Are Canadian and US mattress sizes the same?

Yes, the labels align across both markets, so a Canadian bed size chart matches its American counterpart size for size. Listed dimensions can still differ slightly from maker to maker, though. Always confirm the exact specs on the product page.

Is a Double bed the same as a Full bed in Canada?

Yes, they're two names for one size, and that's why any mattress sizing chart lists them together. Check the listed dimensions anyway, since individual products can vary by a centimetre or two.

What is the difference between a King and California King?

A King measures 76 x 80 inches, a California King 72 x 84. Neither is larger overall: the difference is a straight trade, four inches of width for four inches of length.

Should a bed frame be the same size as the mattress?

The named size must match, so a Queen mattress needs a Queen frame. Beyond that, compare the listed bed dimensions on both products, since bed frames vary slightly, and confirm the frame provides the support system the mattress warranty requires.

Does mattress thickness change the bed size?

No. Thickness changes the height of the bed, while the width-and-length footprint stays standard. The one practical effect: deep mattresses may need deep-pocket sheets.

Bed Size Chart Canada: Mattress Sizes and Dimensions

Brick Team // 7 oct. 2026

Canada uses 6 standard mattress sizes: Twin/Single, Twin XL, Double/Full, Queen, King and California King. The double names are the first thing that trips people up: Canadian mattress sizes often carry two labels for the same dimensions. The bed size chart below sorts all of this out.

Canadian Mattress Size Chart in Inches and Centimetres

Here's the bed size chart in cm and inches side by side, so you can compare standard sizes against your room measurements in whichever unit your tape uses.

Common Name	Alternate Name	Width x Length (in)	Width x Length (cm)	Best suited for
Twin	Single	38 x 75	96.5 x 190.5	Kids and solo sleepers in small rooms
Twin XL	-	38 x 80	96.5 x 203	Taller solo sleepers
Double	Full	54 x 75	137 x 190.5	Solo adults who want width
Queen	-	60 x 80	152.5 x 203	Couples
King	-	76 x 80	193 x 203	Couples who want maximum width
California King	Western King	72 x 84	183 x 213.5	Taller couples

Exact dimensions can vary by a centimetre or two between manufacturers, so always confirm the listed measurements on the product page. Once you know your size, you can shop mattresses by size and compare models directly.

What Each Standard Bed Size Is Best For

Two numbers settle most of this decision. Width decides how many people sleep comfortably, and length decides whether tall sleepers fit. Everything below is those two numbers applied to real rooms and real people. Here's each of the six Canadian sizes in detail:

Twin and Twin XL

Twin is the smallest standard size on any bed sizes chart. In Canada it usually goes by its local name, the Single bed. It fits kids' rooms and other tight spaces, and it's what bunk beds are built around. Twin XL keeps the same width and adds five inches of length. That extra length is why dorms use it: a tall sleeper fits, and the footprint stays small.

Double or Full

Double and Full are one size with two names, which is why a mattress sizes chart lists them in a single row. Compared with a Twin, a Double adds sixteen inches of width, and for a solo sleeper that's the difference between fitting in the bed and spreading out in it. The length stays at 75 inches. Sleepers approaching six feet should take that number seriously before buying.

Queen

A Queen adds width and length over a Double, and that's the point where a bed stops being generous for one and becomes comfortable for two. Couples treat it as the default for a reason. On any bed size comparison chart, the Queen sits in the middle, so it's the natural reference point: step down if the room is tight, step up if you both want more space.

King and California King

A King gives two sleepers sixteen more inches of width than a Queen, enough to stop negotiating territory at night. California King is a different trade, four inches narrower and four inches longer , so neither wins outright. Pick by what runs out first in your bed: elbow room or legroom. A split King, two Twin XLs side by side, suits couples who want an adjustable base with separate settings. RV and custom sizes follow their own measurements and sit outside standard charts entirely.

How to Choose the Right Bed Size

Before picking the right size from our bed sizing chart, work through these four checks:

Count the sleepers.

Include pets if they share the bed; a large dog claims as much width as a small adult.

Check sleeper height and preferred space.

Anyone over 6 feet should look at 80-inch lengths or longer.

Measure the room.

Keep roughly 60 cm of walking clearance around the bed, because room size limits your options faster than budget does.

Check the delivery path.

Doorways, stairs and hallways all matter, as does clearance for a matching bed frame and the rest of your furniture.

Before you commit, tape the mattress footprint on the floor. Seeing the real rectangle inside your room dimensions beats imagining it every time.

Match Your Mattress, Bed Frame and Foundation

Labels alone aren't enough. Two products both marked "Queen" can differ by a couple of centimetres , so compare the listed width and length on the mattress and on the frame before you buy. A size chart tells you what a Queen should measure; the product page tells you what this Queen actually measures.

The foundation needs the same check. Mattress warranties often specify the support type, whether that's a box spring, a platform, or an adjustable base. You'll find box springs and mattress bases listed with their exact dimensions and supported mattress types, so matching them takes a minute.

One last clarification: thickness changes bed height, never the footprint. Your fitted sheets care about thickness; your frame cares about footprint.

Final Bed Size Checklist

Run through these five checks before you order:

Exact dimensions confirmed on the product page
Room clearance measured, tape on the floor
Frame size matched to the listed numbers
Foundation compatibility checked against the warranty
Delivery path clear from the door to the bedroom

That's the whole bed size chart put to work. When you've settled on a size, browse the mattresses in that dimension and compare from there.
