FAQ: Sizing


One of the most frequently asked questions I receive is about sizing, especially when it comes to hats. It’s always better to go by the measurement of the hat rather than the size stated. Just because one baby is 2 months old and wears 0-3 month clothing doesn’t mean the next 2 month old is in the same size. They could have already made the jump to 3-6 months or even be in newborn size because they are still a lot smaller.

We are all different and it wouldn’t do for us to be the same.

I know all about sizing issues from experience. Although Kaden travels along, growing at the same rate the "age range" sizes change, Rowan is different. I remember when he was 20 months old he was wearing 18-24 month trousers, the correct size for his age at the time, but most of his shirts and t-shirts were 12-18 months and some were 9-12 months. In fact his coat was a 9-12 month. His torso was growing at a slower rate than his legs and still is. He is almost 3 years old now and I can still get away with some 18-24 month t-shirts on him. I’m sure he’ll catch up with himself but if he doesn’t, he will manage. We all do.


So here are my tips on sizing. I hope they help in deciding which age range to choose when knitting a hat from one of my patterns.



Bonnets

The first measurement needed for a bonnet is the ear to ear measurement.  Place the tape measure at one earlobe, run it up and over the child's head until you reach the opposite earlobe. Measurements are always more accurate with a smaller unit of length so centimetres are the ideal.

  • newborn = 28 cm / 11 in

  • 0-3 months = 30.5 cm / 12 in

  • 3-6 months = 33 cm / 13 in

  • 6-12 months = 35.5 cm / 14 in

  • 12-24 months = 37 cm / 14,5 in

  • 2-5 years = 39.5 cm / 15.5 in




The next size needed is head length. This is taken from the front, centre of the forehead (around where you want the front of the bonnet to sit) and over the head to the crown (the flat part at the back of the head). The measurement must end in the centre of the crown. Again, centimetres are the most accurate for this.

  • newborn =13.5 cm / 5.25 in

  • 0-3 months = 14 cm / 5.5 in

  • 3-6 months = 14.5 cm / 5.75 in

  • 6-12 months = 17.5 cm / 6.75 in

  • 12-24 = 18 cm / 7 in

  • 2-5 years = 19 cm / 7.5 in


These are the average sizes but it doesn’t mean your child is exactly this size. I am a great believer in sizing up since the item will fit eventually, so if in doubt, go bigger.


Beanies

Beanies, aviators, ear flap hats etc have a different sizing method. This is basically anything that isn’t a bonnet.

For this style of hat you'll need the head circumference because this hat travels all the way around the head rather than from ear to ear. Measure at the widest point which is usually a finger space above your child's eyebrows. Keep the tape snug and bring it all the way around the head and back to your starting position. This should encompass the bottom of the crown at the back of the head, which is the lumpy bit that sticks out.

  • newborn =33 – 35.5 cm / 13 - 14 in

  • 0-3 months = 35.5 – 38 cm / 14 - 15 in

  • 3-6 months = 38 – 40.5 cm / 15 - 16 in

  • 6-12 months = 40.5 – 46 cm / 16 - 18 in

  • 12-24 = 46 – 48 cm / 18 - 18.75 in

  • 2-5 years = 48 – 50.5 cm / 18.75 - 19.75 in


As with the bonnet, you would then need the head length. This is taken from the front, centre of the forehead (around where you want the front of the hat to sit) and over the head to the crown (the flat part at the back of the head). The measurement must end in the centre of the crown.

  • newborn =13.5 cm / 5.25 in

  • 0-3 months = 14 cm / 5.5 in

  • 3-6 months = 14.5 cm / 5.75 in

  • 6-12 months = 17.5 cm / 6.75 in

  • 12-24 = 18 cm / 7 in

  • 2-5 years = 19 cm / 7.5 in





So there you have it. The measurements needed to knit your perfect child's hat. I really do hope this helps when trying to decide what size to knit.


Is there anything else you would like to know about sizing? Did I miss anything? Please let me know in the comments below.
