A 13 vs 15 inch beagle comes down to height. A 13 inch beagle stands 13 inches or under at the shoulder and weighs under 20 lb. A 15 inch beagle stands over 13 up to 15 inches and weighs 20 to 30 lb.
Both are the same breed. The American Kennel Club (AKC) splits them into two size varieties for the show ring.
13 vs 15 Inch Beagle Size Differences
A 13 inch beagle and a 15 inch beagle are two height classes of one breed, not two different breeds. The AKC sets the line at 13 inches, measured at the withers (the top of the shoulders).

| Body length | About 20 in | Up to 24–25 in |

AKC vs UK Beagle Size Standards
The AKC disqualifies any beagle over 15 inches in the show ring.
The UK Kennel Club uses one range instead: 13 to 16 inches. So a 16-inch beagle can be correct in Britain but oversized in an American show. For a pet, this makes no difference.
13 vs 15 Inch Beagle Height
How to Measure Beagle Height at the Withers
Measure from the floor to the top of the shoulder blades. Do not include the head or neck.
- Stand your dog on a flat, hard floor.
- Make sure all four feet are square and the head is level.
- Place a flat book across the withers, touching the wall.
- Mark the wall, then measure from the floor to the mark.
Measure twice. Beagles wiggle.
Is My Beagle a 13 or 15 Inch Beagle?
- 13 inches or less: 13 inch variety
- Over 13 up to 15 inches: 15 inch variety
- Over 15 inches: oversized for AKC shows, but still a healthy pet
A beagle taller than 15 inches is not a problem for pet life. It only matters for the show ring.
13 vs 15 Inch Beagle Weight and Growth Chart
| Age | 13 Inch Beagle | 15 Inch Beagle |

When Do 13 and 15 Inch Beagles Stop Growing?
Beagles reach full height at about 8 to 12 months. After that, they fill out with muscle until about 18 months.
Weight gained after 18 months is usually extra fat, not growth.
Male vs Female Beagle Size
Male and female beagles share the same height classes. Males tend to be a little heavier, with a broader chest. Females tend to be lighter and more refined.
Both can be 13 inch or 15 inch beagles.
