Pillow Size: Which Size Is Right For Your Sleep?

The right pillow size determines whether you wake up refreshed in the morning or struggle with neck pain. In Germany, the standard pillow size of 80x80 cm is the most common, but it is not always the best ergonomic choice. Depending on your sleeping position, shoulder width, and body type, a different pillow size may be more suitable. This overview shows you all common pillow sizes, explains their differences, and helps you make the right choice.

Pillow Sizes at a Glance: The Pillow Size Chart

The 5 most common pillow sizes in Germany differ in dimensions, application area, and ergonomics. Here they are at a glance:

Standard Pillow Size in Germany: 80x80 cm

The standard pillow size in Germany is 80x80 cm. This square shape is found in most German households and fits standard bedding sets. Internationally, however, the size 50x70 cm is considered the normal pillow size, a dimension also common in Austria, Switzerland, and many European countries.

The problem with the 80x80 cm pillow: Because it is very wide, side sleepers often have their shoulders resting on the pillow. This lifts the cervical spine (HWS) out of its natural alignment and causes long-term tension. Therefore, those who choose the standard size should opt for a flat pillow with a low filling volume.

For the right pillowcase: Pillowcases 80x80 cm made of 100% cotton OEKO-TEX® certified, breathable, with zipper.

Pillow Size 40x80 cm: The Ergonomic Alternative

40x80 cm is the most highly recommended pillow size from an ergonomic perspective. The elongated format specifically supports the head and neck, while the shoulders rest freely on the mattress. This keeps the spine in its natural S-shape, which is particularly important for side sleepers.

The dimension 40x80 cm corresponds to the so-called standard pillow size, which orthopedists often recommend. It is narrower than the classic 80x80 cm pillow and prevents the head from tilting.

Which Pillow Size Suits Which Sleeping Position?

Pillow size alone does not guarantee good sleep; the right combination of size, height, and filling is crucial. Here are the 3 sleep types with clear recommendations:

Side Sleepers

Recommendation: 40x80 cm or 50x70 cm. Side sleepers need a higher pillow that compensates for the distance between the shoulder and head. The pillow must support the lateral curvature of the cervical spine. A pillow that is too flat tilts the head towards the mattress; one that is too high pushes it towards the ceiling. Shoulder width is the most important factor here: wider shoulders require more pillow height.

Back Sleepers

Recommendation: 40x60 cm, 40x80 cm or 80x80 cm (flat-filled). Back sleepers need less pillow height but good neck support. The pillow should gently support the natural lordotic curve of the cervical spine without pushing the head forward. A 40x80 cm pillow with a medium filling does this best.

Stomach Sleepers

Recommendation: small pillow 40x60 cm or no pillow at all. Stomach sleepers turn their head to the side, hyperextending the cervical spine. A pillow that is too high reinforces this misalignment. Those who sleep on their stomach are best advised with a very flat, soft pillow or a small format. Alternatively, a thin pillow under the stomach can help relieve the lumbar spine area.

Pillow Height vs. Pillow Size: What's More Important?

Pillow height is at least as important as the surface area. Many buyers only pay attention to length and width, but forget that a pillow that is too high or too flat causes neck pain regardless of its size. The optimal height of a pillow for most people is between 8 and 14 cm, depending on sleeping position and shoulder width.

3 factors determine the correct pillow height:

• Sleeping position: Side sleepers need more height than back sleepers
• Shoulder width: wide shoulders = higher pillow needed (12–14 cm)
• Mattress firmness: soft mattress = shoulder sinks in = less pillow height needed

Here's a practical tip: Fitted sheets and bedding made to measure – if the bed setup fits, you'll need less correction work from the pillow.

Filling Material Influences the Effective Pillow Size

Same dimensions, different feel: the filling changes how the pillow performs during sleep. The 4 most common filling materials in comparison:

Standard Bedding Sizes: What Fits Which Pillow?

When buying a new pillow, you should also check whether the existing pillowcase fits. The standard size for bedding in Germany is based on the pillow size:

• 80x80 cm pillow → pillowcase 80x80 cm (classic German size)
• 40x80 cm pillow → pillowcase 40x80 cm (ergonomic standard size)
• 50x70 cm pillow → pillowcase 50x70 cm (international standard size)
• 40x60 cm pillow → pillowcase 40x60 cm (small format / travel)
• 40x40 cm pillow → pillowcase 40x40 cm (decorative pillow)

Important: A pillowcase should be 1–3 cm larger than the pillow so that it does not contract. Pillowcases that are too large will cause the pillow to slip inside. At Terra Beds, all pillowcases are made of stretchy jersey cotton fabric (160 g/m²) – they adapt flexibly to the pillow's shape. Directly to the complete pillowcase collection.

What Do Orthopedists Recommend for Pillow Size?

An orthopedic pillow (orthopedic pillow) differs less in size than in its shape and material properties. Orthopedists do not recommend a specific pillow size across the board; instead, they mention 4 criteria:

• Maintain natural cervical spine curve: the pillow should support the neck, not lift the head
• Shoulder freedom: the pillow ends at the shoulder, not resting on it
• Adaptability: the pillow adapts to the sleeping position
• Breathability: no heat accumulation that disturbs sleep

From these criteria, it follows that 40x80 cm is the format that most frequently meets orthopedic requirements – it leaves the shoulders free and specifically supports the head and neck. The 80x80 cm pillow is comfortable but less precise.

Pillow Size for Children: What's the Right Choice?

Children need smaller and lighter pillows. The recommended pillow sizes by age:

• Babies (0–12 months): no pillow – Stiftung Warentest and pediatricians advise against it
• Toddlers (1–3 years): max. 40x40 cm, very flat
• Children (4–8 years): 40x60 cm, light and soft
• School children (9+): 40x80 cm or 50x70 cm like adults

Terra Beds offers matching children's pillowcases in various sizes – all OEKO-TEX® certified and free from harmful substances. This protects sensitive children's skin.

Frequently Asked Questions About Pillow Size

What is the normal pillow size in Germany?

The normal pillow size in Germany is 80x80 cm. This square format is found in most German households and fits standard bedding. Internationally, 50x70 cm is also a widely used normal pillow size.

How big is a normal pillow?

A normal pillow in Germany measures 80x80 cm. In addition, 40x80 cm is considered the ergonomic standard size, the so-called standard pillow size that orthopedists often recommend. Internationally, 50x70 cm is considered a normal pillow size.

Which pillow size is suitable for neck pain?

For neck pain, 40x80 cm is the most suitable pillow size. The pillow specifically supports the neck and head, while the shoulders rest freely on the mattress. Additionally, pillow height is crucial: side sleepers need 10–14 cm height, back sleepers 8–10 cm.

What is the difference between 80x80 and 40x80 cm?

The 80x80 cm pillow is square and wider; the shoulders often rest on it. The 40x80 cm pillow is narrower and longer; it specifically supports the head and neck without lifting the shoulders. Ergonomically, 40x80 cm is the better choice for side sleepers. Those who prefer comfort and habit choose 80x80 cm.

Which pillow size for standard bedding dimensions?

The standard dimensions for bedding are based on pillow sizes: 80x80 cm pillowcase for the classic standard pillow, 40x80 cm case for the ergonomic pillow, 50x70 cm for international sets. A pillowcase should be 1–3 cm larger than the pillow, never smaller.

Is a small pillow worse?

No. Small pillows, such as 40x60 cm or 40x80 cm, are ergonomically better for many people than large pillows. Size does not mean better support. Crucial factors are pillow height, filling, and whether the pillow suits the sleeping position.

Does the pillowcase have to be exactly the same size?

The pillowcase should be 1–3 cm larger than the pillow. Pillowcases that are too tight will make the pillow firm and alter its supportive properties. Pillowcases that are too large will cause the pillow to slip inside. Jersey cotton is particularly advantageous because it is stretchy and adapts flexibly to all standard pillow sizes. All Terra Beds pillowcases are made of 160 g/m² OEKO-TEX® certified jersey cotton.

Conclusion: The Right Pillow Size at a Glance

The pillow size is not an end in itself; it must match your sleeping position, shoulder width, and mattress. Side sleepers are best served with 40x80 cm. Back sleepers can choose between 40x80 cm and 80x80 cm (flat). Stomach sleepers need a pillow that is as flat and small as possible. The standard pillow size of 80x80 cm is not wrong, but ergonomically not optimal for everyone.

No matter which pillow size you choose: The right pillowcase makes all the difference in quality and sleeping comfort. All Terra Beds pillowcases in sizes 40x40, 40x80, 50x70, 60x60, and 80x80 cm are made of OEKO-TEX® certified cotton, soft, breathable, and washable up to 60°C.
