Interior Doors Thickness mm: A Guide to Choosing the Perfect Door for Your Home
There is one design element that can quickly upgrade the overall look of your home, and that is the
interior doors
, which come in a variety of styles, textures, shapes, and sizes. Typically, most interior doors range in
thickness from 1-3/4” to 2-1/4”
, with this dimension changing depending on the type of door chosen. The standard
thickness of an interior door
is 1-3/8” and is perfect for rooms that do not require a larger or bulkier door such as a closet. The added weight and insulation added from a thicker door often make them the preferred choice for rooms such as a master bedroom or bathroom.
One of the advantages of a thicker interior door is the added level of security it provides. Softer woods such as pine, for example, often require thicker doors to withstand greater levels of security, as well as
soundproof
. The added thickness also increases the stability of the door, helping it resist warping and shrinking. It also allows heavier floors to be used on the bottom of the door which helps prevent drafts, dust, and pests from entering the home.
The Popularity of 2-1/4” Thick Doors
The most popular door thickness is 2-1/4”, which is the standard size for any traditional or commercial-grade interior doors. These doors are also commonly found in the modern home, offering an inviting ambiance that adds to its overall charm. 2-1/4” doors are typically the most expensive due to the extra engineering required to make them thicker, providing a longer life and improved strength, while also offering a more stylish look.
Choosing the Right Measurements for Your Door
Measurement is key when it comes to selecting the right interior door thickness. Not only are the door sizes standardized, but homeowners should also look for variations in thicknesses based on the type and purpose of the door. After all, a door in a bedroom may require more insulation and security than a door in a bathroom, which can often have its own unique specifications.
When it comes to choosing the correct door thickness, measuring the door will be critical to achieving the desired level of sturdiness and insulation. It is important to understand that, with interior doors, the measurement taken will represent from the door jamb to the door stop, rather than the entire thickness of the door itself.
Measuring the Doorjamb
In order to get the correct measurements for an interior door, you should begin by measuring the doorjamb first. This will help you determine the thickness of door needed, as most doorjamb kits have guides to show the amount of door space required.
The next step is to measure the door frame to identify if the door space is currently too small or too large. If the space is too small you will need to adjust the doorjamb to increase the width of the door, or you can also purchase a door thicker than the minimum standard size of 1-3/4”.
Purchasing a Door
Once the measurements for the door space are taken and determined, it’s time to purchase the door itself. Generally, doors range in common thickness from 1-3/4” to 2-1/4”, while the standard thickness is 1-3/8”. The right door should be as thick as possible, without making the overall look of the door too bulky.
When shopping for a door, you should also keep in mind the construction of the door, as some may require more thickness to achieve the desired level of sturdiness and insulation. Different interior doors will also vary depending on the type of material they’re made of, such as wood, fiberglass, or steel, or the different interior and exterior door finishes, such as glass, decor panels, alternative woods, and more.
For those who want to go with a traditional look, the standard size of 1-3/8” is usually enough. For those wanting more security or insulation, a thicker door such as 2-1/4” may be warranted.
Installing the Door
Once the door has been purchased, it is time to install it. This is often a complex project that requires the work of experienced professionals. Every step needs to be done precisely,
