Mattress sizes in Spain: a quick guide to choosing the right one

Choosing the right size mattress is undoubtedly the first step to ensuring a good night's sleep. In Spain, the most common sizes you will find are 90x190 cm for single beds and 150x190 cm for double beds. These dimensions have become the standard because they meet the needs of most people and fit the space available in today's bedrooms.

Quick guide to standard measurements in Spain

Before you rush out to buy one, it is essential that you understand the standard dimensions available on the market. These measurements are not random; they have been established over time for purely practical reasons, adapting to both the average height of people and the furniture we usually have in our homes. Knowing them in advance will save you more than a few headaches and compatibility issues with your bed base, storage bed, or even your bedding.

The purpose of this guide is to give you a solid foundation so you don't get lost. We're going to break down the most common options so you can instantly identify the one that best suits you and your space. Think of it as the map you need to navigate the world of rest without making mistakes.

To begin with, here is an infographic that visually summarizes the three main categories: single, double, and king size. This allows you to associate each name with its most typical use at a glance.

As you can see, each category is designed for a specific profile, from a person who sleeps alone to couples looking for maximum space and comfort.

Why standard measurements?

The standardization of mattress sizes in Spain makes your life much easier when it comes to buying. Knowing that a 150x190 cm mattress is, so to speak, "the new standard" for couples, already gives you a very clear starting point. These are some of the sizes you will see everywhere:

For single beds: The most popular options are 90x190 cm and 90x200 cm. They are perfect for children, teenagers, or adults who sleep alone.
For double beds: For decades, the undisputed king was the 135x190 cm, but today it has been dethroned by the 150x190 cm, which offers that extra personal space that is so appreciated.
For those who want more space: Sizes such as 180x200 cm (the famous King Size) are becoming increasingly popular. They are the ideal choice for those who value generous space to move around freely without disturbing their partner.

A look at the measurements for single beds

When it comes to finding the perfect mattress for one person, it is essential to understand the options available to you. Each size is designed for a specific use and space. In Spain, single beds are not all the same; there is a range of possibilities to suit different needs, from children's bedrooms to adults' bedrooms where extra comfort is desired.

Let's explore these dimensions so you can make the best decision, ensuring that the mattress not only fits in the room, but also gives you the space you need for a perfect night's sleep.

The standard measurement of 90 cm

The 90x190 cm mattress is undoubtedly the most popular single size in Spain. It is the most common choice for children moving out of their cribs, teenagers going through growth spurts, and adults who sleep alone. The reason for its success? It offers the perfect balance between comfort and space efficiency, fitting like a glove in most bedrooms.

Looking back, mattress sizes in Spain have always been very clear, and 90x190 cm has long been established as the standard, accounting for nearly 40% of the market in this segment. Its versatility makes it ideal for trundle beds, bunk beds, and guest rooms. And for taller people, the 90x200 cm variant is the ideal solution, providing those extra centimeters that make all the difference.

The 80 cm mattress for compact spaces

Although not as common, the 80 cm wide mattress is a very ingenious solution for those situations where every centimeter counts. It is especially practical in these cases:

Trundle beds: This is the standard size for the pull-out lower bed. Thanks to its reduced width, it slides smoothly under the main bed.
Very small rooms: In children's bedrooms or guest rooms with limited space, an 80 cm mattress frees up valuable floor space.
Special bunk beds: Some bunk bed designs are made for this width, maximizing the usable space in the room.

However, it should be noted that, although it is a very functional measure, it may be a little tight for an adult of average build if they are going to use it on a daily basis.

The extra comfort of the 105 cm mattress

Known throughout history as "one and a half," the 105 cm wide mattress is the perfect choice for those who sleep alone but want more freedom to move around. This size gives you considerably more personal space than the 90 cm size, but without taking up as much space as a double bed.

Practical tip: Before rushing out to buy a 105 cm mattress, take a look around and make sure you can easily find bedding for this size. Although it is becoming increasingly popular, the variety of sheets and duvet covers may be somewhat limited compared to the standard 90 cm size.

This is a great option for adults who move around a lot at night or who simply value that feeling of spaciousness without having to sacrifice too much room in the bedroom. In short, it's a little luxury for individual rest.

A review of the measurements for double beds

Choosing the size of a double bed is one of those key decisions that makes all the difference when it comes to getting a good night's sleep as a couple. Gone are the days when a single size dominated the market; today, there are many more options to suit all kinds of needs, bedrooms, and lifestyles. From the classic 135 cm mattress to the generous king size, each dimension offers you a completely different sleeping experience.

The key is to find the perfect balance. You need your personal space to sleep without interruptions, but you also have to take into account the limitations of your room. A mattress that is too large can make the bedroom feel cramped, while one that is too small can directly affect the quality of your sleep. To make it clearer, we are going to break down the most popular mattress sizes in Spain for double beds, helping you visualize which one best suits you.

The traditional 135 cm mattress

For decades, the 135x190 cm mattress was the undisputed standard for couples in Spain. Although it has now been surpassed in sales by larger sizes, it remains a very practical option, especially if your bedroom is not very large. Each person has 67.5 cm of space, which can be tight if one of you moves around a lot at night.

This measure is ideal for:

Small bedrooms: Works great in rooms where every inch counts, leaving enough space to move around.
Couples who sleep very close together: If you like to sleep close together or are slim, this may be more than enough.
Individual use with more space: It is also a fantastic option for someone who sleeps alone and wants to enjoy more space.

The star product: the 150 cm or Queen Size mattress

The 150x190 cm mattress, commonly known as Queen Size in Spain, is currently the best-selling and most recommended size for couples. It has become the new standard because it offers the perfect balance: it provides 75 cm of space for each person, a noticeable improvement in comfort without the need for a huge bedroom.

This size represents a real leap in quality when it comes to shared rest. It allows each person to have their own space to move around without disturbing the other. For taller people, the 150x200 cm version is the perfect choice, ensuring that their feet do not hang off the end of the mattress.

The luxury of space: King Size mattresses

For those who prioritize space and comfort above all else, the larger sizes are the ultimate solution. These sizes transform the bed into a true sanctuary of rest.

King Size (160x200 cm and 180x200 cm): These sizes are perfect for couples who value having ample personal space. On a 180 cm wide mattress, for example, each person has 90 cm, which is the same as sleeping together but each in their own individual bed.
Presidential King Size (200x200 cm): This is the largest and most luxurious option on the market. Ideal for families who practice co-sleeping or simply for couples who want to enjoy as much space as possible.

A practical example: Imagine a 12 m² room . A 150 cm wide bed allows you to leave a 60 cm aisle on each side, which is quite comfortable. However, if you put in a 180 cm bed, that space is reduced to only 45 cm, which could make it difficult to walk around and open closets or drawers.

What do the names Queen Size and King Size mean?

When you start looking for a mattress, especially online, it's very easy to come across names like Queen Size or King Size. These terms come from the English-speaking world and, although they are increasingly used in Spain, the truth is that they tend to cause quite a bit of confusion. And with good reason, because they don't always correspond to the measurements we've always used here.

Understanding exactly what they mean is essential to avoid mistakes, especially if you are shopping online. An American king size does not have the same dimensions as one designed for the Spanish market. Therefore, the golden rule is simple: always check the exact measurements before taking out your credit card.

Correspondence between trade names and Spanish measurements

To leave you in no doubt, we have prepared a very clear table that translates these familiar names into standard mattress sizes in Spain. This way, at a glance, you will know what size each one refers to and see those small (but crucial) differences with the standards of other countries.

Trade name (International)	Standard measurement in Spain (cm)	Key difference from the international standard
Twin / Single	90x190 cm or 90x200 cm	The American Twin tends to be slightly wider (96.5 cm) and shorter (189 cm), so it is not an exact replica.
Double / Full	53x74 inches	It is quite similar to the American Full in width, but the length may vary. It is our classic double bed.
Queen Size	150x190 cm or 150x200 cm	Here comes one of the biggest confusions. An American queen size bed is wider and longer (152x203 cm). In Spain, we have "adopted" this name for our popular 150 cm mattress.
King Size	63x78 inches or 71x78 inches	In Spain, the term King Size is used more flexibly. Sometimes it refers to 160 cm and other times to 180 cm. The US Standard King is considerably wider (193x203 cm).
Presidential King Size	200 x 200 cm	This is the largest size, offering maximum comfort and space. One of the most luxurious options you will find on the Spanish market.

As you can see, relying solely on the name is risky. What one Spanish manufacturer calls King Size (160x200 cm), another may reserve for 180x200 cm. This lack of a clear standard for trade names means that the smartest thing to do is to ignore the "surname" and focus only on the numbers.

Why centimeters are the only thing that matters

The table makes it clear: the equivalencies are not mathematical. It is a commercial adaptation.

Be careful, especially if you buy imported bedding. A fitted sheet for an American queen-size bed will not fit a Spanish 150 cm mattress. Those few centimeters of difference make all the difference.

For example, at Morfeo we are very clear about dimensions. A model such as the 150x190 cm —the most sought after by couples for its perfect balance between space and comfort—is identified by its measurements, not by a name that could be misleading. At the end of the day, the only information that guarantees that the mattress will fit your bed frame, that the bedding will fit like a glove, and, most importantly, that it will fit in your room, is the dimensions.

How to choose the perfect mattress size for you

Choosing the right mattress size in Spain is much more than a matter of taste. It is one of those decisions that makes a difference to the quality of your daily rest. To get it right, there are three factors you cannot overlook: your own physical characteristics, whether you sleep alone or with someone else, and, of course, the actual space you have in your bedroom.

Finding the perfect balance between these three points is the secret to ensuring that your new bed is an investment you won't regret. Don't be swayed solely by the idea of having a giant mattress; a well-considered choice will give you comfort tailored to your needs and maintain the functionality of your bedroom.

Your height and build are the starting point.

Here's the golden rule, as simple as it is fundamental: your mattress should be between 15 and 20 centimeters longer than your height. This margin is key to being able to stretch out comfortably, without your feet hanging off the end and with plenty of room for your pillow.

Think of it this way: if you are 1.85 m tall, a 190 cm long mattress will be too short and you will be forced to curl up to fit. That's not the idea. In your case, the ideal solution would be to go straight for a 200 cm long mattress to ensure a truly restful night's sleep.

In Spain, standard sizes have evolved to match the average height of people, which today is around 170 cm for women and 176 cm for men. Although the 190 cm length remains the best seller (accounting for 60-70% of sales), 200 cm mattresses are gaining ground and now account for almost 25% of the market.

Who is going to sleep in the bed?

The next big question: how many people will be using the mattress? The answer changes everything in terms of space and comfort requirements.

For one person: A mattress that is 90 cm or 105 cm wide is usually more than enough. The 105 cm mattress, sometimes called a "one-and-a-half," is a delight for those who move around a lot at night or simply like to have more space.
For two people: If you sleep with a partner, the minimum recommended width is 150 cm. This gives each of you 75 cm of individual space, just enough to move around without disturbing the other. Although 135 cm mattresses have been a classic for years, nowadays they can be a bit tight, especially if you are both of average or large build.

The way you sleep also matters. If you're someone who spreads out like a starfish, you'll appreciate every extra inch of width. And if you share a bed, having enough space is key to not disturbing your partner's sleep. If you want to learn more, we recommend our comprehensive guide on how to choose the right mattress.

The size of your room matters, and a lot.

There is little point in buying the most spectacular mattress on the market if you then have to jump over it to get to the closet. To ensure you can move around freely and your bedroom remains a functional space, it is vital to leave a passageway of at least 50-60 cm on both sides of the bed and also at the foot of the bed.

Before you rush out to buy, grab a tape measure and measure your room carefully. Don't forget to take into account where the doors, windows, and closets are. This simple step will save you a lot of trouble and help you visualize how the bed will look, creating a much more harmonious and practical environment.

How to choose the right bed frame or base

Choosing mattress sizes in Spain is only the first step. There is a key piece in this puzzle that many people forget: the base on which your new mattress will rest. To get the best results from your investment in rest, the golden rule is simple but non-negotiable: the box spring or base must have exactly the same dimensions as the mattress.

This synchronization is not an aesthetic whim, but a matter of pure functionality and extending the life of your equipment. A mattress that "dances" or protrudes from its base, even if only by a few centimeters, is subjected to pressure for which it is not designed. The edges are left unsupported, causing accelerated wear and tear and loss of firmness in those areas. In the long run, this not only shortens the life of your mattress, but also robs you of quality sleep.

Types of bases and what you need to know

Not all bases are the same, and the type of mattress you have chosen may be more compatible with one than another. It is essential to understand the specific characteristics of each one so that the combination works perfectly and you get the best night's sleep.

Slatted bed bases: A very popular and versatile option, especially recommended if you have a memory foam or latex mattress. The slats allow air to circulate freely, helping the mattress to "breathe" and preventing moisture or heat from building up. An added bonus of freshness!
Folding canapés: These are the perfect solution for gaining storage space. They offer a completely firm and even surface. The only "but" is that you must ensure that the cover is breathable (with perforations or upholstered in 3D fabric) so as not to stifle the ventilation of the mattress.
Upholstered bases: These provide firm, stable support, ideal for those looking for a firmer feel when sleeping. As with box springs, breathability is a key factor to consider.
Adjustable beds: If you have decided on an adjustable mattress, there is no other option: the base must be of this type. Always check that the mattress is designed to bend without damage and that its measurements fit perfectly with those of the base.

A mismatch between the mattress and the base can be very costly. Imagine placing a 150x200 cm mattress on a 150x190 cm base. Those 10 cm that are left "hanging" will end up deforming the mattress and will most certainly void its warranty.

To avoid these problems and get the most out of your bedding, it's best to be well informed. If you're unsure, you can always take a look at this guide to choosing the perfect mattress base, which will help you make the right decision.

Finding bedding for every size

Choosing the size of a mattress in Spain has a direct and very practical consequence on something we often overlook until the last minute: bedding. Choosing the right sheets, duvet covers, and mattress protectors is key not only to dressing the bed well, but also to ensuring maximum comfort night after night.

Fortunately, the standardization of the Spanish market works in our favor. The vast majority of textile manufacturers focus on producing the most popular sizes, such as 90 cm for single beds and 135 or 150 cm for double beds.

How to calculate the correct size of the fitted sheet

This is where many people go wrong: the thickness or height of the mattress is a crucial factor that cannot be ignored. A fitted sheet that does not take this dimension into account will be too tight, will slip out of the corners with any movement, or will simply be impossible to put on.

To avoid these headaches, the formula is quite simple. You have to add the width of the mattress plus twice its height, and then do exactly the same with the length.

Practical example: For a mattress measuring 150x190 cm with a thickness of 30 cm, you will need a fitted sheet that is at least 210 cm wide (150 + 30 + 30) and 250 cm long (190 + 30 + 30).

The availability of clothing in standard sizes

Opting for standard sizes such as 150x190 cm has one clear advantage: it is easy to find bedding. In fact, 150x190 cm mattresses dominate the market with a 40% share, closely followed by 135x190 cm mattresses (30%).

This popularity means that around 80% of bedding production focuses on these sizes. This ensures you have a huge variety of designs, fabrics, and qualities to choose from, allowing you to personalize your bedroom without any complications. If you're interested in this topic, our detailed guide tells you all about the best sheets for a good night's sleep.

And what about less common measures?

However, if you opt for a mattress with less common dimensions, such as 160x190 cm or a special length of 210 cm, finding bedding can become a real challenge. The selection is drastically reduced.

In many cases, the only solution is to resort to custom-made products, which involve a significantly higher cost and, of course, far fewer options to choose from. For this reason, before deciding on a non-standard size, we strongly recommend that you research the availability of textiles. A dream mattress can lose some of its charm if dressing it becomes a recurring problem.

We answer your questions about mattress sizes

At this point, it's normal to still have some questions. In this final section, we'll get straight to the point to answer those common questions that always come up just before deciding on a mattress. These are clear, concise answers designed to give you that last piece of information you need.

Consider this a cheat sheet or quick guide to refer back to, ensuring you have considered all the important details.

What is the best-selling mattress size for a couple?

Today, the most popular size for couples in Spain is undoubtedly 150x190 cm. With this size, each person enjoys 75 cm of space, which is a giant leap in comfort if you are used to the classic 135 cm mattress.

And if you're lucky enough to have enough space in your room, going for the 200 cm long version is a decision you won't regret, especially if one of you is tall.

If I am 1.80 m tall, do I need a 190 or 200 cm mattress?

For someone who is 1.80 m tall, the choice is clear: a mattress that is 200 cm long. The golden rule, which never fails, is that the mattress should be at least 15 to 20 cm longer than your height.

That extra margin is what guarantees you can stretch out comfortably, without your feet hanging off the end and with plenty of room for your pillow. It's a small detail that makes a big difference to the quality of your sleep.

Keep in mind that choosing the right size is essential for the mattress to perform at its best during its 8 to 10-year lifespan. A mattress that is too small will suffer more pressure in key areas and will wear out prematurely.

Can I return a mattress if I choose the wrong size?

Yes, of course. Most reputable online stores, such as Morfeo, offer a trial period. This means you can sleep on the mattress for a good number of nights to be completely sure you've made the right choice.

If during this time you realize that the item is not right for you, you can easily arrange for a return or exchange. However, it is crucial that you carefully read the store's return policy and trial period conditions before making a purchase.

At Colchón Morfeo, we have all the standard sizes so you can find the one that fits you like a glove. And so you can sleep soundly with your decision, we offer you our 100-night trial. It's the best way to make sure you've chosen the perfect option for your rest. Discover your ideal mattress at morfeo.com.
