Saddle Fit
Whoever that
brave soul was who first decided to climb on a horse’s back probably
impressed all of his friends and neighbors by how much further he could
go and how quickly he could get there. But very soon he found that for long
distances that it wasn’t very comfortable for either him or the horse.
In bareback riding, which is a great tool for developing balance, all of
the rider’s weight is concentrated in a very small area of the horse’s
back. The main job of a saddle is to spread the rider’s weight out
over the length of the ribcage which lowers the pounds per square inch to
an acceptable level for the horse. The other thing a saddle must do is to
keep any pressure off of the horse’s spine.
While I will be referring to the Western tree, the basic concepts apply to the
English saddle as well but instead of using the bars of the Western tree
to spread out the rider’s weight the English saddle uses panels stuffed
with wool or foam. Four things to keep in mind are that the heavier the rider,
the more often they ride, the longer they ride and the harder they ride,
the more critical it is to have a saddle that fits. A one hundred and ten
pound gal who rides an hour once a week and only walks her horse can get
away with a terrible fitting saddle and possibly never see a problem. A two
hundred pound guy who rides twenty hours a week and does a lot of cantering
and trotting does not have much room for error when it come to a good fit. Two dimensions on
the horse’s back must be addressed for proper
saddle fit. First, the front to back curvature of the saddle tree, referred
to as ‘rock’ or ‘rocker’, must match that of
the horse’s ribcage. If you picture the bottom rails on a rocking
chair you can see that too much rock (1) will put excessive pressure
into a small area of the horse’s back, and too little rock (2)
will create pressure at the front and rear of the saddle with very little
in between. This would be called ‘bridging’. A saddle will
also bridge if the gullet is too narrow and won’t allow the saddle
to sit down properly in front. Secondly, the change in angle of the bars
from the front of the tree to the back, referred to as the’ twist’,
must also match the horse’s ribcage. If you look at the bottom
of a tree you will see that the angle of the bars are steeper in the
front and gradually flatten out towards the back. Too much or too little
twist can cause problems wherever it doesn’t match the horse’s
ribcage.
When considering saddle fit you would like to see maximum contact in
the middle two thirds (03) of the saddle with contact tapering off at
the front and rear
of the bars. If the front of the bars don’t have enough ‘flare’ in
them, there won’t be enough room for the shoulder to operate comfortably
or for the horse to move his neck laterally. Gaited horses, with their more
animated shoulder motion, need even more flare than other breeds. In the rear
of the bars there must be enough flare for the horse’s hips to alternately
rise and fall.
Through the years
the bars of the saddle tree have been loosely classified by various
names. Some
of the more popular are semi-Quarter Horse, Quarter
Horse, and Arab-Morgan trees. If we divide up different horse’s
ribcages into narrow, medium and wide classifications, Semi-Quarter Horse
barred trees would be a starting point for your narrower horses, Quarter
Horse barred trees would be for the medium range and Arab-Morgan barred
trees for your wider horses. That being said, there is absolutely no
standard between tree manufacturers. If we took three Quarter Horse barred
trees from three different tree manufacturers there would be differences
not only in gullet height and width but also in the rock and twist. That’s
why one saddle maker’s full Quarter Horse barred tree might work
fine and then you switch to another brand and you end up with a sore
horse.
Being a custom saddler,
one of the things we hear all the time is “I
have a hard to fit horse.” Generally, these people have tried three
to five different saddles from different manufacturers and haven’t
had any luck with any of them. Production line or tack shop type saddles
are built on averages. “The “average” narrow horse’s
back needs a gullet that is so wide and so high and needs this much rock
and this much twist.” But what happens when a horse has what I
call a combination back? Maybe he is narrow in the front but the twist
flattens out more than the “average” narrow horse. Horses
are just like people. If we take ten men who are 6’ tall and weigh
180 lbs, five of them would look fine in an off the rack suit. The other
five would have varying levels of success because they aren’t “average” enough.
A couple of them might have to have a tailored suit custom made for them.
Different measuring
techniques have been used over the years. If you can’t take your horse to the tack shop to try different saddles
or you are having a custom saddle made the absolute minimum you should
do is get a wither tracing. You can take something flexible like wire
or buy a drafting tool called a Flexible Curve and mold it over the horse’s
back about two inches behind the shoulder blade and then trace it on
a piece of stiff paper or cardboard. You can then try your template in
the gullets of different saddles or send it to the saddle maker and you
will be able at least get a saddle with the right type of tree in it.
If your horse falls into the realm of average for that width tree you
shouldn’t have any problems. For long distance fitting there is
also a device called a Saddle Tech gauge. If there is a technician in
your area they can come and take measurements and send them to a saddler
and if he also has one of the gauges he can recreate certain measurements
in his shop. (04)
One of the most creative ideas that has come along is the EQUImeasure
Kit. It is a flat sheet of thermal plastic that you slide into the oven
and heat
up until pliable and then mold to your horse’s back. You can bring it
to the local tack shop and try the mold in different saddles to see which is
the closest, or, you can send the EQUImeasure to any custom saddler and it’s
like having the actual horse’s ribcage right there in the shop.
When evaluating
saddle fit I have come to believe that it can be difficult for most
people to
visually inspect the fit themselves. One of the other
uses for the EQUImeasure form is for evaluating fit. If you place your
saddle on the ground on its pommel and set your EQUImeasure into the
bottom of the saddle (05), you can look to see how much contact you are
getting. This is far easier for most people than trying to do this with
the saddle on the horse. Once again, you are looking for good contact
the middle two-thirds of the saddle with contact tapering off slightly
at the front and back. If the shape of the bottom of the saddle doesn’t
match the shape of the form, you’re headed for trouble.
When people talk
about how well a saddle fits usually the first thing I usually hear
is “Check the sweat pattern”.
(06) The theory says that if you go for a ride and get your horse good
and sweated up,
when you remove the saddle, you should see a nice even sweat pattern
under the saddle that reassembles the bars of the tree. Any dry areas
would indicate that the pressure was so great that it shut down the sweat
glands and that the smaller the dry area the higher the pressure. The
problem is that with all the advancements in technology your better pads
are designed to wick away moisture or to allow air to circulate under
the saddle to keep the horse cooler, so you might get dry spots only
because the pad is doing what it is designed to do not because of excessive
pressure.
Dry spots to me
are only a call to attention. After every ride, as soon as I remove
my saddle,
I take a look at the sweat pattern and if
I see dry areas I’ll run my hand lightly over that area to see
if there is any tenderness. If Happy Jack, my horse, doesn’t try
to duck away from my touch, I’m not going to lose any sleep over
it. If the area is tender or shows swelling then I know there is a problem.
Last year, about halfway through the summer, even though I was getting
perfect sweat patterns after our rides, Happy Jack, who is Chestnut,
started to show two or three white hairs on each side of his back right
behind the shoulder blades. White hairs on your colored horses are caused
by the cells of the hair follicle dying out because of too much pressure
(07). If something is done right away, most of the time the discoloration
will go away, but if you wait too long it may remain for the life of
the animal. In this case I was getting a perfect sweat pattern but there
was still too much pressure there. Moral of the story: Sweat patterns
can indicate an area to keep an eye on but can be misleading taken on
their own.
If visually your
saddle looks good, the next best indicator of proper fit is your horse.
How is his
attitude? If your horse is in pain, nine
times out of ten, he’ll let you know. Is he tender to touch? Is
there any swelling? Is hair being rubbed off? Is there any discoloration?
The signs are often there, if you’re looking!
So your saddle doesn’t fit quite right, is there anything you
can do? Maybe, maybe not. You might be able to do some creative padding
but if the tree is so far off because of a combination of problems, (too
wide in the gullet or not wide enough, too much rock or too little, not
enough twist or too much), it might be time to consider a different saddle.
Simpler problems can sometimes be addressed with padding. The rule of
thumb is to pad away from the pressure. I’ll illustrate this concept
with a few examples.
If you had a saddle
that was too tight in the gullet area right behind the shoulder blades,
you wouldn’t want to add an additional or
a thicker pad the entire length of the saddle. If you had a pair of shoes
that were too tight, putting on another pair of socks would make it worse
not better. The fix would be to add additional padding starting right
behind the area that was too tight, effectively lifting the saddle up
off the tight area (08)’. The opposite scenario would be a gullet
that was too wide. In this situation using a shim type pad only in the
front gullet area would be the fix (09).
Another common problem is a saddle that bridges. The saddle that bridges
has contact in the front and the back with little or no contact in the
middle. In this situation adding additional padding in the middle only
would be the fix (10). You would have to experiment with different thicknesses
and different length padding depending on the severity of the situation.
Keep in mind that the ideal situation is a saddle built on a tree that
fits the horse. But if getting a different saddle is not an option, this
is something you can experiment with.
A couple of thoughts
on the way saddles are rigged. If you took half the distance from the
cantle
to the pommel or swell, and the rigging
was hung from that point, it would be called ‘center-fire rigging’ or
half rigging. Three quarter rigging would be three quarters of the distance
from the cantle to the pommel. Seven eighths rigging would be seven eighths
of the distance and full rigging would be with the rigging hung straight
down from the pommel (11). The majority of saddles are built with three
quarter or seven eighths rigging. On saddles that are rigged seven eighths
or full, I recommend snugging up the flank cinch so you don’t have
to tighten the front cinch so much.
I have seen saddles that fit the horse perfectly but the horse was
getting the tell tale white spots behind the shoulder just because full
and sometimes seven eighths rigging pulls down so hard in the front of
the saddle that it lifts the back up off the horse and then when the
rider sits in the saddle, his weight pushes the saddle back down in back.
At this point, the saddle becomes a crowbar and puts even more pressure
in the front.
The last thing I
would like to address is the rider’s responsibility
to the horse. A saddle can also fit a horse perfectly and still sore
a horse just because the rider is so out of balance. There are two parts
to the riders balance, longitudinal (front to back) and lateral (side
to side). For a saddle to do its job correctly the rider needs to be
as close to the center of the saddle front to back as well as side to
side. We’ll cover longitudinal balance first.
One of the worse
offenses I see is a rider who sticks his feet out in front of himself
and pushes
his weight to the back of the seat. It’s
as if he were sitting in a recliner. Instead of the saddle dispersing
the rider’s weight half to the front and half to the rear; it loads
more weight in back with little in front. (12) Some people are so out
of balance this way that they can put twice as much weight in back as
they do in front. No matter how good a saddle fits, the horse is going
to get sore right under the rear ends of the bars on each side.
Many Endurance and
Competitive Trail riders, who are doing long distance events, will ‘two point’ (stand
in their stirrups) or post to relieve fatigue. If their stirrups are
forward hung instead of in
a centered, or balanced, or Dressage position or whatever you want to
call it, they put too much pressure in the front of the saddle which
results in a sore horse right behind the shoulder blades. You want to
be balanced over your stirrups with your legs underneath you, not out
in front of you. Ideally your ankle, hip, shoulder and ear should be
in vertical alignment. You should be able to stand up without having
to throw yourself forwards to get over the stirrups.
The only reason
to shift your weight forward is because of speed. As you increase speed,
your
weight should move forward accordingly. Without
getting into a physics lesson here the best illustration is to picture
balancing a broomstick on your finger. If you want to walk forwards,
the broomstick has to lean out ahead of you or it will fall backwards.
The faster you go, the more the broomstick needs to lean forwards. This
is described as moving with the action of the horse. If you don’t
adjust your weight forwards as the horse picks up speed, you end up behind
the action which makes it harder for your horse to work underneath you.
When you are out
of balance laterally, you end up with more weight on one side of the
horse’s back than the other. (13) When we see
a horse with a problem on one side of the back and not the other, the
first thing we check is to see that the length of the stirrups is the
same. Just because you have each of the leathers in the same hole on
each side doesn’t mean that they are level. Leather stretches.
Synthetic materials stretch. They have to be even or the shorter one
will pull the saddle to that side putting pressure on the opposite side
of the back as the stirrups seek to be level.
Another problem
is that because we are ‘right handed’ or
we kick a ball with or left leg or we pitch hay this way or that way
our bodies become out of balance. We end up with stronger muscles on
one side than the other. Many people who are severely out of balance
will collapse one side of their body which tilts the pelvic girdle the
opposite way resulting in more weight on one side of the horse’s
back than the other. Just because we put a saddle on our horse, it doesn’t
relieve us of the responsibility of staying in the center of the saddle
with good posture.
Before buying a
saddle from a tack shop or a custom saddler there are a few questions
I would like
to have answered first. How are they going
to fit your horse? If all they need to know is what breed horse you have,
that would be the end of the conversation for me. The minimum would be
a wither tracing. Next, can any adjustments be made if something is a
little off? If you’ve already had problems with other generic fit
saddles, this could be an issue. What is the fit guarantee and return
policy? Make sure within the trial period that you can go on two or three
rides where you are in the saddle for at least a couple of hours. If
you don’t have the time, then wait until you do. The worse possible
scenario would be finding out a few weeks after the trial period is over
that you have a sore horse and you’re stuck with a saddle that
doesn’t fit.
Although I have only scratched the surface of the topic I hope that
I have given you enough information so that you can assess your current
fit or be able to confidently talk to a tack shop sales person or custom
saddler and be able to get a saddle that will keep your horse comfortable.
