Do double opening doors require a lot of space to open? Well, that's a question I get asked a whole bunch as a double opening door supplier. In this blog, I'm gonna dive deep into this topic and give you the low - down on how much space these doors really need.

First off, let's talk about what double opening doors are. They're basically two doors that are side by side and can be opened independently or together. They're super popular in a lot of different settings, from homes to commercial buildings. You can use them as interior doors to divide large rooms or as exterior doors to make a grand entrance.

One of the most common concerns people have is the space needed for these doors to swing open. You see, traditional single doors usually swing in one direction. But double opening doors have two leaves that need to move. So, at first glance, it might seem like they need a ton of space.

Let's start with the standard swing - style double opening doors. When both leaves are opened fully, they form an almost 180 - degree arc on either side. This means you need to have clear space in front of the door on both sides. For example, if you have a double door that's 6 feet wide in total (3 feet per leaf), when you open both leaves, you'll need at least 3 feet of clear space on each side of the door for them to swing without hitting anything. That's a fair bit of room, especially in smaller spaces.

But here's the thing, not all double opening doors are created equal. There are different types that can help save space. Take the Double Door with Unequal Leaves. In this design, one leaf is usually larger than the other. The smaller leaf can be used more frequently for normal traffic, and it doesn't require as much space to open as a full - sized leaf. This way, you can get the functionality of a double door without using up too much space all the time.

Another option is the Double Skin Door. These doors are designed with an extra layer, which can sometimes be used to house mechanisms that allow for different opening styles. Some double skin doors can be made to slide open instead of swing. Sliding double opening doors are a great solution for spaces where there's limited room in front of the door. They run on tracks and only need the width of the door itself in terms of side - to - side space.

Now, let's think about the installation location. If you're installing double opening doors in a hallway, you really need to be careful about the space. Hallways are usually narrow, and if you have standard swing - style double doors, they can block the passage when opened. In this case, sliding or pocket double doors would be a much better choice. Pocket double doors slide into a recess in the wall, so they don't take up any floor space at all when opened.

In a living room or a large entryway, you might have more flexibility. You can afford to have standard swing - style double doors because there's usually more space around. But even in these larger areas, you still need to consider furniture placement and traffic flow. You don't want the doors to hit a sofa or a table when they're opened.

When it comes to commercial spaces like offices or stores, the space requirements are even more critical. In a store, for example, you need to ensure that customers can move in and out easily. If the double opening doors take up too much space when opened, it can cause congestion and make the shopping experience less pleasant. That's why many commercial buildings opt for automatic sliding double doors. They're not only space - saving but also convenient for customers, especially those with their hands full.

Let's also talk about the angle of opening. Not always do you need to open double doors fully. In many cases, opening them partially is enough. For instance, if you just need to let a single person through, opening one leaf slightly or both leaves just a little bit can work. This reduces the amount of space needed in front of the door at that moment.

So, to sum it up, double opening doors don't necessarily require a whole lot of space to open. It really depends on the type of double door you choose, the installation location, and how you plan to use them. If you're short on space, there are plenty of options like unequal - leaf doors, sliding doors, or pocket doors that can fit the bill.
