Are internal doors a standard size? Made to measure explained

The standard door measurement for lifestyle dwellings is 1981mm by 762mm (also known as a 2' by 6' door). But are internal doors a standard size? Not exactly. Dimensions do vary but are largely dictated by Building Regulations and accessibility requirements, such as Part M, which provides minimum size restrictions to ensure clearance for comfortable movement. Trade supplies typically offer a limited range of sizes, within this remit, to fit straightforward builds. However, for irregular or unconventional doorways – like those in older or architecturally unique homes – standard doors can fall short, with projects warranting grander, more ambitious designs.

Take a traditional, period property with an uneven annexe opening, for example – a doorway where the frame may not be perfectly rectangular, or where the height and width don’t conform to typical modern measurements. With an off-the-shelf solution, this uneven structure might create gaps or misalignments that are not just unsightly but affect your home’s functionality and performance. To accommodate these quirks, you might be tempted to make substantial alterations or compromise on design. But with Deuren, these limitations don’t apply. We handcraft doors that fit the architecture, not the other way around.

When navigating awkward spaces or unique openings, some may be tempted to cut standard doors down to size. But hacking into high-quality hardwood is far from ideal. Not only can you compromise the structural integrity of the door, but you can also create draughty gaps, uneven finishes, and an overall look that feels unfinished. 

This is where Deuren’s precision-engineered, made-to-measure internal doors come in. Every door we manufacture is handcrafted with your specific measurements – so no planing off edges or compromising on the quality of your materials. Instead, you’ll receive a door fitted seamlessly into its frame, with every millimetre (if not micrometre) accounted for. From grand pivot designs to space-saving bi-folds, unlock limitless options as unique as your home itself.

When designing a bespoke home, every detail matters – this includes the doors that define each room. Opting for pre-hung door sets not only elevates the aesthetic of your space but also streamlines the installation process. Delivered as a complete unit, each pre-hung door comes meticulously assembled with its lining (or frame), stop beads, and architraves, as well as premium quality handles and hardware, all perfectly aligned and ready to be fitted.

Crafted with the same uncompromising attention to detail as all of our bespoke designs, our pre-hung internal doors ensure seamless, flawless integration into your home, preserving the purity of your one-of-a-kind design. The result? A cohesive, luxurious aesthetic where every door becomes a statement piece, harmoniously complementing your home’s vision. When you choose Deuren, you’re not just choosing superior aesthetic quality, but also the reliability and refined craftsmanship that transforms your bespoke space into a true work of art.

Precise measurements are essential for made-to-made measure internal doors – not just for providing an accurate quote, but for ensuring a flawless fit. To measure an internal door opening, be sure to check the width, height, and depth of each doorway, accounting for any structural variations. For pocket doors, you’ll also need to factor in additional space requirements, such as the depth of the wall cavity and clearance for the door to slide, ensuring a clean and elegant finish when the door is fully open. The ultimate goal is to capture the exact dimensions of the space where the door will sit, making sure every component – including the architrave and the leaf – fits seamlessly into the opening. Rest assured, we’ll survey the site and confirm precise measurements after your initial quote.

Of course, this level of precision isn’t always possible at the early stages of a project, and knowing how to measure internal doors is even trickier if construction is yet to begin. Since we recommend getting in touch from the earliest design phase, many clients may not yet have fully defined their doorways. For architects and self-builders, collaborating with Deuren at this stage means we can help map out your door requirements long before the walls are even up – ensuring every detail, from hinge placement to material choice, is in sync with the architectural vision. This way, you can unlock even more options that integrate as the build progresses.

Choosing bespoke internal doors is more than simply avoiding the limitations of standard sizes. It’s about creating a cohesive vision for your home – a place where each detail works together to create something genuinely unique. Deuren offers a wide variety of made-to-measure options to help you achieve this level of personalisation, from sleek glass doors that flood your space with natural light to full-height configurations that serve as a striking focal point, redefining room entryways.

Our clients appreciate that every door can be customised, not only in size but in finish, material, and style. With options for fire-rated models, intricate inlays, or custom textures, each door becomes a reflection of your taste and your home’s character, combining form and function to elevate your dream space.
