What is The Standard Size Door?

Few people know that the size of their doors is regulated by IRC. This is a set of rules that you must follow when designing and building a residential property.

The state usually enforces these at the state level and sets rules to ensure that buildings comply with health and safety guidelines, which is why door sizes in the United States are fairly standard, at least meeting the region code minimum dimensions. This guide covers standard size door and entry sizing issues.

Standard external size door

In the United States, the standard “external door” height is 80 “high and 36” wide. However, the width can vary from 30, 32, 36 inches, which is the most noticeable, and anything outside of the frame is considered an exception.

However, due to changes in building codes and regulations, your porch may not necessarily meet these dimensions, especially if your home is more than several decades old.

Thickness ranges from 1 3/4 “to 2″.

The type of material can also affect the dimensions of the door. The height of fiberglass or steel doors, for example, is 6’8 ” and 8 ‘

It is imperative that your front door fits well, as a poorly fitted door can cause security problems as well as miss the weather!

Ideally, when you measure the door, you will find that it is a standard size. If so, a replacement can be easily obtained from hardware stores or home renovation centers.

Custom sizes

But don’t be upset to find that your door is “custom”. Take your measurements to your local and they’ll be sure to help you find the right one – although it may cost you a little more.

What is the most common interior door size?

For interior doors, the standard minimum height is also expected to be 80 “for standard widths of 24, 28, 30, 32, and 36”.

The standard thickness should be 1 3/8 “, although this can vary up to 1 3/4” if your door exceeds the 36 “width standard or the 90” height standard.

Most commonly, interior doors are 32 inches wide. Thus, the standard interior door size is 32 inches wide and 80 inches high.

People can clean a doorway of this size without touching the sides of the frame. If you want your home to be wheelchair accessible, each door must be at least 36 inches wide.

Most commonly, interior doors are 1⅜ ”thick. Other door thicknesses are available, such as 1½ “, 1⅝” and 1¾ “. Over-sized or particularly large doors (over 90 “high or over 36” wide) are usually thicker than standard size doors.

Door thickness becomes important when you order hardware such as door handles and hinges. Fire doors are also thicker than conventional interior doors.

Today cabinet doors are 96 “high and 30” wide, but doors in houses built before 1990 can be very narrow at just 18 “wide.

IRC, however, requires that the minimum door size for interior passageways (any door that allows movement from one room to another) must be at least 80 “(6’8”) and 28 to 32 “wide. This does not apply to toilet or bathroom doors.

Interestingly, the code doesn’t seem to determine the size of the bedroom doors, although it might make sense to choose a standard size unless you’re happy to bear the extra cost of custom-made units.

If you choose the replacement door (or doors) yourself, it is best to have accurate numbers to limit the possibility of purchasing the wrong size.

How do you measure for an exterior door?

For exterior doors, you may need to provide four different sizes:

  • Door “slab” size – the slab is the door itself, excluding any other hardware or frame.
  • The rough opening is the space between the wall posts to which the door block will be attached.
  • The opening in the masonry is the distance from brick to brick along the outer edge of the opening.
  • Block Size – You can calculate this number using the approximate values ​​of the opening and opening in the masonry and refers to the frame on which the door plate will be hung.

Measurements should be taken from top to bottom and approximately three points from side to side.

Oddly enough, although there are standard door sizes, this does not mean that all entrances will be standard, and this is where the side light combinations come in handy.

The entrance opening should leave the room at least 3/4 “wider and 3/8” taller than the door frame.

How do you measure for an interior door?

Measure for your interior doors should be an easier task than your exterior doors (unless you are replacing the frame as well, in which case you will need to follow the instructions for exterior doors), although this should still be as accurate as possible.

Assuming you are only replacing the “floor” itself, simply write down the height, width, and thickness of the existing door. It’s also a good idea to write down the dimensions of the frame so that you can compare them with other shapes, and take at least three measurements in width, top, middle, and bottom. Not all doors (or frames) are perfectly rectangular, so minor adjustments may be required to fit perfectly and function properly.

When replacing double-leaf doors, take extra care when measuring! The standard heights for these are still 80 inches, although there is no standard width, the most common are 60, 64, and 72 inches.

French doors fall into the same category as walk-through doors, with standard sizes of 80 “by 36” – especially French doors leading outward. They will most likely be 1 3/4 inches thick.

The process of selecting new doors doesn’t have to be tedious — in all likelihood, your existing blocks will fit standard sizes and replacement will be easy. If they are non-standard, all is not lost! Most retail outlets and suppliers are ready to help you find the perfect doors to decorate your home.

What size interior door do I need?

Moving from a single door to a double door can make your home more sophisticated and elegant. A larger door, even if it’s increased from 32 to 36 inches, can make your home more open while giving you more room to receive guests, carry groceries, or new furniture.

Converting one door into a double-leaf entrance will add aesthetics and diminish the appeal of your property. A wider door will also make your home more accessible – 32cm to 36cm – and give you more room to greet guests or bring heavy luggage, groceries, furniture, strollers, and the list goes on.

However, if your foyer is small, looking through a double door may not be the best option, especially if you have stairs, dressers, or other inventory to keep it cramped. Besides functionality and comfort, you have style and a beautiful look. Unfortunately, not every entrance needs a new size door.
