In-N-Out 3x3 Burger 2026: Price, Calories & How to Order
In-N-Out 3x3 Burger, also called the Triple Triple, is a Not-So-Secret Menu burger made with three beef patties and three slices of American cheese. It keeps the familiar In-N-Out bun, lettuce, tomato and spread, with onions available by choice. This 2026 guide covers the 3x3 price, ingredients, calorie guidance, Animal Style and Protein Style options, and exactly how to order it.
In-N-Out 3x3 Burger Price 2026

What Is the In-N-Out 3x3 Burger?
The 3x3 is an established item on In-N-Out's official Not-So-Secret Menu. In-N-Out also calls it the 3x3 or Triple Triple. Its defining feature is simple: three 100% American beef patties paired with three slices of American cheese.
The official build also includes hand-leafed lettuce, tomato and spread on a freshly baked bun, with or without onions. That makes it essentially a larger progression from the Double-Double rather than an unrelated secret-menu creation.
What Comes on an In-N-Out 3x3?
Three Beef Patties
The Triple Triple uses three beef patties. In-N-Out says its hamburger patties are made from fresh 100% USDA ground chuck without additives, fillers or preservatives.
Three Cheese Slices
Each patty level is paired with American cheese, giving the 3x3 three slices in total.
Lettuce, Tomato & Spread
The standard 3x3 keeps the familiar lettuce, tomato and In-N-Out spread found on the chain's core burgers.
Onions Your Way
The official description allows the burger with or without onions. Additional preparation requests can be made when ordering.
In-N-Out 3x3 Calories and Nutrition
There is an important distinction between an estimate and an official nutrition figure. In-N-Out's current nutrition information provides figures for standard items such as the Hamburger, Cheeseburger and Double-Double, but it does not list a dedicated official nutrition panel for the 3x3.
For comparison, In-N-Out currently lists a standard Double-Double with onion at 610 calories, with 34 grams of fat and 34 grams of protein. Because the 3x3 adds another beef patty and another slice of cheese, its total will be higher. However, we do not label a calculated estimate as an official In-N-Out calorie figure.
How to Order an In-N-Out 3x3 Burger
Ordering is straightforward. Ask the associate for a “3x3” or a “Triple Triple.” Both names refer to the three-patty, three-cheese burger described by In-N-Out.
You can then specify your preferred onions and other available customizations. If you want Animal Style or Protein Style, say so as part of the same order—for example, “3x3 Animal Style” or “3x3 Protein Style.”
3x3 vs Double-Double
| Feature | Double-Double | 3x3 / Triple Triple |
|---|---|---|
| Beef Patties | 2 | 3 |
| Cheese Slices | 2 | 3 |
| Bun | Yes | Yes |
| Lettuce & Tomato | Yes | Yes |
| Spread | Yes | Yes |
| Official standard calories | 610 with onion | No dedicated figure published |
The practical difference is the additional patty and cheese slice. Someone who likes the Double-Double format but wants a larger beef-and-cheese portion can move to the 3x3 without changing the basic burger structure.
3x3 vs 4x4: What's the Difference?
The next step above the Triple Triple is the 4x4, also known as the Four by Four or Quad Quad. In-N-Out officially describes the 4x4 as four beef patties and four American cheese slices with lettuce, tomato, spread and optional onions on a bun.
| Burger | Patties | Cheese | Our 2026 Price Reference |
|---|---|---|---|
| Double-Double | 2 | 2 slices | See local menu |
| 3x3 / Triple Triple | 3 | 3 slices | About $8.50 |
| 4x4 / Quad Quad | 4 | 4 slices | About $10.99 |
Can You Order a 3x3 Animal Style?
Yes. Animal Style changes the preparation rather than the number of patties. In-N-Out describes Animal Style as a burger with a mustard-cooked beef patty plus pickle, extra spread and grilled onions, along with lettuce and tomato.
A 3x3 Animal Style therefore combines the three-patty, three-cheese Triple Triple format with the Animal Style preparation. For the complete breakdown, see our In-N-Out Animal Style Menu 2026 guide.
Can You Order a 3x3 Protein Style?
Protein Style replaces the bun with hand-leafed lettuce. Because the 3x3 is a burger customization platform, you can request the Triple Triple Protein Style if you prefer a lettuce wrap rather than the standard bun.
Protein Style should not be confused with Animal Style. Protein Style changes the bun, while Animal Style changes preparation and toppings. Customers can also ask about combining the two customizations.
Is the 3x3 Really a Secret Menu Item?
“Secret menu” is the popular phrase, but In-N-Out itself calls these options its Not-So-Secret Menu. The company openly lists the 3x3 alongside the 4x4, Grilled Cheese, Protein Style and Animal Style.
