What's my size? Junior boys trouser fitting guide.

A guide to choosing the right size junior boys trousers.

Click on the link below to watch a simple video to help you measure your child for the best fitting boys trousers.



You can choose from three different "fitting" junior boys trousers from Trutex:

Classic fit - slim but not skinny leg, durable Teflon stain resistant fabric

Slim fit - same style as classic with a smaller waist size

Sturdy fit - same style as classic with a larger waist size

To find your right size, check out the size charts below. You will need two key measurements of your child:

  • 1. Waist - for a comfortable fit and to establish which option is best for your child

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 - for the right length trouser

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.

**To note, all our boys trousers have an elasticated back waist for comfort and that bit of essential growth room! And for the sewers amongst you, our hems are wide enough that you can let down if you need to through the school year!
