Baby clothes size chart - Sizees (2024)

Below you will find baby size chart clothes and shoes.

First, a question of terminology. A newly born baby is called a newborn, and a baby between 3 and 12 months old - an infant. Baby sizes therefore refer to the first year of a child's life. During this time, the toddler grows very intensively, therefore the size of infants changes quite dynamically (depending on the number of months lived). During the first 3 months, a child may grow up to 10 cm!

The sizes of baby are usually in the standard range from 56 to 86 in EU or 3M to 24M in US. They indicate the toddler's height expressed in centimeters. It should be remembered that there are other values ​​- chest and waist circumference, or even weight - that can also be taken into account. First, let's look at the basic version of the baby size chart:

Every single parent of a baby is surely aware of the fact that while purchasing items of clothing for a little kid, size chart is extremely important and may be of exceptional help while placing orders either in online or in brick-and-mortar shops.

Baby clothes are nowadays made out of top quality materials, which is a guarantee that they will last for a really long time, but the most important thing that has to be taken into account while familiarizing oneself with the size chart of a particular company before making a purchase is the fact that kids grow really fast, so there is no point in purchasing tops, blouses, jeans, or shoes that are perfectly fitting, as after a few months, they will be probably too small and will have to be replaced with some other products.

Therefore, while consulting a size chart available online or hanging from the wall of a shop in your area, remember that even though it may be standardized for children in a given country, it is also worth consider purchasing goods that are at least a bit bigger in order to ensure that the child has something cozy and stylish to wear in the months to come. We are also of the opinion that while buying baby clothes, it is always worth following advices of professionals with perennial experience in their file, because they will undoubtedly be able to provide us with vital pieces of information that will make purchasing the right goods remarkably easier. A single piece of advice may change shopping from a dreadful experience to a fascinating and very satisfying event!

How to dress a baby?

When preparing a layette for a newborn, there is quite a significant problem: we do not know the exact dimensions of our baby yet. Theoretically, we should reach for the size 56, but we are not sure whether the baby will not turn out to be a premature or quite substantial newborn. It is good then to get a few larger sets (size 62) or to invest in emergency bodys in sizes 52 and 62.

As mums themselves say, it is not uncommon for a child to have similar dimensions to its parents at birth. It is enough to read the reports of Internet users on forums to find many examples confirming this theory. Hereditary characteristics can indeed be an important clue - if your husband is 2 meters, consider purchasing a size 62 garment, and when you both weigh less than 3 kg at birth most of your baby's first clothes may be size 56.
