Best Dog Collar for a Great Dane: Size, Fit, and Style Guide
June 25, 2026 · 5 min read

Great Danes are gentle giants, and everything about their gear is scaled up, including the collar. A tall, strong neck needs a wide collar that spreads pressure, and the biggest dogs run beyond standard sizing. Here is how to size a collar for your Great Dane.
Great Dane collar size at a glance
Danes are among the largest breeds. Measure your own dog, since giant individuals run past standard sizes.
| Measurement | Range |
|---|---|
| Neck circumference | 20-26 in (51-66 cm) |
| Typical weight | 99-198 lbs |
| Recommended Dazey size | XL; the largest Danes may need a custom extra-large |
How to measure your Great Dane's neck
The number on the size chart only works if you measure first. Wrap a soft tape measure or a piece of string around the base of your Great Dane's neck, where the collar naturally sits, then keep it snug but not tight. The gold standard is the two-finger rule: you should be able to slip two fingers between the collar and the neck once it is buckled. For the full walkthrough see our dog collar size chart, or let our sizing calculator do the math for you.
- Measure the base of the neck where the collar sits, not up near the head.
- Keep the tape snug, then add room for two fingers.
- Measure to the skin, not over thick fur, so the collar is not secretly too loose.
- If you land between two sizes, size up and use the adjustment range.
Fit notes for Great Danes
A Dane's neck is tall and strong, so a wide collar is the comfortable choice because it distributes pressure rather than concentrating it on a narrow band. Strong hardware is essential too, since even a gentle Dane is a very large, powerful dog.
Great Danes often sit at or beyond the top of a standard extra-large. Measure honestly, and if your Dane is at the larger end, expect to look for a custom or giant-breed extra-large rather than forcing a standard size. As with any large pup, re-measure often while they grow, because Danes get big fast.

Frequently asked questions
What size collar does a Great Dane need?
Most Great Danes measure about 20 to 26 inches at the neck, which is an extra-large. The largest Danes can run beyond a standard extra-large and may need a custom or giant-breed size.
Why does a Great Dane need a wide collar?
A wide collar spreads pressure across a tall, strong neck instead of concentrating it on a narrow band, which is more comfortable and kinder for such a large dog.
How often should I re-measure a Great Dane puppy?
Often. Danes grow remarkably fast, so check the fit every few weeks during the puppy months and use the adjustment range or move up a size as needed.
