Do Martingales Affect Bridle Fit?
Exploring Necessity, Merits, and Alternatives
Written by Emma Harris, WOW-qualified saddle fitter and LANTRA-trained master bridle and bit fitter
Walk into any tack room and you will likely find at least one martingale hanging alongside the bridles. These pieces of equipment are so commonplace in many disciplines that riders rarely question whether they are truly necessary — or how they might be affecting their horse's comfort and the function of their bridle.
At The Fitted Horse, martingales come up regularly in bridle fitting consultations. The questions follow a familiar pattern: should I use one? Does it affect bridle fit? Is there a better option?
These are excellent questions that deserve honest answers.
What martingales do — and what they do not
The main types
Standing martingale — attaches from the girth or breastplate directly to the noseband. Prevents the horse from raising their head above a fixed point. Creates a static limitation on head carriage that cannot be adjusted during work.
Running martingale — attaches from the girth through rings on the reins to the bit. Creates downward pressure on the bit when the horse raises their head above the desired point. More dynamic than a standing martingale but still creates an indirect rein aid.
Irish martingale (Irish rings) — simply connects the two reins together with a short strap. Does not restrict head carriage. A genuine safety device that prevents reins going over the horse's head. The only martingale type we rarely question.
Bib martingale — a variation of the running martingale with leather between the forks, preventing the horse from becoming caught in them. Common in racing and polo.
Their stated purpose
Martingales are designed to prevent a horse from raising their head to a dangerous height, encourage lower head carriage, and provide additional control in fast or competitive work.
These sound reasonable. But examining what actually happens when a martingale is added to a fitted bridle reveals a more complicated picture.
How martingales affect bridle fit
This is where the practical problem lies — and it is significant.
Standing martingales
When a standing martingale is engaged and the horse attempts to raise their head, the noseband is pulled downward and often forward. A noseband that was correctly positioned two finger-widths below the projecting cheekbone may now be sitting on the soft cartilage of the nose. The headpiece is pulled forward, changing the angle at the poll and potentially creating pressure where none was intended. The bit shifts position in the mouth.
This is what we call the cascade effect. Professional bridle fitting establishes everything in the correct position for that individual horse. A standing martingale disrupts every one of those positions the moment it is engaged.
Running martingales
The impact here is different but equally significant. When a running martingale engages, it creates downward pressure on the bit that would not otherwise exist — pulling the bit into a different angle in the mouth, potentially creating unusual pressure on the bars, tongue, or palate. The direct line of communication between the rider's hand and the horse's mouth is broken, with the martingale introducing an indirect, downward force that the rider cannot control precisely.
Horses are perceptive. When they discover that raising their head triggers downward pressure from the martingale, many develop evasions: overbending, going behind the bit, or leaning on the martingale as they would lean on a strong hand. All of these evasions change how the bridle sits on the head.
The paradox
A rider invests in professional bridle fitting to ensure their horse's comfort, then adds a martingale that fundamentally alters how that carefully fitted bridle functions. The fitting work is partially undone by the very equipment added alongside it.
Are martingales actually necessary?
This is the most important question — and one that is asked far less often than it should be.
When a horse raises their head excessively, the instinct is often to add a martingale. But before doing so, it is worth asking: why is the horse raising their head in the first place?
Common reasons include:
- Bit discomfort — tongue pressure, palate pressure, bar pain, or incorrect width making any degree of contact painful
- Bridle discomfort — poll pressure from a poorly fitted headpiece, a browband that is too short, a noseband pressing on facial nerves
- Dental problems — sharp points, hooks, or wolf teeth making bit contact intolerable
- Saddle or back pain — causing the horse to hollow and raise their head to escape discomfort
- Training gaps — the horse has not yet developed the strength or understanding for genuine self-carriage
- Rider factors — heavy or inconsistent hands, balance issues, or aids that are unclear or uncomfortable to respond to
A martingale addresses none of these. It addresses the symptom — the raised head — while the cause continues unaddressed and often worsens.
We have seen this repeatedly: a horse who has been ridden in a running martingale for months or years, fitted with a correctly chosen bit and a properly adjusted bridle, suddenly works in a soft, relaxed outline with no martingale at all. Not because the horse changed, but because the source of discomfort was removed.

When martingales do have merit
A balanced view requires acknowledging the situations where martingales have a genuine case:
Safety in high-speed or unpredictable work — racing, certain phases of eventing, young horses in early training where a sudden dramatic head movement could genuinely endanger the rider. In these specific contexts, a martingale as a short-term safety measure has merit.
Specific competition requirements — some disciplines or classes traditionally require or expect them.
Genuine transitional use — as a temporary safety measure while underlying causes are being identified and addressed.
The key word in all of these is temporary. A martingale used as a permanent solution to a persistent problem is almost always masking something that deserves investigation.
The drawbacks — what is often left unsaid
Physical consequences
Restriction of natural biomechanics — horses use their head and neck as a balancing mechanism during all work, but particularly over fences and varied terrain. Restricting this natural movement causes compensatory tension through the back and hindquarters and compromises the horse's ability to use their body optimally.
Incorrect muscle development — a horse forced into a particular head position rather than developing correct carriage through training builds the wrong muscles. The underside of the neck develops disproportionately, core strength and topline development are inhibited, and genuine collection becomes physically more difficult to achieve.
Masking pain — this is the most serious concern. A horse with back pain raises their head to hollow and escape it. A martingale forces the head down. The pain continues. The horse cannot communicate it. The problem worsens. Saddle fit issues, dental problems, and physical conditions can all remain unaddressed for months or years because the symptom that might have prompted investigation is being suppressed.
Training consequences
Prevention of genuine self-carriage — true collection and correct carriage come from engagement of the hindquarters, core strength, balance, and the horse learning to carry themselves willingly. A martingale forces the head down without teaching any of these fundamentals. The horse never develops real self-carriage because the equipment does the work.
Interference with refined communication — as training progresses, communication between horse and rider becomes increasingly subtle. Running martingales create an indirect line, muddy the effect of half-halts, and reduce the rider's feel of the horse's mouth. This is counterproductive to everything that correct training works toward.
Development of new evasions — horses who are consistently restricted often find other ways to express discomfort: overbending, going behind the bit, becoming heavy in the hand, or developing tension elsewhere in the body.
Better alternatives
First — address the root cause
Before considering any equipment alternative, the most valuable step is a systematic investigation of why the horse is raising their head.
Professional bridle and bit fitting covers the equipment side — headpiece design, bit width, mouthpiece type, browband length, noseband position — all of which directly influence head carriage. Our bridle and bit fitting consultation is specifically designed to identify these factors.
Alongside that, a recent dental examination, saddle fit check, and if needed a veterinary or physiotherapy assessment will rule out physical causes. And working with a qualified trainer to assess whether there are training gaps in the horse's foundation is equally important.
In the majority of cases we see, addressing these fundamentals eliminates the behaviour that seemed to require a martingale.
Equipment alternatives
A breastplate without martingale attachment — if your concern is saddle stability or rider security rather than head carriage, a breastplate provides a neckstrap and prevents the saddle slipping without restricting the horse in any way. Hunting breastplates, elastic breastplates, and five-point breastplates all serve this function well. This is our most recommended alternative for riders who feel they need something for security.
A standalone neckstrap — a simple strap around the neck gives the rider something to grab in an emergency without any influence on head carriage or bridle fit. Inexpensive, simple, and effective.
A correctly fitted bridle with an appropriate bit — this sounds obvious, but it is the genuine solution in most cases. An anatomical headpiece with generous ear cut-outs removes poll pressure. A bit with appropriate tongue relief removes mouth discomfort. A correctly positioned noseband removes facial nerve pressure. The head comes down because the horse is comfortable, not because equipment prevents it from going up.
Groundwork and training approaches — lungeing with a Pessoa system or similar, long-reining, and pole and cavaletti work all encourage the horse to find correct carriage through developing strength and understanding, rather than through restriction. These are temporary training tools, not permanent equipment — and they teach the horse something a martingale never can.
Making the transition away from a martingale
If your horse has been ridden in a martingale for some time, a gradual transition is more successful than immediate removal.
Address the underlying causes first — bridle fit, bit fit, dental check, and any physical issues. Do this before changing anything about the martingale.
Lengthen gradually — over two to four weeks, progressively lengthen the martingale adjustment so it becomes less restrictive with each ride. The horse remains familiar with the equipment but begins to discover freedom of movement.
Remove it — once the adjustment is at maximum length and effectively non-functional, remove it entirely. Continue monitoring the response and supporting the horse's training during the adjustment period.
Be patient — horses who have been restricted for a long time sometimes need a period to learn to balance themselves. This is a training task, not a reason to put the martingale back on.
Key takeaways
✔ Martingales affect bridle fit directly — a standing martingale displaces a correctly fitted noseband and headpiece the moment it is engaged
✔ Head raising is a communication — it almost always has a cause, none of which a martingale addresses
✔ Most martingale use is symptomatic management of a problem that deserves investigation
✔ A breastplate provides rider security without any restriction on head carriage or bridle fit
✔ When equipment fits correctly and training is appropriate, most horses have no need for a martingale
✔ If a martingale has been necessary for months or years, ask what it has been silencing rather than assuming it is simply needed
