Double Door Sizes in Metres: Find Your Perfect Fit

By Ashley YoungMarch 25, 2026

When it comes to home improvement or new construction, one of the most crucial aspects to consider is door size. This is particularly important when it comes to double doors, as they not only serve a functional purpose but also significantly impact the aesthetics of your space. But how do you determine the right double door size in meters?

Firstly, it's essential to understand that double doors are typically measured in two ways: width and height. The width refers to the total distance between the two door jambs, while the height is the distance from the floor to the top of the door frame. In this article, we'll delve into the intricacies of double door sizes in meters, helping you make an informed decision.

Understanding Standard Double Door Sizes in Metres

Before we dive into the specifics, it's crucial to understand that there are no universally accepted standard sizes for double doors. However, there are some common sizes that you'll find in many homes and buildings.

In Europe, for instance, double doors are often 900mm wide, with each door leaf measuring 450mm. The height typically ranges between 2000mm to 2100mm, depending on the specific application. However, these sizes can vary significantly, especially in commercial settings or when architectural design calls for something unique.

Residential Double Doors

In residential settings, double doors are often used as entryways or to connect different rooms. Here, the size is usually determined by the width of the doorway and the need to accommodate furniture or other large items that might need to pass through.

For example, if you're installing double doors in a standard 800mm wide doorway, you might opt for two 400mm wide door leaves. However, if you're looking to create a more grand entrance, you might choose wider door leaves, such as 500mm or even 600mm wide, with a total width of 1000mm to 1200mm.

Commercial Double Doors

In commercial settings, double doors are often used for wider access points, such as entrances to offices, shops, or public buildings. Here, the size is typically determined by the need to accommodate large equipment, furniture, or high volumes of people.

For instance, you might find double doors that are 1200mm wide or even wider, with each door leaf measuring 600mm or more. The height might also be taller, at 2200mm or more, to accommodate taller individuals or equipment.

Factors to Consider When Choosing Double Door Size

When choosing the size of your double doors, there are several factors to consider beyond just the width and height.

For instance, you'll need to consider the door swing. Double doors can swing inwards or outwards, and this can impact the space they require. Inwards-swinging doors need less space but might impede on the room they open into. Outwards-swinging doors require more space but don't take up room inside the room they open into.

Door Clearance

Another crucial factor to consider is door clearance. This refers to the space that the door needs to open fully without obstruction. For instance, if you're installing double doors in a narrow hallway, you'll need to ensure that they can open fully without hitting the walls or other obstacles.

Similarly, you'll need to consider the clearance above the door. If the door is too tall, it might hit the ceiling when opened. Conversely, if the door is too short, it might not provide adequate privacy or security.

Door Hardware

Finally, you'll need to consider the door hardware. The size and type of hardware you choose can impact the overall size of the door. For instance, if you choose a lever-style handle, you'll need to ensure that the door is tall enough to accommodate it.

Similarly, if you choose a heavy-duty lock or a smart lock, you'll need to ensure that the door is sturdy enough to support it. This might mean choosing a thicker door or reinforcing the door frame.

In the end, choosing the right double door size in meters is all about balancing functionality and aesthetics. By understanding the standard sizes and the factors that impact your decision, you can make an informed choice that enhances your space and meets your needs.
