Pet measuring guide

Grab that tape measure! The perfect pet apparel starts with the perfect fit.

Use the tips & visuals in this guide to learn how to measure a pet accurately and easily. If your pet is between sizes, we recommend going up a size for the pet costume that fits best.

How to measure

  • Length

    Run tape from the base of your pet’s neck, at the collar, to the base of their tail, where the back ends and the tail begins.

  • Girth

    Start at the widest part of your pet’s chest, right behind the front legs. Don’t forget to leave a little wiggle room!

  • Neck

    Measure where your pet’s collar naturally goes. Remember to leave a little slack. Two of your fingers should comfortably fit underneath the measuring tape.
