The standard entrance door width in most Canadian homes is 36 inches, a full three feet, paired with an 80 inch height. That single measurement covers the majority of front entries you will ever walk through, which is exactly why it trips people up when their opening does not match it. If you are comparing entry door styles and sizes for your home, the width is the first number worth getting right, because it decides whether a door is an off-the-shelf swap or a custom order.
Height, sidelites, double configurations, and a few building rules all bend that baseline. Here is where the 36 inch standard actually applies, when you should size up, and how to measure your rough opening before you fall for a door that will never fit.

What Is the Standard Entrance Door Width?
The standard entrance door width for a single front door is 36 inches. That gives you a comfortable opening for moving furniture, greeting guests, and meeting accessibility needs without feeling cramped. Some builders use a 32 inch or 34 inch door on secondary or side entries, but the front door of a house is almost always 36 inches in newer Canadian construction.
The number that matters when you shop is not the door slab alone. It is the rough opening, the framed hole in the wall. For a 36 inch door, the rough opening is usually about 38 inches wide to leave room for the frame and shims. Mix those two measurements up and you will order a door that is either two inches too big or two inches too small.
Quick Take
A 36 inch wide by 80 inch tall single door fits most homes. Measure your rough opening, not the old slab, and expect roughly two inches of extra framed width around a door of that size.
Common Entry Door Sizes at a Glance
Doors come in a small set of common sizes, then everything else is custom. This table covers the configurations you will run into most often when you replace a front entrance. Widths for sidelites and double setups are the total framed opening, not the single door leaf.
| Configuration | Typical Width | Typical Height | Where It Fits |
|---|---|---|---|
| Single entry door | 36 in (3 ft) | 80 in (6 ft 8 in) | Most front entries |
| Narrow single door | 30 to 32 in | 80 in | Side and secondary doors |
| Tall single door | 36 in | 96 in (8 ft) | Modern high-ceiling homes |
| Door with one sidelite | 48 to 60 in overall | 80 to 96 in | Extra daylight and presence |
| Door with two sidelites | 60 to 75 in overall | 80 to 96 in | Symmetrical grand entries |
| Double entry door | 60 to 72 in overall | 80 to 96 in | Wide statement entrances |
Notice that height jumps in fixed steps too. The 80 inch door is the long-standing default, while the 96 inch door has become popular in newer builds with taller ceilings. Going taller usually means going custom, and it changes the look of the whole facade, so it is worth seeing the proportion in person before you commit.
Did You Know
Door sizes are quoted in imperial across most of the North American market even though Canada is metric. A “three-oh, six-eight” door is trade shorthand for 3 feet 0 inches wide by 6 feet 8 inches tall. If a supplier rattles that off, they mean the plain 36 by 80 inch door.
Why 36 Inches Became the Default
The 36 inch front door is not an accident of style. It is the width that lets a wheelchair, a couch, or a fridge pass through without a fight. Anything narrower starts to feel tight the moment you carry something bulky, and a 32 inch door in particular will have you turning appliances sideways and holding your breath.
There is a resale angle too. Buyers read a wide, well-proportioned front door as a sign the house was built or renovated properly. A cramped or oddly narrow entrance reads as a compromise, even to people who could not tell you why it bothers them. When you upgrade a front door, a professional front door installation and replacement service keeps the new unit square, sealed, and sized to the opening so the width actually works the way it should.
Pro Tip
If your current front door is 32 inches and the framing allows it, widening the opening to fit a 36 inch door during a replacement is one of the least glamorous upgrades that pays off every single day. Movers, deliveries, and future accessibility all get easier.
When You Need a Custom or Wider Door
Plenty of homes cannot use a stock door. Century houses, custom builds, and heritage properties often have openings that ignore modern standards entirely. If your measurements land between the common sizes, or you want a grander entrance, custom sizing is the answer rather than forcing a stock slab to fit.
A few situations that usually push you toward a custom or oversized door:
- Your rough opening is wider or taller than any stock size, common in older and architect-designed homes.
- You want a wider single door for a dramatic entry, in the 42 inch range rather than the usual 36.
- You are adding sidelites or a transom and need the whole assembly built to one exact framed opening.
- You are moving to a double door and want two matched leaves centred perfectly in the wall.
- Accessibility goals call for a wider clear passage than a standard door delivers.
Wider is not automatically better. A very wide single door gets heavy, and that weight puts strain on hinges and the frame over years of daily use. Past a certain point, two matched leaves in a double front door configuration for wide openings make more sense than one oversized slab, both for looks and for longevity.
Save Your Money
Before you commit to custom, confirm your opening really is non-standard. People often assume their entrance is unusual, measure loosely, and pay a custom premium for a door a stock size would have covered. A careful measurement first can keep you in the far cheaper standard-size lane.
How to Measure Your Entrance Door Opening
- Measure the width of the existing door slab itself, edge to edge, at the top, middle, and bottom. Use the widest reading.
- Measure the height of the slab from top edge to bottom edge on both sides.
- Measure the rough opening if the door is out: the framed width and height of the hole in the wall, stud to stud.
- Check the door thickness. Most exterior doors are 1 and 3 quarter inches thick, and hardware is sized to match.
- Note the swing and hinge side, since a replacement has to match how the door opens unless you rebuild the frame.
- Write every number down with a note of where you took it. A supplier can size a door from clean measurements, not guesses.
If any of your width readings disagree by more than a small margin, your frame may be out of square, which is common in older homes. That is a sign to bring in a pro rather than order online, because a new door forced into a racked opening will bind, drift, or leak air within a season.
Width Rules Worth Knowing Before You Buy
Front doors on a typical house are not tightly regulated on width, but the moment a door is part of a required exit or a barrier-free path, minimums kick in. Building codes set a minimum clear opening for exit doors so people can get out safely, which is one more reason the generous 36 inch door is the sensible default. For the exact requirements that apply to your project, the Ontario Building Code regulation is the authority, and your municipal building department confirms the local specifics.
Accessibility is the other reason to think in terms of clear width, the actual gap you pass through with the door open, not the nominal size. Hardware, stops, and the door thickness all shave an inch or two off the number on the box. If barrier-free access matters for your household now or later, plan around clear width and you will not be caught short.
People Often Ask: Is a 36 Inch Door Actually 36 Inches of Opening?
No. A 36 inch door gives you a clear opening a bit narrower than 36 inches once you account for the door thickness resting against the stop and the frame itself. Expect roughly 34 inches of true clear passage. For accessibility planning, always work from the clear opening, not the door’s nominal size.
