Hybrid Headcollar Sizing Guide


Use either breed/height or measurements on chart below to choose your halter!

Things to know about HYBRID sizing:



  • It is okay if your halter is snug under the chin when you first try it on.
  • If it is snug, tighten the nose knots with your hands. Also make sure that the eyelets on the jowl are pulled down as shown in the photo (it makes things look neater and will also give you some sizing play)
  • With use, the splices will tighten down and elongate slightly, in most cases giving you the perfect amount of play for the horse to open his mouth to yawn, chew, drink, blow and for the ring to have the best effect
  • A tailored fit is preferred. If you've used rope halters for years you might be expecting that fit, which is rather sloppy in comparison to the Hybrid (think a button down shirt versus a t shirt).
  • Ideal clearance under chin is at least one finger of space under the chin once the halter has been used for a few sessions. If you have a good fit in the jowl and poll, but much more play under the chin than a few fingers, you'll also be fine. The HYBRID has a wide latitude of effectiveness based on sizing, it being looser around the nose will not have any detrimental effects, however, in that case, you may want to try this next tip to shorten the poll strap without burning additional holes in the webbing...
  • If your halter is a little too big, you can loop the poll strap back through itself on the off side. This is a great trick and we routinely use it so that a larger halter will fit a growing young horse (see photo with green webbing)
  • horse halter fitThe photo shows a properly fitted average halter fresh from the box which will loosen with use to what we would call an ideal fit. If your halter looks like this on your horse when it arrives, do the happy dance! Looser is okay as well.

 *Dee to dee measurement is measured from side dees on either side of the horse's face, over the top of the poll to the opposite dee.

If you are close to the maximum of a size - go up one size for best results. Your horse is not worried that his head is too big and most people who exchange exchange for a larger size, as normal headcollars are not fitted like the Hybrid.
