Window Door Sizing Guide

 

Window Door Sizing Guide

Most windows and doors in the UK belong in a standardised set of sizes, – for example, system homes typically contain the largest-sized windows allowed in accordance with UKAS test specifications, whilst homes built by the council should use the same door size (2040mm x 526mm) – and all homes should contain window/door sizes within the building regulations guidelines.

Window Sizes:

When upgrading window frames or redesigning a property to include uPVC windows, the following heights and widths are commonly used: window door sizing guide

What sized window(s) should I choose?

Ordinarily, when people are looking at a window door sizing guide, most people will choose the same window size their previous window fitted to their frame, which is cost-effective and guarantees no discrepancies when complying with UKAS specifications and other building codes, assuming there were no prior issues with the prior windows before. However, multiple factors need consideration when opting to change the size of your windows.

Larger windows may be preferable in a large room to allow more natural light to enter; the glazing must offer noise reduction to allowable sound levels per room and position; clearance will need to be made for an internal and external radius the windows will occupy if they are tilt-and-turn style, and new window sizes will need to be within UKAS and building regulations guidelines. window door sizing guide

Door Sizes:

Sizes of doors in the UK are quite varied and are dependent on the function of the doors themselves, and the wall heights of the rooms into which they are fitted. These are some examples of door sizes best suited for certain purposes:

1981 x 457/533 x 35mm – usually for cupboard and wardrobe doors.

1981 x 610/686 x 35mm – this measurement is commonplace for doors when the wall space is restricted.

1981 x 762 x 35mm – most referred to as a 2’6”, this door is the most common internal door size in England and Wales.

1981 x 838 x 35mm – under normal circumstances, this door size provides the required opening width for wheelchair access under the Approved Document M mobility requirements.

What sized door(s) should I choose?

The door size you choose will be limited by the height of your walls per floor of your property, although this is only important if your ceiling is exceptionally shallow, and you desire a tall door. All you need is to ensure there will be enough space to open and close your new door design. window door sizing guide
