How to Tell If Your Horse’s Bit Actually Fits (And Why Most Don’t)
Most riders assume their horse’s bit fits
After all, the horse is going in it, right?
But here’s the truth I see every single week working on horses:
Most bits don’t actually fit the horse’s mouth.
Not because the rider did anything wrong
But because we’ve normalized discomfort
And when a bit doesn’t fit, your horse will tell you
Just not always in obvious ways
The problem most people miss
We’ve been taught to look at behavior as a training issue first.
Heavy in the hands
Head tossing
Bracing
Inconsistent contact
So we train through it
But here’s the issue:
You cannot train through physical restriction or discomfort
If your horse cannot comfortably carry the bit
They physically cannot soften into it
Why most bits don’t fit
Here’s something most people don’t realize: The average horse only has about 14mm of comfortable space in the mouth ( based on a study in 2022)
Most bits on the market are around 15mm or thicker
That means many horses are already over capacity
Before we even pick up the reins!
Then we add:
Tongue size
Palate height
Bar sensitivity
And suddenly that “normal” bit isn’t so normal
Signs your horse’s bit may not fit
Some signs are obvious
Some are subtle
Look for:
Leaning or heaviness in your hands
Head tossing or rooting
Opening the mouth or evading contact
Inconsistent connection
Difficulty stepping under or engaging
Tight jaw or lack of chewing
Bracing through transitions
And one people miss all the time:
A horse that looks good but feels disconnected
I had a horse recently who had been working with a rider who was doing everything right.
Lessons, consistency, great rider.
But he still felt heavy in the bridle, inconsistent in his contact, and was tossing his head through transitions.
Nothing dramatic, just enough to know that something was missing.
The horse was fine, at least on the surface.
But when I assessed his mouth and his bit, I knew he was not comfortable.
He didn’t have enough room to comfortably accept what he was being asked to accept.
The bit was too thick for his mouth, giving him no way to soften, chew, or accept his contact.
This was not a training problem.
This was a comfort problem.
We changed to a bit that fit his mouth, giving him tongue room and balance.
Instant change.
He no longer braced through his transitions.
The contact was light and consistent.
And for the first time, he began to step underneath his body and lift, rather than fight his rider.
What happens when the bit actually fits
This is the part people don’t expect:
You feel it instantly
Steering becomes easier
Transitions feel smoother
The horse starts to lift and step under
Contact becomes lighter, not heavier
The horse feels more present and willing
It’s not magic
It’s just removing restriction
Bit fitting vs training
This is important:
Training teaches the horse how to respond
Bit fitting allows the horse to physically respond comfortably
You need both
But if the foundation is off
Training becomes harder than it needs to be
Where bodywork and Reiki come in
Here’s where everything connects
If a horse has been going in an uncomfortable bit:
Jaw tension builds
Poll restrictions develop
Neck and hyoid function are affected
The nervous system can stay in a guarded state
This is why I often combine:
Bit fitting
Bodywork
Energy work
Because we’re not just changing the equipment
We’re helping the horse reset
Work with me
If you’re questioning your horse’s bit, there’s probably a reason
I offer:
In-person bit fittings in South Carolina and Georgia
Virtual bit fittings with detailed analysis, marked-up photos, and a clear plan
Bodywork sessions to support long-term comfort and performance
And lastly Reiki both in person and virtually all over. I recently released a Reiki certification course where you can learn to heal yourself, heal your horse, and teach and certify others.
