Robb Collins

Are you struggling to find the perfect mattress size in Canada? Look no further! In this comprehensive guide, we will walk you through everything you need to know about choosing the right mattress size for your needs. From the cozy Twin to the spacious King, we’ll analyze each size in detail, taking into account the available space in your bedroom, your sleeping preferences (whether you sleep on your back, side, or stomach), and any special considerations you may have.

At Douglas, we understand the importance of a good night’s sleep, which is why we’ve created this ultimate guide to help you make an informed decision. Whether you’re a solo sleeper or sharing a bed with a partner, we’ve got you covered.

Throughout this guide, we’ll discuss the pros and cons of each mattress size, provide tips on how to measure your bedroom space accurately, and offer insights into the most popular mattress sizes in Canada. By the end, you’ll have all the knowledge you need to select the perfect mattress size that will transform your sleep experience.

So, let’s dive in and discover the ideal mattress size for you!

Mattress Sizes in Canada Chart: A Quick Comparison

Douglas, like most mattress companies in Canada, make six mattress sizes. We’ve included this mattress size chart to help you find the perfect size for your needs:

SizeDimensions (Width x Length)Surface Area (Square Inches)
Twin / Single38″ x 75″2,850
Twin XL38″ x 80″3,040
Full / Double53″ x 75″3,975
Queen60″ x 80″4,800
King76″ x 80″6,080
California King72″ x 84″6,048

Note: the sizes above are Canadian. American mattresses tend to be within a 1/2 inch (height/width) of Canadian mattress sizes. Most Canadian sheets and bed frames will fit mattresses made in the US, but its always a good idea to check the dimensions before purchasing.

Standard Canadian Mattress Sizes

Twin mattress

Twin / Single Mattress Size

Dimensions: 38″ x 75″

The most compact and least expensive mattress size offered. Ideal for children and solo sleepers, the Twin is the ultimate solution for homes with space constraints. You’ll typically find this size mattress used in bunk beds, daybeds, guest chambers, and college dormitories.

Twin XL mattress

Twin XL Mattress Size

Dimensions: 38″ x 80″

Is a Twin bed too short? Do your toes hand over the edge? Well … meet the solution! Twin XL has the same width as a Twin but extends an extra five inches in length. It caters to taller individuals who require additional leg space or room for stretching. This adaptable mattress nestles comfortably in a child’s room or a university dormitory. You can also pair two Twin XL’s with a split king adjustable bed frame to make a giant bed for two!

Full / Double mattress

Full / Double Mattress Size

Dimensions: 53″ x 75″

This mattress size offers a substantially larger sleep area than the Twin or Twin XL, making it an excellent choice for single adults or gangly teenagers who prefer more room to sprawl. It’s also works for individuals or couples living in restricted bedroom areas or smaller apartments. A Double will comfortably accommodate most guest rooms and dormitories.

For parents of young children, it might be more economical to skip the Twin and upgrade directly to a Double mattress after the “crib phase.” As children are bound to outgrow a Twin, this strategy spares you the inconvenience of purchasing two mattresses in quick succession.

Are you prone to restless sleep or share your bed with a partner or pet? The Double might be the right fit. However, if you anticipate sharing your sleeping space with both a partner and a pet, you might find the sleeping arrangements somewhat cozy.

Queen Mattress Size

Dimensions: 60″ x 80″

The Queen-sized mattress is the most popular sized mattress on the market. And for good reason! The Queen offers 4,800 square inches, allowing sleepers lots of room to move around, while still being the most cost-effective among the larger mattress categories.

A Queen provides ample sleeping room without seeming overly large or cumbersome. It strikes a balance between allowing ample room for relaxation and yet fitting conveniently into the majority of bedrooms.

A Queen ensures sufficient space for two adults to sleep comfortably side-by-side without feeling confined. It’s also a popular mattress selection for single adults and teenagers.

King Mattress Size

Dimensions: 76″ x 80″

Boasting over 6,000 square inches of sleeping area, the King size mattress is recognized as the most largest standard bed size in Canada. It provides ample individual space for two adults, ensuring optimal freedom to move around. Do you have midnight visits from a pet or child? The King leaves plenty of space for an adult couple with a child, cat or dog, while still allowing everyone to cuddle comfortably.

The master bedrooms is where you will typically find a King mattress.

Although it is designed for multiple sleepers, solitary adults may also appreciate the liberal space that the King size mattress affords.

California King Mattress Size

Dimensions: 72″ x 84″

The California King mattress is built for the tall folks in your life. An added four inches of legroom ensures that your feet won’t dangle over the bed’s edge.

Given its slender profile, the California King size mattress is also an excellent choice for someone who wants a larger bed, but has a narrow bedroom. The King’s slim design may fit nicely rooms with constrained space.

It’s worth mentioning that this mattress affords slightly lesser sleeping surface in comparison to a regular King-sized mattress.

Wait … There Are Even More Mattress Sizes in Canada

Though standard bed dimensions are commonly recognized, a variety of alternate sizes are also available, specifically designed to cater to distinct requirements. Here are a few examples:

Split King Mattress

Podium Split King Adjustable Mattress

Split King (38″ x 80″ each, multiplied by 2)

In essence, a Split King configuration involves two Twin XL mattresses placed on an adjustable bed frame. Each half of the bed can function separately, an advantage for couples with varying sleep preferences and needs.

When positioned together, these two mattresses provide a total of 6,080 square inches of sleeping space, equivalent to the surface of a standard King. A split king configuration, paired with our Adjustable Bed, allows each sleeper to adjust into the perfect position for relief and comfort.

RV Mattresses

If you own a camping trailer or van then you know every bit of space is crucial. To make the most of the compact bedrooms or sleeping quarters in Recreational Vehicles (RV) without squandering any precious area, manufacturers design custom-sized mattresses.

Here are some common RV mattress sizes:

  • RV Bunk (28” x 75”)—a slimmer version of a typical Twin, though maintaining the same length
  • RV Three-Quarter (48” x 75”)—comparable in length to a Full, but somewhat narrower
  • RV Short Queen (60” x 75”)—identical in width to a standard Queen, but five inches shorter

Douglas offers its entire mattress range in these three RV sizes. For added features such as top-tier motion isolation and a machine-washable cover, the Douglas Original RV starts at a reasonable C$599 for the smallest size.

To sweeten the deal, Douglas provides a highly competitive 365-night sleep trial, a 20-year warranty, and a FREE Comfort Sleep bundle with every mattress purchase.

Choosing the Best Mattress Size for You

As you begin shopping, you’re going to see an incredibly wide range of prices across different retailers. And—especially in physical stores—those prices tend to fluctuate on a regular basis. 

From $400 to $4,000 and even more, understanding mattress prices can be confusing—not to mention frustrating. How much should you budget for? Moreover, how do you know when you’re getting a good product for your hard-earned money? 

Here are a few insider tips:

  • First, assess your budget comfort level. Price can vary on a wide range of factors including brand, size, construction materials, and any bells and whistles for added comfort and support. Before you consider any of those things, start simply by determining what price point you’re most comfortable with. After all, the right mattress should give you relief in both your body and bank account! 
  • Don’t base your decision only on price. Given the importance of a good night’s sleep, you don’t necessarily want to go for the cheapest mattress option out there. Often, you get what you pay for in terms of materials and craftsmanship. Less expensive mattresses tend to be thinner, with fewer layers of material. If your mattress is cheaply made, you’ll just be out shopping again sooner than later. 
  • Read reviews. With over 200,000 mattresses sold to date, Douglas has lots of reviews you can read! Use the filter and sort tools to read about what real customers have to say about the features you are most interested in.
  • How many sleepers? Choosing the appropriate mattress size isn’t solely about your own sleeping preferences—it also takes into account the sleeping tendencies of those you share your bed with. It’s essential not to overlook the count of people and pets that join you in your sleep space. The perfect mattress for you should provide sufficient room for everyone involved, guaranteeing a serene slumber without the sensation of being crowded or compressed.

Take the Douglas Original as an example. It features multiple layers of state-of-the-art foam, cooling gel technology, pressure point relief, and motion isolation properties. That’s a lot of premium-level value for a mattress with prices starting at just $599. 

The key takeaway? Even if you have a lower budget, you should still be able to get a great mattress that meets your needs.

Ensuring Proper Support for Your Sleep Position

Another key to selecting your ideal mattress is ensuring it provides proper support for how you sleep at night. 

Remember, we can hold the same position for a very long time when we’re in bed! As such, laying on a mattress with less-than-ideal support can result in prolonged pain and stiffness for your neck, back, and other parts of your body.

Whether you tend to sleep on your back, side, or stomach, different levels of firmness can help provide a more comfortable, higher-quality slumber.

If you are a …Type of mattress support you needType of firmness to look forMattresses to avoid
Back sleeper

Your mattress must help align your spine. However, it must also be cushioned enough to keep your shoulders, hips and lower back comfortable.
Medium-firmStay away from mattresses that are too soft, or that do not provide ample support.
Stomach sleeper
Look for a mattress that provides hip support while keeping your spine in neutral alignment.Medium-firm to firmSteer clear of mattresses that may create excessive sinkage around your midsection.
Side sleeper
Buy a mattress with cushioning that eases stress on your shoulders and hips. Generally, side sleepers need more pressure relief from their mattresses than back or stomach sleepers.Medium-firmAvoid mattresses that are overly cushiony. This is because the gravitational pull can put additional strain on your spine.
Combination sleeper (i.e., you rotate positions through the night)Your mattress should be versatile enough to support multiple positions. Ideally, it will also absorb motion transfer.Comes down to personal preference, but a medium-firm is a safe bet in terms of firmnessDo not purchase a mattress that is too soft or too firm. Since you will be switching up positions all night, you need something that will provide support no matter what.

Just-right firmness, no matter your sleep position

The medium-firm Douglas mattress is crafted to promote properly balanced support and spinal alignment, with just a bit of spring. Each of its layers is made from 2-7 inches of state-of-the-art, Canadian-made foams and components.

So, whether you’re a back, side or stomach sleeper, you should not feel any dips or lumps as you switch or hold positions. Rather, the Douglas molds to and relieves key pressure points—providing you with a more consistent, higher-quality sleep.

Douglas – The Trifecta of Sleep Comfort

Douglas’ award-winning memory foam mattresses provide a balanced trifecta of cooling, support, and cushioning. Whether you select the 10” Original, upgrade to the 11” Douglas Alpine, or go with the premium 12” Douglas Summit. Our highly popular base model, the 10” Douglas Original, includes the following layers:

1 – Cover: Douglas CoolSense®

2 – Top Layer: 2” Luxury ecoLight® Cooling Gel Foam

3 – Transition Layer: 2” Premium Elastex® Foam

4 – Base Layer: 6” Motion Isolation Support Foam

Getting the best bang for your buck isn’t just about price and comfort. It’s also about receiving a top-notch customer experience – not just pre-sale but for years after your purchase. 

As you shop for your mattress, here are a few other considerations to factor into your decision:

Cost and Speed of Shipping

Some retailers will charge you extra for mattress delivery – and then make you wait weeks for it to arrive. Meanwhile, some retailers are the exact opposite – offering free shipping plus quick delivery to your door, often within a few days. This is especially helpful if you want to save a bit of money – plus get your new sleeping experience started sooner than later. 

Length of Trial Period

It can take several weeks – sometimes even months – to adjust to a new mattress. But believe it or not, some retailers will offer up to an entire year-long trial period! This gives you an ideal amount of time to properly decide if your mattress is giving you the quality sleep you need and deserve. Ultimately, the longer the trial period, the better. 

Ease of Returns and Refunds

Trustworthy mattress brands offer hassle-free returns, free pick-ups, and speedy refunds with no hidden stipulations. Just ensure you keep your packaging materials handy until you’re certain of your mattress purchase. That’s because some companies require them back if you decide the item isn’t for you. 

Warranty Term and Wording

Your mattress should provide high-quality sleep for years to come. So, look for a mattress with a lengthy warranty—ideally within the 10-15-year range. That way, you can be sure your purchase won’t let you down any time soon. Also, do your due diligence by reading any fine print upfront. That way, there will be no surprises if any unexpected defects occur. 

Corporate Reputation

Before you buy a mattress, take time to research the brand or retailer in question. Look at industry achievements, awards received and of course what customers are saying. All these factors will help you determine which mattress is best suited to your needs. Plus, you’ll feel more reassured that you’re dealing with a reliable company.

Get to Know Douglas

Not too soft, not too firm. Just right. Douglas’ foam layers work together to provide a firmness that’s suitable for all sleeping positions. Whether you sleep on your back, stomach, or side, you’ll wake up feeling refreshed and ready to start the day.

Cooling Cover

Douglas’ machine-washable CoolSense® cover draws heat and moisture away from the body, giving you a cooler sleep.

Gel Memory Foam

Douglas’ ecoLight® cooling gel foam gently cushions your shoulders, hips, and back for ultimate support and comfort.

Douglas has a calm and relaxing sleep surface. The premium foam layers absorb and neutralize movement before it has a chance to travel across the bed and interrupt your sleep.
