A side gate should swing in whichever direction has clear space and no obstacles in its path. As a default, most side gates open inward, into the property, because that keeps the gate off the footpath and away from passers-by. But the right answer depends on what is actually in the way, the slope of the ground, and whether you have room to swing at all. If neither direction is clear, a sliding gate solves it.
Here is how to work out the right direction for your gate.
The default: swing inward, into the property
Opening inward is the usual choice for a side gate, for two reasons. It keeps the gate from swinging out over a footpath or shared path where it could clip someone walking past, and it sits the open gate inside your boundary rather than out in public space. For a standard side access with clear ground behind it, swing it inward and you are done.
That only works if the ground inside the gate is clear through the gate’s whole arc. This is where most people get caught.
What blocks an inward swing
Before you commit to inward, walk the arc the gate will travel and look for anything in the way:
- A downpipe running down the wall beside the opening.
- An electrical box or meter box mounted at gate height.
- An air-conditioning unit or hot water system.
- A garden bed, retaining wall, or step.
- A slope that rises behind the gate, which the bottom of the gate will catch and drag on as it opens.
Any one of these and the gate cannot open inward fully, so you either move the obstacle or swing the gate the other way.
Can a side gate swing outwards?
Yes. There is nothing wrong with an outward-swinging side gate, and often it is the only practical option when the inside is blocked or the ground slopes up behind the opening. Outward swing is common on sloped blocks for exactly that reason.
The thing to check is the outside. Make sure the gate will not swing across a footpath, a driveway, or your neighbour’s land, and that it will not clip anyone walking past as it opens. If the gate opens straight onto a public path, outward swing is the wrong choice and you are better off sliding it.
Which side should the hinges go on?
Once you have the direction, the hinge side comes down to convenience and the wall. Hang the gate so it opens toward the more open space, and where possible hinge it off the stronger fixing point, a brick wall or a properly footed post rather than a light fence post. A gate is only as solid as what it hangs off, so the hinge side matters as much as the swing direction. The hinges should also be fitted so the gate cannot be lifted off them, which is both a security and a long-term maintenance point.
When a sliding side gate is the better answer
If neither direction has clear room to swing, a sliding gate is the fix. It needs no swing arc at all, just clear run-back space alongside the opening for the gate to slide into. There is more on the pros and cons of sliding gates here. Sliding suits:
- Tight side access where a swinging gate would hit the house or the fence.
- A gate opening straight onto a footpath, where outward swing is unsafe and inward is blocked.
- Sloped ground where a swing gate would drag.
The trade-off is that you need the clear length beside the opening for the gate to run into, so it is not right for every spot.
Get the direction sorted before the gate is built
Swing direction is not something to leave until install day, because it changes the hinge placement, the latch side, and sometimes the whole gate type. When we measure a side gate on site, we check the swing arc both ways, the obstacles, and the fall of the ground, so the gate is built to open the right way for your space the first time. If you are also working out the right size, our guide on how wide a side gate should be covers measuring and clearances.
