Order a moderate number of drinks per person for every hour your meeting runs, then round up to full packaging units. Push that number higher for half-day sessions, hot-drink-heavy breakfasts, or summer afternoons when water disappears fast. Everything else, the exact mix, the buffer, and the packaging math, comes down to the numbers below.

TL;DR:

  • Ordering for half-day meetings requires roughly 180 servings, with an extra safety buffer to accommodate unexpected demand.
  • Water should constitute about 50% of the order for short meetings and 40% for all-day events, to serve as the primary fallback.
  • Hot drinks are consumed most heavily in morning sessions, making up nearly half of the beverages during breakfast meetings.
  • Always round up quantities to full packages and add a 10% buffer for larger or back-to-back events to avoid shortages.
  • Placing water at the room entrance and using staffed hot drink stations for large groups improves logistics and reduces delays.

How Do You Calculate Drinks Per Person for a Meeting?

The formula is simple: total servings equal the product of attendees, hours, and an estimated drinks-per-person-per-hour rate. This rate is a moderate average used by caterers, typically between the low and high bounds often quoted. It works for a typical indoor meeting where people are seated, talking, and not doing anything physically demanding.

A “serving” varies by drink type. Hot drinks typically count as a cup of about 200 to 250 milliliters, while cold drinks often come in containers ranging from 250 to 400 milliliters. When you’re converting totals into liters for a shopping list, that distinction matters, because a case of 330 ml cans covers fewer “servings” than the same volume in a 1.—liter jug.

Here’s how that plays out in practice:

  1. Short meeting: 12 people for 1 hour. That’s 12 × 1 × 1.— = 18 servings. Split roughly across water, coffee or tea, and one soft drink option, you’re looking at around 9 bottles of water, 6 hot drinks, and 3 soft drinks, rounded to whatever pack sizes your supplier offers.
  2. Half-day meeting: 30 people for 4 hours. That’s 30 × 4 × 1.— = 180 servings. Add a small safety buffer to the total orders to cover unexpected demand, which might mean multiple water cases, refills for hot drinks, and variety in soft drinks.

Once you have the total, the next question is how to split it between water, coffee, and everything else.

How Should You Split Water, Hot Drinks, and Soft Drinks?

Water carries the biggest share of your order because it’s the fallback drink for everyone, including people who skip coffee, avoid sugar, or simply forget to grab something. PartyCalcs’ non-alcoholic drinks guidance recommends building totals around water first and layering juice, fizzy drinks, and squash on top, rather than treating all beverage types as interchangeable.

A workable split for most office meetings:

  • Short internal meetings (under 2 hours): roughly 50% water, 35% hot drinks, 15% soft drinks.
  • All-day workshops: closer to 40% water, 30% hot drinks, 30% soft drinks, since variety matters more over a longer stretch.
  • Breakfast meetings: flip the hot-drink share up to 45 to 50%, since coffee and tea dominate the first two hours of any morning event.

For hot drinks, plan on a higher consumption in the morning and less in the afternoon, reflecting typical guest preferences. A shared pitcher works fine for water, but individual bottles reduce contact and cut down on wasted half-full cups at the end of a session.

Pro Tip: Keep the drink menu short. A curated lineup, coffee, tea, still and sparkling water, and one or two juices, moves faster through a self-serve line than a table crowded with eight options nobody has time to browse.

Adjusting for Meeting Length, Time of Day, and Attendee Mix

The 1.— baseline holds for a standard one-to-two-hour meeting. Outside that window, a few adjustments keep you from running short or overordering.

  • Long meetings (4+ hours): scale linearly with the formula, but add hot-drink refills at the two-hour mark rather than assuming one big urn will last the whole session.
  • Hot weather or summer bookings: bump water allocation by an extra 20 to 25%, since warm rooms and warm weather both drive up plain water consumption faster than any other category.
  • Morning vs. afternoon: mornings skew heavily toward coffee and tea; afternoons skew toward water and cold soft drinks as energy dips and people reach for something cooling instead of caffeinated.
  • Non-drinkers or light drinkers: if you expect a chunk of attendees to barely touch their allocation, build in a default 10% reduction on soft drinks rather than guessing per person.

None of these adjustments require a new formula, just a percentage tweak on top of the baseline you already calculated.

Getting the Logistics Right: Packaging, Cups, and Placement

The math only matters if the drinks actually reach people without slowing the meeting down. Container choice depends heavily on group size and how long the session runs.

  1. Individual bottles and cans work best for groups under 20 or meetings under two hours, since there’s no refill logistics to manage.
  2. Jugs and pitchers make sense for water in longer sessions where refilling once or twice is easier than stocking dozens of small bottles.
  3. Urns are the standard for hot drinks once you pass 15 to 20 attendees. A staffed coffee service can outperform a self-serve urn when the group is large enough that queuing becomes its own distraction.

Beyond the drinks themselves, don’t forget cups, lids, napkins, stirrers, ice for cold options, and a cooler or fridge access if drinks need to stay cold for several hours. Label anything dietary-specific, decaf, sugar-free, dairy-free milk alternatives, clearly enough that people don’t have to ask.

Pro Tip: Put water at the entrance, not the back of the room. People grab a bottle on the way in far more reliably than they’ll get up mid-meeting to find one.

Placement matters as much as quantity. A self-serve station near the door handles water and soft drinks fine, but hot drinks benefit from a staffed table when the group is large, since untrained hands around a hot urn slow everyone down.

Buffers, Rounding, and Handling Leftovers

Build in a 10% buffer on top of your calculated total as the standard rule, pushing to 15 to 20% for events where restocking mid-meeting isn’t realistic, remote offices, back-to-back bookings, or venues without a nearby shop. LocalCalcs’ event drink planning tool applies this same logic, converting raw servings into full packaging units rather than leaving you short a few bottles.

  • Round every total up to the nearest full pack, case, or urn fill. Never order a fraction of a case just to hit an exact number.
  • For hot drinks, round up to the next full urn cycle rather than estimating loose cups.
  • Leftover water and unopened cans can go into office fridges for staff use later in the week; opened hot drink urns should just get tossed.
  • Skip ordering perishable dairy-based extras you won’t use again if the leftover volume looks likely to be high.

Sample Order Templates by Meeting Size

Use these as starting points and adjust the mix based on the guidance above.

  1. Label water and soft drink stations separately from the hot drink table to avoid bottlenecks.
  2. Flag dietary swaps (decaf, plant-based milk, sugar-free options) directly on the order sheet before it goes to catering.
  3. If timing shifts from a half-day to a full afternoon, add another full hot-drink refill rather than recalculating from scratch, since the water and soft drink totals barely move.

For a related planning reference, check board meeting lunch ideas that pair food timing with these same drink windows.

What London and Surrey Meetings Taught Us About Ordering Drinks

The most common mistake we see is under-ordering water and treating hot drinks as an afterthought until the urn runs dry at hour three. Office Lunch Delivery has handled meeting catering across London and Surrey since 2015, and the pattern holds across nearly every booking size. One fix works consistently: confirm hot drink timing against the actual agenda, not the booking time, so refills land during breaks instead of mid-discussion.

How Theofficelunch Handles Drinks for Your Next Meeting

Ordering drinks separately from food usually means juggling two suppliers, two delivery windows, and two chances for something to arrive late. Theofficelunch bundles hot drink service, bottled water, and soft drinks directly into your catering order, so one delivery covers the whole meeting instead of a second scramble an hour before doors open.

That bundling matters most for recurring bookings, board meetings, half-day workshops, breakfast sessions, where the drink math changes every time but the ordering process shouldn’t. Labelled options for dietary needs come standard, so decaf, dairy-free, and sugar-free requests get sorted before delivery rather than sorted out in the room. If you’re planning a meeting in London or Surrey and want the drink counts handled alongside the menu, request a tailored quote through the office catering London page and get both sorted in one order.
