Questions and answers

Sliding door sizes. Everything you need to know before you buy

The variety of sliding door sizes can overwhelm - after all, how do you know at a glance whether it is better to select single or double-leaf doors? And how to properly choose the dimensions of sliding doors to avoid mistakes? At Reno, we like to talk about what we do and support our customers in their choice, which is why we have created this article, so you can take advantage of the wide range of possibilities we offer and properly integrate the door into your unique interior.

The most popular dimensions of sliding doors

Let's start with the door sizes most frequently chosen by our customers. The height is usually the standard 210 centimetres - but the width is often a problem for many. Which interiors are suitable for each size, and how can you make the best use of their unique qualities?

Standard - 90 x 210

This is one of the most common sizes that our clients buy. This is due to the specificity of modern construction - the passages between rooms are often approx. 80 cm, so installing a 90 x 210 door is an ideal solution. (Why not 80, if this is the amount of the door opening? More on that in a moment!)

They will fit great everywhere - in the bedroom, the office, the hallway. Thanks to the personalization options, you can easily choose their style to your needs. Maybe glass to let the light to the kitchen? Or maybe fully wooden to create a cosy atmosphere from the very entrance?

Tip from Reno:

If you like unusual approaches in room arrangements, remember that single-leaf doors are not the only option - double doors 45 x 210 will fit the same openings as 90 x 210, and at the same time they will diversify the composition a bit. They will also be perfect when there is no space to open a 90 cm door leaf on one side of the opening.

Think about them, for example, when you want to open up a living room, but you do not have a wide entrance to it. Symmetrical, sliding doors will add character to the interior.

Medium - 120 x 210

The slightly larger doors, which we often produce for our clients, measure 120 x 210 centimetres. What is the maximum width of the opening where they can be installed? We recommend that the door opening should not exceed 110 centimetres for the best effect.

For this size, of course, a double-leaf option is available, i.e. two times 60 cm. This choice will work best in the living room, dining room or other larger rooms - imagine an artistic studio or a library room on the first floor, where you can get into through a wooden door such as XX! A dream, isn't it?


Other - non-standard dimensions

We know that each interior has its own rules, so it would be completely unlike our way not to accept orders for doors made to size! :)

We are happy to make various non-standard widths of sliding doors for you. Where does this need come from? What projects have we done so far?

  • Narrow - we sometimes produce doors only 70 centimetres wide, which are most often used by customers in non-standard aisles. For example? For utility rooms, in older interiors, tenement houses or even as a cover for certain elements of equipment which you want to hide, e.g. uncovered stoves;
  • Wide - in large interiors, such as exceptionally spacious living rooms or dining rooms, large, double-leaf doors look fantastic, which is why we are not surprised by orders for double-leaf doors with a total width of 220 cm (110 cm x 2). Suitable for openings up to 200-210 cm wide.

The great advantage of double-leaf doors is the ability to close half or all of the door opening, which allows you to flexibly decide how open the interior will be at a given moment.

Non-standard dimensions on request

At Reno, we do not limit ourselves to standard dimensions - we will make any project for you. We are able to modify the width and adjust the height of the door to your room. If you have any questions or want to find out how much the door of your idea would cost - contact us.

How to choose the right dimensions of sliding doors?

You already know what the dimensions of sliding doors are most often chosen by our customers - but because each interior is different, learn a few basic rules, so you can match the right door size to your flat or house.

Choosing the height of the sliding door

The height is the less complicated dimension - because the door is mounted on the wall, not in within the opening, you have a wide choice, and you are literally limited by one rule: for doors with tracks, the distance between the door and the ceiling must be 15-22 cm. Also, be sure to check that you have enough space for the full length of the sliding track!

More details can be found in our Buying Guide.

Choosing the width of the sliding door

The question of the width of the sliding door is a bit more complex. The main thing is to choose a door wider than the opening where you plan to install it.

Standard single-leaf doors should be wider than the opening by a minimum of 6 centimeters (optimally by 10 cm). The margin may be larger (e.g. 20 centimeters) but not smaller (e.g. 5 centimeters).

Why does the door need to be wider than the opening?

  1. Sliding doors are mounted on tracks. The distance from the wall - depending on the model - ranges from 1,8 to 2,8 centimetres, therefore the width of the door should be selected in such a way that there is no gap between the rooms when looking at an angle.
  2. Larger doors mean more mute - if you want to, for example, separate the children's room from the living room also mute the sound, choose a slightly wider door.
  3. It is also worth mentioning the aesthetic values - large doors made of brushed wood in a spacious interior will add an extraordinary character.

An example of choosing the width of the door

Let's take a look at the most popular door openings and door widths to help you understand how door selection works. Remember - the minimum excess you need to consider is 6 centimetres.

This means that if the opening width is x cm, then the door width y will be the same or greater than x + min. 6 cm. So: y ≥ x + min. 6. Fortunately, it's pretty simple maths!

Take a look at the table below. In the left column you can see the widths of the door openings, and in the following columns - the widths of the sliding doors.

  Door width
Door opening width 70 cm 80 cm 90 cm 100 cm 110 cm 120 cm 130 cm
80 cm ok ok ok ok ok
90 cm ok ok ok ok
100 cm ok ok ok
110 cm ok ok
120 cm ok

What is the difference between sliding and hinged doors?

If you are interested in interior design, or you have done preliminary research in the subject of doors, you probably know how the size of the hinged door is selected based on the opening in which it is to be installed, right? What does it look like with sliding doors?

Let's take a look at 80 cm door opening. The standard case.

In the case of the swing doors, their width will be smaller than the width of the opening by the difference resulting from the necessity to install the frame, i.e. 70 cm.

In the case of the sliding doors, their width will be greater than the width of the opening by at least 6 cm, i.e. 90 cm.


Finally, we leave you a few tips on the dimensions of the sliding door, which are worth collecting in one place to help you make the right decision.

  1. Better to choose wider than too narrow sliding doors.
  2. Keep in mind that the width of the track will be 2 times the width of the door - it must fit on the wall.
  3. The formula for the width of the sliding door is: y≥x + min. 6 cm.
  4. The height of the sliding door can be any, as long as there is approx. 15-22 cm above the door to the ceiling.
  5. You can order sliding doors in custom size - if you do not see your model in the offer, just send a request for quotation.
