How to Choose the Right Bedding Size: A Simple Way Not to Get It Wrong

17 July 2026

Buying beautiful bed linen is easy. Finding a set that fits your bed perfectly is far more important.

Even the most expensive fabric will not save the situation if the sheet keeps slipping off, the duvet bunches up inside its cover, and the pillowcases barely stretch over your pillows.

At MALVA DREAMS we have seen it many times: a large share of bedding problems comes not from the quality of the fabric, but from a mismatch in size.

So before you buy, forget the idea that "my bed is a standard one". A standard is only a rough guide. The right choice starts with a tape measure.

Why Does Bedding Size Matter So Much?

Bedding should do more than cover the bed. It has to sit properly, avoid unnecessary folds and stay in place while you sleep.

A poorly sized set can cause several problems at once:

the sheet keeps slipping out from under the mattress;
the duvet cover twists;
the duvet bunches up in one spot;
the pillowcases sit badly on the pillows;
there is not enough sheet left over to tuck in properly;
the bed looks untidy.

And sometimes being off by just a few centimetres is enough for the difference to show.

That is why, when choosing bed linen, you should assess more than colour, print and fabric. The dimensions of every piece matter just as much.

What Should You Measure Before Buying?

There is no need to measure the whole bedroom to the millimetre. To make the right choice, you only need the dimensions of three things:

the mattress — width, length and height;
the duvet — width and length;
the pillows — width and length.

An ordinary tape measure is all you need.

For example, if your mattress is 160×200 cm, you also need to know its height. If you use a topper or a thick mattress protector, factor those in too.

The duvet has to be measured separately. Even a 160×200 cm bed might be used with a 140×200, 150×215 or 200×220 cm duvet.

The main MALVA DREAMS rule: do not choose bedding by the size of the bed if you do not know the dimensions of your duvet and mattress. Take the measurements and choose the size you actually need.

Bedding Sizes: What Do the Set Names Mean?

Names such as "small double", "double", "king" or "family" help you navigate a catalogue quickly. But they should not be treated as exact standards.

Roughly speaking:

small double — most often intended for one person;
double — the classic option for two;
king — usually means wider bedding pieces;
family — a set with two separate duvet covers.

Still, make the final decision only after comparing centimetres.

Approximate size chart

Set type	Duvet cover	Flat sheet	Pillowcases
Small double	150×215 cm	150×220 cm	50×70 cm
Double	180×215 cm	200×220 cm	50×70 cm
King	200×220 cm	220×220 cm	50×70 cm
Family	2×150×215 cm	220×220 cm	50×70 cm

Important: these are approximate formats. Always check the actual contents and dimensions of a specific product before ordering.

What If a Standard Set Does Not Fit?

This happens more often than you might think.

You may have:

a non-standard mattress;
a very tall bed;
a duvet that is larger or smaller than usual;
pillows of an unusual size;
a topper that increases the overall mattress height.

In that case there is no need to give up on the purchase. At MALVA DREAMS you can select individual pieces in the sizes you need, or ask a manager for advice.

Sometimes it is far more practical to assemble your own set — sheet, duvet cover and pillowcases separately — than to hunt for a ready-made one where a single piece does not match your needs.

How to Order Bed Linen Online Without Mistakes

Buying online has one obvious catch: you cannot spread the set out on the bed before paying.

So follow a simple sequence:

Measure the mattress.
Write down its width, length and height.
Measure the duvet separately.
Check the pillow sizes.
Open the description of the specific set.
Compare every dimension in centimetres.

A useful little trick is to save a photo of your measurements on your phone. Next time you will not have to remember whether the mattress was 160×200 or 180×200 cm, or go and measure it all over again.

And if you are in doubt, simply give a manager your exact measurements. MALVA DREAMS will help you work out which option suits your bed best.

Conclusion: The Right Bedding Size Is About Comfort

Good bed linen should work invisibly. You get into bed and never think about straightening the sheet, smoothing out the duvet or pulling a pillowcase back into place.

To get exactly that, follow a simple order: measurements → comparison of dimensions → the right set → comfortable sleep.

Do not choose bedding by the words "king" or "double" alone. Do not go by the size of the bed on its own. Measure the mattress, the duvet and the pillows — and the choice becomes far simpler.

And if you are planning to buy bed linen at MALVA DREAMS and are not sure which format suits you, send us your measurements. We will help you find a set that works not only in a photo, but in everyday use.
