Cat Collar Size Guide
To keep your cat comfortable, choosing the right collar size is essential. Be sure to measure your cat’s neck and choose the size that provides a comfortable fit.
Key Points
- Measure your cat’s neck circumference with a soft measuring tape or string.
- Short-haired cats: Actual neck circumference + 0.8–1.6" (2–4 cm)
- Long-haired cats: Actual neck circumference + 2.0" (5 cm)
Sizing Guide Your Cat’s Neck Circumference
The "actual neck circumference" is the snug measurement of your cat’s neck without any extra space.
When your cat is relaxed, use a soft measuring tape to measure the narrowest part of their neck. Gently part the fur and place the tape snugly against the neck.
This measurement is your cat’s actual neck circumference. At POPONEKO, the size range that includes the appropriate allowance is shown as "Fits Neck Size" in our size charts.
*Note: If your cat is wiggly or you don’t have a soft measuring tape, you can use a piece of non-stretch string or yarn instead. Measure the length of the string with a ruler.
How to Choose the Right Collar Size
Since the actual neck circumference is a snug measurement, you’ll need to add some extra room when choosing a collar.
As a general rule, add 0.8–1.6" / 2–4 cm for kittens and short-haired cats (about 1–2 fingers of space), and 2.0" / 5 cm for long-haired cats (about 2–3 fingers of space).
If the collar is too tight, it may cause hair loss around the neck. If it is too loose, it can be dangerous, as your cat’s jaw or leg could become caught in the collar. Always measure your cat’s actual neck circumference and choose a collar that provides a safe and comfortable fit.
[Example for a Short-haired Cat]
- Actual neck circumference: 5.9" (15 cm) + Extra room: 1.6" (4 cm) = 7.5" (19 cm)
- Compare your measurement of "7.5" (19 cm)" with the "Fits Neck Size" range in the chart below and select Size M.
[Example for a Longhair Cat]
- Actual neck circumference: 6.7" (17 cm) + Extra room: 2.0" (5 cm) = 8.7" (22 cm)
- Compare your measurement of "8.7" (22 cm)" with the "Fits Neck Size" range in the chart below and select Size L.
