You’ve seen the photos. Those grainy, slightly blurry images of a person struggling to hold a rabbit that looks like it could go three rounds with a Golden Retriever. You probably thought it was Photoshop. Honestly, I did too the first time I saw it.
But it’s real.
The biggest bunny rabbit in the world isn’t just a fluke of nature; it’s a specific breed with a history that’s actually kinda wild. When we talk about these massive creatures, we’re usually talking about the Continental Giant or its cousin, the Flemish Giant. These aren't just "big" bunnies. They are biological anomalies that eat more than some humans and can literally kick a hole through a drywall.
The King of the Hutch: Darius and the 4-Foot Legacy
If you want to get technical about who the actual heavyweight champion is, you have to talk about Darius. Darius was a Continental Giant from the UK who officially took the Guinness World Record for the longest rabbit.
How long? 4 feet 3 inches.
To put that in perspective, that’s about the height of an average nine-year-old child. Imagine a rabbit stretching out on your sofa and taking up the entire thing. That was Darius. He weighed around 50 pounds.
Now, here is where it gets a bit weird. Darius didn't just appear out of nowhere. His owner, Annette Edwards, basically has a dynasty of giant rabbits. Darius took the title from his mother, Alice, who took it from her father, Roberto. It’s like a royal family, but with more hay and much longer ears.
Sadly, the story of the current record holder is a bit of a mystery. In 2021, Darius was actually stolen from his enclosure in Worcestershire. Despite a massive reward and a global search, he hasn't been found. Since then, the title of the "world's biggest" has been in a bit of a flux, with descendants like Jeff (Darius's son) reportedly pushing the 4-foot-4-inch mark.

It's Not Just About the Length
When people search for the biggest bunny rabbit in the world, they usually focus on how long they are. But the weight is the part that really shocks you.
A standard pet rabbit might weigh 3 or 4 pounds. A "giant" breed starts at 13 pounds and just keeps going. Most Continental Giants sit comfortably around 16 to 25 pounds, but the record breakers like Ralph (another UK legend) reached 55 pounds.
Basically, you aren't carrying these guys in a little plastic pet carrier from the grocery store. You’re using a dog crate. Or a wheelbarrow.
Why do they get so big?
It’s mostly selective breeding. Hundreds of years ago, people in Belgium weren't breeding these guys to be cute pets. They were breeding them for meat and fur. They wanted the most "rabbit" per rabbit. Eventually, the breed standards for the Flemish Giant were stabilized in the late 1800s, and breeders realized these "gentle giants" had personalities that were way too good to end up on a dinner plate.
What It’s Actually Like Living With a Giant
You might be thinking, "I want one."
Hold on.

Having the biggest bunny rabbit in the world in your house is less like having a pet and more like having a very quiet, very hungry roommate who refuses to pay rent.
First, the food. We’re talking about 12 carrots, two bowls of specialized rabbit mix, three apples, and a literal bale of hay every week. Annette Edwards famously noted that her giants go through about £5,000 worth of food a year. That’s a decent used car every couple of years, just in carrots.
Then there’s the "rabbit-proofing." A normal bunny might chew a phone charger. A Continental Giant can chew through a table leg. If they get bored, your baseboards are toast.
The "Dog-Like" Personality
The weirdest thing about these massive rabbits is that they don't really act like rabbits. They don't usually do that frantic, twitchy "prey animal" thing. They’re chill.
They’re often called "dog-rabbits" because:
- They come when called (usually).
- They love sitting on the couch to watch TV.
- They can be litter-trained just like a cat.
- They actually seek out human affection instead of just tolerating it.
The Health Reality Nobody Tells You
There is a downside to being the biggest bunny rabbit in the world.
Biology has a limit. Just like giant dog breeds (think Great Danes), these massive rabbits don't live very long. While a small house rabbit might live 10 to 12 years, a Continental Giant is doing well if it reaches 5 or 6.
Their hearts have to work incredibly hard to pump blood through those massive bodies. They also get sore joints. If they jump down from a high sofa, they can actually break their own legs because their bones are relatively fragile compared to their massive muscle mass.
It’s a bit of a tragic trade-off. You get this incredible, intelligent, massive companion, but you don't get them for very long.
The Best Giant Breeds to Look For
If you aren't trying to break a Guinness World Record but you still want a "big" bunny, you have options. You don't necessarily need a 50-pounder to get the experience.
- Flemish Giant: The "Universal Rabbit." They are the most common and generally the friendliest.
- British Giant: A bit smaller (around 12–15 lbs) and very laid back.
- Giant Chinchilla: Bred specifically for their size and incredibly soft fur.
- French Lop: If you want the size but with floppy ears that drag on the floor.
How to Prepare for Your Own Giant
If you’re serious about bringing home one of these beasts, don't buy a cage. Just don't. No cage sold in a pet store is big enough for a Continental or Flemish Giant.
Most owners use a "bunny room" or a large dog pen. They need enough space to take three massive hops in a row. For a rabbit that’s 4 feet long, that means you need a run that's at least 12 to 15 feet long.
Watch the floors. These rabbits have no pads on their feet, just fur. On hardwood or tile, they’re like a cartoon character on ice. They can easily slip and dislocate a hip. You need rugs. Lots of rugs.
Actionable Steps for Future Giant Rabbit Owners
Before you go hunting for a breeder, do these three things:

- Find an "Exotic" Vet: Your local vet who sees cats and dogs might not know what to do with a 20-pound rabbit. You need someone who understands rabbit-specific GI stasis and cardiac issues.
- Budget for the Hay: Don't buy those tiny bags at the pet store. Find a local farmer and buy a full bale of Timothy hay. It’s the only way to keep them fed without going bankrupt.
- Reinforce Your House: Get plastic cord protectors for every single wire in your home. Even the ones you think are out of reach. They can stand on their hind legs and reach 3 feet up easily.
Owning the biggest bunny rabbit in the world—or even just a "regular" 20-pound giant—is a massive commitment. Literally. But if you have the space and the budget for 2,000 carrots a year, there isn't a pet in the world that’s quite as rewarding.
