Typical Weight of Tuna Steaks

The most common size for tuna steaks sold at grocery stores or fish markets is around 6 ounces This provides a nice individual portion Each 6 ounce tuna steak is about the size of an average smartphone,

Some other typical tuna steak weights include:

• 4 oz tuna steaks – Good for a single appetizer portion
• 8 oz tuna steaks – Makes a more generous single serving
• 10-12 oz tuna steaks – Large shareable portions

So while tuna steak weights can range from 4-12 ounces or more, the 6 ounce size is the most standard for individual servings.

Key Factors That Affect Weight

Several factors impact the weight of tuna steaks:

Type of Tuna

The most common tuna used for steaks are

• Yellowfin tuna – Also called ahi tuna, it has a bright red color and slightly richer flavor.
• Bluefin tuna – Prized for sushi, it has a deep red color and buttery texture. However, it is not sustainable.
• Albacore tuna – Has a lighter color and milder taste. Better for canned tuna.

For steaks, yellowfin and bluefin tuna provide the best texture and flavor. Since they grow larger than albacore, they also yield thicker, heavier steaks.

Cut of the Steak

Tuna steaks are cut in different ways, which affects the shape and weight:

• Center-cut steaks – Rectangular shape cut from the thickest part of the tuna loin. Heavier weight.
• Tail-end steaks – Triangular shape from the tail section. More tapered and lighter in weight.
• Belly steaks – Cut from the belly. Thinner and more oval shape. Tend to be lighter.

Center-cut steaks will be the heaviest, while belly and tail cuts weigh less.

Portion Size

Of course, the intended portion size also determines the weight of the steak. Individual 6 oz steaks are common. But tuna steaks for sharing may be cut thicker and weigh 10 ounces or more. Portion needs dictate desired weight.

Thickness

A thinner cut tuna steak will weigh less than a thick-cut version at the same length. Steaks trimmed to an even 1-inch thickness will yield consistent portion weights. If the steak tapers or has a thinner belly area, the overall weight will be less.

Average Weight by Species

The species of tuna impacts potential steak weights. Here are some averages:

• Yellowfin tuna – 6-10 oz is common. But large sushi-grade steaks can reach 16 oz or more.
• Bluefin tuna – Prized for sushi, these large tuna yield very thick, heavy steaks from 10 up to 24 oz.
• Albacore tuna – Smaller size limits steaks to about 4-8 oz.
• Skipjack tuna – Smaller flaky texture produces smaller steaks of around 4 oz.

While tuna steak thickness can vary, for individual portions look for tuna steaks in the 6-8 oz range. Larger steaks in the 10-16 oz range make nice shareable portions.
