Oak Doors for the Widest 33 Inch Openings
At 838mm, or 33 inches, this is the widest of the standard internal door widths, a step up from the common 762mm (30 inch) leaf and the wider 813mm (32 inch) size. It suits larger rooms, main hallways and grander openings, where a standard door can look a little narrow and a broader leaf reads as generous and well proportioned. It sits at the top of our range of popular door sizes, and these doors come in the standard 1981mm (78 inch) height. Because it gives the most generous clear opening of the standard sizes, it is also the width most often chosen where easier access matters.
Larger Rooms and Easier Access
A broader leaf changes how a doorway feels and works. In a large room or a main through-route it keeps the proportions right, and because the clear opening you actually pass through is wider once the frame is allowed for, it makes moving furniture and everyday movement easier. That same generous opening is why the widest leaves suit step-free and wheelchair use, and you will find the guidance and the doors best suited to it in our wheelchair accessible doors collection. If your openings are narrower, the range steps down to the standard 30 inch (762mm) door and the wider-than-standard 32 inch (813mm) door, and for an opening wider than a standard leaf, or an odd size, a made-to-measure door can be built to fit. A few things worth checking before you order:
- Measure the structural opening, not the old door, as a 33 inch leaf needs a wider frame and reveal than a standard door.
- Confirm the height as well as the width: these doors come in the standard 1981mm (78 inch) height.
- Decide on construction, solid oak throughout or an oak veneer over an engineered core.
- Choose a finish, prefinished for hanging straight away or unfinished to oil once it is hung.
Styles and Construction to Choose From
Most of the main styles are made in this width, so choosing the widest size does not limit the design you can have. You will find panelled oak doors and traditional period designs, cottage and ledged styles, shaker looks, and glazed oak doors that borrow light between rooms, in both solid oak and oak veneer. Solid oak doors are oak throughout and can be trimmed and refinished over the years, while oak veneer doors face an engineered core that helps a broader leaf stay stable and flat. Where building regulations call for one, certified FD30 fire doors are made in this width too, always as an oak veneer over a fire-resisting core rather than solid oak, as the core is what carries the certification.
Finishing and Hardware
Unfinished oak doors are ready to seal once they are hung, and the finish you choose makes a real difference to how the oak wears. We recommend a hardwax oil such as Treatex, which protects the wood while keeping the grain visible and is easy to refresh in years to come, rather than a stain, varnish or lacquer. You will find oils and care products in our door treatments range, and matching handles, hinges and latches to finish the job in door hardware.
Yes. 838mm is the metric equivalent of a 33 inch door, so the two describe the same leaf width. You will see both used across the range.
838mm (33 inches) is the widest of the standard internal widths, so it is chosen for larger rooms, main hallways and grander openings where a standard door would look a little narrow, and for the most generous, easy-access clear opening. If you need something narrower, the range steps down through the standard 30 inch and other sizes.
They are among the best choices. Because the clear opening you pass through is narrower than the leaf, the widest leaves give the most generous clear opening, so a 33 inch door suits step-free and wheelchair access. See our wheelchair accessible doors collection for the guidance.
