Replacing a door seems like a simple task, which is why many people decide to do it themselves. Unfortunately, not everyone succeeds! How can you replace a door and avoid mistakes? Find out what to look out for and what kind of opening you should prepare for an 80-series door!

Installing an 80-series door—where to start?

Have you decided to tackle home renovation projects on your own? Replacing a door panel shouldn’t be a problem, as it doesn’t require specialized knowledge. However, before you begin installing the door, you need to know that the door opening is one of the key factors determining whether the door will be installed correctly. The height and width of the opening are not the same as the door’s dimensions. The opening must be selected based on the wall thickness and the type of door frame. That’s why it’s so important to determine its dimensions correctly. This will help you avoid having to make corrections later on due to an incorrectly measured opening.

Adjustable door frame—where can it be installed?

One type of door frame is the adjustable frame. It can be installed in areas with non-standard wall thicknesses. You can adapt it to the architectural requirements of any building. It works great, for example, with walls that aren’t properly leveled. Thanks to its features, you can easily solve this problem.

What’s more, the adjustable door frame is equipped with clamps that wrap around the facade on both sides. This looks more aesthetically pleasing than with a fixed model. However, it’s worth noting one limitation here—the wall cannot be thinner than 7.5 cm.

Standard-width fixed door frame

The second type of door frame is the fixed frame. It has a specific width that is tailored to the standard wall width. It is also called a “block” frame because it works best in buildings with facade thicknesses ranging from 6 to 10 cm. Installing the door frame is very easy, but properly aligning all the components can present some challenges.

One drawback may be the lack of cover strips, which are typically used to conceal the joints. In this case, you’ll need to purchase decorative trim separately, which entails additional costs.

What size opening for an 80-cm door—door opening dimensions

How do you prepare an opening for an 80-cm door with different door frames? What matters here are the height and width of the opening.

Adjustable door frame

For an adjustable door frame, the wall openings must be about 8 cm wider than the door panel. This means the opening should be about 88 cm wide and up to 207.5 cm high.

Fixed door frame

With a fixed door frame, the opening must be even larger. The width of the recess should be 11–11.5 cm wider than the door panel. In this case, the opening in the wall should be 91 cm wide and 207.5–209 cm high. Remember to measure the height after the renovation is complete.

What to do if the opening for an interior door is too small?

If the door opening turns out to be too small, you can:

• widen it—this won’t be a problem with partition walls, but it will involve additional work and costs. With a load-bearing wall, you’ll need to check whether widening it would compromise the building’s structure;
• replace the door—replacement can be troublesome if the door was custom-made or specially ordered. For standard models, the seller should accept the return.
