The right size is the difference between a cat who poses for the photo and a cat who wriggles out in five seconds. Here is how to measure, and which size to pick.
How to measure your cat
- Neck girth (the one that matters most): wrap a soft measuring tape around the base of the neck, where a collar sits. Leave room for one finger under the tape.
- Chest girth: measure around the widest part of the chest, just behind the front legs.
- Weight (optional): helpful as a sanity check if you are between sizes.
No measuring tape? Use a piece of string or a phone charger cable, mark it, then measure it against a ruler.
Size chart
| Size | Neck girth | Usually fits |
|---|---|---|
| XS | 26 cm / 10.2 in | Young kittens |
| S | 28 cm / 11 in | Kittens and small cats |
| M | 36 cm / 14.2 in | Average adult cats |
| L | 38 cm / 15 in | Large cats and small dogs |
| XL | 40 cm / 15.7 in | Big cats and small dogs |
Measurements may vary by 1 to 3 cm.
Sizes by costume
- Killer Doll costume: XS, S, M, L, XL

Between two sizes?
Pick the larger one. A slightly loose costume is comfortable and stays on; a tight one gets pulled off. If your cat is long and slim, go by neck girth. If your cat is broad chested, size up.
