Catering Supplies Calculator: How Much Do You Need for 50, 100 and 200 Guests?
Order too little and you are sending a runner to the shops mid-service. Order too much and you have paid for cartons that sit in the store room until the next function. Getting catering quantities right is the difference between a smooth event and an expensive guess - and it comes down to a few simple per-guest numbers.
This calculator turns your headcount into an order list. It gives you per-guest allowances for every disposable catering line - plates, cutlery, cups, napkins, foil trays and more - with worked examples for 50, 100 and 200 guests, then maps each quantity to the wholesale carton pack sizes we stock. If you are still deciding which products to use (eco versus conventional, napkin folds, cutlery grades), read our disposable tableware buying guide for caterers and events first, then come back here to work out how much to order.

- Multiply your headcount by 1.1 to build in a 10% buffer, then always round up to the next full carton.
- A safe buffet baseline per guest: 2 plates, 3 napkins, 1 set of cutlery and 1 to 2 cups.
- A buffet needs roughly 15 to 20% more plates than plated service - guests come back for seconds.
- Count servingware (foil roasters, platters) by the number of dishes, not by guest.
- One wholesale carton stretches a long way - a single carton of most lines covers a whole 50 to 100 guest event.
How to use this catering quantity calculator
The tables below already do the maths for you, but it helps to know the assumptions behind them so you can adjust for your own event. Every quantity is a per-guest allowance multiplied by your headcount, with a 10% buffer added and the result rounded up to a full carton.
Assumptions this calculator uses
- Buffet, not plated. The default allowances assume a buffet or grazing-style service where guests self-serve and often return. Plated service uses about 15 to 20% fewer plates and less cutlery.
- Event length drives cups. Allow 1 cup per guest for an event under 3 hours, and 2 to 3 cups per guest for longer events or anything with a bar. Hot and cold cups are counted separately.
- Time of day drives napkins. A morning tea or cocktail function needs 1 to 2 napkins per guest; a sit-down dinner needs 3 or more.
- The 10% buffer is already included. It covers spills, doubles and the guests who quietly bring a friend.
How to read the tables
- The quantity column is total units including the 10% buffer.
- The cartons to order column rounds up to whole wholesale cartons - you cannot order half a carton, and the leftover is next event's stock.
- Costs quoted later are indicative and shown ex GST, the B2B default. Check the live product page for current carton pricing.
Adjust for your service style
Buffet or plated? It changes your numbers
Service style is the single biggest swing on your order. Guests at a buffet grab a fresh plate on the return trip and often pick up new cutlery, so you plan for more. A plated, seated service is far more predictable - one plate, one setting, one refill.
- Buffet or grazing: 2 plates and 1.5 sets of cutlery per guest.
- Plated, seated: 1.25 plates and 1 set of cutlery per guest.
- Cocktail or canapes: skip large plates - allow 2 to 3 small plates or napkins per guest instead.
- Add a dessert or cheese course: add 1 side plate and 1 bowl per guest.
Worked example
Catering supplies for 50 guests
A typical corporate morning tea, milestone birthday lunch, sports presentation or small reception. At this size a single wholesale carton covers almost every line.
| Item | Quantity needed (incl. 10% buffer) | DPack cartons to order |
|---|---|---|
| Dinner plates | 111 | 1 carton (500) |
| Side / dessert plates | 56 | 1 carton |
| Bowls (salad / dessert) | 56 | 1 carton |
| Cutlery pieces (fork, knife, spoon) | 165 | 1 carton (400) |
| Napkins / serviettes | 165 | 1 carton (2000) |
| Cold cups / tumblers | 111 | 1 carton (1000) |
| Hot cups (tea & coffee) | 56 | 1 carton (1000) |
Servingware is counted separately: for a 50-guest hot buffet allow 3 to 4 foil roasting trays (1 per hot dish) and 4 catering platters for cold spreads.
The benchmark event
Catering supplies for 100 guests
The most common catering benchmark, and the point where per-carton pricing really pays off. This is the full working table - per-guest allowance, total quantity, the closest DPack carton and how many to order.
| Item | Per guest | Quantity (incl. 10%) | Closest DPack carton | Cartons to order |
|---|---|---|---|---|
| Dinner plates | 2 | 221 | 9" sugarcane round, 500 / carton | 1 |
| Side / dessert plates | 1 | 111 | 7" sugarcane round, 1000 / carton | 1 |
| Bowls (salad / dessert) | 1 | 111 | Paper bowl, 500 / carton | 1 |
| Cutlery pieces | 3 | 330 | Wooden cutlery combo, 400 / carton | 1 |
| Napkins / serviettes | 3 | 330 | 2-ply lunch napkins, 2000 / carton | 1 |
| Cold cups / tumblers | 2 | 221 | 425ml plastic cups, 1000 / carton | 1 |
| Hot cups (tea & coffee) | 1 | 111 | 12oz single-wall cups, 1000 / carton | 1 |
Notice how far a single wholesale carton stretches at 100 guests - that is the core cost advantage of buying catering supplies by the carton rather than in retail multipacks. Add 4 to 6 foil roasting trays for a hot buffet (1 per dish) and 7 to 8 platters for cold food.

Catering supplies for 200 guests
Full wholesale territory - large weddings, galas, conferences and community events. This is where ordering cartons of cartons, direct from a wholesale supplier, makes a real difference to your per-head cost versus retail.
| Item | Quantity needed (incl. 10% buffer) | DPack cartons to order |
|---|---|---|
| Dinner plates | 441 | 1 carton (500) |
| Side / dessert plates | 221 | 1 carton |
| Bowls (salad / dessert) | 221 | 1 carton |
| Cutlery pieces (fork, knife, spoon) | 660 | 2 cartons (400) |
| Napkins / serviettes | 660 | 1 carton (2000) |
| Cold cups / tumblers | 441 | 1 carton (1000) |
| Hot cups (tea & coffee) | 221 | 1 carton (1000) |
For a 200-guest hot buffet allow 8 to 12 foil roasting trays and 14 to 16 platters. This is the scale where a standing order with a wholesale catering supplies account saves the most.
Per-item planning guide: what to know before you order
The tables give you the numbers. This section covers the judgement calls behind them, item by item. For deeper product selection - materials, grades and eco options - route back to our disposable tableware buying guide for caterers and events.
Plates and bowls
Round plates suit plated meals; larger oval or rectangular plates carry buffet portions better. For events over 150 guests, 500-plate cartons keep your per-unit cost down and cut the number of packs to open on the day. Shop disposable plates and tableware wholesale.
Cutlery
Individually wrapped cutlery sets are the hygiene standard for events and cut handling; loose cutlery is cheaper for back-of-house or self-serve stations. Count by role - a dessert course means a spoon per guest on top of the main setting. Compare disposable cutlery wholesale.
Cups and drinkware
Hot and cold are different products - do not let one number cover both. Allow 2 cups per guest once there is a bar or the event runs past 3 hours, and add dessert tumblers as their own line if you are serving individual desserts. Order cold cups and tumblers wholesale, or browse drinkware and tumblers wholesale for reusable options.
Napkins and serviettes
Use 2-ply at dinner and 1-ply for cocktail service or morning tea. Plan 3 napkins per guest at a sit-down dinner as a minimum - they get used for more than wiping hands. Stock up on bulk paper napkins wholesale.
Count by dish, not by guest
Servingware: foil roasters, grazing boxes and tablecloths
Servingware does not scale per guest - it scales with the menu and the table plan. Work these out from your run sheet, not your headcount.
- Foil roasters: roughly 1 large tray per hot dish. A three-dish buffet for 100 guests needs 4 to 6 trays, not one per table. Browse foil containers and roasters wholesale.
- Catering trays and platters: about 1 per 12 to 15 guests for cold spreads and grazing. See catering trays and platters wholesale.
- Grazing boxes: window-lid boxes in three sizes - allow 1 box per 2 to 3 guests for a shared grazing station, or 1 per guest for individual serves.
- Tablecloths: 1 per table seating 8 to 10, plus a couple of spares for the buffet and gift tables.

Common questions
Catering quantity planning FAQs
How many plates per person for a buffet?
Allow 2 plates per guest for a buffet, because guests take a fresh plate on the return trip. With a 10% buffer that is about 220 plates for 100 guests. Plated, seated service needs fewer - roughly 1.25 plates per guest.
How many napkins per person for a catering event?
Plan 3 napkins per guest for a sit-down dinner, 2 for a lunch, and 1 to 2 for a morning tea or cocktail function. A single 2000-napkin carton comfortably covers most events up to 200 guests.
How many cups per person for an event?
Allow 1 cup per guest for an event under 3 hours, and 2 to 3 for longer events or anything with a bar. Count hot cups (tea and coffee) and cold cups separately - they are different products and guests use both.
How do I calculate how many foil trays I need for a buffet?
Count foil roasting trays by dish, not by guest - roughly 1 large tray per hot dish. A three to four dish buffet for 100 guests needs 4 to 6 trays. Add a couple of spares for the kitchen.
What is the standard catering quantity rule of thumb?
Multiply your headcount by 1.1 to add a 10% buffer, then round up to the next full wholesale carton. Never round down - running short mid-service costs far more than a part-used carton.
How many grazing boxes do I need per person?
Allow 1 grazing box per guest if you are serving individual boxes, or 1 box per 2 to 3 guests if the grazing is a shared supplementary station alongside a main menu.
