Introduction

Quick Note on Names (Because Yes, They're Confusing)
Let’s clear something up right off the bat: mattress names don’t always make sense.
Twin is also called a Single
Double = Full
King in Canada is usually what Americans call Eastern King
And Split King isn’t really a size — it’s two Twin XLs side-by-side
| Common Name | Also Known As |
|---|---|
| Twin | Single |
| Double | Full |
| King (Canada) | Eastern King |
| California King | Cal King |
| Split King | Two Twin XLs |
These naming quirks are one reason so many people struggle to understand mattress sizes in Canada , especially when shopping online or comparing options. Lets move on...
Mattress Sizes in Canada Chart
🧠 How to read this :
To make sense of mattress sizes in Canada , it helps to look at the actual dimensions side-by-side. Width matters most for comfort with a partner (or dog), and length is key for tall sleepers. Everything is listed in both inches and centimetres so you can measure your space easily.
| Size | Inches (W x L) | CM (W x L) |
|---|---|---|
| Twin / Single | 38" x 75" | 96.5 x 190.5 cm |
| Twin XL | 38" x 80" | 96.5 x 203 cm |
| Double / Full | 53" x 75" | 134.5 x 190.5 cm |
| Queen | 60" x 80" | 152.5 x 203 cm |
| King (Eastern) | 76" x 80" | 193 x 203 cm |
| California King | 72" x 84" | 183 x 213 cm |
| Split King | Two Twin XLs | 2 x 96.5 x 203 cm |
Keep in mind, mattress sizes in Canada may differ from U.S. or European standards, so always double-check your frames and protectors before ordering online.

California King vs Eastern King — Which One’s Bigger?
This is probably the most common mix-up we see at the store. People hear “California King” and assume it must be the biggest bed you can get. But here's the truth:
Eastern King (also just called “King” in Canada) is wider
California King is longer
So if you’re trying to sprawl out with your partner, a toddler, and a dog — Eastern King gives you more side-to-side room. If you're over 6'3", and don’t mind a narrower sleep surface, California King gives you a bit of extra legroom.
Here’s what we tell customers:
Eastern King Pros:
The widest mattress you can buy — amazing for couples or families
Easy to find bedding, protectors, and bed frames in Canada
Fits most master bedrooms comfortably
Eastern King Cons:
It’s a bit shorter — might not be ideal for super tall folks
California King Pros:
Great if you’re very tall and want those extra four inches of length
Nice fit for long, narrow rooms or custom design layouts
California King Cons:
Harder to find sheets, protectors, and frames in Canada
Feels tighter side-to-side — not great for bed-sharing with kids or pets
Usually special order only at Canadian retailers (including us)
💡 Our Honest Advice
Unless you’re unusually tall or building a very specific designer bedroom, we almost always recommend the Eastern King . It’s more comfortable, more practical, and easier to shop for across Canada.
How to Choose the Right Mattress Size (Real Advice from Our Store)
-
We’ve helped thousands of people pick the perfect size. Here’s what we’ve learned:
👩❤️👨 For Couples
Queen is the sweet spot for most — enough room to sleep comfortably, fits most bedrooms.
King is ideal if you’ve got the space (and kids or pets crawling in).
- 🏙️ Small Spaces (Condos, Basements, or Older Homes)
Double or Queen are best.
Always measure stairwells and tight turns — King mattresses don’t bend .
- 🧒 Growing Kids & Teens
Go with a Twin XL — gives them extra length without the width of a Double.
- 🐾 Pets or Kids in Bed
King is the move. Or be prepared to sleep on the edge every night.
- 🚚 Move Often?
Queen is the safest choice — easier to move, still comfy.
Kings are heavy and awkward. You’ll feel it on moving day.
Common Mattress Size Mistakes (And How to Avoid Them)
Thinking a Full is bigger than a Queen — it's not. It’s shorter and narrower.
Buying a Cali King in Canada — then struggling to find sheets or a protector.
Measuring your room, but forgetting to check stairwells and hallways .
Buying a bed so big it turns your bedroom into a wall-to-wall mattress.
“Most people think mattress sizes are universal — until they show up with sheets that don’t fit. We’re here to make sure that doesn’t happen.”
. 🧠 Mattress Sizes in Canada – FAQ
1. What’s the difference between a Double and a Full?
Nothing! A Double and a Full are exactly the same size: 53” x 75”. The two terms are used interchangeably — it just depends where you’re shopping or who you’re talking to.
2. Is a Twin the same as a Single?
Yes — in Canada, a Twin and a Single are the same thing. It’s just a naming difference. Both measure 38” x 75”.
3. What’s the biggest mattress size in Canada?
The Eastern King (76” x 80”) is the widest standard mattress you can easily find in Canada. A California King is longer, but narrower — and much harder to shop for here.
4. Should I get a California King or an Eastern King?
We usually recommend the Eastern King unless you're over 6'3" or designing for a very long, narrow space. California Kings are harder to find bedding for in Canada and often have to be special ordered.
5. What’s a Split King?
A Split King is just two Twin XL mattresses side by side. This setup is popular with adjustable bases so each side can move independently.
6. Can I use U.S. mattress sizes in Canada?
Technically yes, but sizes and terminology can differ slightly — especially with frames, protectors, and sheets. We recommend buying Canadian-standard sizes to avoid mismatches.
✅ Mattress Sizes in Canada – Quick Summary
Twin = Single (38” x 75”) – Best for kids or tight spaces
Twin XL (38” x 80”) – Great for teens or tall solo sleepers
Double = Full (53” x 75”) – Good for one adult, tight for two
Queen (60” x 80”) – Ideal for most couples, most common size
King (Eastern) (76” x 80”) – Widest option, great for couples, pets, or co-sleeping
California King (72” x 84”) – Longer but narrower; great for tall people, less ideal for families
🧠 Pro Tips:
Eastern King is wider ; California King is longer but harder to find accessories for in Canada
Always measure your room + stairwells before buying
Leave 30 inches of space around the bed for comfortable movement
Don’t let the names confuse you — Double = Full, Twin = Single
