Beagle Size and Weight Guide: How Big Do Beagles Get?

One of the most common questions from prospective Beagle owners is: how big does a Beagle get? The answer affects whether a Beagle suits your home, your lifestyle, and even your car. This guide covers the two official Beagle sizes, how growth progresses from puppy to adult, typical weights, and how to tell if your Beagle’s weight is healthy.

Two Official Beagle Sizes

The Beagle breed standard recognises two size varieties, measured at the shoulder (withers). In Europe, the FCI standard is used:

Under 33 cm (approximately 13 inches): The smaller variety, typically weighing 8-10 kg as an adult
33-40 cm (approximately 13-16 inches): The standard variety, typically weighing 10-14 kg as an adult

Our full guide to the types of Beagles explains the differences in detail. Importantly, both sizes share the same temperament: curious, friendly, determined, and food-motivated.

Beagle Growth Chart -- From Puppy to Adult

Beagles grow quickly in the first six months and reach their full adult size between 12 and 18 months. A typical growth timeline:

8 weeks: 2-3 kg — small and fragile, needs gentle handling
3 months: 4-5 kg — growing rapidly, appetite increases significantly
6 months: 7-9 kg — about 75% of adult weight; growth begins to slow
12 months: Near adult weight — 9-13 kg depending on size variety and sex
18 months: Fully physically mature; muscle development continues to around 2 years

Males tend to be slightly larger than females within the same litter. See our male vs female Beagle guide for more detail.

Is My Beagle a Healthy Weight?

Beagles are one of the breeds most prone to obesity. The best way to check is the rib test:

Run your hands along your Beagle’s ribcage — you should feel each rib with light pressure, but not see them from a distance
Looking from above, there should be a gentle waist visible behind the ribs
From the side, the belly should tuck up slightly from chest to hind legs

If you cannot feel the ribs without firm pressure, your Beagle is likely overweight. Our Beagle weight management guide provides a complete action plan.

Does Beagle Size Affect Apartment Suitability?

Both Beagle sizes can live in apartments — but their exercise needs do not change with size. A smaller Beagle in a flat still needs 1-1.5 hours of exercise daily. See our Beagle apartment living guide for city-living advice.
