Determining the weight of 20 shrimp requires knowing their size, as a standardized measure doesn't exist for 'a shrimp'. Shrimp are typically sold by 'count per pound,' which indicates how many individual shrimp make up a single pound (454 grams). The smaller the count number, the larger the shrimp. A package labeled '16/20,' for instance, contains 16 to 20 shrimp per pound. Therefore, 20 shrimp from this pack would weigh roughly one pound or 454 grams. In contrast, 20 shrimp from a bag labeled '41/50' would represent a much smaller total weight.
The Grams in 20 Shrimp by Size
To calculate the approximate weight of 20 shrimp, you can use the average gram weight for each size category. It's important to remember that these are average figures and can fluctuate between producers and depending on whether the shrimp are raw or cooked.
- Extra Small (61-70 count per lb): Each shrimp weighs approximately 6.5-7.4g. 20 shrimp ≈ 130-148 grams.
- Small (51-60 count per lb): Each shrimp weighs approximately 7.4-8.7g. 20 shrimp ≈ 148-174 grams.
- Medium (41-50 count per lb): Each shrimp weighs approximately 10-11g. 20 shrimp ≈ 200-220 grams.
- Large (31-35 count per lb): Each shrimp weighs approximately 13-14.7g. 20 shrimp ≈ 260-294 grams.
- Extra Jumbo (16-20 count per lb): Each shrimp weighs approximately 22.7-28.3g. 20 shrimp ≈ 454-566 grams.
- Colossal (U/15 count per lb): Each shrimp weighs over 30g. 20 shrimp ≈ over 600 grams.
Nutritional Benefits of Shrimp
Shrimp can be an excellent addition to a balanced nutrition diet due to its impressive nutritional profile. It is a very lean source of high-quality protein and is low in both fat and carbohydrates. A typical 3-ounce (85g) serving contains over 20 grams of protein and less than 100 calories. Beyond the basic macros, shrimp is packed with several important vitamins and minerals.
- High in Selenium: A powerful antioxidant that supports immune function and thyroid health.
- Excellent Source of Vitamin B12: Essential for nerve function and the production of red blood cells.
- Rich in Choline: A key nutrient for brain health that impacts cognitive function.
- Source of Antioxidants: The astaxanthin in shrimp, which gives it its pink color, has been shown to reduce inflammation and protect against oxidative damage.
- Heart-Healthy Fats: Contains beneficial omega-3 fatty acids, which help lower blood pressure and reduce the risk of heart disease.
It's worth noting that while shrimp is high in cholesterol, modern research suggests that dietary cholesterol has a minimal impact on blood cholesterol levels for most people. Saturated and trans fats have a much greater effect, and shrimp is low in both.
Integrating Shrimp into a Healthy Diet
To maximize the health benefits and avoid unhealthy preparations, follow these simple guidelines:
- Choose Healthy Cooking Methods: Instead of deep-frying, opt for baking, grilling, poaching, or steaming. These methods preserve the lean nature of the protein without adding excessive fat and calories.
- Season Simply: Enhance the natural flavor of shrimp with fresh herbs (such as dill, parsley, or cilantro), spices, garlic, or a squeeze of fresh lemon or lime juice.
- Incorporate into Favorite Meals: Shrimp's versatility makes it easy to add to a variety of dishes you already enjoy. Add it to pasta, salads, stir-fries, or tacos as a quick and healthy protein swap.
- Use Frozen for Convenience: High-quality frozen shrimp can be more budget-friendly and just as nutritious as fresh, as it is often flash-frozen shortly after being caught.
Potential Risks and How to Choose Wisely
While nutritious, shrimp consumption does carry some risks that consumers should be aware of, primarily related to sourcing and allergies.
- Contaminants: The intensive farming practices in some regions, particularly in Asia and Latin America, have been associated with environmental pollution and the use of antibiotics. Antibiotics can cause allergic reactions in sensitive individuals, and some are banned in the United States.
- Allergies: Shellfish allergies are common and can trigger severe reactions in some individuals. Symptoms can range from mild (hives) to life-threatening anaphylaxis.
- Source Your Shrimp Carefully: The best way to mitigate these risks is by purchasing shrimp from reputable sources. Wild-caught shrimp from the U.S. and Canada tend to have fewer issues with contaminants. For farmed shrimp, look for certification from organizations like the Marine Stewardship Council to ensure sustainable and safe practices. Checking the Country of Origin Labeling (COOL) is also recommended.
Nutritional Comparison: 20 Medium Shrimp vs. Other Proteins
This table compares the nutritional content of 20 medium shrimp (approx. 120g raw weight, or about 100g cooked) to a standard 100g cooked serving of other popular protein sources. The nutritional values are approximate and can vary.

Conclusion
Ultimately, the weight of 20 shrimp is a variable figure that depends entirely on their size. What is consistent, however, is that shrimp is a nutritionally dense food, offering a high-quality protein source with a low calorie count and a wealth of essential vitamins and minerals. By choosing wisely, such as opting for sustainably sourced or wild-caught varieties, and using healthy cooking methods, you can confidently integrate shrimp into a balanced and delicious diet. For most people, the benefits of including shrimp in moderation far outweigh the potential concerns, making it a flavorful and healthy dietary choice.
