Getting the size right matters more than most pet owners expect. Too small, and long names or phone numbers get cramped and hard to read. Too large, and the tag can feel heavy or awkward on a smaller pet's collar.
Small (23–25mm)
Best for cats and small dog breeds like Chihuahuas, Pomeranians, and Yorkshire Terriers. Compact and lightweight, so it won't weigh down a delicate collar.
Medium (28–30mm)
Suited to medium dog breeds such as French Bulldogs, Cocker Spaniels, and Border Collies — enough room for a full name and contact number without feeling bulky.
Large (33mm)
A solid choice for larger breeds like Labradors, German Shepherds, and Golden Retrievers, where a slightly bigger tag suits their frame.
Giant (38–40mm)
Designed for giant breeds — Bernese Mountain Dogs, Great Danes, and Mastiffs — giving the most engraving space for longer names or extra details.
A quick tip
If your pet is between sizes, we generally recommend sizing up slightly rather than down — it keeps the engraving crisp and easy to read at a glance, which matters most if your pet ever goes missing.
