There are many different types of hinges around for your gates and garage doors, and as I’m asked quite often ‘which hinge should I use?’, ‘what size do you recommend?’ etc, I thought I’d do a brief (or not so brief depending on how this turns out) guide to garage door and gate hinges.
You’re probably familiar with Tee hinges, or Cross Garnet hinges as they are sometimes known, as they are quite a common hinge. They can be found on lightweight gates, garage doors, shed doors and even internal, cottage style, ledged and braced doors.
The Tee hinge comprises a rectangular-shaped knuckle which fits to the gate post (or door frame) and has a tapered strap which fits to the gate (or door).
These are available in several gauges of light, medium and heavy duty (although we only stock the heavy duty), and a couple of different finishes: Bright Zinc Plated, Black, Premium Black (black over galvanised) and Marine Grade stainless steel.
Being a surface mounted hinge, it’s fairly easy to fit. Once you’ve got your gate or door in position, just fire the screws into place and you are done!
What size Tee hinges do I need?
As even the strongest Tee hinge is no match for the rest of the hinges mentioned below, you need to be looking at a hinge length of half the width of the door/gate you are hanging. So, on say, a gate width of 900mm, then you’ll need at least a 450mm hinge.
For any gate or door over 2100mm (approx 7ft), then a third hinge should be added; though to be honest, if you’re hanging any external gate or door this tall then you should be really looking at a stronger hinge.
The Tee hinges can be found in our gate hinges section of our shop.
These are similar to the Tee hinges, however, these feature two tapered straps. These are surface-mounted hinges and attach only with screws.
These are used on bi-folding gates and doors (i.e. when hanging a gate (or door) from another gate (or door).) as an alternative to either the band and gudgeon or adjustable hinges.
You’d hang the door or gate from the frame or gate post in the usual way using any of the hinges mentioned above, then use the strap hinges to hang the inner gates from this gate.
Limited sizes and finishes are available, and they seem to become more limited in both each year.
Band & Gudgeon hinges
Sometimes referred to as hook and pin, hook and band or hook and ride hinges, the Band and Gudgeon gate hinges are a lot more substantial than the previously mentioned Tee hinges and used everywhere from timber gates, garage doors to stable doors.
The Band and Gudgeon hinges come in two pieces; you’ve the rectangular hinge plate which attaches to the gate post, and the band which attaches to the gate. The hinge plate features a hook (or pin, hence the alternate name!) and the band sits over this hook.
The hinge plate attaches to the post with screws, whilst the band attaches to the gate with screws and one coach bolt. Although not hard to fit, they are a bit more fiddly on account of the coach bolt that goes right through the gate or door.
A common complaint on the Band and Gudgeon hinges is that there is a fair bit of play (movement) between the band and strap, and once you’ve got the gates hanging and remove the packers, it can be difficult keeping the gates at the correct height as they tend to drop slightly, meaning your nice straight and level gates are not quite so level anymore!
The downside to the Band and Gudgeon hinges is that once fitted, with a bit of effort, the gates can be lifted off the hinge pins. To overcome this, it is recommended that the top hinge pin is fitted upside down (see below for more info).
Straight or cranked Band & Gudgeon hinges?
There are two versions of the Band and Gudgeon hinges: cranked and straight.
The image shows the cranked hinge above the black straight hinge, viewed from above.
If, for example, you are fitting a pair of garage doors to a frame and you used the straight version of the Band and Gudgeon hinges, you’ll find that unless you sink the hinge plate into the door frame, the doors will stand proud of the frame by the thickness of the hinge plate.
The cranked version overcome this by having a crank (hence the name!) in the band, meaning your doors will sit flush with the door frame.
What size Band & Gudgeon hinges do I need
A rule of thumb for most gate hinges (Tee hinges excepted) is that the hinge length should be one third of the width of the gate or door it is fitted to for normal domestic use; so a 900mm (3ft wide or therabouts) wide gate would be fine with a 300mm (12″) hinge.
For heavy duty use, then it should be half the width of the gate or door, i.e. a 900mm wide gate or door means a 450mm long hinge.
For any gate or door over 2100mm (approx 7ft), then a third Band and Gudgeon hinge should be added.
Available sizes of Band and Gudgeon hinges
The Band and Gudgeon hinges come in various finishes (self colour, BZP, hot spelter galvanised, black, premium black and stainless steel) and lots of sizes (200mm, 250mm, 300mm, 350mm, 400mm, 450mm, 500mm, 600mm, 750mm, 900mm, 1050mm and 1200mm), although not all finishes are available in all sizes.
* Of the sizes listed above, we no longer sell the 200mm, 250mm and 350mm
in black or galvanised, due to lack of demand.

Adjustable Gate Hinges
These so exactly the same job as the cranked Band and Gudgeon hinges but they are adjustable as the name implies.
Quite often used with gates that are being automated using the ram type above ground systems, they are ideal for manually operated gates as well and if you’ve never attempted to hang a gate before, then these may be for you.
Like the hook and ride hinges, you’ve got a hinge plate which features a hook, a band which sits on the gate and also a long threaded bolt which has an eye on the end. The eye sits around the pin, whilst the other end of the bolt fixes through the band and the adjustment is via two nuts that tighten the bolt to the band.
Basically, once you’ve hanged your gates, you’ve got a bit of adjustment to level or shift the position of the gate; these are actually useful if, over time, your gate post sags down under the weight of the gates. If this happens, then in all likelihood, your gates will catch on the floor; with the adjustable hinges, it’s simply a case of altering the position of the gate.
The adjustment is also handy for novice gate hangers, as you don’t have to get everything bang on level first time during fitting, you can pull the gates back to level once fitted.
Like the Band and Gudgeon hinges, these attach to the gate post via screws whilst the band attaches with screws and one coach bolt.
As with the Band and Gudgeon hinges, once fitted, the gates can be lifted off the pins albeit with a bit of effort (again see below for more info).
Available adjustable gate hinge sizes
You have not got quite the same range of sizes of adjustable hinges than you have with the cranked band and gudgeons. Available sizes are 350mm, 450mm, 600mm, 750mm, 900mm and 1200mm.
Available finishes are galvanised, black, premium black and stainless steel, though not all sizes are available in all finishes.
Can I use adjustable gate hinges on garage doors?
Yes, you can use adjustable hinges on garage doors, however, you will be limited slightly on how much you can adjust the position of the doors, due to the doors (usually) being trapped/enclosed within a frame and any adjustment will in most cases be minimal.
What size adjustable hinges do I need?
As with the Band and Gudgeon hinges, normal domestic use is one third the width of each gate. For heavy duty use, then half the width of each gate.
Again, for anything over 2100mm (7ft) high, then a third adjustable hinge should be added.

Reversible hinges differ from the Band and Gudgeon hinges, as the pin is actually attached to the band. Rather than having a hinge plate, you have two hinge cups that sit above and below the hinge pin.
Again, a surface mounted hinge, the band and cups attach to the gate or door with screws and like with both the adjustable and Band and Gudgeon hinges there is a coach bolt to go through the hinge and out the other side of the gate or door.
A thing to bear in mind with the reversible hinges is that due to the size of the hinge cups, you’ll need a bit more room on your gate post or door frame to fit these.
You’ll not need a degree in hinge fitting to use these; again, they just attach onto the surface of the gates. As with all the hinges above (tee hinges excepted), you just need to drill the coach bolt hole with a bit of care.
They are a bit nicer looking (Phwoar!… if that’s your thing) than either then Band and Gudgeon or adjustable hinges and again are used on gates, stable doors, garage door etc. and due to how the cups fit the hinges, then the gates or doors cannot be lifted off.
Finish-wise, the reversible hinges are available in galvanised, black, premium black (black over galvanised).
Available reversible hinge sizes
There is not quite the size range of adjustable hinges as there are Band and Gudgeon hinges but you’ve got a choice of 250mm, 300mm, 350mm, 400mm, 450mm, 500mm, 600mm, 750mm, 900mm, 1050mm, 1200mm.
What size reversible hinges do I need?
We only use the heavy-duty reversible hinges, so again it’s one third the width or each gate or door for normal domestic use and half the width of each door or gate for heavy duty use.
Reversible gate hinges can be found here!
Again, any gate or door over 2100mm (7ft) should have a third hinge added.
Field gate hinges
As the name suggests, traditionally used on Field gates and the great thing about these is (depending on how you fit them) they can allow the gates to swing both ways!
Unlike all the other hinges mentioned above, field gate hinges wrap around the gates, which is why they are also known as wrap around hinges.
When purchasing field gate hinges in sets, you’ll find the bottom hinge is a lot shorter than the top hinge. This is due to the fact that on a field gate, the top hinge sits on the gate stile (vertical upright) and along the top rail. The bottom hinge only has the gate stile to sit on, so is shorter. So when purchasing field gate hinges in sets, bear in mind that the size given is usually the length of the top hinge.
Another thing worth mentioning on field gate hinges is that they are made for a 75mm / 3″ thick gate. This is fine for field gates for farmers as they are usually rough sawn, however, if you have a gate with a smoothed-planed finish, it will more than likely be around 70mm / 2 3/4″ thick. In these instances, your only option if you’ve got to use field gate hinges is to use a ‘hinge packer’ between the gate and hinge (on one side) to make the hinge fit snugly. A hinge packer would usually be in the same timber as your gates are made from.
Field gate hinge sets
The most common way of buying field gate hinges is in sets and you’ve a choice of three different sets. The sets being:
- Fieldgate hinge sets on 100mm (4″) square plates
- Adjustable bottom hinge field gate hinge sets on 100mm (4″) square plates
- Adjustable bottom hinge field gate hinge sets
Fieldgate hinge sets on 100mm square plates
These are similar to the Band and Gudgeon hinges in that you have the hinge that wraps around the gate and then you have a 100mm square plate with the hook or hinge pin upon it, which fixes to the gate post.
Adjustable bottom hinge field gate sets on 100mm square plates
Top hinge is the same between these and the aformentioned field gate hinge sets on square plates; however, the bottom hinge is in two pieces and clamps around the heel (bottom) of the gate stile (vertical upright).
The bottom hinge then has a bolt tightened through it which also allows adjustment of the gate, so again you can move the gate around once fitted, though only from the bottom hinge as the top hinge is fixed.
Adjustable bottom hinge field gate hinge sets
These are as above, but rather than having square plates to hang the gates from, you have a hook to drive and hook to bolt.
The hook to drive is a fearsome looking pointy thing (technical term!) that is driven into
the still beating heart of a vampire a wooden gate post after first drilling a hole through the post which is slightly narrower than the hook to drive. Hook to drive is usually used for the bottom hinge.
The hook to bolt is a long threaded bar with a hook on one end. The threaded bar goes through the post after a hole has been drilled, a bolt is then tightened to secure the hook to bolt in position.
What size field gate hinges do I need?
Traditionally, the sets come in three sizes: 600mm (24″), 450mm (18″) and 300mm (12″) with the size referring to the length of the top hinge. The bottom hinge is always 125mm (5″) long.
Again, aim for the hinge being a third of the width of each gate.
The field gate hinges and hinge sets can be found in the Field gate and equestrian section of our shop.
Fitting new hinges to existing hinge pins
If you’ve existing hinge pins that you are trying to get hinges to fit, then in most cases the pin sizes vary: as the hinges get bigger then so do the hinge pins.
Below is a list for applicable hinges and the sizes of the pins. All sizes are correct at time of writing this!
Cranked Band & Gudgeon hinges (Galv, black, black on galv, stainless steel finishes only)
300mm (12″) – 12mm (1/2″) pin
400mm (16″) – 12mm (1/2″) pin
450mm (18″) – 16mm (5/8″) pin
500mm (20″) – 16mm (5/8″) pin
600mm (24″) – 19mm (3/4″) pin
750mm (30″) – 19mm (3/4″) pin
900mm (36″) – 19mm (3/4″) pin

1200mm (48″) – 19mm (3/4″) pin
Adjustable gate hinges (Galv, black finishes only)
All 19mm pins
Adjustable hinges (black on galv only)

750mm (30″) – 19mm (3/4″) pin
900mm (36″) – 19mm (3/4″) pin
Field gate hinges
All 19mm pins
* Tee hinges, strap hinges, reversible hinges and D&D hinges are not hinges that will fit existing hinge pins.
What is to stop your gates (or doors) from being lifted off their hinges?
Both the adjustable hinges and band and gudgeon hinges can be lifted from the hinge pins if somebody is determined enough to do it. It does tend to be more of an issue on smaller pedestrian gates than larger driveway gates but fear not, you can stay one step ahead of this by simply fixing the top hinge pin upside down.
It’s not a problem on garage doors as if someone tried to lift them off when they are closed, then they are trapped by the door frame.
What’s to stop somebody unscrewing my gates or doors?
Again this can be a problem; you can get around this by substituting a couple of the screws for coach bolts (making sure the bolts tighten on the inside) or by using anti-vandal non-removable screws.
As an extra security layer on outward opening garage doors, it is recommended that you fit hinge bolts. These are protruding bolts that sit in the edge of the door (one just below the top hinge, one just above the bottom hinge) and as the doors close they locate into a receiver in the door frame.
These are very inexpensive to buy and quite simple to fit. Due to the amount of garage doors we make, I always recommend these yet few people want them!
Building hinge pins into a wall
If you intend to build hinge pins into a wall that you are constructing then you need ‘hooks to build’.
Whe using the hooks to build, they are bedded into mortar between brickwork / stonework courses. Once the mortar has dried, you can hang your gates!
There are two options available for these, for 9 inch brickwork which have a 19mm pin andfor 4 1/2″ brickwork have a 11mm pin.
If you’ve any questions or want more information then leave a comment and I’ll come back to you as soon as possible.
All sizes given above have been checked by ourselves and our suppliers and are correct at time of writing. Sizes relate to the hinges we use and supply, so if you’ve read this and got hinges elsewhere and they don’t for example fit your hinge pins they are more than likely from a different supplier.
