Potatoes for mashed potatoes and sides

Mashed potato portions often run 170–230 g (about 6–8 oz) of raw potato per person when potatoes are a featured side — less if the table includes several starches. This calculator multiplies your per-guest gram target by headcount and converts to total pounds and an approximate potato count.

Average russet potatoes weigh about ½ lb (225 g) each, but sizes vary widely at the store. Weighing at checkout or buying by the bag is more reliable than counting eyes — the potato count here rounds up from total weight assuming medium russets.

Example: 10 guests at 200 g per person for classic mashed potatoes needs 2,000 g total — about 4.4 lb or roughly 9 medium russet potatoes before peeling and trimming.

Common questions

How many grams of potato per person for mashed potatoes?

About 170–230 g (6–8 oz) of raw potato per guest is typical when mashed potatoes are a main side. Use 150 g or less if several other starches are on the menu.

Does this include butter, milk, or cream?

No — only raw potato weight. Add butter, milk, cream, and seasonings separately using your recipe or the recipe scaler.

How accurate is the potato count?

It assumes medium russets at about ½ lb each and rounds up. Actual counts depend on potato size — use total weight as your shopping guide.
