Average height for a 4-year-old — and why average isn't the goal

At age 4, most girls measure roughly 95–110 cm (37–43 in) and most boys roughly 96–111 cm (38–44 in). The middle of the range — the 50th percentile — sits around 102–103 cm (about 40 in) for both. Weight typically falls between 13 and 21 kg (29–46 lb).

A range, not a finish line

Those spans cover the 3rd to 97th percentile — the range pediatricians consider typical. Two healthy 4-year-olds can differ by a full head of height. What signals health isn't where your child sits in the range; it's that they keep moving along their own curve.

Measure right before you compare

Home measurements run tall when kids wear shoes or lean. For a fair comparison: shoes off, heels against the wall, standing tall, eyes level. Measure in the morning if you can — we're all a little shorter by evening. Small month-to-month wiggles are noise; the 6-to-12-month trend is signal.

When to check in with a pediatrician

Bring it up at a well-child visit if your child seems to have stopped growing for many months, drops sharply across percentile lines, or is far outside the typical range. Otherwise, occasional tracking plus good sleep, food, and play is the whole job.
