How Much Soup Per Person? UK Portion Guide

How Much Soup Per Person?

Quick Answer

200ml for a starter, 350ml for a main course, 250ml for a mug serving

Main course volume assumes soup served with bread. Standing it alone as a meal, allow nearer 360-480ml. Add 15-20% extra if people are likely to want seconds.

Soup Portion Sizes at a Glance

Serving type	Per person	Note
Starter	200ml	first-course range 120-240ml, about one cup
Main course (with bread)	350ml	standalone main is nearer 360-480ml
Mug serving	250ml	a comfortable fill for a standard 300ml mug

These are typical UK catering heuristics, not a regulated standard. For heartier soups (with beans, meat, or pulses) the smaller end of a range works; for thin or brothy soups go towards the larger end. The full soup portions calculator scales these figures to your exact guest count and adds bread and cream quantities.

Worked Example: Dinner Party for 8

For a main course served with bread, the calculator uses 350ml per person:

Soup needed: 8 × 350ml = 2,800ml (2.8 litres)
Bread rolls (1 per person): 8 × 1 = 8 rolls
Cream for garnish (15ml per person): 8 × 15ml = 120ml

Worked Example: Buffet Starter for 20

For a starter portion the figure drops to 200ml per person:

Soup needed: 20 × 200ml = 4,000ml (4 litres)
A standard ladle holds about 120ml, so that is roughly 4,000 ÷ 120 ≈ 33 ladles in total, or about 1.7 ladles per starter bowl

Worked Example: Adding a Buffer for Seconds

For a casual family meal for 6, main course, where people often want a top-up, add 15-20% extra. At 20% extra:

Base volume: 6 × 350ml = 2,100ml
With 20% extra: 2,100ml × 1.2 = 2,520ml (about 2.5 litres)

For formal dinners and events with other courses to follow, the standard portion is usually enough on its own.

Bread and Accompaniments

Allow 1-2 bread rolls per person, or 2-3 slices of crusty bread. For a bread basket at a dinner party, allow about 80g of bread per person. If you are adding a cream garnish, 15ml per person is a typical amount.

Why the Range Varies

Soup portions vary more than most catering figures because soup does double duty: it can be a light first course or the whole meal. A starter before two more courses only needs 120-240ml, while soup standing in as a main meal (especially a hearty, chunky one) wants 360-480ml to be filling on its own. The soup portions calculator builds in the bread-roll assumption for its main-course figure, so if you are serving soup with no bread at all, move towards the top of the main-course range.
