This document provides information on horse conformation analysis. It begins with an anatomy diagram labeling horse parts. It then discusses the BSMQTT system of conformation analysis: balance, structure, muscling, quality, type, and travel. The summary focuses on key aspects of balance, structure, and body conformation.
The ideal horse is balanced with equal thirds between the shoulder, body, and hindquarters. Structure is important, with an emphasis on a long sloping shoulder, long neck, straight legs, and sloping pasterns. For body conformation, prominent withers, a deep wide chest, and a long back are desirable traits.

3. Conform ation analysis is the system atic com parison
of one horse to another, and all horses to an ideal
type for the breed or athletic pu rpose. One confor -
m ation analysis system is known as BSMQTT:
balance, stru ctu re, m u scling, qu ality, type, and
travel. Start you r conform ation analysis by becom -
ing fam iliar with the parts of the horse (Figu re 1).
BALANCE
The ideal light horse will be balanced, as determ ined
by dividing it into three sections. Draw im aginary
lin es separatin g the shou lder area, body, and
hindqu arters. A horse can be divided equ ally only if
it h as a lon g, sloping shou lder; short back with a
corresponding long u nderline; and a long hip
(Figu re 1). The head and neck shou ld not look
excessively large or sm all when com pared with the
rest of th e body. Th e legs sh ou ld be abou t th e sam e
len gth as th e h eart girth.
STRUCTURE
HEAD & NECK
The head and neck are im portant in determ ining the
athletic ability of the horse. A su pple horse u ses its
head and neck as a ru dder and stabilizer. Free head
and neck m ovem ent has a profou nd influ ence on
th e horse’s way of going. For a horse to be well
balanced, the neck shou ld be long and lean with the
head size in proportion to the rest of the body.
Hea d
Th e h ead sh ou ld follow th e type of th e breed, an d
be fin ely ch iseled with good defin ition of th e bon y
fram ework.
The head should be triangular when viewed from the
side; shou ld have large powerful jaws, and taper to the
mu zzle. The profile should be a straight or slightly
dished face as opposed to an arched or Roman nose.
As viewed from the front, the forehead should be wide
between the eyes, tapering to the muzzle.
Neck
The head shou ld attach to the neck in a m anner
th at provides am ple m ovem ent and flexion withou t
im pairin g of th e air passages. The throatlatch
shou ld be clean, trim , well defined and capable of

great flexion. A short, thick neck is often correlated
with a thick, u nyielding throatlatch, incapable of
flexion. In som e breeds, a slight arch or crest on top
of the neck is desirable, bu t an excessive crest, th ick
u pper neck, or broken crest (lop neck) are u ndesir -
able becau se they can interfere with flexibility. A
stallion shou ld carry m ore crest than a m are. A
thick “stu ddy” neck on a m are is u su ally associated
with a lack of fem inine appearance. The u n derlin e of
the neck shou ld be straight and attach high on th e
shou lder giving the appearance of a vertical chest.
A con cave n eck, accom pan ied by a depression in
fron t of th e with ers, is often accom pan ied by a

wh ich absorb con cu ssion , an d (2) th e straigh tn ess
an d tru en ess of lim bs, so th at n o on e segm en t
receives u n u su al wear.
Forequ arters con cu ssion is absorbed by:
• th e u n iqu e m u scu lar attach m en t of th e forelim b
to th e body;
• th e slopin g sh ou lder blade (scapu la) an d, con se-
qu en tly, th e an gle form ed between th e sh ou lder
blade an d h u m eru s (arm );
• th e an gle between th e h u m eru s an d forearm ;
• th e sm all bon es an d ten don s su rrou n din g th e
carpu s;
• th e slopin g sprin gy pastern ;
• th e expan sion an d absorption m ech an ism of th e

Should er
The shou lder shou ld be long, sloping, and mu scu lar.
It shou ld extend well into the back. The longer the
shou lder the greater the area for attachment of the
mu scles that tie the forelimb to the vertebral colu mn.
The shou lder shou ld slope well into the back. This
decreases the angle between the scapu la and
hu m eru s and redu ces concu ssion. A sloping shou l-
der also provides for free forward m otion of the lim b
by allowing m axim u m length of stride. A short
straight shou lder redu ces stride and increases
im pact with th e grou nd. A straight shou lder is often
associated with a short, straight pastern that fu rther
shortens the stride and increases concu ssion.
Ar m
Th e h u m eru s or arm exten ds from poin t of sh ou l-
der to th e elbow join t an d sh ou ld be m oderately
lon g. Hu m eru s len gth is in tegral to th e len gth of
th e stride. An excessively sh ort arm , with its
accom pan yin g sh ort m u scles, will n ot advan ce th e
forearm en ou gh an d th e stride will be sh orten ed.
On th e oth er h an d, a lon g arm cau ses excessive
wear to th e sh ou lder m u scles.
Th e len gth of arm sh ou ld be in proportion to th e
len gth of th e sh ou lder an d forearm . Th e len gth of
th e arm determ in es wh eth er legs are set forward or
back u n der th e body. Th e legs sh ou ld be set well
forward.
A lon g sh ou lder, sh ort arm , plu s lon g forearm an d
sh ort can n on allows m axim u m stride exten sion .
Forea rm
Forelegs shou ld be straight and perpendicu lar when
viewed from all directions. The forearm is form ed by
th e fu sion of two bones, the radiu s and the u lna,
and extends from the elbow to the knee (Figu re 2).
It shou ld be long and well m u scled. Forearm length
is im portant in determ ining stride length.

There are eight carpal bones arranged in two rows.
Their fu nction is to bear weight and su pport the body.

Pa s t ern
Both slope and length of pastern help determine
smoothness, spring, and stride length. A pastern
which is too long and sloping (coon footed) cau ses
weakness becau se it pu ts u ndu e strain on the
tendons, sesamoid bones, and su spensory ligament.
On the other hand, a short u pright pastern increases
concu ssion and trau ma to foot and fetlock (Figu re 5).

6. BODY
Th e body is com posed of th e with ers, th orax, an d
back. Its con form ation affects balan ce, capacity
an d ath letic poten tial.
Wit hers
Th e with ers is th e h igh poin t of th e h orse’s back
an d is located at th e base of th e n eck between th e
sh ou lder blades (Figu re 1).
Withers shou ld be prom inent and capable of holding
a saddle. It sh ou ld be m u scu lar an d well defin ed at
th e top an d exten d well in to th e back. Th e with ers
serves as a fu lcru m over wh ich a ligam en t attach ed
to th e vertebrae in th e back an d n eck acts to h elp
raise an d lower th e h ead an d n eck.
Horses with low, rou n d, th ick with ers often h ave
rollin g gaits an d h eavy fron t en ds. A flat, m u tton
with ers will n ot h old th e saddle in place. Wh en th e
withers is prominent, the ligaments and mu scles
that attach the neck to the thorax move freely and
the horse exhibits greater flexibility, coordination,
and energy in its movement. High, sloping withers
with long sloping shou lders increases the length of
mu scles in the front end and resu lts in freer action.
It sh ou ld be em ph asized th at a prom in en t with ers
sh ou ld be accom pan ied by m u sclin g becau se a
th in , over -prom in en t with ers is often ru bbed by th e
saddle an d resu lts in stiffn ess an d soren ess.
Thora x
Wh en viewed from th e fron t, th e ch est sh ou ld be
wide an d deep. A n arrow ch est in dicates lack of
m u sclin g an d area for th e h eart an d lu n gs. How-
ever, an excessively wide ch est forces th e legs ou t,
so th e gait m ay be rollin g an d labored.
From th e side, th e th orax sh ou ld be deep. Th is
region con tain s lu n gs an d h eart an d m u st sh ow
capacity. Th e rib cage provides a base for attach in g
forelim b m u scles as well as protectin g th e vital
organ s. Wh en th e ribs are arch ed an d project
backward, it is possible for th e h orse to h ave a
lon g, deep ch est an d u n derlin e an d still h ave a
sh ort straigh t, stron g back (Figu re 1).
Sh ort, flat, straigh t ribs decrease th e lu n g area of
th e h orse an d redu ce ath letic poten tial. Th ese
h orses are term ed slab-sided.
Ba ck
Th e back exten ds from with ers to loin or last rib
(Figu re 1). It sh ou ld be sh ort, straigh t, stron g an d
m u scu lar. Avoid a saggin g or swaybacked h orse.
Man y lon g-backed h orses becom e swayback with
age if n ot properly con dition ed.

7. HINDQUARTERS
The conform ation of the hindqu arters (Figu re 8) will
have a dram atic effect on athletic ability becau se of
th eir im portance in propelling the horse forward.
Croup
Th e slope of th e crou p h as a stron g correlation
with th e h orse’s fu n ction . Lon g distan ce or en du r -
an ce h orses h ave a level crou p. Sh ort distan ce,
speed h orses h ave a sligh tly slopin g crou p. A very
sh ort, steep crou p is associated with straigh t h in d
legs (post-legged; Figu re 9g) an d predisposes th e
h orse to con cu ssion in ju ry in th e h ock.
Fem ur
Th e fem u r sh ou ld be sh ort with th e stifle poin ted
sligh tly ou tward so th ere will be a fu ll ran ge of
m ovem en t for th e h in d legs.
If the femur is carried too far to the rear, the legs are
carried too far backward. This is called “camped out”
(Figure 9f). If it is carried too far forward, the legs are
brought under the body. This is called “camped under”
or “sickle-hocked” (Figure 9e). When a horse is
camped-under the angle of the hocks place undue
strain on the hind legs (particularly the planter liga-
ments), and can lead to unsoundness called “curb.”
Tibia
Th e ideal h orse h as a lon g tibia (gaskin ) an d sh ort
can n on with low-set h ocks. Th is allows th e h orse
to work off of its h ocks an d provides th e m axim u m
stride exten sion .
Hock
If the hock is raised and the tibia shortened, cu sh-
ion is redu ced and perform ance can be lim ited.
Th e h ock sh ou ld be clean , h avin g n o soft tissu e
swellin g or bon y projection s. It sh ou ld be well-
defin ed an d powerfu l.
Th e an gle of th is join t sh ou ld allow th e h in d leg to

am ou n t of stress to th is colu m n of bon es.
