How Much Should a five-year-old Weigh?

When you become a parent you might find yourself obsessing about your child’s body functions. For instance, if they are eating enough or how much they should weigh.

What is the Average Weight of a 5-Year-Old?

Five-year-olds gain 4-5 pounds and grow 2-3 inches per year. The average five-year-old boy weighs 37.5-47.7 pounds while the average five-year-old girl weighs 36.3-44 pounds.

The average weight of a five-year-old doesn’t give us any actual information and this is where the Center for Disease Control (CDC) growth charts come in handy. The CDC growth charts display the range and height of children from 2-20 years.

The CDC charts are a criterion that shows us where a child is in comparison to other children his or her age. These charts help us to ascertain if the weight and height fall in the mid-range, low or high end (what percentile the child’s weight falls in).

Calculating the Body Mass Index (BMI) helps to determine whether your five-year-old is at a healthy weight for their height. The BMI shows the ratio of fat to weight in a body. The Body Mass Index classifies weight as underweight, normal weight, overweight and obese.

The age and sex of a five-year-old are taken into account when determining their BMI. Calculate the BMI by dividing weight in pounds (lbs) by height in inches (in) and multiplying by a conversion factor of 703.

The normal BMI range for a five-year-old boy or girl is 14-17. Below is a free printable for boys and girls offered by CDC if you want to see what percentile your child falls in. Divide the mass by 2.205 to convert pounds to kilograms.





Does a High or Low BMI Mean My Five-Year-Old Child is Sick?

The BMI test is not a diagnostic test. Therefore, don’t worry if the results show your child is overweight or underweight because the BMI does not diagnose him or her with a disease.

However, a high amount of body fat can lead to weight-related illnesses and health issues. At the same time being underweight has its dangers.

The weight of a five-year-old is dependent on the following factors

  • Heredity

Your child’s genetic history is the number one influence on their weight. Look to mom and dad’s height, shape and rate of growth to predict how your child will turn out. For instance, parents who are short and plump tend to have kids who are short and plump whereas those who are tall and lean tend to have tall and lean kids.

  • Health

Some children are born or develop serious medical conditions such as hormone deficiencies and thyroid problems that can affect their weight if not treated. A five year-year-old on corticosteroids used to treat allergies is likely to add weight more rapidly as compared to children his or her age. This is because weight gain is one of the side effects of such drugs.

  • Ethnicity

You might find that children of a certain ethnicity are taller and heavier than their counterparts from another ethnic background. For example, a study that was done by NHANES surveys (1999-2004) showed that US children are both shorter and heavier than their Dutch counterparts.

  • Daily habits

Your child’s daily habits will in some way affect his or her weight. An active five-year-old who plays a lot is less likely to have weight problems. On the other hand, a dormant one who doesn’t like to play might have weight problems.

  • Environment

Children reach their full potential growth when they are in a loving, nurturing and supportive family environment. As a parent, ensure that you provide a conducive environment for your child to grow.

Helping Your Child Grow.

The normal growth of a five-year-old can be aided by;

 Good nutrition

Children won’t grow well without good nutrition. Make sure your five-year-old consumes wholesome calories. Sometimes well-meaning parents can get in the way of a child’s diet. For instance, completely doing away with certain foods which are vital to a child’s growth and development just because they think the child is too big.

The trick here is to be mindful of the portions because at the end of the day the child needs nutrients from the foods you are trying to cut him or her from.

  Plenty of sleep

Ensure your five-year-old gets enough rest since 70-80% of the growth hormone is secreted during sleep. Averagely a five-year-old needs 10-13 hours of sleep over a 24 hour period. Children who take longer naps tend to sleep fewer hours at night and vice versa.

   Regular exercise

Play is an important part of the growth of five-year-olds. Given that they are naturally active, parents and caregivers should encourage them to play. Children at this age should get at least 60 minutes of play every day. This is because physical activity promotes growth by strengthening bones and muscles.

Don’t fret if your five-year-old is not as tall or built as his or her peers. What matters is your child is continuing to grow at a normal rate. Though you can still consult your doctor if you have any concerns about your child’s growth rate.
