Cat Collar Sizing Guide and Measuring Instructions
To put a collar on your cat without stressing them, choosing the right size is crucial. Always measure your cat's neck circumference and select a collar that fits perfectly.
Key Points
- Measure your cat's neck circumference with a tape measure or string.
- For short-haired cats, add 2-4 cm to the nude size.
- For long-haired cats, add 5 cm to the nude size.
How to Measure Nude Size

Nude size refers to the exact measurement of the body without any slack. When your beloved cat is calm, measure the narrowest part of their neck with a tape measure. Gently part their fur and measure snugly around the neck.
This measurement is your cat's nude neck size. At Poponeko, we display the nude size as the "Suitable Neck Circumference".
*If your cat struggles or you don't have a tape measure, you can use cotton thread or a non-stretch string as a substitute, and then measure the length of the string with a ruler later.
How to Choose a Cat Collar Size
Since the nude size is a snug fit, you'll need to allow for some slack when choosing a cat collar. A good guideline is to add 2-4 cm to the nude size for kittens and short-haired cats (enough for 1-2 fingers to fit underneath), and 5 cm for long-haired cats (enough for 2-3 fingers to fit underneath).
Too little slack can cause collar baldness, while too much slack can be dangerous, leading to the collar getting caught in their mouth or slipping around their shoulder. When purchasing a cat collar, always measure the nude size and choose a collar that fits your cat's neck circumference.
[Example for Short-haired Cats]
- Nude size 15cm + 4cm slack = Suitable Neck Circumference 19cm
- Match "19cm" with the "Suitable Neck Circumference (Nude Size)" in the table below and select "M size".
[Example for Long-haired Cats]
- Nude size 17cm + 5cm slack = Suitable Neck Circumference 22cm
- Match "22cm" with the "Suitable Neck Circumference (Nude Size)" in the table below and select "L size".
