How to Decode Shrimp Sizes: What Does 16/20 or 21/25 Really Mean?

Ever looked at shrimp packaging and seen numbers like "16/20" or "21/25" but weren’t sure what they meant? These numbers are actually a simple way of describing shrimp sizes based on how many pieces are in one kilogram. Once you understand the system, choosing the right shrimp for your recipe becomes easy. Let’s break it down!

What Do Shrimp Size Numbers Mean?

The numbers on a shrimp pack (like 16/20 or 21/25) indicate the approximate number of shrimp per kilogram. For example, 16/20 means there are between 16 and 20 shrimp in one kilo, while 21/25 means there are between 21 and 25 shrimp per kilo. The smaller the number, the larger the shrimp. So, shrimp labeled 16/20 are much bigger than shrimp labeled 51/60, because you only need 16–20 big ones to make a kilo, versus 51–60 small ones.

Sometimes you may also see a "U" before the number, like U/15. This means “under 15 per kilo” — in other words, fewer than 15 shrimp in one kilo, which makes them extra large. While this size isn’t common in Egypt, it’s helpful to know the system when shopping abroad.

Shrimp Size Categories and Names

Besides the numbers, shrimp are often described with names like “Large,” “Jumbo,” or “Super Jumbo.” These names can vary, but the count per kilo is the most accurate measure. Here’s a quick guide:

• Extra Small – 60+ shrimp per kilo (e.g. 61/70). Perfect for salads, fried rice, or toppings. Browse our shrimp collection for smaller size options.
• Small/Medium – Around 41/50 shrimp per kilo. Great for soups, curries, and pasta dishes. Try adding them with Asian sauces for stir-fries.
• Large – Around 31/40 shrimp per kilo. Ideal for grilling, stir-fries, or kebabs. Works well with cooking essentials like olive oil or garlic butter.
• Extra Large (26/30 count) – 26–30 shrimp per kilo. Meaty and versatile for pastas, tacos, or pan-frying.
• Jumbo (21/25 count) – 21–25 shrimp per kilo. Perfect for shrimp cocktail, baking, or impressive starters. Try our Jumbo Peeled Shrimp (21/25).
• Super Jumbo (16/20 count) – 16–20 shrimp per kilo. Big, juicy shrimp that are excellent for grilling or main dishes. Check our Super Jumbo 16/20 Shrimp.

Why Does Shrimp Size Matter?

The size of shrimp you choose affects both cooking and presentation. Here’s how to decide:

• For grilling or roasting: Choose Jumbo or Super Jumbo. Larger shrimp are easier to grill and look impressive on skewers. Serve with ready-to-cook seafood for a full platter.
• For pasta, curries, or sautéing: Extra Large (26/30) or Large (31/40) give the best balance of flavor and quick cooking.
• For soups, fried rice, or salads: Medium or Small shrimp (41/50 or smaller) work best, as they mix easily with other ingredients and cook in seconds. Pair them with Asian condiments for quick meals.

Portion sizes also matter. If shrimp is the main dish, bigger shrimp mean fewer pieces per person but more satisfaction. For example, 5–6 Super Jumbo shrimp can make a full portion. For mixed dishes, smaller shrimp spread out better and are more economical.
