Summer is around the corner, so the local sporting goods store is clearing out their children's winter gear at 50% off. One of the things the kids will need for next winter is some snow pants. But with kids growing so fast, it's hard to figure out what's going to fit them next winter. So even though we might be saving 50% on last season's gear, there's no guarantee that what we're buying will still fit by next winter.
If you've ever looked through your kid's file at the pediatrician's office, you will notice that their height, weight and head circumference are all plotted on these same charts. Here's how it works:
- Find your child's height on the y-axis. In this example, the child is 42.5" (107.5cm) tall.
- Find your child's age on the x-axis. In this example, the child is 5 years, 4 months (metric equivalent unknown :).
- Find out where those coordinates meet, and find the closest percentile curve upon which your child's measurement lies. In this example, the child is on the 25th percentile (the line right below the heavy red line which represents the 50th percentile).
- Since the child in this example will be about six years old next winter, trace that age from the x-axis up to where it intersects with the percentile curve your child is on. On the 25th percentile in this case, it appears that the child will be about 44" (111.5cm) tall by this coming winter. That's a growth of about 1 1/2 inches.
Note that there are different charts to track length/height, weight, head circumference for boys, girls, birth to 36 months, and from 2 years to 20 years old. Be sure you are using the appropriate chart for your child.
