Equi-Calc™
What Is Equi-Calc™?

A patented calculator using girth,
height and length measurements
estimates your horse's weight more
accurately than any other method
currently available.
Why Do You Need To
Know Your Horse’s
Weight?

It is critical for horse owners,
veterinarians, trainers, and others
involved in the care and management
of the horse to accurately establish a
horse’s weight.

An accurate weight is required for
medication dosing, nutrition and
feeding requirements, training
purposes, and general health
monitoring of the horse.

Accurate equine weight is vital for
administration of wormers and other
medications.  Under-dosing of
wormers may possibly result in
parasite resistance and chronic health
problems, while overdosing can result
in colic and other health issues.

Why Is Equi-Calc™ The
Best Choice?

Digital scales are the most accurate
method for obtaining a horse’s
weight, but they are not readily
available.

Visual estimation results in
substantial errors even among the
most experienced veterinarians and
horsemen.

Girth weight tapes take only one
proportion into consideration in
predicting a horse’s weight resulting
in reduced accuracy, especially on
horses that are not typically
proportioned.

The patented formula in Equi-Calc™
uses three measurements, girth,
height, and length of a horse to
predict weight, allowing for a more
accurate estimate.

To determine your horse’s weight
using Equi-Calc™, simply take the
three measurements, enter them into
the calculator, and the result is
displayed immediately.
Since your horse is so important to
you, shouldn’t you be using Equi-
Calc™?

How Equi-Calc™ Works:
U.S. Patent No. 6,820,033
The girth measurement is obtained by
taking a measurement in inches
around the heart girth of the horse
with the measuring tape snug against
the horse, following respiratory
expiration.  The tape is placed directly
behind the elbows, the ends of the
tape are overlapped, and the
indicated girth distance is recorded.
Take Girth Measurement:
Take Height Measurement:
The height measurement is obtained
by taking the distance in inches from
the ground to the top of the withers.
Take Length Measurement:
The length measurement is obtained
by taking the distance in inches from
the point of the shoulder to the point
of the buttocks in a straight line.
Estimate Weight Using Equi-Calc™:
Once the three measurements are
obtained, simply enter them into
Equi-Calc™ and the weight estimate is
immediately displayed!
