Fondue Pot Size Calculator
Get the liquid volume your table needs and the smallest pot that holds it safely.
Your pot size
Why headspace matters
A fondue pot that looks perfectly sized when it is cold behaves very differently once the burner is lit. Cheese froths as it emulsifies, chocolate can bubble around the edges, and broth for a hot-pot-style fondue rises noticeably as it comes to temperature. (Hot oil is not sized by this calculator: an oil pot is filled only to its maker’s stated level.) A pot filled to the rim leaves nowhere for that rise to go.
Working backward from your guest count to a recommended capacity — rather than eyeballing it — is the simplest way to avoid a scorched burner, a ruined tablecloth, or a spattered hand.
Frequently Asked Questions
How full should you fill a fondue pot?
For cheese, chocolate, and broth, no more than about two-thirds of its rated capacity. They all bubble and rise as they heat, and a pot filled to the brim has nowhere for that expansion to go — the result is spattering, mess, and a real burn risk. This calculator uses a 66% maximum fill by default. Hot oil is different: fill an oil pot only to the level its maker gives, which is lower, because hot oil spatters and can catch fire. Keep a lid within reach and never use water on an oil fire.
How much fondue liquid does one person need?
About 200ml of melted cheese, chocolate, or broth per guest is a reasonable planning figure for a main course; less for a dessert fondue or a starter course. Multiply that by your guest count to get the total volume the pot needs to hold.
What size pot do I need for a dinner party of 8?
At 200ml per guest, 8 guests need 1,600ml of liquid. Kept to a 66% maximum fill, that calls for a pot rated at roughly 2,500ml (2.5 litres) or larger — this calculator does the rounding for you to the nearest common pot size.
