We have to buy a new mattress because what we had is old, broken and ruined. Let’s say that at least 1 conversation in 5, with a possible buyer, starts like this. In a thousand different sauces, but it starts like this. After this introduction one always asks, what is the size one needs? But the answer is always vague, not for inexperience, rather for lack of knowledge of how to take the exact measurements of the mattress.

How to measure a mattress?
To begin with, to measure a mattress, you need the right tools. The best of all is the tape measure, which is the soft meter that many of us certainly have at home. Otherwise, a tape measure can be used.
To take the correct size of the mattress it is necessary to take care to keep the meter straight that is perpendicular to the side we are not measuring, so as not to distort the measurement. Keep in mind that the mattress, unless otherwise indicated, must be measured including the cover.
Once the mattress size is taken:
Once the measurement is taken, both in terms of length and width, it must be checked, if it is a standard size, i.e. 190/200 cm in the case of length, for a standard width. In this case, standard widths are 80, 90, 120, 140, 160, 180 cm.
If the size varies by a centimeter or two at most, we have a standard mattress and probably we will have done things right. Otherwise, there are two cases:
We have a non-standard size mattress, which is easier if the bed or slatted bed we use is old, or made by a custom-made carpenter.
Probably we crushed the mattress or held the meter badly, which is why it is perhaps appropriate to resume the measurements, making sure they are correct.
A safe way to avoid mistakes:
Taking the exact measurements of the mattress can be difficult, not so much in the strict sense, as for the fact that the mattress is soft. Therefore crushing it compromises the correctness of the measurements. For this reason, there is a reference regulation produced which allows a measurement margin of 3% more or less than the actual measurement.
