#### How many hinges should be used for a door?

During furniture planning the question often arises **of how many hinges are required to achieve an optimal door motion **– for the whole life of the furniture. However, this question isn’t always that easy to answer. In this blog post, we will provide you with some tips to help you plan exactly how many hinges you will need for each door.

As a rule, the **door weight** is key in determining the number of door hinges required. However, **dimensions** and **materials** of the door also have an impact on this.

In our experience, the following number of hinges has been proven and tested:

2 hinges are optimal for door weights of 4–6 kg

3 hinges are optimal for door weights of 6–12 kg

It is important to consider the weight of the door including additional weights such as handles!

The **door height** also affects the number of hinges required. For high and narrow doors, for example, it may be wise to use three hinges for extra stability, even though, with a weight of 6 kg, this is not strictly required.

In principle, doors should have a height that is greater than their width. The values mentioned above are valid for **door widths** of up to 600 mm. If doors with a width of up to 650 mm are installed, you will have to use an additional hinge.

**Where should hinges be positioned?**

In general, the further apart the hinges are positioned, the more securely the door hangs on the cabinet.

**Support for determining the door weight**

Determining the weight of the door can be challenging in certain cases. This is why we provide a front weight calculator with our product configurator and reference values in our product catalogue for various front materials and measurements (see chapter ‘Information’).

Need you assistance. I am mounting a 84″ tall by 23″ wide door that will have a piece of 1/8″ black glass glued to the face. Total weight around 150#. How many hinges will I need to carry the weight. I was thinking of 5 sets of two hinges. What do you think and do you have any suggestions.

Thanks

Dear valued customer,

we would suggest you use 12 hinges. Please keep in mind to distribute them across the height of the front evenly (not in sets of 2 hinges).

Furthermore, we’d like to point out that we have not tested this kind of application for our hinges and recommend you try it out first.

We have a project where the architect has specified cabinets with doors that end up 36″ wide x 80″ tall. We split these into pairs 18″ x 80″ with 4 hinges each (using 170 hinges, clip top) on our shop submittals. However, the architect is pushing back. I’m trying to find any info about doors wider than 24″, or something I can refer him to indicating that 24″ is considered a maximum width. Our standard is not to exceed 24″. Is there any chart or calculation that can be used for this type application?

Dear Daniel,

Blum hinges are constructed and tested for door widths of max. 600mm (equals to 23.622 inch)

In some cases it is possible to increase the door width (e.g. to 650mm = 25,59 inch) by using additional hinges.

36 inch is a very wide door application and we agree with your suggestion to divide the doors into two.

How many hinges do I need on a 19 1/2′ x 42″ door that weighs 15 pounds?

Hi John,

we recommend you to use 3 hinges for a door with the dimensions and weight you mentioned.

Kind regards

Matthias

Can we use hinges Blum 125 for door 36″x96″ with 1/4″ and aluminum frame ?

Dear Wojciech,

is it a wide or narrow aluminium frame? With narrow aluminium frames, the 125° will not work.

Furthermore, the door weight would be essential to know.

Generally, I think that for your application the 125° hinge is not the proper solution.

Kind regards

Matthias

Our cabinet doors are 2cm silestone. The dimensions of the doors are 603mm x 958mm. The approximate weight is 28.5 kg. Is there any of amount hinges that could handle this kind of door?

Hi Paul,

due to the width-to-height-ratio and the weight, our recommendation is to use 9 or better 10 hinges.

We would like to point out that the use of furniture hinges for an application like yours is critical, and might be a challenge for the producer.

Kind regards

Matthias

What type of push to open hinges needed to handle door with 300mm(height) and 680mm (width) 20mm (thickness) with right hand size opening ?

Hi Sue,

generally, all recent unsprung hinges are suitable for our handle less TIP-ON solutions – depending on the type of application.

Due to the special type of construction (e.g. door is wider than high) our customer service in Australia will get in touch with you to clarify all the details.

I would like to hang a inside corner, bifold door, using 170 degree hinges and the bi fold 60 degree hinges.

The primary swinging door will be 21″ wide x 38″ tall, the secondary will be 14″ wide x 30″ tall.

Doors are approximately 9lbs and 6lbs respectively.

My thought is to use 3 hinges on the primary door and 2 on the secondary. Is this sufficient for that wide of a bifold door situation?

Hi Shoshana,

in my opinion this would fit. But in this case plesae make a trial, because the doors are wider than 24″.

If you need some further information please contact our sales team.

Kind regards

Andrea

Hello,

I’m planning to hang cupboard doors using your concealed hinges. The doors have the dimensions 1680mm*695mm (which I realise is slightly longer than your hinges are tested with). The weight of one door is 16kg. How many hinges would you recommend?

Many thanks,

John

Dear John,

the door seems significantly wider than what we have tested (we test up to 600mm width), but the height and weight is more than fine.

As the width has an impact on the function of dampers as well as the stability of the door, I would recommend you use a minimum of 5 hinges.

Some general information on the recommended number of hinges is found here: https://publications.blum.com/2018/catalogue/en/694/

Best regards

Dear Santosh PonnU.

Our company does not produce hinges for room doors. We produce fittings for furniture. Unfortunately we are not able to help you.

If i were to make a door that is 650mm wide by 880mm in height and use the appropriate amount of hinges is there a void in warranty on the hinges ?

Also is there any problem in make a door 650mm in width at all ? Again using the appropriate amount of hinges.

Thanks

Nathan

Hi Nathan.

Our guarantee bonds refer to doors with a maximal norm width of 600 mm. If this norm width is exceeded, there will be problems with:

– stability

– locking pressure

– lifetime

Therefore we offer our hinges only till a norm width of 600 mm.

Kind regards Andrea

Hi all,

I noticed that some companies manage to for a single door (76.5cm * 57cm )above the ovens w three hinges. 2 on top and one at the bottom. I don’t know if those are Blum but will Blum work with that size? Or do you have any other brand that might?

Hi Valentino,

we think that these dimensions (76.5cm height, 57cm width) will not cause any issues, and we’d be happy if you use our hinges for your cabinet.

In addition, if the door is lighter than 6kg, two hinges would be sufficient as well.

Please let us know if you have any other questions.

Greetings from Blum Austria

Matthias

Hi Mattias,

Thanks for the reply. Its actually 765mm Width * 570m m Height, will it work?

Hi Valentino,

we would recommend you use the hinges as you have suggested. 2 on the top, 1 on the bottom. Still, we recommend you try it out first to find out if the front will still not sag too much on the opposite side of the hinges.

Kind regards

Matthias

Hello,

How many hinges do you recommend for doors

106” x 32” weighing 63 pounds

And how many for doors

106” x 16” weighing 25 pounds?

Thank you,

Joncy

Dear Joncy,

the smaller door will most probably work with 3 hinges. But as it is a very high door we would suggest you use another 2 hinges for a better stabilisation.

The wide door is very critical due to its width of more than 800mm. Our hinges are not built and tested for such door dimensions.

You can try using a minimum of 8 hinges or more, but we can not guarantee that it will work and that the gap design can be adusted properly.

Kind regards

Matthias

Hello,

How ma any hunges would you recommend for a 18mm door that is 600 Wide x 400 High. I have heard that their are warranty issues from Blum around doors that are wider than they are higher, are you able to please elaborate?

Hi Jonathan,

basically, a door should be taller than it is wide. For a door as indicated below, the load or stress on the hinges is unfavorable. In cases of the “misuse”, (i.e. slamming a door, hanging on the door) this is critical for the integrity of the door.

For such fronts we recommend:

– Lift systems in the wall unit

– Drawers / High fronted pull-outs in the base cabinet

If you decide to use the door as you described anyway; we recommend that you install the hinges as far apart from each other on the front as possible. (One far up on the top and the other as far below on the bottom as possible) This will help increase stability.

You can also install an additional hinge in the upper area of the door to improve the situation.

But we would not be able to provide a guarantee for this installation.

Kind regards

Andrea

Hello,

Putting up some cabinet doors in a closet that are approx. 45cm wide and 282cm tall. The door, which receives mirror, is approx. 27.3 kg (with weight of mirror included). We’re going with the 110 hinges and wanted to know what you think may be a good amount. Also, we thought that knuckling hinges (having one right on top of the other) gave it extra strength. Would you not recommend that? Any help would be greatly appreciated. Thanks.

Dear Matt,

we have not tested the door weight to this extent, but we think 6 or 7 hinges should be enough. If you want to be on the safe side, place two hinges almost on top of each other (as you mentioned) at the top of the door to avoid excessive sagging of the front. As the application with this weight and door dimension has not been tested by us, we point out that we recommend you to test it before applying it with a project for a customer.

If you have any questions, our local customer service (www.blum.com/contact) will be happy to assist you.

Kind regards from Austria

Hello, I have a closet that needs 555 x 2220 mm doors. I am ordering louvre style wood doors, so my guess is that they should be lighter than the typical doors of this size.

I can have one hinge at the very bottom, but the next hinge has to go above 800mm because the drawers will be in the way. Can I get away with using 4 hinges per door? How should I mount them keeping in mind my 800mm height drawer block?

Also I need the doors to not block the drawer front faces when open, in other words the doors need to be in line (or event offset further) with the sides. A person familiar with your production said that 155 degree hinge should do just that.

Dear Rytis,

as we don’t know the exact weight of the door it is impossible to give an accurate recommendation. If the door weight does not exceed 17kg, four hinges shlould work.

Basically, please consider the following:

The two hinges on the very top and very bottom of the cabinet should be apart from each other by the maximum possible. All other hinges should be allocated symmetrically on the door. I totally see that you have drawers underneath and so can not go along this recommendation. According to our experience, it should work fine, but in such exceptional cases it is a bit difficult for us to give a reliable recommendation.

Our 155° hinge would be perfect for this solution. They are zero-protrusion, which means that when opened the door will not have any overlay on the cabinet inside and as a consequence will not collide with your drawer fronts.

Best regards and happy new year

Matthias

Hi there,

The other measures 33 3/4 x 42 1/4 with a weight of 30 lbs.

Thanks in advance
