Double-leaf door: dimensions and buying guide

Double-leaf door: dimensions and buying guide
Knowing the dimensions of double-leaf or single-leaf doors could prove useful for your next building renovation project or for furnishing your new home in style. 

In this article, we will explore the standard dimensions for hinged doors, when it is necessary to order a made-to-measure product, and finally the benefits of choosing a standard door.

Whether you’re renovating or building from scratch, knowing the standard dimensions allows you to navigate the market with confidence, planning every single detail with precision.

Standard dimensions for hinged doors

When we talk about standard hinged door sizes, we are obviously referring to all those dimensions that are widely used in modern construction and meet most housing requirements.

Most commonly available products on the market, in the interior door sector, adhere to two dimensions:

  • 70 cm or 80 cm: for bedrooms, studies and living rooms. They allow for easy passage and fit perfectly into most rooms;
  • 60 cm: used for utility bathrooms, storage rooms or utility rooms where space is limited.

The Ermetika xREVERx reversible flush-fitting hinged door meets these requirements perfectly: it is always in stock, and thanks to the reversible system, you can easily customise the door and reverse the opening direction (push or pull, right or left) with a simple action.

Dimensions for double doors

The situation is different if, for better use of space or for stylistic reasons, you opt to purchase a double-leaf door. In new-build projects, the need to adhere to standard commercial sizes can be addressed at the design stage.

In the case of a restoration project, however, the most appropriate choice for non-standard sizes may be to purchase a bespoke product.

A striking example might be a restoration project in a city with such historic charm as Venice. Sometimes it is essential to consult a professional such as Ermetika to purchase a bespoke, customisable product that reflects the style you wish to preserve (or create), given the property’s characteristics.

Height of double-leaf doors

Speaking more specifically of the standard height of interior doors in modern construction, whether double-leaf or single-leaf, the most common measurement ranges from 200.00 to 210.00 centimetres.

Again, if the project requires different dimensions, you can opt for a made-to-measure product that meets the customer’s needs. A practical example might be a request for a full-height double-leaf door to be installed in a living area with high, airy ceilings.

Width of double-leaf doors

We have previously examined the width of the standard hinged door, which, as we recall, varies depending on the type of room to be furnished.

When it comes to living/sleeping areas, the door should have a width ranging from 70.00 to 80.00 centimetres. For other types of spaces, such as a storeroom or bathroom, the dimensions may vary.

The same applies to double-leaf doors: depending on the available openings, if you wish to opt for a standard width, you can use two 60.00-centimetre panels, two 70/80.00-centimetre leaves (for openings ranging from 140.00 to 160.00 cm) or, if the stylistic choice.

Bespoke hinged doors: when they’re the right choice

We have almost reached the end of this guide, which has helped you understand the dimensions of standard hinged doors. However, if you want to give your design project that extra touch, you may need a bespoke product.

Before exploring all the benefits of using standard dimensions in your project, you might be wondering: when is it worth opting for a bespoke hinged door?

Opting for a bespoke product may be necessary in three different scenarios:

  • For large openings: creating an imposing entrance between two rooms;
  • Stylistic choice: where a full-height door can enhance the verticality and spaciousness of the room;
  • Building renovations and refurbishments: in historic settings where opening dimensions are non-standard.

Advantages of standard sizes for hinged doors

There are two main advantages to choosing a hinged door in standard sizes: the product’s wide availability on the market and lower purchase costs.

Manufacturers and retailers hold a large stock of standard-sized doors, drastically reducing waiting times. This translates to a quicker and more efficient installation.

As for the second point, the mass production of standard doors allows for optimised processes and reduced costs, making these products more affordable than bespoke solutions.
