Fabricated Gates & Doors: Standard Sizes for Residential Homes

A door or gate may seem like a simple enough installation and many homeowners tend to forget that it too needs to be designed, fabricated and installed with care.

Fabricated gates & doors- aspects to consider

There are some basic factors that have to be taken into account when purchasing a door, such as – the style and type of door and whether it should swing outwards or inwards. Once you have made your choice on these points, you would have to start measuring.



While you do have the option to get fabricated gates & doors in custom sizes, we at Boston Ironworks have seen that most homes have standard door openings and require standard door sizes as well. Take a look at some of the door sizes available:

1. Exterior doors and French doors
