How to size a commercial ice machine
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
- Count peak-day guests, seats, rooms, or iced drinks — not a quiet Tuesday.
- Multiply by the starting point in the table.
- Add prep, display, bagged, and catering ice as separate lines.
- Add a 15–25% reserve for weather, a festival weekend, or a dirty condenser.
- 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.
