When does a rabbit stop growing? [10+ Breeds Covered]


Rabbits are fluffy animals that grow quickly right in the first 6 months. The growth phase varies from one breed to the other based on several factors.

Let’s dive right into specifications on when different types of rabbit breeds would stop growing.

When does a rabbit stop growing?

Upon raising over 7 breeds of rabbits in the last 10 years, I have found that the growth of a rabbit is influenced by climatic condition, genetics, health condition, and diet.

Small rabbits like Netherland Dwarf, Dwarf Hotot, and Britannia Petite grow up to 3lbs in 6 months while medium breeds like American Sable, Harlequin, Belgian Hare, and English Angora grow up to 8lbs in 10 months. Large breeds including Giant Angora, Flemish Giant, and Checkered Giant grow up to 15lbs in 1.5 years.

Perhaps, the weight can vary based on the diet given at the moment. Sometimes, a crossbreed of rabbits can also end up in different growth levels. If I were asked to answer just one statement to the question, I would say 1 year.

To help you better understand this topic, I have provided a table right here to compare the size and weight of your rabbit based on the breed.

Breed Weight Duration for growth
Netherland Dwarf ~2lbs 6 months
Dwarf Hotot ~3lbs 6 months
Britannia Petite ~3lbs 6-8 months
Lionhead ~3lbs 6-8 months
Mini Holland lops ~3-4lbs 8 months
Dutch ~5lbs 6-7 months
English spot ~3-8lbs 6-12 months
American Sable ~6-8lbs 10-12 months
English Angora ~8lbs 10 months
Harlequin ~8lbs 10 months
Lilac ~6-10lbs 8-12 months
Rex ~8-10lbs 10 months
New Zealand ~9-12lbs 9 months
Giant Angora ~15lbs 1.5 years
Giant Chinchilla ~15lbs 1.5 years
Flemish Giant ~15-17lbs 1.5 years


At what age is a rabbit fully grown?

1 year. Irrespective of the rabbit breed, the growth stage hits 90% by 1 year and completes by 1.5 years.

When you nurture your rabbit with sufficient nutrition, the weight can increase even after 1.5 years making them grow in long run.

How big is a full-grown rabbit?

A fully grown rabbit lies anywhere between 8 inches and 20 inches in length and 3lbs-20lbs in weight. If you are domesticating a rabbit, you can expect the rabbit to attain 6lbs in 3-5 months.

What is the normal weight for a rabbit?

About 6 years ago, I was raising a rex rabbit which was deemed to weigh not more than 3lbs. Perhaps, rabbits are tiny and cute but I was astonished by the weight when he was 4 years of age.

He weighed around 8lbs. That was when I decided to check what the normal weight of a rabbit is. This is important because you need to maintain this weight for the rest of his/her life. Malnutrition and obesity are two zones of weight that a rabbit should never enter into.

The normal weight for a rabbit is 6lbs and a giant breed of rabbit can weigh up to 20lbs.

As we raise rabbits at home, we need to maintain the borderline of 6lbs as rabbits can size down up to 2lbs which can be life-threatening at some point.

What is the average height of a rabbit?

The average height of a rabbit is 12 inches. Based on the breed, a rabbit can be as tall as 5 inches up to 18 inches while domesticated rabbits raised at home are about 10 inches in height.

If you are raising a rabbit exclusively for rabbit shows, you may have to go with giant breeds that grow up to 18 inches and sometimes, even beyond this value.
