Enter your guest count, choose appetite and occasion, and this sushi calculator for party planning, a servings guide for ordering, returns total pieces, rolls, 40 piece platters, uncooked rice and fish in one step. Use this sushi calculator for a party, a crowd, an office lunch or a family dinner, then adjust for children, vegetarians and guests who do not eat raw fish. Amounts are planning estimates for a mixed platter, not a substitute for professional food safety advice, so keep raw fish cold and follow the food safety guidance below.
The calculator starts with base pieces per person for your occasion, then adjusts that base for appetite. An appetizer serving uses 8 pieces per person, a party snack uses 10, a main meal uses 12, and a sushi focused dinner uses 15. Light appetite multiplies the base by 0.75, average appetite keeps it at 1.0, and hearty appetite multiplies it by 1.25. Total pieces are rounded to a whole piece, rolls are rounded up at 8 pieces per roll, and 40 piece platters are rounded up so you never order a fraction of a platter. Rice is counted at 10 grams uncooked per piece and fish at 12 grams per piece, which gives a practical shopping total for a mixed platter without pretending every piece is identical.
Start with the real guest count, not the invited count, and count children separately in your head if many children are coming, since children usually eat about half an adult portion. Choose the occasion that matches how sushi fits the meal, then choose appetite honestly for the group. Use the platter total when ordering from a caterer, and use the roll total when ordering individual rolls. If the result sits just above a whole platter, keep the extra platter rather than trimming it, because running out is harder to fix than having a few pieces left over.
Light vs hearty appetite is the single biggest reason two hosts order very different amounts for the same guest count. A light group picking at sushi before a larger meal needs far less than a hearty group making sushi the main event. The same logic applies to appetizer vs main meal portions: an appetizer serving of 6 to 8 pieces per person works when other foods follow, while a main meal serving of 10 to 14 pieces per person is the safer range when sushi carries the meal. When in doubt, pick the higher appetite for evening events, longer parties and groups of keen sushi eaters, and pick the lower appetite for lunchtime events with plenty of sides.
A good platter mixes maki rolls, nigiri and sashimi instead of repeating one roll. Maki rolls are filling because of the rice, nigiri gives a cleaner fish taste with a small rice base, and sashimi is pure fish with no rice, so it suits guests who want protein without extra rice. For variety, include a cooked and familiar roll such as California or shrimp tempura, a raw classic such as spicy tuna or salmon, a colourful option such as rainbow, and a vegetarian roll such as cucumber or avocado. Sushi platter sizes vary by shop, but small platters commonly feed 3 to 4 people, medium platters feed 5 to 7, and large platters feed 8 to 10, so always check the piece count on the platter you are actually buying and compare it with the total pieces from this calculator.
Ordering suits large groups, tight schedules and raw fish, because a caterer cuts fresh fish on the day and handles the rice, platter sizes and presentation. Making a homemade sushi platter suits smaller groups and cooked or vegetarian fillings, and it gives full control over rice, fish and accompaniments. A homemade sushi platter for a crowd needs careful timing: cook the rice close to serving time, keep fillings cold until rolling, and roll in small batches so pieces stay fresh. For ordering, ask when the rolls will be cut, what is included besides the rolls, and how the platter will be kept cold during delivery, and order at least a week ahead for larger parties.
Sushi food safety for raw fish starts with cold storage: keep a platter refrigerated or on ice until serving, take it out only 15 to 20 minutes before guests eat, and do not leave raw fish at room temperature for more than 2 hours in total. Buy sushi grade fish only from a trusted supplier, keep raw fish separate from cooked foods and utensils, and discard leftovers that have sat out too long rather than saving them. Serve accompaniments on the side so guests can choose: soy sauce, tamari for gluten free guests, wasabi, pickled ginger, plus simple sides such as edamame, miso soup and seaweed salad. Label vegetarian, cooked and raw sections clearly, and keep shellfish pieces apart for guests with shellfish allergies.
Plan 10 to 12 pieces per person for a typical party where sushi shares the table with appetizers, 14 to 16 pieces per person when sushi is the whole meal, and 6 to 8 pieces per person when sushi is one of several stations. Children usually eat about half an adult portion. This calculator applies those ranges through your occasion and appetite choices.
A standard roll is cut into 8 pieces, so 10 to 12 pieces per person is about 1.5 rolls per person, and 14 to 16 pieces is about 2 rolls per person. For a light lunch, 1 roll per person is often enough. Use the roll total from the calculator rather than guessing, and round up so every guest can take a second helping of a favourite roll.
For 10 people as a main meal at average appetite, this calculator gives 120 pieces, which is 15 rolls and 3 platters of 40 pieces. For 10 people as an appetizer at light appetite, it gives 60 pieces, which is 8 rolls and 2 platters. Change the occasion and appetite inputs to match your actual event before ordering.
Most standard maki rolls are cut into 6 to 8 pieces, with 8 pieces the most common restaurant cut. Specialty rolls can be cut into 8 to 10 pieces, and a hand roll is a single large cone rather than sliced pieces. This calculator uses 8 pieces per roll, so if your shop cuts 6 pieces per roll, divide the total pieces by 6 instead of 8 for the roll count.
For a mixed platter, allow about 10 grams of uncooked sushi rice per piece and about 12 grams of fish per piece. That means 120 pieces need 1200 grams of uncooked rice and 1440 grams of fish. For sushi rice per person, a main meal serving of 12 pieces needs about 120 grams of uncooked rice per person. For how much fish for sushi per person, the same serving needs about 144 grams of fish per person. These are blended planning rates for a mixed platter, not exact rates for a single roll type.
Mix cooked and raw, mild and spicy, familiar and signature rolls. A reliable mix is California, spicy tuna, shrimp tempura, dragon and rainbow, plus a vegetarian roll and a small sashimi sampler of salmon, tuna and yellowtail for guests who prefer pure fish. Include at least 5 different rolls for a party platter so guests with different tastes all find something they enjoy.
Order at least one week ahead, and two weeks ahead for 40 or more guests or premium platters. Keep the platter refrigerated or on ice until serving, unwrap it only when guests are ready, and do not leave raw fish out for more than 2 hours in total. Ask the caterer when the rolls will be cut, since same day cutting tastes noticeably fresher than rolls made the night before.
Yes, with a little planning. Offer cucumber, avocado and sweet potato rolls for vegetarian guests, keep cooked rolls for guests who do not eat raw fish, and serve tamari on the side for gluten free guests, since standard soy sauce contains wheat and tempura batter and imitation crab can also contain wheat. Label the vegetarian, cooked and raw sections, keep shellfish separate, and ask guests about allergies before you order.
