What Mattress Size to Choose for Baby and Child?

Quick answer: For a baby, choose a 60x120 cm mattress (standard) or 70x140 cm (more comfortable). Thickness must be a maximum of 10-12 cm for safety. For a child aged 3 to 10, a 90x190 cm is sufficient. For a teenager, plan for a 90x200 cm or a 140x190 cm depending on bedroom size.

→ Guide: choosing the ideal mattress for your child

Baby Mattress (60×120 cm)

The 60×120 cm baby mattress is the standard for French cribs. It matches the safety regulatory dimensions for infants up to 2 years old. This format is mandatorily firm to avoid any risk of suffocation.

Key points:

• Recommended thickness: 8 to 12 cm
• Suitable materials: high-resilience foam, coconut, natural latex
• Important certifications: OEKO-TEX Standard 100, CertiPUR

Child Mattress (80×160 and 90×190 cm)

For children aged 6 to 12, the 80×160 cm format offers enough space to grow. From age 12, switching to 90×190 cm (junior format) is recommended, especially if the child is over 1.50 m tall.

---

What Mattress Size to Choose for a Single Person?

Quick answer: For a single adult, 90x190 cm is the minimum acceptable but 90x200 cm is preferable if you are over 1.75 m. The 100x200 cm or 120x190 cm offer superior comfort with more room to move. Always plan for a length at least 15 cm greater than your height.

90×190 cm vs 90×200 cm: What's the Difference?

The 90×190 cm remains common in older homes and guest rooms. However, the 90×200 cm is now the standard for an adult, offering 10 extra cm in length, essential for people over 1.75 m.

Golden rule: your mattress must be at least 10 to 15 cm longer than your height.

100×200 cm: The Extra Comfort

This format is gaining ground. With 10 extra cm in width compared to 90×200, it offers significantly superior comfort for people who move a lot in their sleep or share their bed with a pet.

What Mattress Size to Choose for a Couple?

Quick answer: For a couple, 160x200 cm is the European standard and the minimum recommended for optimal comfort. The 140x190 cm suits small spaces but offers only 70 cm per person. The 180x200 cm is ideal for couples with children or pets, or if one partner is tall.

140×190 cm vs 140×200 cm

These two formats are often confused. The difference of 10 cm in length may seem trivial, but it is decisive:

• 140×190 cm : suits couples where neither exceeds 1.75 m. Format common in older Parisian apartments with inherited bed frames.
• 140×200 cm : the recommended standard for any couple, especially if one partner is over 1.75 m. The price difference is generally minimal (€10 to €30).

Our advice: if you're changing mattresses, systematically opt for 140×200 cm rather than 140×190 cm.

160×200 cm: The European Couple Standard

The 160×200 cm format (also called Queen Size in France) is the best-selling for couples. Each person has 80 cm of width, which corresponds to the width of a comfortable single bed.

It's the ideal format for:

• Couples where one sleeps restlessly
• People who suffer from back problems and need space
• Families who occasionally welcome children into bed

180×200 cm and 200×200 cm: Maximum Comfort

These formats, often called King Size, offer exceptional sleeping space. Each person has 90 to 100 cm, as much as a wide single bed.

Attention: these formats require a bedroom of at least 12 to 15 m² so as not to suffocate the space. Also check that you can get this mattress into your home (stairwell, elevator).

How to Choose the Right Mattress Size Based on Your Situation?

Quick answer: To choose the right size, consider three criteria: your body type (length = height + 15 cm minimum), the number of people (90 cm width minimum per adult), and your bedroom size (leave at least 60 cm of passage on each side of the bed). Also check compatibility with your bed base and bed frame.

Criterion 1: Your Body Type

The basic rule is simple: your mattress must be at least your height + 15 cm in length.

Your height	Minimum recommended length
Up to 1.70 m	185 cm (190 cm minimum)
1.70 to 1.80 m	195 cm (200 cm recommended)
1.80 to 1.90 m	200 cm minimum
Over 1.90 m	200 cm (consider custom)

Criterion 2: Number of People

• Alone: 90×200 cm (tight budget) or 100×200 cm (comfort)
• Harmonious couple: 140×200 cm minimum
• Couple with different sleep styles: 160×200 cm ideal
• With occasional children/pets: 160×200 cm or 180×200 cm

Criterion 3: Your Bedroom Size

Here are the minimum recommended areas by mattress format:

Mattress size	Minimum bedroom area
90×200 cm	9 m²
140×200 cm	10 m²
160×200 cm	12 m²
180×200 cm	14 m²
200×200 cm	16 m²

These dimensions assume keeping at least 70 cm of clearance on each side of the bed to move comfortably.

How to Check Compatibility Between Mattress, Bed Base, and Bed Frame?

Quick answer: Your mattress must exactly match the dimensions of the bed base and bed frame. For slatted bases, the gap must be less than 7 cm. For bed frames, check the interior dimensions and the depth of the recess. A mattress that is too thick will stick out of the frame, and one that is too small will leave uncomfortable gaps.

Slatted Bed Base

The slatted bed base is the most common in France. It adapts to all mattress sizes. For queen and king formats, check that the base has a central reinforcing slat to prevent sagging in the middle.

Tip: with a memory-foam or latex mattress, space the slats 4 to 6 cm maximum for optimal support.

Upholstered Bed Base

This type of bed base, covered in fabric, is fixed and offers a uniform surface. It suits all mattress types. Be careful with natural latex mattresses that absolutely require a ventilated surface — so prefer a slatted base in this case.

Bed Frames and Headboards

Before any purchase, measure the inside of your bed frame precisely. Tolerances are generally +/- 1 cm. A mattress that is too small in a frame can slip; too large, it won't fit.

Good to know: European bed frame dimensions are standardized to the same formats as mattresses (90, 140, 160, 180 cm).

Sheets and Mattress Protectors

Remember to check the compatibility of your bedding:

• Standard 140×190 cm fitted sheets do NOT fit a 140×200 cm mattress
• Mattress thickness is also decisive: fitted sheets come in 25, 30, 35, and 40 cm depths

Special Cases and Custom Sizes

Large Sizes (Over 200 cm)

People over 1.90 m may feel cramped even on a 200 cm mattress. Some brands offer elongated formats at 210 or 220 cm. Count on an extra cost of 20 to 40% compared to the standard format.

Bunk Beds and Cabin Beds

These beds often use non-standard sizes: 80×180, 80×190, 90×180 cm. Always measure the inside of the frame before ordering.

Murphy Beds (Wall Beds)

These systems have their own weight and thickness constraints. The mattress must generally not exceed 18 cm in thickness to work properly with the lifting mechanism.

FAQ: Mattress Sizes

What is the standard size of a double mattress?

160×200 cm is the standard size for a couple in France. It's the best-selling and most recommended format by sleep specialists, as it gives each person space equivalent to a single bed.

What is the difference between 140×190 and 140×200?

10 cm of extra length, recommended for people over 1.80 m. If your current bedding is 140×190, check whether your bed frame can accommodate a 140×200 before ordering.

Can you find mattresses in 160×190 cm?

This format exists but is uncommon. It's often associated with old bed frames. If you can, prefer switching to 160×200 cm for better comfort.

Is a 160×200 mattress suitable for sleeping alone?

Yes, absolutely. Sleeping alone on a large mattress has no drawbacks — on the contrary, you benefit from generous sleeping space. The only constraint is the bedroom size.

How do I measure my bed base before buying?

Measure the inside of your existing frame or bed base in length and width. Add 1 to 2 cm of margin. If your bed base measures 159×199 cm inside, a 160×200 cm mattress will fit perfectly.

Conclusion: Which Size to Choose?

The choice of mattress size depends above all on your body type, lifestyle, and bedroom. In summary:

• Alone: 90×200 cm minimum, 100×200 if possible
• Couple: 160×200 cm is the ideal standard
• Maximum couple comfort: 180×200 cm if the bedroom allows
• With children: always check size + 15 cm

Investing in the right format is also investing in the quality of your sleep for the next 10 years. Don't skimp on a few extra centimeters — you won't regret it.
