¿Do you have to buy baby clothes but don't know what size to choose?

Are you going to have a baby and you are a little lost on how to choose the size of clothes for your child?

Don't despair, today we are going to give you some guidelines and tips to help you choose the right size of baby clothes. In this way, we will not only avoid having to change it, but it will stay in the closet without the baby getting to wear it for the first time.


As with other clothes, depending on the country you will have to choose one size or another because they have different systems.

In Spain, baby clothes sizes go by months, which makes it much easier to buy them. This means that we will find the clothes cataloged for example 0-1 month, 1-3 months, 3-9 months, 6-9 months and 9-12 months. On the contrary, buying baby clothes in the Nordic countries can be more difficult because they go by height or what is the same by cm. This means that you can find these measures:

size 50: 50 cm long. For newborns.

size 56: 56 cm long. 1-3 months.

size 62: 62 cm long. 3-6 months.

size 68: 68 cm long. 6-9 months.

size 74: 74 cm long. 9-12 months.

size 80: 80 cm long. 12 months.


Another aspect to take into account is that during the first months babies are constantly growing so clothes will last less. For this reason, it is always recommended to choose one more size so that you can take advantage of these clothes for a longer period of time.

And remember to buy onesies or rompers for the first month as they are easier to put on and take off, especially in the diaper area.

When babies are between 3 and 6 months old, a larger size is recommended for one reason, apart from the fact that they grow faster, the diaper. So choose a larger piece for that area. That way, the baby will be more comfortable and it will be easier to dress or change the diaper. If the baby has already reached the stage of 6-9 months, things get a little more complicated. At that age, they are already starting to be fed baby food, so some tend to be chubbier than others. This means that some babies between 6-9 months will use their size, but others will need the size of 9-12 months.
