How to size a commercial ice machine

Updated 2026-10-02. Independent guide — not a dealer quote.

Commercial ice machines are sold by pounds of ice in 24 hours, not by “small / medium / large.” Manufacturer “up to” numbers are measured at about 70°F air and 50°F inlet water. In a 90°F kitchen with 70°F water, the same machine often makes 15–30% less. Ice-O-Matic, Scotsman, and Manitowoc publish both conditions on most current sheets; use the 90/70 column if the machine will live next to a range.

This page is a planning table, not a code calculation and not a dealer quote.

Work the number, then add a buffer

  1. Count peak-day guests, seats, rooms, or iced drinks — not a quiet Tuesday.
  2. Multiply by the starting point in the table.
  3. Add prep, display, bagged, and catering ice as separate lines.
  4. Add a 15–25% reserve for weather, a festival weekend, or a dirty condenser.
  5. Compare the total to the machine’s 90/70 production if you have it; otherwise assume you will not get the brochure “up to” number.

A bin that holds 60–80% of a day’s make is a common planning range on this page; published dealer shortcuts actually span a wider band. Size the leftover around the rush window — see ice bin sizing. A short Sunday-service spike cares more about bin pounds than 24-hour rating.

Venue table (lbs / day)

Figures below are published application rules of thumb, not lab measurements. Sources are listed under the table. Your menu will move the number.

Venue Published starting point Example (peak day) Rough target before reserve
Cafe / coffee shop / espresso bar Atlantic 0.35–0.6 lb per iced beverage (weigh the cup); Light Soda 1–1.5 lb per customer if almost every ticket is iced. Kitchen Spot coffee/smoothie 2.5 lb/person is the blender page 80 iced drinks × 0.5 lb = 40 lb; 300 × 0.45 (Atlantic café cup test) = 135 lb Size the leftover for the morning iced-latte window; product shortlist stays on the undercounter cafe page
Cocktail bar ~3 lb per seat on a busy night; some guides use 3–4 lb per customer 40 seats × 3 lb = 120 lb 150–250 lb after buffer; high-volume cocktail programs go higher
Nightclub Ice Machine Sales nightclub 2 lb per person. Not their cocktail 3 lb, craft cocktail 4 lb, or beer-and-wine 1 lb. Atlantic’s combined “bar or nightclub” cell is about 3 lb per seat — that is their bar line, not the 2 lb row. FAQ: typically 400–1,000+ lb per night. Several bars: undercounter at each station plus a modular head in back-of-house 300 guests × 2 lb = 600 lb; Kitchen Spot’s own +20% once = 720 lb Multi-station nightlife. Do not copy the cocktail bar’s 3 lb seat math, or the 200-guest cocktail example (≈ 600 lb), onto this headcount
Beer-and-wine bar / brewery taproom ~1 lb per person (Kitchen Spot beer & wine bar). Charts do not publish a brewery guest factor 80 guests × 1 lb = 80 lb Guest/service ice only; cocktail wells and plated covers are separate lines
Full-service restaurant ~1.5 lb per guest 80 covers × 1.5 lb = 120 lb Add bar, salad bar, and fish display as extra lines
Quick service / smoothie 0.5–1.0 lb per customer, or drink-size rules (e.g. 16 oz ice in a 32 oz cup) 300 guests × 0.75 lb = 225 lb Modular heads show up quickly once fountain volume grows
Food truck Rarely published as a per-guest factor; power and water dominate Lunch + dinner iced drinks + a well Many trucks run 50–150 lb self-contained units on 115 V
Church / banquet kitchen ~1–1.5 lb per person at the event, plus leftover for coffee service 200 people × 1.25 lb = 250 lb Size the bin for the service window, not just 24 h make
Hotel guest ice ~5 lb per occupied room 80 rooms × 90% × 5 lb = 360 lb Restaurant, bar, breakfast, and banquet are separate machines or a larger plant
Banquet hall / wedding venue / ballroom GoFoodservice Event Hall / Banquet 2 lb per attendee (quick-reference cells already include +20%). Alternates, not an average: Atlantic catering or banquet 1–1.5 lb/attendee; Manitowoc / ZESCO catering 1 lb/person; Kitchen Spot hotel catering 1 lb, general 1.5 lb, extended events 2 lb 200 attendees × 2 lb = 400 lb; their +20% calculator = 480 lb Fixed hall sized by attendees. Size the bin for the dinner window, not only 24 h make. Not off-site catering and not guest-floor ice
Country club / golf club / private club Charts do not print a country-club lb row. Sum separate published lines: dining Kitchen Spot / Atlantic / KaTom 1.5 lb per guest (or GoFoodservice restaurant 2 lb); cocktail lounge ~3 lb per seat; beer-and-wine 1 lb per person (do not stack on 3); on-site banquet GoFoodservice 2 lb per attendee (cells already +20%). Pool: Kitchen Spot / GoFoodservice oz per cup, or Atlantic QSR 0.5–1.0 lb, or Ice Machine Sales concession 2 lb — pick one. Fitness 1 lb/member and hotel 5 lb/room only if those departments exist 120 grill × 1.5 lb = 180 lb; 40 cocktail seats × 3 lb = 120 lb; 200 banquet × 2 lb = 400 lb; sum 700 lb before each source’s own buffer Grill + lounge + ballroom. Do not invent a club factor. Do not stack Kitchen Spot’s 20%, GoFoodservice’s already-included 20%, and a hot-room derate on the same pounds
Marina / yacht club / specialty marine Kitchen Spot commercial ice machine sizes chart and Ice Machine Sales sizing chart: Specialty Marine 3.5 lb per person. Kitchen Spot’s chart says add 20%. Not a country-club campus sum, not cocktail 3 lb/seat, not beer-and-wine 1 lb, not hotel 5 lb/room, not restaurant 1.5 lb/guest. Boat-cooler bags are GoFoodservice 10 lb × bags, a separate line 80 people × 3.5 lb = 280 lb; Kitchen Spot +20% once = 336 lb Ship store, yacht club bar or galley, dockside snack. Do not stack bags on the 3.5 line. Not a food-truck power/tank worksheet
Office break room ~1.5 lb per employee is one published office figure; many offices are far lower 25 people × 1.5 lb = 38 lb Compact undercounter or a small top-hat / cubelet unit
School cafeteria / campus dining ~1 lb per student per meal period (Kitchen Spot / Ice Machine Sales / KaTom); Hoshizaki / GoFoodservice 1.5 lb/student (university often the 1.5 band) 250 students × 1 lb = 250 lb Size the bin for the lunch window; athletic 5–10 lb/athlete is a separate line
Gym / fitness / athletic training Ice Machine Sales fitness center 1 lb/member; athletic training 5 lb (education) to 10 lb (sports) per athlete; concession 2 lb/customer 80 members × 1 lb = 80 lb Split member drinks, trainer packs, ice baths, and concession — do not stack
Catering company / off-site events Manitowoc / ZESCO 1 lb/person; Atlantic banquet 1–1.5 lb/attendee; Kitchen Spot hotel catering 1 lb, general 1.5 lb, extended 2 lb. Event serving ice is Chef’s Deal 0.5–0.75 lb/guest/hour — tubs and displays are separate 80 guests × 1.5 lb = 120 lb Commissary make vs event-day bag-out vs bags; do not stack per-attendee and per-hour rows
Hospital / patient floors GoFoodservice / Tundra / HVACDirect hospital patient ice 10 lb/bed; healthcare cafeteria 1 lb/person is a separate line. GoFoodservice’s 50-bed hospital cell is 600 lb (10 lb already +20%). Nursing-home 6 lb/bed is the nursing home page 50 beds × 10 lb = 500 lb Patient floors vs staff cafeteria; do not copy 6 lb/bed onto a hospital and do not copy 10 onto a nursing home
Nursing home / assisted living / long-term care GoFoodservice nursing home patient ice 6 lb/bed (quick-reference cells already include +20%: 50 beds 360 lb, 100 720 lb, 250 1,800 lb, 500 3,600 lb). Kitchen Spot nursing homes 6 lb per resident (+20%). KaTom about 6 lb per patient bed (their 100-customer nursing-home cell is 720 lb, already +20%). Healthcare cafeteria 1 lb/person is a separate line. Not hospital 10 lb/bed 50 beds × 6 lb = 300 lb; GoFoodservice buffered cell 360 lb Assisted living, memory care, and skilled nursing use this 6 lb row when that is the published match. Do not average 10 and 6
Seafood market / fish counter Atlantic: measure actual display fill plus daily replenishment. GoFoodservice supermarket flake display 27 lb/ft³ to fill (cubed display 32 lb/ft³). Freezer Supply: receiving vs display vs packing vs outbound; peak overlap drives sizing 2.0 ft³ well × 27 lb/ft³ = 54 lb initial fill Flake for the bed and totes, not restaurant 1.5 lb/guest; drink ice is a second system
Grocery store / supermarket Atlantic: measure actual display fill plus daily replenishment. GoFoodservice supermarket flake display 27 lb/ft³ to fill (cubed display 32 lb/ft³). Kitchen Spot / KaTom grocery 35 lb/ft³. Fountain cups and 10 lb × bags are separate cube lines 2.0 ft³ produce well × 27 lb/ft³ = 54 lb initial fill Produce / meat / seafood / salad flake vs fountain / bagged cube — two ice forms → two systems; not a c-store-only page
Deli / sandwich shop Charts do not publish a lb-per-sandwich. Closest: Atlantic QSR 0.5–1.0 lb/customer or Kitchen Spot / GoFoodservice fountain oz/cup; salad-bar 30–35 lb/ft³ if there is a well; restaurant 1.5 lb only for plated dine-in. Bags optional 10 lb × bags 150 × 16 oz cups × 8 oz ice = 75 lb fountain Fountain + iced drinks + optional salad-bar flake; not grocery produce flake, not bakery dough, not c-store bags-only
Movie theater / cinema concession Charts do not publish a lb-per-seat cinema row. Closest: Kitchen Spot / GoFoodservice / Memphis fountain oz/cup or Atlantic QSR 0.5–1.0 lb/customer; Ice Machines Sales concession 2 lb/customer is a sports/entertainment stand row — do not stack it on the ounce line. Bags optional 10 lb × bags 200 × 16 oz cups × 8 oz ice = 100 lb fountain Show-block fountain + iced drinks; size the leftover for pre-feature / intermission, not restaurant 1.5 lb/seat
Stadium / sports arena / concert venue Charts do not print a stadium lb/seat row. Sum separate published lines: concessions Ice Machine Sales 2 lb per customer (or Kitchen Spot / GoFoodservice oz per cup, or Atlantic QSR 0.5–1.0 lb — pick one); VIP suites 3 lb per guest; optional training room 10 lb per athlete. Fitness 1 lb/member is a different department. Easy Ice prints event-day / modular / bin framing and no lb/customer factor 400 concession customers × 2 lb = 800 lb; 40 suite guests × 3 lb = 120 lb; sum 920 lb before Kitchen Spot’s own 20% buffer. Optional 30 athletes × 10 lb = 300 lb Event day. Seat count is not customer count. Do not stack ounces on the 2 lb line, suite guests on the concession line, or 10 lb/athlete on 1 lb/member
Juice bar (cold-pressed / iced juice) Charts do not publish a lb-per-juice row. Iced cups: Kitchen Spot 6 oz/12 oz or 8 oz/16 oz, or Atlantic 0.35–0.6 lb after a cup test. Sealed bottles and shots are zero ice. Kitchen Spot coffee/smoothie 2.5 lb/person is the blender page 55 iced cups × 8 oz ice = 27.5 lb; 45 bottles add nothing Morning-to-lunch cup fill; not a smoothie jar, not a boba 24 oz shaker
Ice cream shop Charts do not publish an ice-cream-shop or lb-per-cone row. Floats and fountain: Kitchen Spot oz/cup or Atlantic café 0.35–0.6 lb, or QSR 0.5–1.0 lb/customer. Shakes: Kitchen Spot coffee/smoothie 2.5 lb/person only on blender dumps. Hard-pack scoops are zero ice. Ice Machines Sales concession 2 lb/customer only without a cup count — do not stack. Cold-prep is measured 40 × 16 oz floats × 8 oz ice = 20 lb; 180 hard-pack scoops add nothing Cube or nugget for shakes, floats, and fountain; not a soft-serve or gelato freezer

Worked cafe

A 32-seat cafe sells about 180 iced drinks on a hot Saturday and uses ice in a few cold-brew kegs.

  • Drinks: 180 × 0.5 lb ≈ 90 lb (cafe range 0.35–0.6 lb/drink from application guides).
  • Staff / overflow: 15 lb.
  • Subtotal 105 lb. Reserve 20% → about 125 lb/day.

That is an undercounter job if the bin is large enough for the afternoon rush. Full espresso-bar sizing — morning leftover, heat next to steam wands, and when Atlantic’s 220–250 lb café shop band leaves undercounter class — is on ice machine for a coffee shop. Product shortlist: best undercounter for a cafe and the directory.

Worked cocktail bar

A 48-seat cocktail bar, one well, no restaurant.

  • 48 × 3 lb = 144 lb.
  • Bottle wells and a second garnish station: +40 lb.
  • Reserve 25% → about 230 lb/day.

Gourmet cubes melt slowly but machines that make them are small (often 50–65 lb/day). Many bars run a gourmet undercounter at the well and a half-dice or crescent machine in the back. Venue sizing (lbs/day, bin, form factor) is on ice machine for a bar. Ice type and melt stay on best ice for a cocktail bar. A nightclub on Ice Machine Sales’ 2 lb per person row — not this 3 lb seat example — is ice machine for a nightclub.

What the rating does not include

  • Air-cooled machines need intake and discharge clearance. A boxed-in louver is a derate.
  • Water-cooled machines use extra condenser water; many cities restrict them. See air-cooled vs water-cooled.
  • Soft water, a clogged filter, or skipped descaling cuts harvest. See filters and descalers.
  • Voltage: a 115 V cord-and-plug undercounter is not the same electrical job as a 208–230 V hardwired modular head.
