Excelente valoración 4,7/5
You have a 150 cm bed, you’re looking at quilts and you see one that is 150 cm wide. It seems like the obvious answer, doesn’t it? It is the most common trap, and we have all been there. At that size, the quilt has no extra fabric to fall down the sides, and that is when the classic middle-of-the-night tug of war begins. Getting the quilt measurements right is easier than it looks; you only need to know this: the quilt size never matches the mattress size.
So we have brought everything together in one place: both charts —the quilt and the duvet filling, which use different measurements—, how to calculate the drop according to the depth of your mattress, and the special cases that often cause confusion: 160 cm beds, storage bed bases, mattress toppers and beds shared by two people. And if you came here looking for the quilt size for a 150 cm bed or a 90 cm bed, you will find it in the first table, straight away.

why the quilt size is not the same as your bed size
Think about it for a moment: a quilt is not there to cover the mattress, it is there to cover you. And because we move at night —all of us do— it needs extra fabric on both sides to keep you covered when you turn over. We call the fabric that hangs down the drop, and that is why quilt measurements always start with more generous widths than the bed itself.
An example makes it clearer. On a 150 cm bed, a 240 cm quilt leaves 90 cm of extra fabric. Split between the two sides, that gives you 45 cm of drop on each side. That is the point where the bed looks properly dressed and you stay covered. With a 150 cm quilt, by contrast, the fabric would finish right at the edge of the mattress: no drop and a night of pulling the quilt back over yourself.
For comfortable sleep, the quilt needs some drop down the sides.
The same idea applies to the length, although there is more room there: all our quilts measure 260 cm, a length designed to sit well at both the foot and the head of the bed without needing constant adjustment in the morning.
quilt sizes: three sizes for all beds
The quilt is the piece that goes directly on top of the bed, without a cover, and we offer it in both plain and printed designs. The sizes are the same in both cases: three sizes covering everything from a single bed up to a 180 cm bed. Not much to memorise.
| Quilt size | For a bed width of | Drop on each 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 |
Look at the right-hand column, because that is where it gets interesting: the drop ranges between 37 and 55 cm depending on the combination. They all work well, but knowing which end of the range you are at helps. If you have a 105 cm bed, those 37 cm are the comfortable minimum: perfect with a standard-depth mattress, but a little tight if yours is particularly deep. And if your bed is 135 cm wide, the 52 cm drop gives you a generous finish that looks especially good in photos.
The three sizes, one by one
180 × 260 · beds of 80, 90 and 105 cm
The single-bed size. It covers everything from an 80 cm bed in a young person’s room to a wider 105 cm single. On a 90 cm bed, the most common option, it leaves 45 cm of drop on each side.
240 × 260 · beds of 135, 140 and 150 cm
Our best-selling size, because it covers the three most common double-bed widths in Spain. On a 150 cm bed it gives you 45 cm on each side, which is the ideal point.
270 × 260 · beds of 160 and 180 cm
The large size. On a 180 cm bed it leaves 45 cm on each side; on a 160 cm bed, a generous 55 cm. If two of you share the bed and move around at night, that extra room is welcome.
duvet filling sizes: eight sizes
And here is the detail hardly anyone explains, and which causes half the confusion: duvet fillings do not use the same measurements as quilts. They are two different products with two different sizing systems. The duvet filling goes inside a duvet cover, so its size needs to match the cover. There is no need to estimate anything from the mattress width.
| Duvet filling size | For a bed width 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 drop |
Eight sizes compared with three for the quilt, and with different lengths: 200, 220 or 240 cm instead of a fixed 260 cm. There are two points worth looking at carefully.
First: for a 180 or 200 cm bed you have two options, 260×220 and 260×240. There is a 20 cm difference in length. If your mattress is deep, you use a topper, or you simply like the duvet to reach further down, the 240 cm length is the one for you. Second: there is a 200×200 size for a 120 cm bed that does not exist in the quilt chart. If your bed is 120 cm wide, this is the route to take.
The filling-and-cover rule
If you choose a duvet filling, the rule is easy to remember: filling and cover, same size. A 240×220 filling goes into a 240×220 cover: there is nothing to add or subtract. That is exactly why there are eight sizes rather than three; each one is already calculated for its matching cover. The common mistake is to buy the filling based on the mattress width and then discover that it moves around inside the cover or will not fit properly.
how to calculate the drop you need
You already know that the ideal drop is around 45 cm on each side, but that assumes a mattress of standard depth. If yours is particularly deep, the calculation changes: some of the fabric is used to cover the mattress depth before it can begin to hang down. It is worth getting the tape measure out for a minute.
The three measurements you need
Mattress width
Mattress depth
Actual drop
Measure the width across the centre of the mattress rather than at the corners, because rounded corners can give you a shorter measurement than the true width. Measure the depthat the side, and if you use a topper or mattress protector, measure with them in place: they need covering too. Once you have those two measurements, you can do the calculation:
| Your bed | 25 cm mattress | 35 cm mattress |
|---|---|---|
| 90 cm · quilt 180 | 20 cm drop | 10 cm · tight |
| 105 cm · quilt 180 | 12 cm · tight | 2 cm · insufficient |
| 150 cm · quilt 240 | 20 cm drop | 10 cm · tight |
| 180 cm · quilt 270 | 20 cm drop | 10 cm · tight |
The table can be summed up in one sentence: with a standard mattress you have plenty of room; with a 35 cm mattress the fit becomes tight. If that is your situation and your bed is 105 or 150 cm wide, you do not have to settle for it: move up to the next size. A 240 cm quilt on a 105 cm bed may sound like a lot on paper, but with a deep mattress it can be exactly what you need.
And if I am between two sizes, which one should I choose?
The larger one, always. It is the only rule in this guide with no exceptions. A little extra fabric falls elegantly and keeps you better covered; a little too little is noticeable every time you turn over. A slightly oversized quilt can also be tucked under the mattress, whereas one that is too short cannot stretch any further. You can find all the measurements in our size guide.
the four cases that cause the most returns
With the charts in front of you, most purchases are straightforward. But four situations cause more confusion than you might expect, so let’s go through them one by one.
The 160 cm bed
It sits right on the boundary. For a quilt, the correct size is 270 × 260, which leaves 55 cm on each side. Do not drop down to the 240 cm quilt thinking it is “close enough”: the drop falls to 40 cm, and with a deep mattress you will notice the difference.
Storage bed base or ottoman bed
The bed base is wider than the mattress and its sides remain visible. If you want the quilt to cover them rather than leave them showing, go up one size from the chart recommendation.
Mattress topper or mattress protector
These can add 5 to 8 cm of depth that also needs to be covered, and the drop table has already shown how quickly that uses up your margin. Measure the mattress with the topper in place and choose your size from that figure.
Bed shared by two people
When two people share the bed, you need more fabric than when one person sleeps alone. If one of you gets uncovered or pulls the quilt across during the night, it is usually not about sleeping habits: there simply is not enough drop. Going up one size often solves the problem.
sizes designed for spanish beds
We design and make our products in Spain, and sizing is one of the areas where that really shows. The measurements are calculated for the bed widths commonly used here —135, 150, 160— rather than inherited from a sizing system created for another market. That is why the 240×260 size covers the three most common double-bed widths instead of leaving one of them in between, and why the duvet filling comes in eight sizes, including the 120 cm option that many ranges skip.

now you know your size
To recap, because it is simple: if you are choosing a quilt, your size is in table 1 and is based on the width of your bed. If you are choosing a duvet filling, your size is in table 2 and must match the duvet cover. Measure the depth of your mattress if it is over 30 cm and, if you are between two sizes, choose the larger one. With that, there is very little room for error.
