, however, consider whether a double gate would provide greater flexibility without requiring one large, heavy gate leaf.
Does gate width mean the same as clear opening width?
No. The gate leaf itself and the usable passage are different measurements. Posts, hinges, gate stops, latches and the angle at which the gate opens can all reduce the available space. When requesting a quote, ask the installer to confirm the finished clear opening, not only the manufactured gate size.
