Tips For Choosing the Right Internal Door

Internal doors are often overlooked when it comes to redecorating the rooms in your house. A well-chosen interior door is the difference between a redecorated room that looks nice and a redecorated room that looks polished, sophisticated and stylish. 

 There is a tremendous amount of door styles to choose from on Express Doors Direct so it's easy to understand why you may have a list of questions you need answering before you chose your new internal doors. A good door is obviously an essential part of a room and adds a lot to the end result of your interior design. The trim, the panels, the glass, the material and the finish will all be things you'll want to consider before making your purchase.  

You'll need to ascertain more practical factors as well, such as if you want the door to provide privacy or light, or be thicker or glazed. 

What Style of Internal Door Will I Need?

It's not just practical things that you will need to think about when picking your door – but also what style you want. Do you want a standard door? Because internal bi-folding doors or French doors are also an option if you have enough space for them. Make sure you understand the different types of internal door available before you make your decision.  

If you do opt for the standard design, do you want heavy, solid oak internal doors, ornate Victorian doors, doors with glass panels, stile-and-rail designs with feature panels, or the more economical flush door with a faux hardwood veneer? 

Plain and practical, flush doors are certainly one of the most affordable options we have available. They tend to be hollow, which makes them lightweight and easy to work with – it does, however, mean they might not be able to be trimmed. A solid would option will give you more flexibility should you need to need to trim the door.  

If you live in a period property and have a smaller or narrower door frame than standard modern sizes, then you might need to consider a door that can be trimmed.  

What Material Should I Choose For My Internal Door?

The materials you chose for your internal door will obviously depend heavily on the place in which the door is going – if you need it for a hallway, for example, you might consider a wood that is fairly heavy to block of noise from the outside. Heavy oak internal doors are a practical option for noise reduction,  

A more contemporary option is a pale wood material or a white glazed material – this will give your house a far more modern and minimalist finish than traditional oak. Internal doors with a hollow core, or lightly glazed doors which tend to be of a lighter material, look lovely and might be a good choice for a bedroom or living room where children will need access and you'll need to be able to hear through them.  

Internal doors with glass panels in them are a lovely way of letting light into a room while still allowing the option of privacy, which might be suitable for a dining room or living room.  

Glass sliding doors are a great option for a dining/living room or a room that leads onto a patio is the best way of saving space and linking the two spaces together.  

What Size Internal Door Do I Need?

Presumably, once you have chosen the style of interior door you'd like, then the next step is deciphering what size you need for the door frame you have.  

There are ways to go about trimming some door styles, so keep that in mind. This creates a little extra work, but we have some helpful advice on how to go about doing this. We offer a huge array of most standard door sizes, and the solid door options are likely to be able to be trimmed or sanded slightly if you have a period property that has unusual door sizes.  

Standard Metric Door Sizes  

Metric sized internal doors have grown in popularity over the past few years, especially in Europe and Scotland. Metric sizes doors have small differences, with an increased door height of 2040mm and a thickness of 40mm.  

  • 2040 x 526/626/726/826/926 x 40mm 

 Other Door Sizes  

Although these probably won't affect most of our customers, there are some standard door sizes that you might see crop up when browsing our interior door ranges.  

  • 1981 x 610/686 x 35mm – door sizes are used where the wall space may be restricted, and a smaller door is required. 
  • 1981 x 762 x 35mm - often referred to as a 2’6” door is the most common internal door size in England and Wales. 
  • 1981 x 838 x 35mm – in most circumstances provides the required opening width for wheelchair access under the Part ‘M’ mobility requirements.  You may also hear this door size being referred to as a 2’9”. 

Fire door standard sizes 

All the standard UK and metric door sizes are usually available as a fire door equivalent with the only difference being an increased door thickness of 45mm.  This is because extra core component materials are required in the construction of the door to achieve its’ fire rating.  Remember to check that your frames, intumescent seals and ironmongery also comply with the door’s fire certification.

Other Things to Consider

Another thing to consider which may sound trivial is the way the door opens. You might decide a pocket door that slides in on the wall, which saves a huge amount of space but might not be possible depending on the design of your room. A bypass door is an option; it has a staggered design where the doors slide past each other. Perhaps a bi-folding internal door is more suited to your needs. A bifolding door design in which the doors hinge in the middle and have one fixed lead door, this opens up a room and gives the effect of more light and space. Just remember the whichever way your doors open, you'll need a decent amount of space to allow them to open and if you have a small room then a traditionally opening door might not be the best option.  

Another aspect worth thinking about is internal door sizing – the type and style of door you chose might be dependent on the size of the frame you have. Internal bi-folding doors make the best option for a larger frame that divides two rooms, whereas a classic oak door might be better for a standard door frame. Most of our ranges have door styles that offer multiple options in one range, so you can pick and choose between clear or glazed, frosted finishes, unglazed, single leaf and bi-folding options to create a consistent feel throughout your home.  

And finally, what you need to consider is your budget – when looking to replace your old and tired doors for throughout your entire house, then finding the most affordable and cost-effective options might be the top of your priority list. Consider choosing unfinished doors to keep the costs down, and then you can stain or glaze them yourself.  

If you find a style you like, then most of our doors have unfinished options – so you can get the doors you want even with a modest budget.
