At age 11, children typically stand between 4 and 5 feet tall and weigh between 70 and 100 pounds. However, weight varies significantly due to factors like genetics, height, and growth rate.

By age 10 or later, children enter pre-adolescence, a period of rapid growth and development. Their bodies undergo significant changes, often leading to noticeable weight gain. Studies suggest that, on average, children gain about 5 pounds per year during this stage.

According to growth charts, the average weight for 11-year-old girls varies between 82.4 pounds (37.4 kg) and 50 kg, depending on individual development.

Several factors determine an 11-year-old’s weight, including:

Genetics

Genetics significantly influence body composition and fat distribution. A child’s weight may differ from average values based on family traits.

Height

Taller children tend to weigh more due to greater bone mass and muscle density. However, body structure varies significantly among individuals.

Growth Rate

Children aged 8-14 experience puberty at different times. Some 11-year-olds have already hit puberty, while others are just beginning.

Geography & Environment

Cultural traditions, dietary habits, and climate can all affect a child’s growth and weight distribution.

Weight is just one aspect of overall health. Here’s how you can help your child develop healthily:

Encourage Proper Sleep

Children at this age require consistent sleep schedules to support growth and cognitive development.

Pro Tip: Monitor your child’s sleep patterns with our Sleep Cycle Calculator to ensure they get the restorative sleep needed for optimal growth.

Promote Healthy Eating Habits

While kids eat a variety of foods, maintaining a balanced diet is key. Encourage them to limit processed snacks, add colorful fruits and vegetables to meals, and share family mealtimes for better eating habits.

Educate About Body Changes

By age 11, children begin learning about puberty and body changes. Parents should provide guidance on sex education, STDs, and physical health.

Support Emotional Well-Being

Beyond weight, emotional health matters. Help kids manage stress, build confidence, and foster positive friendships.
