Door Stops Explained: Types, Sizes and How to Choose the Right One

A door that swings too far isn't just annoying — it puts a lever handle through plasterboard, chips paint off a skirting board, or lets a knob dent a wall over and over until there's a permanent mark. A well-chosen door stop is cheap insurance against all of that, but the range of types and sizes on the market makes it easy to buy the wrong one. Here's how to work out which style you actually need, and how to size it correctly before you order.

The Main Types of Door Stops

Floor-mounted door stops are the most common option for internal doors. A short post (typically 25–50mm high) screws directly into the floor and stops the door or its handle before it reaches the wall. They work well on doors that open onto open floor space, but they're a trip hazard in high-traffic hallways and awkward on unsealed timber or tiled floors where you don't want to drill.

Wall or skirting-mounted door stops fix to the skirting board or wall at the point of impact, usually 100–150mm up from the floor, roughly in line with where a door handle or the door's edge would otherwise strike. They keep the floor clear and suit hallways, but only work if the door opens against a wall close enough to reach — measure the swing before assuming this style will fit.

Hinge-pin door stops replace or clip onto the existing hinge pin, so there's no drilling into floor or wall at all. They're the best option for doors that open onto open space with nothing nearby to mount a wall stop against, and for rentals or heritage floors where you can't drill. They do add a small amount of visible hardware at the hinge, which some buyers prefer to avoid on a feature door.

Door-mounted (or "hook") stops fix to the bottom of the door itself and flip down to grip the floor. They're rarely used in new residential fitouts but are worth knowing for doors that need to be held open rather than just stopped — a laundry or robe door, for example.

Sizing: Projection, Height and Door Weight

The number that matters most is projection — how far the stop's buffer sits proud of the floor or wall. Too short and the door handle or door edge will still clip the wall before it touches the stop; too tall and it becomes a hazard or looks clumsy. As a rule of thumb, a floor-mounted stop needs enough projection to intercept the door edge or handle before either reaches the wall, which usually means checking the distance from the hinge line to where the door will rest fully open, not just guessing from the doorway.

Heavier doors — solid timber entry doors, or anything over about 40kg — need a stop with a solid fixing point and enough mass in the base that repeated impact doesn't work it loose over time. A lightweight stop on a heavy door will eventually pull its screws or crack a tile.

Matching Finish to the Rest of Your Door Hardware

A door stop is one of the few hardware pieces that sits at floor or skirting height, low enough to be noticed if it clashes with the levers, knobs and hinges above it. If your doors are fitted in Brushed Brass or Aged Brass, matching the stop in the same finish keeps the room reading as one considered scheme rather than a mix of metals. The same goes for Nickel, Polished Nickel and Aged Nickel — each reads quite differently in a hallway, so it's worth checking a stop against your actual lever or knob finish rather than a photo, since brass and nickel tones can look closer on screen than they do in person. For a black-hardware scheme, a matching black stop is far less noticeable underfoot than a bright metal one against dark skirting.

Where You Actually Need One

Not every door needs a stop. Doors with a soft-close or damped hinge, or ones fitted with a friction stay, rarely need a separate stop. But it's worth fitting one on: any door that opens toward a wall with nothing else in the way; bathroom and ensuite doors, where a handle regularly meets tiled walls; entry doors, which take the most force and the most repeated use; and any door near glass, joinery or a light switch that a swinging handle could damage.

Buying Checklist

• Measure the door's full swing arc, not just the gap when it's ajar, to find where it needs to be stopped.
• Check your floor or wall material — tile, stone and engineered timber all take screws differently, and some floor stops suit surface-fixing better than others.
• Confirm projection height against your skirting profile if you're going wall-mounted.
• Match the finish to your existing levers, knobs or hinges rather than choosing it in isolation.
• For heavy or high-use doors, prioritise a solid fixing base over a decorative one.

Getting the type and size right at the ordering stage means the stop disappears into the room instead of becoming the thing you notice every time the door swings.
