T-Bone and Porterhouse steaks are both popular cuts of beef that come from the short loin section of a cow, characterized by their distinctive T-shaped bone. While they share similarities, the primary difference lies in the size and location of the filet portion, which is the tenderloin part of the steak. Porterhouse steaks are generally larger than T-Bone steaks and contain a more substantial portion of tenderloin. According to the U.S. Department of Agriculture (USDA), a Porterhouse must have a tenderloin section that is at least 1.25 inches wide at its thickest point, whereas a T-Bone needs a tenderloin portion that is only at least 0.5 inches wide. This makes the Porterhouse ideal for those who prefer a larger amount of the more tender filet meat. Both cuts feature the strip steak on the other side of the bone, offering a combination of textures and flavors in one cut. Due to the larger size and more generous portion of tenderloin, Porterhouse steaks are often considered more luxurious and typically come with a higher price tag. In cooking, both cuts benefit from similar methods, such as grilling or broiling, to enhance their natural flavors.

When it comes to the T-bone vs. porterhouse, size matters

While porterhouse and T-bone steaks come from the same section of the cow, they look different on the butcher's block. A butcher will point out the defining feature of the T-bone: the T-shaped bone that divides the filet mignon on one side from the New York strip steak on the other. When these two cuts are left intact, you have a T-bone steak. This impressive cut makes its name seem rather modest.

The porterhouse, cut from the end of the short loin, also features a T-shaped bone. To add to the confusion, it includes the same cuts of meat as the T-bone: the filet and the strip. However, the porterhouse is typically larger and often marketed as a dish "for two" in restaurants.

The distinction between a T-bone and a porterhouse ultimately comes down to government regulations. According to the USDA, for a steak to be classified as a porterhouse, "the maximum width of the tenderloin must be at least 1.25 inches (3.2 cm) when measured parallel to the length of the backbone." In contrast, the T-bone's maximum width is only half an inch. So, the next time you find yourself enjoying a steak at a chophouse in the U.S., feel free to whip out a ruler to ensure that your porterhouse isn’t just a clever disguise for three T-bones stacked together.
