What's my size? Girls trouser fitting guide.

A guide to choosing the right size trouers.

You will need two measurements when finding the right size for your child's trousers -

  • 1 - Waist - to ensure a comfortable fit

Measure your child’s waist by finding the narrowest part of their torso; this is normally a couple of inches above their hip bone and often, but not always, in line with the bellybutton. If your child has no natural narrower part to their torso, take their waist measurement from about halfway between the bottom of their rib cage and the top of their hip bone. Pull the tape measure so it’s snug but not tight against their waist and make sure they’re not holding their breath! You don’t need to add anything to the measurement for comfort as good quality school uniform will be designed with a little bit of ‘ease’ included.

  • 2 - Inside leg - to choose between short, regular or long length

To take the inside leg measurement, ask your child to put on their school shoes and stand naturally. Run the tape measure down their inner leg, from their crotch to an inch or so above the ground where you’d like their trousers to finish. Try to ensure the tape measure is in a straight line, not wrapping around their leg, and don’t pull it too tight or they’ll end up with too-short, uncomfortable trousers.
