Owner Mini Pig Size Classifications

When shopping for a mini pig sizing can be confusing. Pigs come in many shapes and sizes, as well as different breeds. These shapes and sizes are often associated with a label in advertising, micro, teacup, nano, pixie, etc. The AMPA sizes pigs based on height and age, not label, to avoid confusion.  The goal is that advertising labels will be eliminated with time and through education. All registered pigs will have a size classification based on the measurements and a code for representation of maturity or age.

Height Classification Chart and Registration Code

*Measurements of height are to be taken from ground to top of front shoulder.*

Mini Category 1: 14 inches tall and under
Registration code: MC1
Mini Category 2: Over 14 inches tall up to 16 inches tall
Registration code: MC2
Mini Category 3: Over 16 inches tall up to 18 inches tall
Registration code: MC3
Mini Category 4: Over 18 inches tall up to 20 inches tall
Registration code: MC4

Age Classifications

J = Juvenile pigs under 16 months of age.
A = Adolescent pigs 16 months to 5 years of age.
M = Mature adult pigs 5 years or older.
  • The age, height, and body length of the parent pigs is the best indicator for adult size no matter what label or breed name is used to describe that individual piglet.
  • A parent pig that is 2 years or older will give you a more accurate expectation of size on any piglet.
  • Pigs grow and develop over time, most reaching skeletal maturity or adult height by 5 years of age.
  • We encourage all buyers if at all possible to see parent pigs in person. If you can’t see them in person check your local area for other breeders and owners of similarly sized pigs to help give you a better idea of what to expect.
