No. Mattress sizes vary by country. Canada shares sizing with the U.S. (e.g., Queen is 80″ x 60”), but international equivalents differ (e.g., a UK King is closer to a North American Queen).

Choosing the right mattress size can make a big difference in how well you sleep and how comfortably your mattress fits into your space. Whether you’re furnishing a guest room, upgrading to a bigger bed, or just curious about what mattress sizes are available in Canada, this guide will help you understand your options.
In Canada, mattress sizes generally follow North American standards. That means familiar names like twin, double, queen, and king, but the dimensions can still vary slightly from international equivalents. Understanding these mattress dimensions can help you decide what works best for your sleep style, body size, room layout, and budget.
From single and double mattress sizes to queen and king sizes, we’ll walk you through everything you need to know about mattress dimensions in Canada, including a handy size chart that shows which mattress is best suited for whom, and how to choose the right one for your needs.
We’ll also help answer some of the most common questions, like:
This guide covers all standard Canadian bed sizes, from crib to California king, with key dimensions in inches and centimetres. It also includes custom and RV sizes, international equivalents, and helpful tips based on room size, number of sleepers, and budget.
Mattress Size | Dimensions (inches) L x W | Dimensions (cm) L x W | Also Called (International) |
|---|---|---|---|
Crib | 52″ x 28″ | 132 x 71 cm | Cot (UK), Baby Mattress |
Twin | 75″ x 38″ | 190.5 x 96.5 cm | Single (UK, AU) |
Double (Full) | 75″ x 53″ | 190.5 x 134.5 cm | Full (US), Double (CA/UK) |
Queen | 80″ x 60″ | 203 x 152.5 cm | Queen (US/UK/AU) |
King | 80″ x 76″ | 203 x 193 cm | Eastern King (US), King (UK/AU) |
California King | 84″ x 72″ | 213.5 x 183 cm | Western King (US) |
RV Bunk | 75″ x 28″ | 190.5 x 71 cm | Camper Bunk, Truck Bed, etc. |
RV Three-Quarter | 75″ x 48″ | 190.5 x 122 cm | — |
RV Short Queen | 75″ x 60″ | 190.5 x 152.5 cm | RV Queen |
Your ideal mattress size depends on more than just who’s sleeping on it. Consider the following:
We’ll expand on each of these topics in the section below.
Crib Mattress Dimensions: 52″ L x 28″ W (132 cm x 71 cm)
Crib mattresses are specially designed to fit snugly inside standard cribs, providing a safe and supportive sleep surface for infants and toddlers. In Canada, crib mattress dimensions follow North American safety standards, which are tightly regulated for fit and firmness.
Designed for the little ones, they’re the smallest mattress size available at just 52″ by 28″ (132 x 71 cm). In Canada, they’re always 6″ high to meet federal regulations for safe sleep. They tend to be much firmer than adult mattresses because a firm surface is generally considered safer for babies.
A crib mattress should fit securely in the crib frame with no more than two fingers of space between the mattress and crib sides. This helps prevent entrapment and promotes safer sleep.
FAQ: Can I use a crib mattress in a toddler bed?
Yes. Many toddler beds are designed to fit standard crib mattresses. If you’re transitioning your child out of a crib, keeping the same mattress can save money and maintain a familiar sleep surface.
Twin Mattress Dimensions: 75″ L x 38″ W (190.5 cm x 96.5 cm)
A twin mattress is the smallest standard adult mattress size in Canada. It’s a popular choice for kids, bunk beds, and smaller guest rooms. It is a great option for budget-conscious shoppers or people with small bedrooms or shared spaces.
International Equivalents:
FAQ: Is there a mattress size smaller than twin?
Yes. Crib mattresses and some RV bunks are smaller than a twin. These are typically not used past early childhood. Twin/single is the smallest commonly available size for adults.
Twin XL Mattress Dimensions: 80″ L x 38″ W (203 cm x 96.5 cm)
If you find a regular twin bed a bit short for your liking, the twin XL is the perfect solution. It is the same width as a twin but five inches longer. As such, it’s suitable for taller people who need more legroom or space to stretch out. This versatile mattress fits well in a child’s bedroom or a dorm room.
Twin XL offers an extra 5 inches of legroom compared to a regular twin making it a great choice for or taller teens, college students, or compact guest rooms. Two twin XL mattresses placed side-by-side equal the dimensions of a king-sized bed. This makes them perfect for adjustable bases, allowing you to create a split-king setup and control each side of the bed independently.
Online brands like Juno offer a twin XL mattress size for under $450.
International Equivalents:
FAQ: Can I use regular twin sheets on a twin XL mattress?
Not comfortably. Twin XL mattresses require specially sized sheets due to the added length.
Double/Full Mattress Dimensions: 75″ L x 53″ W (190.5 cm x 134.5 cm)
A double mattress (also known as a full) is wider than a twin and can sleep one adult comfortably. This mattress size provides significantly more sleep surface than the twin or twin XL. As such, it is ideal for single adults who need a bit more sleep space. It’s also useful for individuals or couples with limited bedroom space or smaller living quarters. A double mattress will also fit in most guest rooms and dorm rooms.
If you have a young child, it may be more budget-friendly to bypass a twin and go straight to a double following their “crib years.” Since they will inevitably outgrow a twin, this helps you avoid the hassle of buying two mattresses within a brief timespan.
Do you tend to toss and turn in bed? Have a partner or pet who loves sleeping next to you? A double may be a good option. However, if you plan on sharing your bed with a significant other and a furry friend, sleeping arrangements may feel a bit snug.
Do you need extra legroom for a taller person? You can purchase a double XL where this size is available. It measures 80″L x 53″ W (203 x 134.5 cm), five inches longer than a typical double mattress size.
International Equivalents:
FAQ: Is a double mattress big enough for two people?
Technically yes, but space is tight. A double only offers 26.5″ (67 cm) of width per person (less than a crib mattress). For better comfort, we recommend couples or people sharing a bed consider a queen mattress.
FAQ: What’s the difference between a full and a double mattress?
A double is the same as a full mattress. They’re just two different names for the same mattress. Your full-sized sheets will fit your double mattress without any trouble, and vice versa.
Queen Mattress Dimensions: 80″ L x 60″ W (203 cm x 152.5 cm)
A crowd favourite, the queen mattress size is one of the most popular choices. At 4,800 square inches, it offers an ideal combination of space, comfort, and affordability. Plus, it’s the most affordable option among the “big” mattresses and queen-sized bedding accessories are often easy to find.
With a queen, you get plenty of sleeping space without feeling too big and bulky. As such, it strikes the perfect balance between providing enough room to stretch out comfortably while still fitting into most bedrooms. It’s ideal for most couples and primary bedrooms.
Despite its compact design, the queen provides enough room for two adults to sleep side-by-side without feeling cramped. It does get a little cramped when kids or pets climb in, so keep that in mind.
Shopping for a good queen size mattress? Consider Douglas, this year’s top pick for Canadian sleepers at just $799 for a queen, or check out our list of the best mattresses.
International Equivalents:
FAQ: Is a queen mattress good for couples?
Yes. It’s generally considered the minimum comfortable size for two adults, offering 30″ (76 cm) of space per person.
King Mattress Dimensions: 80″ L x 76″ W (203 cm x 193 cm)
With over 6,000 square inches of sleep space, the king is Canada’s largest standard bed size. Two adults can easily get their own sleeping space, allowing for maximum freedom of movement. Plus, if you have a pet or child who occasionally joins you, the king offers enough room for everyone to snuggle up.
If you have a master bedroom, the king size fits perfectly while enhancing the overall aesthetic. This size of mattress is often seen as a luxury. However, it’s possible to get a king-size foam mattress for under $1,000 when you buy one of Canada’s best king-size mattresses from accessibly priced quality brands like Douglas.
If you would prefer a hybrid mattress (a mattress with foam and spring combination), then we recommend the Logan & Cove Choice, a luxury hybrid mattress for less than $1000.
While the king is generally made for more than one sleeper, single adult sleepers may also enjoy the generous dimensions of this mattress size.
If you and your partner are looking for a king-size bed but have different mattress preferences, consider buying two twin XL mattresses. Placing two twin XL mattresses side-by-side equals the same total area of a king. This is known as a split king mattress and works well with two-sided adjustable beds.
A split king is a great option if you need a softer (or firmer) mattress than your partner, or if one of you prefers to sleep at an angle. To get the best use out of it, pair it with a split bed base like Douglas’s adjustable bed.
International Equivalents:
FAQ: What’s the difference between a king and a California king?
A standard king is wider and shorter. A California king is narrower but longer — better for tall people or narrow rooms.
California King Mattress Dimensions: 84″ L x 72″ W (213 cm x 183 cm)
The California king is specifically designed for tall people. With four additional inches of legroom, this size provides the necessary length to ensure your feet won’t hang off the end of the bed. This mattress is less common in Canada but ideal for those needing extra legroom.
Note that California king mattress offers slightly less sleep surface than a regular King-sized mattress. While it is four inches longer than a regular king mattress, it is also four inches narrower.
The Cal king size mattress is also well-suited for narrow bedrooms. Because of its slimmer profile, it may fit more seamlessly into rooms with limited space. Popular in the U.S., they’re less common in Canada and may require special-order sheets or bed frames. They can also sometimes be more expensive.
International Equivalents:
FAQ: Is a California king bigger than a standard king?
Not quite. It’s longer but also narrower. Choose a Cal king if legroom matters more; stick with a standard king for more elbow room.
If you’re outfitting a camper, trailer, or motorhome, you may have noticed that standard mattress sizes don’t always fit. That’s because RV mattress sizes in Canada are different from residential mattresses. They are often shorter, narrower, or completely custom. Common RV mattress measures 75″ long (190.5 cm), but width can vary depending on the size of the bed frame. There are three common RV mattress sizes:
Note: Sizes vary by RV brand and model. Always measure your sleep platform before purchasing a replacement mattress. If you can’t find an exact fit, many Canadian mattress manufacturers offer custom RV mattress options.
Mattresses like Douglas and Juno come in all three standard RV sizes.
FAQ: Can I use a regular mattress in my RV?
It depends. If your RV can accommodate the full dimensions of a standard mattress and support the weight, then yes. But in many cases, a standard queen or king will be too long or wide for built-in RV platforms. You’ll likely need a mattress that’s no more than 75″ long, and narrower than your mattress at home. Measure your RV’s bed frame and compare with our size chart to see what size it can accommodate. Many RV mattresses have shorter lengths to save space and often use lighter materials (like foam) in their composition to reduce overall vehicle weight.
Whether you’re outfitting an RV, a vintage bed frame, or a large family sleeping space, custom and non-standard mattresses can meet unique needs.
Examples of custom mattress sizes:
Custom Size | Dimensions (inches) | Use Case |
|---|---|---|
Small Single | 75″ L x 30″ W | RV bunks, tight child beds |
Small Double | 75″ L x 48″ W | Older bed frames |
Double (Full) XL | 80″ L x 53″ W | Taller single sleepers |
Olympic Queen | 80″ L x 66″ W | Couples wanting more space |
Super King (UK) | 78″ L x 72″ W | Luxury suites |
RV Short King | 75″ L x 72″ W | Campers, RVs |
Alaska King | 108″ L × 108″ W | Co-sleeping families, giant bedrooms |
FAQ: Do custom-size mattresses cost more than standard ones?
Usually, yes. Custom sizes are often made-to-order, with higher prices and limited accessory availability.
Mattress size isn’t just about how many people will be sleeping on it. Your lifestyle, living space, and even how often you move can all influence the best choice. Here’s how to think through your options:

Before choosing a size, measure your room. Every room needs space to move freely. A good rule of thumb is to allow at least 24–30 inches of clearance (about two to three steps) around the sides and foot of the bed for easy movement and for furniture. Smaller rooms (under 100 sq. ft.) may be better suited to a twin or double, while larger primary bedrooms can easily fit a queen or king. See table below to help give an idea minimum room size for each mattress.
Mattress Size | Minimum Room Size |
|---|---|
Twin / Single | 7′ x 10′ |
Double | 9′ x 10′ |
Queen | 10′ x 10′ |
King | 12′ x 10′ |
California King | 12′ x 12′ |
Tip: In tight spaces, a double or queen is usually more practical than a king, especially if you want room to move around the bed.
Bigger mattresses usually cost more, not just for the bed itself, but also for the frame, bedding, and accessories.
When it comes to mattresses, bigger often means pricier. That’s because larger sizes require more materials for construction. If your budget is tight and your heart is set on a bigger mattress, consider going the mattress-in-a-box route. Online retailers such as Juno offer mattresses at much lower prices than comparable mattresses.
If you’re on a budget, a king-size mattress can still be obtained for less than $600. You can still get great comfort without the premium price tag. If you’re furnishing a guest room or starter home, a twin, double, or queen might be a more affordable option. But if comfort is a top priority, investing in a larger size could be worth it in the long run.

Selecting the right mattress size isn’t always just about your sleeping preferences, it’s also about the sleeping preferences of your loved ones. Don’t forget to consider the number of people and pets sharing your bed either.
A single or twin mattress is ideal for one person, especially a child or teen. But if you’re sleeping with a partner (or sharing your bed with a pet or child), a queen or king mattress will provide more personal space and better sleep quality.
Your ideal mattress should offer ample room for everyone, ensuring a peaceful sleep without feeling cramped or squeezed. If you’re sharing a bed, consider one with great motion isolation like Douglas, so you don’t feel your partner or pets moving around at night.

Are you a sprawler or a cuddler? Do you stay in one position all night or find yourself frequently changing positions? And what of your sleep partner? If one or both of you like having the freedom to move around, a king or California king could be a game-changer. But if you revel in the intimacy of the person next to you, a queen might be more ideal.
Finding the perfect bed size for your body means waking up refreshed and ready to conquer the day. That means taking your size and height into account.
Taller individuals (around 6 feet or more) tend to feel cramped on mattresses shorter than 80 inches and will find a twin XL or California king size more suitable for their frame. In contrast, heavier-set individuals may prefer a queen or king size for added width.
A good rule of thumb: Your mattress should be at least 6 inches longer than your height for optimal comfort.

First, consider where the mattress will be going. Is it on a higher floor of your home? Will you need to navigate it through narrow staircases and door frames? These hurdles can turn into roadblocks, especially for larger beds. So, take a moment to visualize the journey and assess any potential obstacles before deciding.
Meanwhile, weight matters too! Some mattresses can be quite heavy. Consider if you have the muscle power to move it yourself or need some helping hands.
If you move frequently or live in an apartment with tight stairwells, a larger mattress could be tricky. Queen and king sizes are heavier and harder to maneuver, especially traditional innerspring models. Some online mattresses come compressed in boxes, which makes delivery and setup easier. But once unpacked, they’re not easily compressed again. For great options of this type of mattress, check out our list of best mattresses-in-a-box.
No. Mattress sizes vary by country. Canada shares sizing with the U.S. (e.g., Queen is 80″ x 60”), but international equivalents differ (e.g., a UK King is closer to a North American Queen).
The queen mattress (80″ L x 60″ W / 203 cm x 152.5 cm) is the most popular size for Canadian adults. It offers enough space for couples while still fitting into most bedrooms comfortably.
Common custom sizes include Olympic Queen, Double XL, RV King, Small Single, and Alaska King. Many manufacturers can also build custom sizes for boats, trucks, or unique bed frames.
A twin (single) or twin XL is ideal for children and teens. Twin XL is recommended for taller kids or those nearing adulthood.
Yes! Two twin XL mattresses together measure 76″ × 80″, the same as a standard king. This is especially helpful for couples using adjustable bases or wanting different firmness levels.
No. Canadian mattresses follow North American sizing. UK and EU mattress sizes are usually narrower or longer, and naming conventions (like “king” or “single”) can differ. Always check the measurements before purchasing internationally.
Many shoppers now prefer to buy online for convenience, better pricing, and longer sleep trials. Learn more about the pros and cons in our guide to online vs. in-store mattress shopping.
Finding the right mattress size is about more than just measurements, it’s about creating a sleep setup that works for your space, your body, and your lifestyle.
