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