What should an 18-month-old's height be?
⚡ Short answer: There's no single "correct" height for an 18-month-old — what matters most is steady progress on your baby's own growth curve, not how close they are to the WHO average.

I'm curious: what should an 18-month-old's height be? What do you recommend?

There's no single "correct" height for an 18-month-old — every child grows at their own pace. According to WHO (World Health Organization) data, typical 18-month-olds have heights around 80–81 cm for girls and 82–83 cm for boys. But a healthy baby can be above or below those averages. What really matters is how your baby is progressing on their own growth curve over time.
So what matters more than one measurement is watching your pediatrician's percentile curve to see how it progresses. That's more meaningful than any single number. One tip for measuring at home: lay your baby on a flat surface and measure from head to heels with a tape measure — standing them against a wall can be misleading.
If you have concerns about height progress, go over the curve with your doctor at the next visit.
