You can measure how much you have grown by checking your height and weight over time. Doctors use growth charts to make sure you are growing steadily, and the pattern of growth matters more than any single measurement.
Measure each child's height with a tape measure on a wall and record it. Weigh children on a scale. Mark the numbers on a simple chart and compare over weeks or months. Show a sample growth chart and explain what the curved lines mean.
Children often focus on a single number (their height or weight) and compare it to others. They do not understand that doctors care more about the pattern — whether you are growing steadily over time — than about any one number. Some children think gaining weight is always bad, not realizing that gaining weight is a normal and necessary part of growing.
How do you know if you are growing? You might notice your pants getting shorter or your shoes feeling tight. But to really track your growth, you can measure yourself. Stand straight against a wall, have someone mark the top of your head, and measure from the floor to the mark. That is your height. You can also step on a scale to measure your weight. If you write these numbers down and check again in a few months, you can see exactly how much you have grown.
Doctors use a special tool called a growth chart to track children's growth. A growth chart has curving lines that show the typical range of heights and weights for children at each age. When the doctor measures you, they plot your number on the chart and see where it falls. The most important thing is not where your dot is compared to other kids, but whether your dots over time form a steady, consistent line. That steady line means your body is growing at a healthy, predictable rate.
Here is why the pattern matters more than any single number: imagine one child who is short but has been growing steadily for years, and another child who was always average but suddenly stopped growing. The first child is doing great — their body is following its own plan consistently. The second child's change in pattern is what a doctor would want to understand. Growth is about the journey, not a single snapshot. And remember, gaining weight is a normal part of getting bigger. Your bones, muscles, brain, and organs all add weight as they grow. Weight gain is something to track, not something to fear.
