You grow girl! Here are the facts on growth spurts


Are you feeling a little clumsier than usual? Finding yourself tripping over cracks in the pavement, doormats, your own stupid feet? Don’t worry, you haven’t just woken up one day with the coordination of a baby deer. It’s probably just because you’ve grown a few inches instead.

During adolescence, girls can grow at a rate of up to 8cm per year. That’s the length of an iPhone 6. Or a £20 note. Or Harry Potter and the Order of Phoenix stacked on top of Harry Potter and the Half Blood Prince.

Am I going to be a towering giantess?

It’s hard to say definitively how tall you’ll grow to be, but your height is largely decided by your parents. Your parents’ heights, that is – they didn’t get to fill out a request form. If you have tall parents, you might want to take up basketball. If your parents are on the shorter side, a glowing career as a gymnast or jockey might await you. Or not. Point is, there’s no such thing as a ‘normal’ height – they all have their pros and cons.

If you’re on the smaller size of things, you will always have more legroom on planes, you will never hit your head on doorframes and you can shop in Topshop’s Petite section. If you’re on the taller side of things, you will always be able to reach the top shelf in the supermarket, you might be effortlessly good at the high jump in PE, and you can shop in Topshop’s Tall section. And medium height? Well, Topshop might sell out of 32″ jeans quicker, but at least you’ll never have to grit your teeth while aunties comment on your remarkable stature over Sunday dinner.

How does it work?

Your hands and feet are the first things to grow, so next time you feel your shoes pinching, it’s a pretty good sign that you’re going to have a growth spurt in the not-too-distant future.

Next come your arms and legs, and then your spine. Finally, your hips and pelvis widen, making you less likely to blow over in the wind.

TLDR? Here’s the important stuff:
  • Your height is closely linked to your parents' heights. But tall, short and everything in between is beautiful – so embrace it.
  • Often during your teenage years, growth spurts happen so quickly that your brain struggles to keep up. Hence the tripping over.
  • Growth spurts are often triggered during puberty as the levels of testosterone rise in both boys and girls.
  • Girls generally grow their fastest at 12-13 and tend to finish growing around 18, while boys grow their fastest between 14 and 15 and finish growing around 20.

Often during your teenage years growth spurts happen so quickly that your brain struggles to keep up. Hence the tripping. Your centre of gravity is changing so rapidly that your brain is having to calculate new rules for balancing, like, all the time.

Some people also experience growing pains, which can feel like an intense, cramp-like pain in your legs. Like owls, witches and vampires they generally only come out at night, and will have disappeared by the morning.  

Why now?

Growth spurts are often triggered during puberty as levels of the hormone testosterone rise in both boys and girls. This chemical also causes sexual organs (willies, vaginas, those guys) to develop, which is why these two things often happen at once. It’s kinda like a biological version of synchronised swimming. But not really.

When will it stop?

Girls generally grow at their fastest rate at 12-13 and tend to finish growing around 18. On average, boys grow their fastest between 14 and 15 and finish growing around 20.

So hold onto your hats ladies, we’ve got some growin’ (and tripping over inanimate objects) to do! But whatever height you end up, work it. Every inch of you is A++.
