I'm looking at a new bit for my horse
double jointed happy mouth 3-ring which will need bit guards
it only comes in 5" or 5.5"

these are pictures of my horse in a 5" double jointed happy mouth loose ring.

It actually measures about 5.25" so I'm worried that the 5.5" elevator will actually be 5.75" and completely huge but the 5" will be too small.

any thoughts?

thanks!

Usually Happy Mouth bits run a little smaller than the stated size (particularly any of the "fixed" cheeks - dee, full cheek, Baucher, etc).

What is sold as a 5" Happy Mouth here in the states is a 12.5cm bit, which actually equals about 4.9". The 5.5" is a 13.5cm, which equals about 5.31". And the fixed cheeks run a bit smaller than this, even (a 5.5"/13.5 cm full cheek Happy Mouth that I own actually measures even closer to 5.25" than the expected 5.3").

Also, double-jointed bits (of any make) often fit smaller than the equivalent size in a single-jointed or solid-mouthpiece bit.

I would guess that your bit that you *believe* is a 5" is actually a 5.5".

I would definitely get the larger one, it doesn't look like you have much room to play with as is and may need a larger size anyway.

pattnic: I *know* that the bit pictured was sold as a 5" but measures a full 5.25" (who knows, maybe it was packaged incorrectly) so I'm worried that a 5.5" would actually measure 5.75". You say that the fixed cheeks run smaller but I don't believe that a 3-ring qualifies as a fixed cheek bit, would that affect your answer?

I know that the bit pictured is on the small side but I'm worried that a 5.5" bit I order will actually be 5.75" which seems extremely large for a horse with a cob-sized head. Has anyone used/measured a happy mouth 3-ring? does anyone know how the sizing/fit compares to a true to size metalab equivalent?

I don't usually post but I had to on this one. I have a horse who goes in a D ring happy mouth with a roller and a happy mouth pelham mullen mouth. Both bits measure at around 4.7" (I believe the pelham is a touch bigger than that and the D ring is a bit smaller) and they are sold as 4.5".

You could always buy a bit and if it doesn't fit as well as you'd like, return it.

First, take a look at what is stamped on the bit you own. If it is stamped 125mm or 12.5 cm, that is what is sold in the US as a 5". If it is stamped 135mm or 13.5cm, that is what is sold in the US as 5.5". This is based on the distributor catalog.

I own two 5" Happy Mouth elevators. They run slightly small, due to the error in the conversion, but not as much too-small as my full cheek. A 5.5" should *not* measure 5.75".

Also, is it a true Happy Mouth, or is it a knock-off? That could make a difference. What I am saying I only know to be true for actual Happy Mouths... I have no idea about the knock-offs.

You might be surprised at just how big a horse's mouth can be and just how much variance here is between horses. My BO's cob-size gelding takes a 5.75" bit. My cob-size mare takes a 4.75", my cob-size gelding takes 5.25", my friend's horse-size mare takes 5", and my other friend's cob size gelding takes a 4.5".

Take a look at your bits - they should likely be stamped 120mm or 12.0cm. This is the metric measurement which converts to 4.7", though I was unaware that they made them in this size.
