If you’ve ever looked at In-N-Out’s secret menu, you’ve probably seen something called the 3x3 and 4x4. These burgers aren’t listed on the regular menu, but die-hard fans know they exist.
But what exactly is the difference between a 3x3 and a 4x4? Is it just more meat and cheese, or is there something else that makes them stand out? I’ve had both, and trust me—there’s a big difference when you stack up three or four patties in a single burger.
Let’s break it down so you know exactly what to expect before ordering one of these monster-sized burgers.
A 3x3, also known as a Triple-Triple, is a burger that comes with:
It’s essentially a Double-Double with an extra patty and cheese, making it perfect for someone who wants more meat without going overboard.
A 3x3 is noticeably bigger than a regular Double-Double, but it’s still manageable to eat with two hands. The extra patty gives it a juicier, meatier taste without making it too overwhelming.
✅ Who Should Order It? If you love a Double-Double but always wish it had just a little more beef and cheese, this is the perfect upgrade.
The 4x4, or Quad-Quad, is the biggest burger you can officially order at In-N-Out. Here’s what’s inside:
This thing is huge. It’s almost impossible to eat like a regular burger because of how tall it is. You might need to smash it down a little or eat it layer by layer.
✅ Who Should Order It? If a Double-Double or a 3x3 doesn’t satisfy your hunger, the 4x4 is the way to go. Just be prepared—it’s a lot of food.
| Feature | 3x3 (Triple-Triple) | 4x4 (Quad-Quad) |
|---|---|---|
| Beef Patties | 3 | 4 |
| Cheese Slices | 3 | 4 |
| Size | Big but manageable | Extremely tall |
| Best For | More meat than a Double-Double | The ultimate In-N-Out experience |
The biggest difference is the extra patty and cheese, but that one extra layer changes everything. The 4x4 is harder to eat, heavier, and definitely more filling.
A Double-Double is the standard go-to for In-N-Out fans. It has:
If you’re thinking about upgrading, here’s how the 3x3 and 4x4 compare:
| Burger | Meat & Cheese | Difficulty to Eat |
|---|---|---|
| Double-Double | 2 patties, 2 cheese | Easy to eat |
| 3x3 | 3 patties, 3 cheese | Bigger, still manageable |
| 4x4 | 4 patties, 4 cheese | Very tall, slightly messy |
One of the best things about In-N-Out is how customizable their burgers are. If you’re ordering a 3x3 or 4x4, here are a few ways to make it even better:
💡 Go for a 3x3 if: You want a bigger, meatier burger but still want to eat it comfortably.
💡 Get a 4x4 if: You’re really hungry and want to go all in. Just know it’s a challenge to eat because of its size.
If you’re feeling extra bold, some locations might let you go beyond a 4x4, but don’t expect it to be easy!
At the end of the day, both the 3x3 and 4x4 are amazing options if you’re looking for something bigger than a Double-Double.
Whichever one you pick, you’re getting a delicious, fresh, and made-to-order burger that keeps In-N-Out fans coming back for more.
