Shrimp & Shellfish Calculator

Work out how much shrimp to buy for a group and roughly how many that is by size.

Usage Tip

Buy shell-on for more flavour, or peeled to save prep time.

Shrimp Needed

Total for the group
THE MATH
count = (total grams ÷ 453.6) × shrimp per pound
Shrimp are sold by count per pound: lower count means bigger shrimp.
Allow about 150 g per person as a main, less as a starter or in a mixed dish.
