The weight and height of the baby, according to his age, are useful measurements and figures to know his development and growth. Discover the tables that will guide you.
Weight, along with the size of the baby, is another very important indicator in its physical development. From birth to two years, the way to weigh the baby is on a horizontal scale. The first months and until the baby can sit up, the way to weigh him will be lying down.
It is advisable to carry out the weighing without clothes and at the same time. If you weigh it in the pharmacy, try to do it whenever you can and that it does not fit too small, with the same clothes, so that there is not much difference.
The first weeks of the baby’s life are usually weighed once a week. From six months the weight is done once a month. This may vary depending on the indications of each pediatrician or how the baby is evolving.
When the baby is older than two years, his weight is carried out standing on the so-called platform scales.
To find out if the baby’s weight is evolving with respect to normal values, there are also graphs such as standardized growth charts. There is a specific one for each sex. They are the so-called height and weight tables for boys and height and weight tables for girls.
At birth, a baby is considered small if it weighs less than 2.5 kg, while a baby is large if it weighs more than 4 kg. However, the average value is located between both measures; that is to say, around 3 kg.

Below we offer you an indicative table on the average weight that the baby should have according to the age they are at the moment, as well as their size. Of course, we must bear in mind that they are only indicative measures and weights:
How to measure baby’s size:
To measure the size of the baby and until it reaches two years, its measurement is carried out lying down. In this position, what the pediatrician measures is its length and for this he uses a measuring device called a horizontal height rod.
The height rod is provided with two supports:
- The head support remains fixed.
- The support of the feet is movable and extends, which will give us information about the size of the baby and if it is within normal values, for which it is compared with the growth tables, which are standardized tables.
When the baby reaches two years, its height is measured in the standing position, placing it on a vertical height rod and with the heels, back and neck supported backwards on the vertical height rod.
Baby size chart
As we indicated previously, the tables on both the weight and the ideal measurements -sizes- of the baby for boys and girls are above all indicative, which also DOES NOT replace at all the advice of the pediatrician, who will be the one who has the last word regarding the physical condition of your baby.
Therefore, even if your child’s measurements are not within the values indicated for the tables, regarding his age, do not worry too much, since sometimes the figures do not coincide and yet this does not mean that your baby have some kind of growth or development problem.
