Short answer. Canada has no single national minimum bedroom size. The National Building Code, which each province adopts in its own way, sets ceiling heights and hallway widths for homes but no room areas. Ontario's Building Code adds them: at least one bedroom of 9.8 m² (105 sq ft), or 8.8 m² (95 sq ft) with built-in cabinets, and other bedrooms of 7 m² (75 sq ft), or 6 m² (65 sq ft) with built-in cabinets. Cities set their own rules for rooms people sleep in: in Toronto, 6 m² (65 sq ft) for one person. No national survey gives an average bedroom size; for whole homes, Statistics Canada put condo apartments at 840 sq ft (78 m²) in Toronto and 854 sq ft (79 m²) in Vancouver.
Will a queen bed fit your bedroom?
The queen is the most common bed in Canada. Pick a bed and type your room's width and length.
| Bed | Size in cm | Size in inches | Good to know |
|---|---|---|---|
| Single | 96.5 × 190.5 | 38 × 75 in | Also called a twin. French: simple, jumeau |
| Twin XL | 96.5 × 203 | 38 × 80 in | A single 5 in longer, for tall sleepers. French: simple très long |
| Double | 137 × 190.5 | 54 × 75 in | Also called a full. French: double |
| Queen | 152.5 × 203 | 60 × 80 in | The most common size in Canada. French: grand, or simply queen |
| King | 193 × 203 | 76 × 80 in | The widest standard size. French: très grand, or king |
| California king | 183 × 213.5 | 72 × 84 in | Also called a western king. French: très grand californien |
A queen with 60 cm (2 ft) beside it on both sides and 50 cm (20 in) at the foot needs 2.73 × 2.53 m (8 ft 11 in × 8 ft 4 in), or 6.9 m² (74 sq ft). That is almost all of an Ontario 7 m² bedroom, with nothing left for a dresser. With comfortable walkways it needs 3.13 × 2.73 m (10 ft 3 in × 8 ft 11 in), or 8.5 m² (92 sq ft), which fits in Ontario's 9.8 m² main bedroom only if the room is at least that wide and that long.
Who sets room sizes in Canada
- The National Building Code is a model. Its 2020 edition, as British Columbia adopted it in 2024, sets ceiling heights and hallway widths for homes, but no minimum area for any room. BC's 2018 code, based on the 2015 edition, did the same.
- The provinces turn the model into law, with their own changes. Ontario's 2024 Building Code, in force since 1 January 2025, adopts the 2020 national code and keeps Ontario's own minimum room areas.
- Cities set property standards for homes people already live in, rented rooms included. Toronto and Brampton are two examples below.
Which edition applies to your home depends on your province and when the home was built. Ask your municipal building department.
Room sizes in Canada
Legal minimums, not typical sizes. Ontario's areas leave out closets and built-in bedroom cabinets.
| Room | Ontario minimum (2024 Building Code) | National code (2020, as in BC) | Good to know |
|---|---|---|---|
| Main (master) bedroom | 9.8 m² (105 sq ft), or 8.8 m² (95 sq ft) with built-in cabinets. Art. 9.5.3D.2 | No minimum area | Every home needs at least one. 9.8 m² is about 10 × 10 ft 6 in |
| Other bedroom | 7 m² (75 sq ft), or 6 m² (65 sq ft) with built-in cabinets. Art. 9.5.3D.1 | No minimum area | A bedroom combined with another room: 4.2 m² (45 sq ft). Art. 9.5.3D.3 |
| Living room | 13.5 m² (145 sq ft); 11 m² (118 sq ft) when it shares one space with the kitchen and dining area in a home for up to two people. Art. 9.5.3A.1 | No minimum area | Width matters more than area for a couch and a TV |
| Dining area | 7 m² (75 sq ft) as its own room, 3.25 m² (35 sq ft) when combined with another room. Art. 9.5.3B.1 | No minimum area | |
| Kitchen | 4.2 m² (45 sq ft), or 3.7 m² (40 sq ft) in a home for up to two people. Art. 9.5.3C.1 | No minimum area | |
| Bathroom | No set area: room for a sink, a toilet and a shower or bath | No minimum area | Ontario's own guide says this could be as little as 3.0 m² (32 sq ft) |
| Hallway | 860 mm (34 in) wide, or 710 mm (28 in) in some cases. Art. 9.5.4.1 | The same: 860 mm, or 710 mm | |
| Ceiling height | Living, dining and kitchen: 2.3 m (7 ft 7 in) over at least 75% of the required area. Bedrooms: 2.3 m over half of it, or 2.1 m (6 ft 11 in) over all of it. Table 9.5.3.1 | 2.1 m (6 ft 11 in) over the room or a set part of it: 10 m² (108 sq ft) of a living room, 4.9 m² (53 sq ft) of a main bedroom, 3.5 m² (38 sq ft) of another bedroom | In Ontario, bedroom floor under 1.4 m (4 ft 7 in) of headroom does not count toward the area |
| Whole home | A bachelor unit where living, dining, sleeping and kitchen share one space: 13.5 m² (145 sq ft) for up to two people. Art. 9.5.3E.1 | No minimum area | Statistics Canada (2019): condo apartments 840 sq ft (78 m²) in Toronto, 854 sq ft (79 m²) in Vancouver; Ontario condos built in 2016 and 2017, a median of 665 sq ft (62 m²) |
City rules for rooms you sleep in
- Toronto (Municipal Code Chapter 629, Property Standards): a room one person sleeps in must be at least 6 m² (65 sq ft), with one side at least 2 m (6 ft 7 in). Two or more people need 4 m² (43 sq ft) each. Overall, a home may house no more than one person for every 9 m² (97 sq ft) of habitable room floor. Rooms need 1.95 m (6 ft 5 in) of height over at least half the floor, and floor under 1.4 m (4 ft 7 in) does not count for a sleeping room.
- Brampton (Property Standards By-law 165-2022): a sleeping room must be at least 7 m² (75 sq ft), or 6 m² (65 sq ft) with built-in closets; 14 m² (151 sq ft) for three adults; 7 m² per person for four or more.
Other cities have their own bylaws. If you rent out a room, check yours.
How floor area is measured in Canada
- The building codes measure a room between the finished wall surfaces. Ontario's minimum areas leave out closets and built-in bedroom cabinets.
- New homes in Ontario follow the Home Construction Regulatory Authority's floor area rule (since 1 February 2021). A condo unit is measured to the centre of the walls it shares with its neighbours and to the outside face of the corridor wall; a detached house to the outside face of its exterior walls. Balconies count only when built as heated, year-round rooms. A high-rise unit may be measured on a middle floor, and every stated area must carry the note that actual usable floor space may vary. The figure may be off by up to 2%.
- Listings in Alberta must use the Real Estate Council of Alberta's Residential Measurement Standard. An apartment-style condo is measured inside, paint to paint, at floor level; detached houses and townhouses at the exterior wall at the foundation. Levels partly below grade are left out, and the space must have a floor-to-ceiling height of at least 2.13 m (7 ft). The figure must be within 2%.
- Statistics Canada uses above-grade living area, which leaves out basements.
- Square feet and square metres. Listings and builders mostly quote square feet; the codes use square metres. 1 m² is about 10.76 sq ft.
So the same condo can carry two different sizes: measured the Ontario new-build way, part of its walls are included; measured paint to paint, the Alberta way, they are not.
Common mistakes
- Taking Ontario's numbers as Canada's. The national code sets no room areas; your province and city decide.
- Counting the closet. Ontario's bedroom minimums leave out closets and built-in cabinets.
- Comparing square footage between listings measured in different ways.
- Counting the floor under a sloped ceiling. Under 1.4 m (4 ft 7 in) of headroom it does not count toward a bedroom's area in Ontario or Toronto.
- Judging a room by its area, not its shape. A room of 2.73 × 2.53 m (6.9 m²) just fits a queen with snug walkways; a long, narrow room of the same area does not.
Check it in 3D
In Flatwalk you upload your floor plan as a photo, a screenshot or a PDF, draw it yourself, or scan a room by tapping its corners through the camera. On a plan with no sizes, tap a wall you know and type its real length; fix any wall the plan reader got wrong the same way. Then place real furniture from real stores at its true size and walk through at eye level. A tape measure lives in the 3D home: tap both sides of a gap and read it, in metres or in feet and inches.
What it does not do: your plan is only as true as the sizes you give it, and Flatwalk does not tell you what the rules in your province or city require. Measure the real room with a tape measure.
Also for Canada: bed sizes and door widths.

Questions people ask
What is the minimum bedroom size in Canada? There is no national one: the National Building Code sets no room areas. Ontario's Building Code asks for at least one bedroom of 9.8 m² (105 sq ft), or 8.8 m² with built-in cabinets, and 7 m² (75 sq ft) for other bedrooms, or 6 m² with built-in cabinets. Cities such as Toronto and Brampton set their own rules for rooms people sleep in.
What is the minimum bedroom size for a queen bed? A queen is 60 × 80 in (152.5 × 203 cm). With 60 cm (2 ft) on both sides and 50 cm (20 in) at the foot, the bed and its walkways need about 2.73 × 2.53 m (8 ft 11 in × 8 ft 4 in); with 80 cm on both sides and 70 cm at the foot, about 3.13 × 2.73 m (10 ft 3 in × 8 ft 11 in). A dresser and the door swing need more on top.
How big must a master bedroom be in Ontario? At least one bedroom in every home must have 9.8 m² (105 sq ft) of floor, or 8.8 m² (95 sq ft) where built-in cabinets are provided, not counting the closet (2024 Building Code, Article 9.5.3D.2).
What is the minimum ceiling height for a room in Canada? The national code, as BC adopted it, asks for 2.1 m (6 ft 11 in) over the room or a set part of it. Ontario asks for 2.3 m (7 ft 7 in) over at least three quarters of the required area in living rooms, dining areas and kitchens, and in bedrooms 2.3 m over half of it or 2.1 m over all of it.
How is square footage measured in Canada? It depends on who measures. Ontario builders measure a condo to the centre of the shared walls and the outside of the corridor wall; Alberta listings measure a condo inside, paint to paint. Ask how a figure was measured before you compare two homes.
