Two numbers cover almost every situation: about 2 oz (55–60 g) per person when a meal follows, and about 5 oz (150 g) when the cheese board is the meal. Everything else is adjustment.
Why published figures disagree so much
Search this and you will find appetizer guidance ranging from 1 oz to 3.5 oz, and main-event guidance from 3 oz all the way to 8 oz. That is not sloppiness — the sources are answering different questions. A cheesemonger sizing an after-dinner course assumes people have eaten. A grazing-table caterer assumes they have not. And several sources quote their figure per cheese rather than in total, which quietly triples the number if you misread it.
The figures below sit in the middle of the well-sourced range, with a small buffer. Cheese keeps, and running out is the worse failure.
How much to buy
| Occasion | Per person | For 10 guests |
|---|---|---|
| Appetizer, meal to follow | 2 oz / 57 g | 570 g |
| Cocktail party, no dinner | 3 oz / 85 g | 850 g |
| Cheese & wine tasting | 4 oz / 115 g | 1.15 kg |
| Board as the main event | 5 oz / 150 g | 1.5 kg |
| After-dinner cheese course | 1.5 oz / 45 g | 450 g |
Grazing for more than two hours? Add about 25%. People eat steadily rather than in one pass, and a board that sits out gets picked at all evening.
How many different cheeses
Three to five. Five is the ceiling, and every serious source agrees on that.
This is where scaling up goes wrong. For thirty guests you do not buy fifteen cheeses — you buy more of the same four. Past five varieties the individual flavours stop registering; guests cannot hold that many impressions at once, and the board reads as a pile rather than a selection.
| Guests | Cheeses | Of each (appetizer) |
|---|---|---|
| Up to 6 | 3 | ~110 g |
| 8–15 | 4 | ~140–210 g |
| 16+ | 5 | ~180 g and up |
The selection rule worth memorising
Something old, something new, something goat, something blue.
- Old — a firm aged cheese. Cheddar, aged Gouda, Gruyère, Manchego.
- New — soft and ripened. Brie, Camembert, a triple crème.
- Goat — fresh chèvre, or an aged goat's cheese for more character.
- Blue — Gorgonzola, Stilton, Roquefort.
If blue is genuinely unpopular in your crowd, replace it with something washed-rind or smoked. Do not replace it with a fifth mild cheese — you lose the contrast that makes a board interesting.
Everything else on the board
| Item | Appetizer | As the meal |
|---|---|---|
| Cured meat | 2 oz / 57 g | 3.5 oz / 100 g |
| Crackers & bread | 6–8 pieces | 10–12 pieces |
| Fruit & vegetables | 2 oz / 57 g | 4 oz / 113 g |
| Nuts & dried fruit | 1 oz / 28 g | 2 oz / 57 g |
| Jam, honey & dips | 1 oz / 28 g | 2 oz / 57 g |
Two or three cured meats is plenty — something sliced thin like prosciutto, something firm like salami, and optionally something spreadable or spicy.
Board size
- 2–4 people — 8–12 inches
- 6–10 people — 12–18 inches
- 10–20 people — 18–24 inches
- 20+ — stop thinking "board" and build a grazing table. A single board that large is unwieldy and nobody can reach the middle.
Small things that make a real difference
- Out of the fridge an hour before. Cold mutes flavour and makes soft cheese rubbery. This is the highest-impact thing on the list and it costs nothing.
- A separate knife per cheese, or at least one per style. Blue transfers to everything.
- Pre-cut the hard cheeses, leave soft ones whole. People hesitate to cut the first slice from an intact wheel, but they will happily take a pre-cut wedge.
- Label them if you have more than three. Guests eat more when they know what they are picking up.
