You have a 150 cm bed, you're looking at comforters and one comes up in 150. Seems like the answer, right? It's the most common trap, and it's happened to all of us. At that size the comforter has no fabric left to hang down the sides, and that's where the classic 3 a.m. tug of war begins. Getting comforter sizes right is easier than it seems; you just need to know this: the comforter size never matches the mattress size.
So we've gathered everything you need in one place: the two charts (the comforter one and the duvet one, which aren't the same), how to calculate the overhang based on the depth of your mattress, and the special cases that tend to trip people up: 160 cm beds, divan beds, toppers and double beds. And if you came looking for the comforter size for a 150 cm bed or a 90 cm bed, you'll find it in the first chart, no beating about the bush.

why the comforter size isn't your bed size
Think about it for a second: a comforter isn't there to cover the mattress, it's there to cover you. And since we move at night (we all do), it needs plenty of fabric on both sides to keep you covered when you turn over. We call that hanging fabric the overhang, and it's the reason comforter sizes always start from more generous numbers than your bed.
It's easier to see with an example. On a 150 cm bed, a 240 comforter leaves 90 cm of extra fabric which, split between the two sides, becomes 45 cm of overhang per side. That's the point where the bed looks dressed and you stay covered. With a 150 comforter, on the other hand, the fabric would end right at the edge of the mattress: zero overhang and a night of tugging.
To sleep comfortably, the comforter needs a little overhang on the sides.
Something similar happens with the length, although there's more leeway: all our comforters measure 260 cm, a length designed to sit nicely at the foot and head of the bed without you having to keep tugging it into place in the morning.
comforter sizes: three sizes for every bed
The comforter is the piece that goes directly on top of the bed, without a cover, and we have it plain and printed. The sizes are the same for both: three sizes ranging from a single bed to a 180 cm bed. Not much to memorise, you'll see.
| Comforter size | For a bed of | Overhang per side |
|---|---|---|
| 180 × 260 | 80 / 90 / 105 cm | 50 / 45 / 37 cm |
| 240 × 260 | 135 / 140 / 150 cm | 52 / 50 / 45 cm |
| 270 × 260 | 160 / 180 cm | 55 / 45 cm |
Take a look at the right-hand column, because that's where it gets interesting: the overhang ranges between 37 and 55 cm depending on the combination. They all work well, but it helps to know which end you're at. If you have a 105 cm bed, those 37 cm are the comfortable minimum: perfect with a standard mattress, a little tight if yours is on the deep side. And if your bed is 135 cm, the 52 cm give you a generous overhang, the kind that looks good in photos.
The three sizes, one by one
180 × 260 · 80, 90 and 105 cm beds
The single size. It covers everything from the 80 cm bed in a teenager's room to the 105 cm small double. On the 90 cm bed, the most common, it leaves 45 cm of overhang per side.
240 × 260 · 135, 140 and 150 cm beds
The best seller, because it covers the three most common double bed sizes in Spain. On a 150 cm bed it gives 45 cm per side, which is the sweet spot.
270 × 260 · 160 and 180 cm beds
The large size. On a 180 cm bed it leaves 45 cm per side; on a 160 cm bed, a generous 55 cm. If there are two of you and you move around, you'll appreciate the extra room.
duvet sizes: eight sizes
And here comes the detail almost nobody mentions, which explains half the confusion: duvets don't use the same sizes as comforters. They're two different products with two different logics. The duvet goes inside a duvet cover, so its size has to match the cover. No guessing by eye against the mattress.
| Duvet size | For a bed of |
|---|---|
| 140 × 200 | 80 cm |
| 150 × 220 | 80 / 90 cm |
| 180 × 220 | 105 cm |
| 200 × 200 | 120 cm |
| 220 × 220 | 135 / 140 cm |
| 240 × 220 | 150 / 160 cm |
| 260 × 220 | 180 / 200 cm |
| 260 × 240 | 180 / 200 cm · more overhang |
Eight sizes compared with the comforter's three, and with a different length: 200, 220 or 240 cm instead of a fixed 260. Two things are worth looking at calmly.
First: for a 180 or 200 cm bed you have two options, the 260×220 and the 260×240. They differ by 20 cm in length. If your mattress is deep, you use a topper or you simply like the duvet to come well down, the 240 is the one for you. Second: there's a 200×200 size for 120 cm beds that doesn't exist in the comforter chart. If your bed is 120 cm, this is your route.
The duvet and cover rule
If you choose the duvet route, the rule is an easy one to remember: duvet and cover, same size. A 240×220 duvet goes in a 240×220 cover, with nothing to add or subtract. That's exactly why there are eight sizes and not three: each one is already calculated for its cover. The usual slip-up is buying the duvet with the mattress width in mind and then finding it moves around inside the cover or doesn't fit in at all.
how to calculate the overhang you need
You already know the ideal overhang is around 45 cm per side, but that number assumes a mattress of standard depth. If yours is on the generous side, the maths changes: part of the fabric goes on covering the thickness itself before it starts hanging. It's worth grabbing the tape measure for a minute.
The three figures you need
Mattress width
Mattress depth
Actual overhang
Measure the width across the centre of the mattress, not at the corners, which are rounded and give you a shorter figure than the real one. Measure the depth at the side, and if you use a topper or mattress protector, measure with them on: they need covering too. With those two figures you can do the maths:
| Your bed | 25 cm mattress | 35 cm mattress |
|---|---|---|
| 90 cm · 180 comforter | 20 cm overhang | 10 cm · tight |
| 105 cm · 180 comforter | 12 cm · tight | 2 cm · insufficient |
| 150 cm · 240 comforter | 20 cm overhang | 10 cm · tight |
| 180 cm · 270 comforter | 20 cm overhang | 10 cm · tight |
The chart can be summed up in one sentence: with a standard mattress you have plenty to spare; with a 35 cm one you're cutting it fine. If that's you and your bed is 105 or 150 cm, there's no need to settle: go up to the next size and you're sorted. A 240 comforter on a 105 cm bed may seem like a lot on paper, but with a deep mattress it's exactly what's needed.
And if I'm torn between two sizes, which should I choose?
The bigger one, always. It's the only rule in this guide with no ifs or buts. A little extra fabric drapes elegantly and covers you better; a little too little is something you'll notice every time you turn over. Plus, a slightly large comforter can always be tucked under the mattress, whereas a short one simply can't stretch any further. You'll find details of every size in our size guide.
the four cases behind most returns
With the charts in front of you, most purchases work out first time. But there are four situations that are trickier than they seem, so let's go through them one by one.
The 160 cm bed
It's right on the borderline. For a comforter, the size it needs is the 270 × 260, which leaves 55 cm per side. Never drop down to the 240 comforter thinking it's "close enough": the overhang is then only 40 cm, and with a deep mattress you'll notice.
Divan or ottoman bed
A divan base is wider than the mattress and its sides are on show. If you want the comforter to cover them rather than leaving them peeking out, go up one size from what the chart says.
Topper or mattress protector
They add 5 to 8 cm of depth that needs covering, and the overhang chart has already shown you how quickly that eats into the margin. Measure the mattress with the topper on and decide based on that figure.
Shared bed
When the bed is for two, you need more fabric than for one. If one of you ends up uncovered or tugs at the covers, it's rarely about habits: there just isn't enough overhang. One size up and the problem solves itself.
sizes designed for Spanish beds
We design and make in Spain, and there's one place where that really shows: in the sizes. They're calculated for the beds used here (135, 150, 160), not inherited from sizing designed for another market. That's why the 240×260 covers the three most common double bed sizes instead of leaving you short on one of them, and why the duvet comes in eight sizes, including the 120 that many catalogues skip.

now you have your size
To recap, because it's easy: if you're after a comforter, your size is in chart 1 and comes from the width of your bed. If you're after a duvet, it's in chart 2 and has to match the cover. Measure the depth of your mattress if it's over 30 cm and, if you're torn between two sizes, go for the bigger one. With that, there's no room for error.
