Wide Collars Size Guide
Wide Collars
Measure snugly around the middle of your dog's neck with a tape measure, without leaving any extra space. Our collars are true to size, so a snug measurement will ensure the best fit.
Collar Sizing Explained: Each collar size reflects its inner circumference range. For example, a size S (27-32 cm) means the collar’s inner circumference fits necks measured between 27-32 cm. Based on this, you can decide whether you want a looser or tighter fit, as the inner circumference of the collar corresponds to your pet’s neck size.

Size | Neck Circumference (cm) | Neck Circumference (inches) |
---|---|---|
XXS | 18 - 23 | 7.1 - 9.1 |
XS | 23 - 28 | 9.1 - 11.0 |
S | 28 - 33 | 11.0 - 13.0 |
M | 33 - 38 | 13.0 - 15.0 |
L | 38 - 43 | 15.0 - 17.0 |
XL | 43 - 48 | 17.0 - 18.9 |
For larger breeds, we have designed a slightly different collar width ratio for L and XL sizes to ensure more security and comfort.
