The Standard Filet Mignon Portion
While the answer to "how much does an average filet weigh" isn't a single number, a highly common portion size in the United States is 8 ounces, or approximately 225 grams. This size provides a satisfying and tender meal for one person. It's often cut to a thickness of 1.5 to 2 inches, which is ideal for achieving a perfectly seared crust while maintaining a tender, juicy interior, especially when cooked to medium-rare. This balance of weight and thickness is why the 8-ounce filet has become a benchmark in many steakhouses and for home cooks.
Exploring the Spectrum of Filet Sizes
Beyond the standard 8-ounce cut, filet mignon comes in several other sizes to suit different appetites and preparations.
Petite Filet (5-6 ounces)
For a lighter meal or smaller appetite, a petite filet is often the ideal choice. These cuts typically weigh between 5 and 6 ounces, or about 140 to 170 grams. They are cut from the narrower, tapered end of the beef tenderloin and are sometimes referred to as "tornados". Due to their smaller size, they cook faster, requiring careful monitoring to avoid overcooking.
Steakhouse and Large Cuts (10-12+ ounces)
In many high-end steakhouses, it is common to find larger filets on the menu, weighing 10, 12, or even 16 ounces. These come from the center-cut portion of the tenderloin, known as the Chateaubriand. A larger, thicker cut allows for more precise temperature control for rare to medium doneness, and provides a more substantial, decadent dining experience.
The Whole Beef Tenderloin
All filet mignon steaks are cut from the beef tenderloin, a long, cylindrical muscle located along the cow's spine. A full, untrimmed beef tenderloin typically weighs between 4 and 6 pounds and can yield eight to twelve 8-ounce filets. When purchasing the whole tenderloin, you can trim and portion the steaks yourself, which can be a more economical option. The center-cut produces the most uniform and prized filets, while the ends are often used for smaller tournedos or tenderloin tips.
Factors Influencing Filet Weight and Size
Several factors can affect the final weight of a filet mignon:
- Butcher's Trim: The amount of fat and silver skin trimmed from the whole tenderloin directly impacts the final weight and cost of the filet.
- Country of Origin: Culinary traditions differ. For example, European filet cuts may be smaller and thinner than their American counterparts.
- Serving Context: A restaurant's portion size is a key factor. A casual bistro might serve a 6-ounce filet, while a high-end steakhouse could offer a 10-ounce option.
- Consumer Preference: Butchers can cut steaks to order. Some customers prefer a thinner, faster-cooking filet, while others opt for a thick, rare center.
Comparison of Common Filet Sizes
| Filet Size (oz) | Metric Equivalent (g) | Typical Thickness (inches) | Serving Context | Best For... |
|---|---|---|---|---|
| 5-6 oz (Petit) | 140-170g | 1 - 1.5" | Small appetite, quick cook | Individuals wanting a lighter meal. |
| 8 oz (Standard) | 225g | 1.5 - 2" | Standard restaurant, home cook | Most people seeking a classic filet. |
| 10-12 oz (Large) | 280-340g | 2 - 2.5" | Fine dining steakhouse | Hearty eaters, special occasions. |
How to Choose the Right Filet Size for Your Needs
Selecting the perfect filet size depends on your personal preferences and cooking plan. If you are serving a crowd or want a large, impressive centerpiece for a meal, a whole trimmed beef tenderloin is an excellent, cost-effective choice that can be portioned at home. For a simple weeknight meal or for guests with smaller appetites, the 6-ounce petite filet is a fantastic option. The classic 8-ounce filet strikes a perfect balance, offering a generous and satisfying portion suitable for most diners and cooking methods.
Cooking Tips for Different Sizes
- Thicker Cuts (10oz+): The reverse-sear method is highly recommended for thicker steaks to ensure even cooking and a perfect internal temperature before a final high-heat sear.
- Standard Cuts (8oz): Pan-searing or grilling is the most common method. The thicker cut insulates the center, giving you good control over doneness.
- Smaller Cuts (6oz): Cook quickly over high heat, as their thinner size means they can easily overcook. A fast sear is all that's needed.

Conclusion
Ultimately, while the standard answer to "how much does an average filet weigh" is 8 ounces, the final weight is a nuanced issue influenced by butchering practices, regional differences, and specific dining contexts. From petite 6-ounce cuts for lighter fare to substantial 12-ounce steakhouse portions, there is a filet size to suit every taste and occasion. Understanding these variations empowers you to select and prepare the perfect steak, whether at home or in a restaurant.
