# Bandana Gauge > A static measuring aid that maps a dog's neck circumference to a tied triangle bandana square. Bandana Gauge is not a shop and not veterinary advice. It sizes a square folded once on the diagonal, with about 8 inches of long-edge allowance for the knot. Breed pages give typical adult neck ranges as a starting point; the tape on the dog in front of you replaces them. The five squares on this site are 15, 18, 22, 26, and 30 inches on a side. Pick the smallest square whose long edge (side × √2) covers neck + tie allowance. ## Preferred sources - Home / calculator: https://bandana-gauge.pages.dev/ - Size chart guide: https://bandana-gauge.pages.dev/tools/en/dog-bandana-size-chart - How to measure: https://bandana-gauge.pages.dev/tools/en/how-to-measure-a-dog-for-a-bandana - About / method: https://bandana-gauge.pages.dev/about - Privacy: https://bandana-gauge.pages.dev/privacy - Terms: https://bandana-gauge.pages.dev/terms - Contact: https://bandana-gauge.pages.dev/contact - Contact email: seobest2026@proton.me - Sitemap: https://bandana-gauge.pages.dev/sitemap.xml
