Using A Tape Measure

The secret to happy, healthy feet? Finding their perfect fit! We’re here to make it easy to measure your child’s feet from the comfort of your home. Though we recommend using our foot gauge, if you don’t have one to hand, it’s simple to suss out their size using a tape measure instead. Please note that this method can only be used if your child can stand unaided. If they are unable to, please visit your local store or purchase one of our Footgauges.

This guide is a great start to getting your child’s fit right - but if you want to make sure it’s spot on, pop into your local Clarks store, where our expert teams will be happy to help.

You will need…

A tape measure, a piece of A4 paper & a pen/pencil.

Find Your Length

  • Step 1:

    Place your child’s foot on a piece of plain A4 paper. Make sure they’re standing up nice and tall, with their feet slightly apart.

  • Step 2:

    Mark the top of their longest toe on the paper (hint: this may not be their big toe!)

  • Step 3:

    Then, make a mark at the longest point at the back of their heel.

  • Step 4:

    Using your ruler or tape measure, measure the point between the two lines in mm.This measurement is your length.

Find Your Width

  • Step 5:

    Place the tape under their foot, mm side up. Top tip: If you don’t have a tape measure, you can use a strip of paper instead.

  • Step 6:

    Run both your index fingers along the sides of their foot, moving forwards from the heel. The first two hard bones you come to are the joints, and these are your measuring points.

  • STEP 7:

    Measure around your child’s foot at these two points, without squeezing the foot. If you’re using a strip of paper, mark these points on the paper and then measure it with a ruler. This measurement is your width.

  • Repeat for both feet.

    Enter your mm measurement in our size calculator below and voilà!

    You’ve got their shoe size.

    If your child’s feet are slightly different sizes, base the size you buy on their largest foot.
