Cat clothing size chart and how to measure
Choosing the right size is crucial for your cat to be comfortable wearing cat clothes. Since each cat's body shape and size vary greatly, always measure your cat before selecting clothes.
Key Points
- Measure your cat while it is standing on all four paws.
- Choose cat clothes based on the chest circumference.
- Nude size + 1cm is the easiest size to put on.
How to Measure Nude Size

Nude size refers to body measurements taken snugly without any allowance. Measure your cat when it is calm and standing on all four paws. You will measure three areas: neck circumference, chest circumference, and back length.
*If your cat becomes agitated or you don't have a tape measure, you can use cotton string or non-stretch cord as a substitute, then measure the string's length with a ruler later.
How to Measure Neck Circumference
Measure the narrowest part of your cat's neck with a tape measure. This is where a collar would sit. Part the fur and measure snugly around the neck.
How to Measure Chest Circumference
Measure the widest part of your cat's torso with a tape measure. This is typically around the base of the front legs. The nude chest circumference is the most important measurement for choosing cat clothes. Measure 2-3 times to ensure accuracy.
How to Measure Back Length
Measure the length from approximately 1cm below the collar position to the base of the tail. Always measure while your cat is standing on all four paws.
How to Choose Cat Clothes Size
Nude size is a snug fit, so when choosing cat clothes, add a small amount of allowance to each measurement. An allowance of about +1cm will prevent it from being too tight and make it easier to put on.
Also, it's more important for the chest circumference to fit correctly than the neck circumference or back length. An ill-fitting chest circumference can lead to unexpected accidents, so please be careful.
●Example of Size Selection
Nude chest circumference 40cm + allowance 1cm = 41cm
Select size M with a finished chest circumference of 43.5cm
