It is one of the first questions any organiser asks, and one of the trickiest to answer without knowing the full picture. How much food do you actually need per person? Order too little and guests go hungry; order too much and you have wasted budget and food. Getting the quantities right sits at the heart of good event catering, and the answer depends on more than just guest numbers.
This guide sets out practical figures for the three formats we are asked about most often at Smiths Catering London: canapés, bowl food, and finger buffets. Use it as a starting point when you are planning your event, then speak to us if you would like figures tailored to your specific occasion.
Canapé Quantities: The Numbers You Need
Canapés are the most common area of confusion, largely because the right quantity depends on what role they are playing at your event.
For a drinks reception where canapés are being served alongside other food, or where guests have eaten beforehand, six to eight pieces per person is a reasonable guide. If canapés are the primary food offering for the evening, that figure rises to ten to fourteen pieces per person, depending on the richness of the items and the length of the reception.
As a rule of thumb:
– Pre-dinner drinks reception (45 to 60 minutes): 4 to 6 pieces per person
– Standalone drinks reception (90 minutes to 2 hours): 8 to 10 pieces per person
– Canapés as meal replacement (2 hours or more): 12 to 14 pieces per person
For corporate events and evening receptions in London, we typically recommend a minimum of three to four different varieties so guests with different tastes and dietary requirements are well catered for. Browse our canapé menu to see what is available.
Bowl Food Portions
Bowl food has become increasingly popular for standing receptions where organisers want something more substantial than canapés but do not want the formality of a sit-down meal. The format works particularly well for corporate events, product launches, and end-of-year celebrations.
A standard serving of bowl food is roughly 150 to 200g per dish. For a standalone bowl food reception where this is the main food offering, three to four portions per person is the norm. If bowl food is being served alongside canapés, two portions per person is usually sufficient.
Event length matters here too. A two-hour reception with bowl food and no other food offering will require more per head than a 90-minute event where guests arrive having had lunch.
Take a look at our bowl food menu for a sense of the options available.
Finger Buffet and Hot Buffet Quantities
For finger buffets, the standard guide is eight to ten pieces per person for a lunchtime event, rising to ten to twelve pieces for an evening occasion where the buffet forms the main meal. A good finger buffet should offer a mix of hot and cold items, with vegetarian and dietary options spread throughout the spread rather than treated as an afterthought.
For hot buffets, portion weights are more straightforward. A typical serving is 200 to 250g of protein and a similar quantity of sides and accompaniments per person. For events running over two hours, or where a gap between arrival and eating is expected, it is worth building in a small buffer above the base figure.
Our finger buffet menu covers a wide range of options suited to office lunches, corporate away days, and informal evening events across London.

What Else Affects the Quantities?
A few factors consistently change the calculation. Time of day matters: guests at a lunchtime event tend to eat more than those at an evening reception where they may have had a large meal earlier. Event length is equally important; a three-hour drinks reception needs more food than a 90-minute networking event. Guest demographics can also play a role, though this is harder to plan for precisely.
For corporate catering in London, we always discuss these variables with clients before confirming quantities. Getting this right is part of the service.
