Brief answer: The 155x220 duvet is the German comfort size — 20 cm longer and 20 cm wider than the standard size 135x200. It is suitable for people taller than 180 cm, for those who move a lot at night, and for anyone who simply wants more space under the covers. The extra area ensures that the duvet doesn't slip up at the sides and that feet remain covered. BEFA offers all duvets in 155x220 — from lightweight summer duvets to warm winter duvets.
Does this sound familiar? You turn over in your sleep and suddenly one shoulder is exposed. You pull the duvet up — and your feet stick out at the bottom. What many consider normal sleeping comfort is, in reality, a size problem: the standard 135x200 duvet is simply too small for many adults.
The solution is 155x220 cm — the so-called comfort size. In this guide, we explain for whom this size is worthwhile, what to look for when buying a duvet of this size, and how the filling weights change compared to the standard size.
We have been producing duvets in Germany since 1994 — in all common sizes. The 155x220 comfort size is part of our standard range, not a special request.

For whom the 155x220 comfort size is worthwhile
The 155x220 cm size is not a niche product. It is the second most common single duvet size in Germany and is often referred to as the comfort size or extra length. The difference from the standard size is greater than the numbers suggest: the duvet has approximately 26% more surface area than a 135x200 (3.41 m² instead of 2.70 m²).
The comfort size is the right choice for:
- People over 180 cm tall: With a standard duvet, feet stick out or shoulders become uncovered. 20 cm more length solves this problem.
- Restless sleepers: Those who toss and turn a lot at night constantly pull the duvet in one direction. The wider duvet offers reserve — even after the third turn, the body remains covered.
- People with broad shoulders: 155 cm width instead of 135 cm means 10 cm more overhang on each side. The duvet seals better, and cold air penetrates less.
- Comfort lovers: Some simply like more fabric around them. The larger duvet feels more generous and allows you to wrap yourself completely.
From our experience: About 30% of our customers now order the 155x220 size instead of the standard 135x200. The most common reason: "My old duvet was too short." Once you've slept with the comfort size, you generally don't want to go back.
Size comparison: 135x200 vs. 155x220 vs. 200x200
The three common duvet sizes in Germany differ not only in centimeters but also in target group. Here's a quick overview of which size suits your situation. For a comprehensive overview of all sizes, see our duvet size guide.
| Feature | 135x200 cm | 155x220 cm | 200x200 cm |
|---|---|---|---|
| Description | Standard size | Comfort size | Double bed size |
| Area | 2.70 m² | 3.41 m² | 4.00 m² |
| Suitable up to body height | Up to 180 cm | Up to 200 cm | Up to 200 cm (for two) |
| Use | Single person, normal | Single person, comfort | Couple (shared duvet) |
| Bed linen availability | Very good | Good | Good |
| For restless sleepers | Limited | Ideal | Possible, but heavy |
| Typical price (90% down, all-season) | From €169.95 | From €229.90 | From €299.00 |
The price difference between 135x200 and 155x220 is typically 25–40%. This corresponds to the larger fabric area and the additional down filling. Calculated per night slept over its entire lifespan, this is a difference of a few cents — the comfort gain, however, is immediately noticeable.
Filling weight: Why 155x220 needs more down
A common mistake when comparing duvets: directly comparing the filling weights of different sizes. A 155x220 duvet with 350 g filling is not a heavier duvet than a 135x200 with 250 g — it simply has more area to fill.
The crucial factor is the filling per square meter. Only this way can the warmth performance of different sizes be compared:
- Summer duvet 135x200: 250 g on 2.70 m² = approx. 93 g/m²
- Summer duvet 155x220: 320 g on 3.41 m² = approx. 94 g/m²
The same down density per square meter means the same warmth performance. The larger duvet requires absolutely more grams but feels just as light because the weight is distributed over a larger area.
From our production: We calculate the filling quantity for each duvet size proportionally to its area. This means: the down density per square meter remains identical in every size. Whether 135x200 or 155x220 — you get the same warmth performance per unit area.
Quality features: What matters for every size
The 155x220 size does not change the quality criteria that make a good duvet. Whether standard or comfort size — pay attention to these three features:
Fill Power (Loft)
Fill power indicates how much down expands after compression. It is measured according to DIN EN 12130. The higher the value, the better the down insulates for the same weight. Look for at least 120 mm (Class 1) for durable quality. A detailed explanation can be found in our duvet 135x200 buying guide.
Down content: 60% vs. 90%
The down content determines the ratio of down (fluff feathers) to support feathers in the filling. 90% down means maximum lightness and fill power. 60% down results in a slightly heavier duvet with more structure — some sleepers prefer this noticeable weight. For the 155x220 size, the weight difference is particularly clear: a 60% winter duvet can weigh over 1.5 kg.
Cassette stitching
For a larger duvet, the stitching is even more important than for the standard size. More surface area means more space for down to migrate. Cassette stitching with internal baffles keeps the down in its chambers and prevents cold spots. Box stitching (quilted through) is only suitable for light summer duvets, where cold bridges are even desired because they dissipate heat. More on this in our summer duvet material comparison.
Certifications
Three seals are relevant: Oeko-Tex Standard 100 (harmful substance testing, Class 1 is the strictest level), Downpass (no down from live-plucking or force-feeding), and NOMITE (suitable for house dust mite allergy sufferers). These certifications apply regardless of size — a certified duvet in 135x200 bears the same seals in 155x220.
Summer, all-season, or winter — warmth ratings in 155x220
The warmth rating depends on the filling weight per square meter — not on the absolute weight. The filling weights for a 155x220 duvet are accordingly higher than for a 135x200:
Summer duvet (warmth class 1–2)
Filling weight: 300–380 g in 155x220. For room temperatures from 18 °C. Lightweight, breathable, ideal from April to September. Despite the higher absolute weight compared to a 135x200 summer duvet, it feels just as light — the weight is distributed over the larger area.
All-season duvet (warmth class 3)
Filling weight: 650–900 g in 155x220. The all-rounder for bedrooms with constant temperatures (16–20 °C). For most sleepers in heated bedrooms, this is the most practical solution — one duvet for the entire year.
Winter duvet (warmth class 4–5)
Filling weight: 1,000–1,500 g in 155x220. For room temperatures below 16 °C and chilly sleepers. The cassettes are 5–8 cm high to trap maximum air volume. If you don't or hardly heat your bedroom in winter, you need this warmth class.
Manufacturer's tip: For the comfort size, we recommend opting for the next higher warmth class if you're torn between two options. The larger duvet surface hangs further down at the sides — more contact with cool room air. A slightly warmer filling compensates for this.

View nowBed linen in 155×220: Availability and tips
A valid objection to the comfort size: bed linen in 155×220 is not as ubiquitous as in the standard size. The good news: the selection has grown significantly in recent years. All major textile manufacturers and most online retailers now carry bed linen in 155×220.
What you should consider:
- Do not use 135-size bed linen: A 155×220 duvet will not fit into a 135×200 cover. The duvet will be squeezed, lose its loft, and thus its thermal performance. Always buy the appropriate cover.
- Greater selection online: The range in brick-and-mortar stores is limited. Online, you will find the full color selection in 155×220 from most brands.
- Take advantage of set offers: Many providers offer bed linen sets in the combination 155×220 plus 80×80 (pillow) — this is cheaper than buying individual items.
Manufacturer tip: Invest in good bed linen made from cotton satin or percale with a thread count of over 200. The cover fabric lies directly on the down duvet and influences how well the duvet can transport moisture outwards. Cheap polyester covers reduce the climate properties of even the best down duvet.

Frequently asked questions
How many grams should a good down duvet have?
That depends on the size and season. For a 155×220 down duvet: summer duvet 300–380 g, all-season duvet 650–900 g, winter duvet 1,000–1,500 g. The crucial factor is the filling per square meter, not the absolute weight. 320 g of high-quality 90% down in 155×220 will warm as much as 250 g in 135×200 — the down density per area is identical.
What should a good down duvet cost?
A high-quality 155×220 down duvet with 90% down content, Oeko-Tex and Downpass certification ranges between 160 and 350 Euros depending on the warmth rating. The surcharge compared to the standard size is 25–40% and is justified by the larger fabric area and amount of down. Duvets under 80 Euros in this size almost always contain inferior down.
What are the disadvantages of down duvets?
The most common criticisms are: care requirements (wash on delicate cycle, tumble dry with tennis balls), price (high-quality down duvets cost more than synthetics), and allergy concerns (however, NOMITE-certified down duvets are suitable for dust mite allergy sufferers). With proper care, the advantages outweigh the disadvantages: 10–15 year lifespan, unbeatable warmth-to-weight ratio, and better moisture regulation than any synthetic material. Tips for care can be found in our washing guide.
How do I recognize a good down duvet?
Four checkpoints: Fill power according to DIN EN 12130 (at least 120 mm), certifications (Oeko-Tex, Downpass, possibly NOMITE), down content (90% instead of 60%) and baffle box construction. Practical test: Shake the duvet — good down will fluff up immediately and evenly. A dense, slightly rustling ticking indicates a high-quality cover fabric.
Who is a 155×220 down duvet suitable for?
The comfort size is suitable for people taller than 180 cm, for restless sleepers who turn a lot at night, for people with broad shoulders, and for anyone who likes to wrap themselves completely in the duvet. The 26% larger surface area compared to 135×200 makes a noticeable difference in sleeping comfort.
Is 155×220 the same as extra-long?
The term "extra-long" is used differently in retail. Some manufacturers mean only the length (e.g., 135×220), others the combination of width and length (155×220). The size 155×220 is correctly referred to as a comfort size because it exceeds the standard in both width (+20 cm) and length (+20 cm).
Does a 155×220 down duvet fit into a normal washing machine?
Yes, but you need a washing machine with a minimum capacity of 7 kg, preferably 8 kg. Summer duvets also fit into smaller machines. Winter duvets in 155×220 can push the capacity limits — if in doubt, go to a laundromat or use a professional textile cleaning service. Use liquid detergent, no fabric softener, and tumble dry on a low heat setting with 2–3 tennis balls.
Do I need a special bed for a 155×220 down duvet?
No. The down duvet lies on you, not in the bed. A normal 90 cm or 100 cm single bed is sufficient. The duvet will hang a little further down the sides than a 135×200 — this is intended and increases comfort. The comfort size also works excellently as a single duvet on a 140 cm bed.
