How to Select the Perfect Interior Doors

New doors can provide a refreshing change to your home decor. Whether you are remodelling your home or just looking to replace some old doors, you might be wondering how to pick the right interior doors to suit your home. We’ve put together this helpful guide to make the process easier.

Select Your Door Style

Doors can be used to bring out the character in your home, and there are so many different modern and timeless styles to choose from.

For a minimalist and contemporary look, consider a door with thin embossed lines or a door with a simple, flush design. Traditional doors with clean lines will coordinate easily with their surroundings, while familiar door designs will bring definition and universal appeal to any space.

Keep in mind how you want to finish your door—by painting or staining—as it can narrow down your choice.

Identify What Door Is Your Type

Your choice of door type will depend mainly on how you intend for it to be used.

There are two main types of interior doors:

  • Pre-hung doors, which include a frame-mounted door and hinges. This ready-to-install option should be used with a prepared doorway.
  • Slab doors, a basic option that includes only a door (but no frame, hinges, or handle set). Unfinished (which require painting or staining) or finished and ready to hang options are available.

For room entrances, for example, you will need a door that is pre-hung in the frame and properly aligned, while other applications may only require a slab door.

Open bifold interior doors leading to a living room
Bifold Door

Bifold doors are made up of two panels joined at the centre by hinges. The panels are set on tracks and open up into a "V" shape.

These types of doors are preferred when space is limited because they don’t need much clearance. They can also be hung in a series and used as room dividers. For more air circulation, choose louvred doors.

  • Finished on both sides
  • Louvred, half-louvred, or “French door” style
  • Smooth panels

  • May be installed as a single or double unit.
  • Typically sold with hardware and track.

Sliding Door

Also known as bypass doors, sliding doors are similar to bifolds because they don’t need a lot of clearance. Each door unit has two or three doors that slide on rollers. They ride on parallel tracks and open from the sides with one door sliding in front of the other, like patio doors.

Because they save on swing space, sliding doors are often found in closets. However, you will only be able to open one side at a time (or two sides on a three-door unit). Remember these points when installing closet sliding doors for kids or guest bedrooms.

Understand a Door’s Internal Structure

When choosing a door, you will also have the option between a hollow or solid core interior. The choice of core is important, as it affects a door’s soundproofing ability, fire resistance, impact resistance, and weight.

To find out if a door is hollow or solid, just give it a knock. The difference is instantly audible.

Hollow-Core Door
Hollow-core doors are the more common and economical option. These doors feature a wood, MDF, or veneer exterior while the centre core is made up of wood material or lightweight plastic tubing in a honeycomb structure. Some doors may also have wood support slats for the wood facing.
Illustration of a solid-core door’s components
Solid-Core Door
Solid-core doors have a solid interior that may be filled with solid wood, particle board, laminated wood, or polystyrene. A solid core door will resist warping, have a quality look and feel, and reduce the transmission of sound. It is a fantastic choice for the bedroom, laundry room, and bathroom.

Consider All Aspects Before Making a Choice

While door style and type are important aspects of an interior door installation, size and swing are also essential to consider.

Size

Today’s doors are manufactured in standard sizes for new homes.

Height

The standard height of a door is 80", though this can vary depending on factors like ceiling height. There should also be a ½" clearance between the bottom of the door and the floor.

Width

The standard width of a door is 30" but can range from 24" to 36" inches depending on your needs. For example, laundry room and basement doors are typically at least 32" wide to allow for moving large items like appliances and furniture.

36" wide doors are growing in popularity as well, especially among people who use wheelchairs and other mobility aids. 

If you opt for a door opening that is wider than 36", it is a good idea to install two doors instead of one. Keep in mind, as well, that the frame will add an extra 1" on either side for 2" in total.

Thickness

The thickness of a door depends on:

  • its latch system, and
  • the material used.

It can vary from 1" to 2" thick. Sliding doors also overlap when open, doubling in width.

Made-to-Measure Doors

You can order made-to-measure doors (like higher doors) in-store. However, it may also be possible to cut a standard door already available in-store to size, just make sure you choose a door that can be cut.

Door Swing

The "swing" of a door means the direction it opens in.

While replacement doors will have the same swing, it is important to choose wisely for a new installation. Make sure that there is nothing in the way of the door when it is fully open, like a wall, a piece of furniture, or a counter. The door also shouldn’t impede traffic between rooms and should allow for the movement of furniture. It is important to consider and weigh all aspects of the door installation before deciding whether the door should open in or out, and to the left or the right.

If none of these door swing options seem functional or practical, then a bifold, folding, or sliding door might be the better choice.
