Mastiff bandana size chart: 26–30 in square

How do I measure a Mastiff?

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 Mastiff?

Cut a 26 in square to a 30 in square for a typical adult Mastiff neck of 24–34 inches where a flat collar sits. The build to expect is a massive neck with deep folds and a short coupling to the shoulders. 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 24 in neck uses the large 26 in square (long edge about 36.8 in). A 34 in neck uses the extra large 30 in square (long edge about 42.4 in). One Mastiff does not give you the size of the next.

The miss that shows up on a Mastiff is a shop large that cannot clear the folds to knot. The long edge must clear the rolls and still leave knot room. 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 massive neck with deep folds and a short coupling to the shoulders. 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.
