Standard and special mattress sizes: How to find the right one!

Standard bed sizes for double mattresses

Choosing the right mattress for your bed starts with understanding the bed frame dimensions. The size of a double bed—meaning the base that supports the mattress—varies depending on the model and design.

Typically, a standard double mattress measures 160x190 cm, but double beds with a length of 200 cm are also available, especially for upholstered beds or storage beds.

But what are the standard mattress sizes? And which mattress size is best suited to your needs? Let’s explore all the available options to help you find the best mattress for quality sleep.

Why mattress size matters for sleep quality

Did you know that in addition to mattress materials, the dimensions of a mattress also impact sleep comfort? The ideal mattress size varies depending on body structure and personal sleeping habits.

Before selecting a mattress, remember that larger mattresses provide more space and better comfort, enhancing your restful sleep experience.

How to measure your bed frame for the perfect mattress fit

Before purchasing a new mattress, check the exact dimensions of your current mattress or bed frame. Many assume bed sizes are standard, but this is not always the case.

To avoid mistakes, grab a measuring tape and measure the inner edges of the bed frame.

Pro Tip: Bed frame sizes are rarely exact, so if your frame measures 161x191 cm, a 160x190 cm mattress will still fit perfectly.

Mattress thickness: why it’s important for support & comfort

The height of a double mattress impacts its comfort, durability, and support.

On average, mattress thickness ranges from 22 to 26 cm, but choosing a taller mattress can significantly improve sleep quality.

• Pocket spring mattresses: 24-30 cm for maximum body adaptability & support
• Traditional spring mattresses: 22-26 cm for classic firmness
• Memory foam mattresses: 20-24 cm for pressure relief & ergonomic support

A thicker mattress ensures better weight distribution, minimizes pressure points, and enhances durability over time.

Choosing the right mattress width for maximum comfort

he mattress width is essential for restful sleep, especially for couples. A narrow mattress can limit movement, while a wider mattress provides more sleeping space and better rest.

However, it’s also important to consider room size—a mattress that’s too large can make a small bedroom feel cramped.

Mattress length: ensure the right fit for your height

The standard mattress length is 190 cm, but if you’re taller than 180 cm, consider a 200 cm mattress to avoid discomfort. A longer mattress promotes proper posture and overall sleep quality, but requires adequate space.

Standard mattress sizes

There are 3 standard mattress sizes available on the market, based on the average body type of the Italian population:

• 80×190 cm for single mattresses
• 120×190 cm for one-and-a-half mattresses
• 160×190 cm for double mattresses

In addition to the standard sizes, there are various options available for different body types. The ideal mattress is one that allows you to stretch both your legs and arms without reaching the edges of the bed.

Therefore, the ideal mattress length should be approximately 15 cm longer than the person’s height. If this is not possible due to space limitations, opting for a wider bed can be a great alternative, as sleeping diagonally comes naturally for better weight distribution.

Now, let's take a closer look at the different mattress sizes available:

1- Single Mattress Sizes (80x190 cm)

The standard size for a single mattress is 80 cm in width and 190 cm in length. This size is recommended for children, while taller individuals may find a 90 cm wide and 200 cm long mattress more comfortable.

At DaunenStep, we offer all nine size combinations for single mattresses, allowing you to significantly improve your sleep quality with just a few extra centimeters.

• 80x190 cm       80x195 cm       80x200 cm
• 85x190 cm       85x195 cm       85x200 cm
• 90x190 cm       90x195 cm       90x200 cm

2 - Queen Mattress Sizes (120x190 cm)

The standard size for a queen mattress is 120 cm in width and 190 cm in length. This size is ideal for those who want maximum comfort without switching to a double mattress. Being larger than a standard single, it allows for a more natural sleeping position. For taller individuals, the 120x200 cm size is recommended.

• 120x190 cm
• 120x195 cm
• 120x200 cm

French mattresses (140x190 cm)

For those who want more sleeping space or need a space-saving solution for smaller bedrooms, a French mattress is an intermediate option between a one-and-a-half and a double mattress. French mattress sizes range from 140 cm in width to 190/200 cm in length.

• 140x190 cm
• 140x195 cm
• 140x200 cm

3 - King Mattress Sizes (160x190 cm)

Choosing the right mattress size is even more important when it comes to a double bed, as it is shared by two people. It is essential to consider both partners’ needs to ensure they each have enough space for undisturbed sleep.

The standard double mattress size is 160 cm wide and 190 cm long. However, for taller individuals, choosing a larger size such as 165×195 cm or 170x200 cm may provide additional comfort.

• 160x190 cm       160x195 cm       160x200 cm
• 165x190 cm       165x195 cm       165x200 cm
• 170x190 cm       170x195 cm       170x200 cm
