Bed Sizes in Feet: Complete Canadian Chart with Room Requirements

Reading Time: 13 minutes

You are standing in your bedroom with a tape measure in one hand and a browser open on your phone in the other. You need to know bed sizes in feet because the mattress tag just says "Queen" and you have absolutely no idea whether that will leave you enough room to open the closet door. You are not alone. We get this question at Mattress Miracle in Brantford almost every single week, and the answer is both simpler and more interesting than most people expect.

Canadian beds follow a standard sizing system that goes back decades, but the measurements are not always advertised in feet. Most tags show centimetres. Most American websites show inches. What you actually need, when you are standing in your bedroom with that tape measure, is feet. So here is everything, in one place, with the room recommendations included.

Complete Bed Sizes Chart: Feet and Metric

The table below covers every standard size you will find at a Canadian mattress retailer, plus the room minimums we recommend after 38 years of helping Brantford families fit beds into their homes. We have included both feet and centimetres because you will likely need both: feet to picture the room, centimetres when you get to the store or read the product tag.

A quick note on the Split King: it is the same footprint as a standard King but consists of two Twin XL mattresses side by side. It is the size you need if you want an adjustable base that lets each partner control their own head and foot position independently. Dorothy on our team calls it the "best thing to happen to couples since the remote control."

Twin and Twin XL: Smaller Than You Think

The Twin is Canada's smallest standard mattress at 3.17 feet wide and 6.25 feet long. That is about the width of a single person lying flat, with perhaps six inches of room on either side if you are average build. It works beautifully for children's rooms, bunk beds, and tight guest rooms. It is not particularly comfortable for two adults to share, even briefly.

The Twin XL adds exactly five inches of length, bringing it to 6.67 feet. That extra length matters a great deal if the person sleeping in the bed is tall. A six-foot sleeper on a standard Twin has about three inches between their feet and the bottom of the mattress. On a Twin XL, they have eight inches. That is the difference between sleeping comfortably and waking up with cold feet hanging off the edge.

Twin and Twin XL mattresses are also the sizes used in most Canadian college and university dormitories, which is worth knowing if you are buying for a student. Check the specific school's specifications before purchasing, as some older residence buildings still use narrower, non-standard frames.

Double/Full: The Most Misunderstood Size in Canada

Here is where things get interesting, and where a lot of Canadians waste money buying the wrong sheets. In Canada, "Double" and "Full" refer to the exact same mattress: 4.5 feet wide by 6.25 feet long (137 x 190.5 cm). The names are completely interchangeable. Some retailers use one, some use the other, and some use both together as "Double/Full." They are the same bed.

This size was designed for two people, which is probably why it got the name "Double." In practice, two adults sharing a Double have about 27 inches of width each. For reference, a standard cot is 27 inches wide. It can be done, but it is cosy in a way that not everyone appreciates. For a couple who wants genuine comfort, the Queen is usually the honest answer. Our full comparison of Twin vs Double vs Queen goes into the real-world differences in more detail.

The Double is, however, an excellent size for a solo adult who wants more room than a Twin without committing to a Queen-sized bed frame and all the space that requires. It fits well in older Brantford homes where the second bedroom was built in an era when bedrooms were smaller and people apparently had fewer possessions.

Queen Size: Why It Became Canada's Favourite

The Queen is 5 feet wide and 6.67 feet long (152.5 x 203.5 cm). It gives each person in a couple about 30 inches of personal width, which is meaningfully more than the Double's 27 inches per person. That three-inch difference sounds small in a hardware store, but at 2 a.m. when your partner rolls over, those three inches feel like a garden.

The Queen became Canada's most popular mattress size because it hits the right balance for most households: large enough for two adults to sleep comfortably, small enough to fit in most master bedrooms without requiring a room renovation. At 5 feet wide, a Queen needs at least 10 feet of room width to allow for nightstands and walkable space on each side. Most Canadian master bedrooms from the 1980s onward meet that requirement.

If you are shopping for a Queen right now, one of our top-selling options is the Restonic ComfortCare Queen with 1,222 individually wrapped coils. It is priced at $1,125 and the coil count means you get genuine motion isolation between partners. You can see it in person at our Brantford showroom or browse our full mattress collection online.

The Queen also has the widest selection of frames, headboards, and bedding available in Canada, which is a practical advantage. If you are someone who likes to change up your bedroom aesthetic every few years, the Queen gives you the most options at the widest range of price points.

King and California King: When You Need the Extra Room

The standard King, sometimes called the Eastern King to distinguish it from the California King, is 6.33 feet wide and 6.67 feet long (193 x 203.5 cm). It is the widest mainstream mattress size available in Canada. Each person in a couple gets about 38 inches of width, which is as much space as an individual Twin mattress. Some parents describe it as the only thing that made co-sleeping with a toddler actually work. Some dog owners describe it the same way.

The California King narrows slightly to 6 feet wide but extends to 7 feet long (183 x 213.5 cm). This trade is worth making if one or both partners are significantly taller than average. At 7 feet long, even a six-foot-four person has comfortable clearance. The narrower width is a real consideration for couples who are not tall, though. A standard King gives each person 38 inches; a California King gives each person 36 inches. Worth checking your height before defaulting to the longer option.

Both King sizes require meaningful room space. You need a minimum of 12 feet of room width to fit a King or California King with adequate walking space on each side. If your bedroom is 11 feet wide, you will be sliding around the end of the bed to get to the closet, which gets old quickly. Measure twice before you commit to this size.

Room Size Requirements for Every Bed Size

Having the right bed size in feet is only half the equation. The room has to work around it. The numbers below assume you want nightstands on both sides of the bed (about 18 to 24 inches each), a clear walkway of at least 24 inches at the foot of the bed, and a clear path to the closet or door. These are real livability numbers, not theoretical minimums.

One thing the table does not capture is door placement. A bedroom with the door on the side wall has different constraints than one with the door at the foot of the bed. We always encourage customers to sketch their room on paper before coming in, marking where the door, windows, and closet are located. It takes five minutes and saves significant frustration later.

How to Measure Your Bedroom for a New Mattress

Measuring a bedroom properly takes about ten minutes and requires only a tape measure and something to write with. Here is the process we walk customers through when they call the store.

A practical example: your bedroom is 11 feet wide and 12 feet long. Subtract 2 feet on the left side for a walkway, and 2 feet on the right for a nightstand plus walkway. That leaves 7 feet of usable width, which means a King (6.33 ft wide) fits with a bit of breathing room. In the other direction, subtract 2 feet for foot-of-bed clearance, leaving 10 feet of usable length. A King at 6.67 feet long fits easily. A California King at 7 feet long fits with 3 feet at the foot, which is comfortable. Both sizes work in this example room, which means the decision comes down to personal preference and whether either partner is taller than average.

If you want help working through your specific room dimensions, call us at (519) 770-0001. Brad or Dorothy can walk you through it in a few minutes, or you can bring your measurements to our showroom at 441 1/2 West Street in Brantford and Talia will set up some reference tape on the showroom floor to help you visualise the actual footprint.

Canadian vs American Sizing: What You Need to Know

Canadian and American mattress sizes use the same dimensions for most sizes, which is convenient. The main differences come down to naming and a few regional quirks worth knowing before you order anything online from an American retailer.

The dimension that catches Canadians off guard most often is the California King versus the standard King in terms of which is bigger. Many people assume the California King is larger in every direction because the name suggests something grand and oversized. It is actually narrower than a standard King. It is only longer. The standard King is wider. If you are buying a King-sized comforter for a California King, it will not fit properly, and if you are buying a California King bed frame for a standard King mattress, it will also not fit. These are the kinds of details that cost people money.

For a deeper look at how sizes compare and which order they fall in from smallest to largest, our article on bed size order in Canada covers the full sequence with practical guidance on choosing between adjacent sizes.

Converting Between Feet, Inches, and Centimetres

Since Canadian product tags almost always show centimetres, and most of us picture space in feet, here is the quick conversion reference you will use repeatedly.

If you find yourself doing this calculation in a store aisle, the fastest shorthand is this: take the centimetre measurement, divide by 30, and you have an approximate foot measurement. A 152.5 cm Queen width divided by 30 is roughly 5.1 feet, which is close enough for planning purposes. For exact figures, use the 0.0328 multiplier or simply reference the chart at the top of this article.

Mattress Depth: The Measurement Everyone Forgets

Width and length get all the attention, but mattress depth (sometimes called height or profile) matters for practical reasons that show up on day one of living with your new bed. Modern mattresses range from about 8 inches (20 cm) for basic foam mattresses to 15 or even 18 inches (38 to 46 cm) for pillow-top and hybrid models with generous comfort layers.

Depth affects three things directly: how your fitted sheets fit (standard sheets are designed for mattresses up to 14 inches deep; anything thicker needs deep-pocket sheets), how easy it is to get in and out of bed (important if either partner has mobility considerations), and whether your existing bed frame includes a box spring gap that will look odd if the mattress is much thinner or thicker than the original.

Choosing the Right Size: A Practical Framework

All the charts and measurements in the world still leave some people uncertain about which size to actually buy. Here is the framework we use at Mattress Miracle when a customer comes in genuinely undecided.

We do not push customers toward larger mattresses because larger mattresses cost more. We push customers toward the right mattress for their actual life, because a customer who is happy in their bed is a customer who sends their neighbour to us five years later. That has been Brad's philosophy since 1987 and it has not changed.

Special Sizes: Cot, RV, and Alaskan King

Standard retail sizing covers the sizes above, but a few special cases come up regularly enough to mention.

RV Mattresses: Recreational vehicles use non-standard mattress sizes because the sleeping spaces are built to fit the vehicle, not the other way around. Common RV sizes include Short Queen (60 x 74 in rather than 60 x 80 in), RV King (72 x 80 in), and Three-Quarter (48 x 75 in). These require specialist suppliers and are not stocked at most retail mattress stores.

Alaskan King: The Alaskan King is a non-standard luxury size at 9 feet by 9 feet (108 x 108 in or 274 x 274 cm). It is made by specialty manufacturers and requires a custom bed frame and custom bedding. It is real, it exists, and it is exactly as excessive as it sounds. Most Brantford bedrooms cannot accommodate it.

Wyoming King: Another non-standard luxury size at 7 feet by 7 feet (84 x 84 in or 213 x 213 cm). Also requires custom frames and bedding. Worth knowing exists; not worth planning around unless you have a very specific situation and a very large budget.
