Each mommy sooner or later asks herself the question: “Is the baby developing correctly?”. It seems to one that the child is too calm, to others, on the contrary, that he is too active, for some the child is overweight, for others it is “losing weight.” In order to understand the correct development of their offspring, each mother finds her own solutions, whether it be a consultation with a doctor or a search for answers on the World Wide Web.
When a child grows up, he is no longer such a defenseless lump, and it may seem that the difficulties are behind, but this is only an appearance. With age, a large number of changes occur in a small organism. And all parents care about how the child should develop properly. One of the most often exciting questions for parents is the rate of height and weight for girls and boys. And all because this is perhaps one of the few visible indicators of the development of young creatures.
It should be noted that boys and girls develop in different ways, therefore, you need to write about them separately.
Growth and weight for girls
It is inherent in nature that boys are larger and taller, and girls are fragile, small and slim. But not only the gender of the child determines the accuracy of growth and weight. You need to understand that figures showing the ratio of height to weight for girls are approximate. Indeed, in different nationalities different external signs, for example, a European and a representative of East Asia will clearly differ in growth. Another factor that mismatches the parameters is lifestyle and nutrition.
There is a so-called psychological factor, that is, sometimes it seems to a girl that she has extra pounds, and she takes all kinds of actions to solve this problem. But this factor is characteristic of girls from 14 years of age and older. Also, one should not forget about heredity. In any case, even when determining all factors, the norm of height and weight for girls may differ. After all, people tend to be different, to have different muscle and bone mass, different features of growing up.
Weight and height chart for teenage girls
Although everyone develops in different ways, but tables of approximate indicators are still available and are widely used by teenage therapists. The data in this table is regularly updated, as well as the statistical rate of height and weight for girls is updated.
The tables clearly illustrate the current standard in this regard. It should be noted that the height and weight for girls are shown in three columns: a very low level of height / weight, medium and very high.
Growth rates for girls| Age years | Height, cm very low | Height, cm middle | Height, cm very tall |
| 7 | 111.1 | 116.9-124.8 | 131.3 |
| eight | 116.5 | 123.0-131.0 | 137.7 |
| nine | 122.0 | 128.4-137.0 | 144.8 |
| ten | 127.0 | 134.3-142.9 | 151.0 |
| eleven | 131.8 | 140.2-148.8 | 157.7 |
| 12 | 137.6 | 145.9-154.2 | 163.2 |
| 13 | 143.0 | 151.8-159.8 | 168.0 |
| fourteen | 147.8 | 155.4-163.6 | 171.2 |
| fifteen | 150.7 | 157.2-166.0 | 173.4 |
| 16 | 151.6 | 158.0-166.8 | 173.8 |
| 17 | 152.2 | 158.6-169.2 | 174.2 |
Weight table
As for weight, the averages look like this.
Weight Standards for Girls| Age years | Weight, kg very low | Weight, kg middle | Weight, kg very tall |
| 7 | 17.9 | 20.6-25.3 | 31.6 |
| eight | 20 | 23-28.5 | 36.3 |
| nine | 21.9 | 25.5-32 | 41 |
| ten | 22.7 | 27.7-34.9 | 47.4 |
| eleven | 24.9 | 30,738,9 | 55,2 |
| 12 | 27.8 | 36-45.4 | 63,4 |
| 13 | 32 | 43-52.5 | 69 |
| fourteen | 37.6 | 48.2-58 | 72,2 |
| fifteen | 42 | 50.6-60.4 | 74.9 |
| 16 | 45,2 | 51.8-61.3 | 75.6 |
| 17 | 46.2 | 52.9-61.9 | 76 |
If one of the parameters of the table (weight or height) corresponds to a very low or very high value, then you should not immediately sound the alarm and take the teenager to specialist doctors. The fact is that a young organism tends to develop faster or slower. If, for example, the child is very tall, but his weight, on the contrary, is very low, then this situation indicates a so-called sharp growth spurt. The same applies to a sharp jump in body weight in the direction of increase. It is much worse if weight and height are close to the lower limits of the norm. Such a picture may indicate problems in the development of the child.
Weight and height for a 12 year old girl
As you know, 12 years is a turning point for a young lady, from a girl she begins to turn into a girl. And these changes, physical and psychological, are very noticeable. The girls' body is being rebuilt, the metabolism is accelerating, which, in turn, leads to a smaller gain in body weight. Weight and height for a girl of 12 years old are those indicators about which parents should least worry. At this age, a slowdown is possible, some decline in physical development (in the limit of norms), but everything will be restored in the process of maturation of the girl. Of course, the onset of puberty in each girl occurs at different times, and 12 years is not always a tear-off point.
Body mass index
The approximate height of the girl before the onset of “transitional age” should be in the range of 137–164 cm, weight can range from 27–64 kg. If parents still have anxiety about their child’s body mass, then try to calculate the body mass index. This is the right way to check, suitable for any gender and age.
To calculate the body mass index, weight should be divided by the square of growth. For example, weight 48 kg, height 1.56 - then 48: (1.56 * 1.56), i.e. 48: 2.4336, equal to 19.72.
The value from 19 to 25 refers to the norm of the body mass index. If this indicator is less than 19, then this indicates a lack of weight, and if more than 25 - then an excess.
The transition period in girls
The transition period for a girl is a complex process of emotional and physical reconstruction of a young body. The child begins to perceive the surrounding reality and people in a different way, to see what he previously did not pay attention to. There may come a moment of complete denial of all norms of behavior. Acts go against the odds of everything, but this does not mean that the teenager became a bad person, just the physical changes that occur in this period in the body of a young girl make the nervous system work "for wear and tear", and it’s clear that the girl is not completely understands what she is for. During puberty, puberty occurs , due to which the development processes are accelerated, at first there is a certain delay, after which there is a sharp increase in the growth and weight of the girl. Usually this jump starts from the moment of the first menstruation. Also, for the transition period, the final formation of the girl’s internal organs and the production of a huge amount of hormones are characteristic. At this time, parents should be most attentive to the young girl.
Changes in the body of a teenage girl are natural and come in different ways and at different times. Girls grow and gain weight. To keep parents aware of how well the child is developing, there are various calculation formulas and tables
of height and weight for children.
