The Complete Guide to Choosing the Right Mattress Size

Mattress size is often the first question that comes up when making a purchase. Yet many people choose their format by default, either because it is the size of their old bed or because it is what is available in store.

As a result, they end up with a mattress that is too small for two people, or too large for the bedroom. This guide helps you make the right choice from the start, based on your space, your situation, and the formats available in Quebec.

Mattress size: why this choice has a real impact on sleep

Sleeping in a space that is too tight means spending the night holding back your movements so you do not disturb your partner, or ending up off balance near the edge. This type of physical constraint affects sleep quality, even if you are not always aware of it.

On the other hand, a mattress that is too large for the room can make the bedroom feel cramped, limit movement, and make bedding maintenance more complicated. The ideal size is the one that matches both the available space and the real needs of the people using it.

Standard mattress sizes in Quebec

The dimensions below are expressed in inches, as is standard in the Quebec and North American market. Centimetre equivalents are provided for reference.

Twin: for whom and in what space

The twin mattress measures 38 x 75 inches. It is the standard format for children’s rooms and teenagers. It is also suitable for small guest rooms or bunk beds. For tighter budgets or occasional use, the MATT-2-GO mattress is available in twin size and compresses for easy transport.

For a taller adult, the 75-inch length (191 cm) may be insufficient. In that case, there is the Twin XL (38 x 80 in), which is five inches longer and often used in university residences.

A twin mattress requires a minimum room area of approximately 2.7 m x 3 m to move around comfortably.

Double: the often misunderstood middle option

The double mattress (54 x 75 in) is 16 inches wider than a twin, but keeps the same length. It is comfortable for one person who wants extra space, but remains limited for two adults.

Two adults sleeping on a double each have about 27 inches of width, barely more than a baby mattress. For a couple, it is generally better to move up to a queen.

To take a closer look at the double vs queen comparison, the dedicated article covers all the decision criteria between these two mattress sizes.

Queen: the most popular size in Quebec

With dimensions of 60 x 80 inches, the queen mattress offers 6 extra inches of width and 5 extra inches of length compared to a double. It is the best-selling size in North America, and for good reason.

It suits the vast majority of adult couples and single sleepers who appreciate extra space. The 80-inch length (203 cm) is suitable for people up to about 6 feet tall.

A room of approximately 3.3 m x 3.7 m is recommended for a queen with enough clearance on each side. The LATEXTRA collection is available in queen size and offers durable natural latex, which is especially popular in this format.

King: maximum space for a couple

The king mattress measures 76 x 80 inches. It gives each partner an individual width equivalent to a twin mattress, or 38 inches each. It is the ideal solution for couples who move around a lot, have children or pets sharing the bed, or simply want to maximize their comfort.

The trade-off: it requires a bedroom of at least 3.7 m x 4 m to remain functional, as well as a specific bed frame. King-size bedding is also slightly more expensive and less varied.

California King: designed for taller sleepers

The California King measures 72 x 84 inches. It is slightly narrower than a standard king by 4 inches, but 4 inches longer. It is the recommended size for people over 6 feet 2 inches tall (188 cm), whose feet often hang over the edge of a queen or king bed.

It is important to note that California King bedding is less common in Quebec stores, which can make buying sheets or mattress covers more complicated.

Special dimensions: RVs, custom-made, and non-standard formats

This is a question that comes up often: is it possible to get a mattress in special dimensions? Mattress size can indeed go well beyond standard formats.

Mattresses for recreational vehicles (RVs)

Recreational vehicles often have sleeping spaces with unusual shapes. Common RV formats include:

• RV Short Queen (60 x 74 in): shorter than a standard queen
• RV King (72 x 80 in): narrower than a standard king
• Corner or L-shaped formats for alcoves

These dimensions vary depending on the vehicle model and brand. It is always recommended to measure the available space precisely before ordering.

Custom-made mattresses

Some situations require a mattress with truly customized dimensions: an antique bed with a non-standard frame, a built-in space under a staircase, an attic bedroom, or imported bed furniture with European dimensions.

Special-size mattresses can be produced on request. The RÊVE collection offers adaptable options in particular. Contact the team directly to check what is possible.

It is useful to know that standard European dimensions, such as 90 x 200 cm for a single and 160 x 200 cm for a European double, do not match North American formats. If you buy a European bed frame, check the measurements before buying your mattress.

How to measure your space before buying

Before deciding which mattress size is right for you, here are the practical steps to follow:

• Measure the area of your bedroom, including length and width.
• Leave at least 60 cm of clearance on each side of the bed to move around comfortably.
• Take into account the location of doors, windows, and existing furniture.
• Simulate the size with masking tape on the floor before buying.

Shop all available mattress sizes and find the format that fits your space and your needs.

For couples, also think about your comfort together. The article on the ideal mattress for two people will help you refine this choice based on your sleeping habits.

Conclusion

Choosing the right mattress size is first and foremost about available space and everyday comfort. Queen for most couples, double for single sleepers in a small bedroom, California King for taller people, and custom-made for unusual situations such as RVs.

Take the time to measure your room and simulate the footprint on the floor before deciding. It is the simplest way to avoid choosing the wrong format.

FAQ

What mattress size should a couple choose?

For a couple, the most recommended mattress size is queen (60 x 80 in), which offers good space for each person in most Quebec bedrooms. If space allows, the king (76 x 80 in) gives each partner the equivalent of a twin mattress, or 38 inches of individual width. The format depends above all on the size of your bedroom.

Are custom-made mattresses for RVs available in Quebec?

Yes, some manufacturers can produce mattresses with dimensions adapted to recreational vehicles. The most common RV formats are RV Short Queen and RV King, which are slightly different from standard residential sizes. It is essential to measure the available space in your vehicle precisely before ordering, because dimensions vary depending on the model and year of manufacture of the RV.

Is a California King mattress larger than a standard king?

The California King is longer but narrower than a standard king. It measures 72 x 84 inches compared to 76 x 80 inches for the king. It therefore offers 4 extra inches of length, making it ideal for taller people. However, it is 4 inches narrower, and its bedding is harder to find in Quebec stores.
