Shar Pei bandana size: 18–22 in square

How do I measure a Shar Pei?

1. Stand the dog square. Use a soft tape where a flat collar sits, on the skin, not over the coat.
2. Snug the tape, then leave room for two fingers. That reading is the neck.
3. Add about 8 inches on the long edge for the knot. Pick the smallest square that covers it.
4. Fold corner to corner. The point rests on the chest, and the knot sits at the side or the back.

What fit notes matter for a Shar Pei?

Cut an 18 in square to a 22 in square for a typical adult Shar Pei neck of 14–20 inches where a flat collar sits. The build to expect is a neck wrapped in heavy folds of skin. That interval is a fitting range for adult pets, not a breed-standard measurement and not a reason to skip the tape on the dog in front of you.

A 14 in neck uses the small 18 in square (long edge about 25.5 in). A 20 in neck uses the medium 22 in square (long edge about 31.1 in). One Shar Pei does not give you the size of the next.

The miss that shows up on a Shar Pei is catching a fold in the tape or burying the knot in a wrinkle. Measure in front of the deepest roll. Keep the knot out of the folds. Weight, a photo, or the size printed on another dog's bandana does not give you the long edge.

Fit the fabric to the anatomy you can feel: a neck wrapped in heavy folds of skin. Fold the square once, corner to corner, and tie the long edge so the point rests on the chest rather than over the eyes or into the water bowl. Two fingers should still slide under the knot after it is snug. If the point drags or the knot pinches a fold of skin, remeasure and recut—do not force a larger square and pull harder.

Measure where a flat collar sits and leave room for two fingers, as in common dog-apparel measuring guidance from the American Kennel Club. Then use this site's square chart rather than a clothing size label.
