Rack length is arithmetic, staffing is the trap
Four hundred guests, seventy percent checking, 1.4 items each is 392 items. At two and a half inches a hanger that is 81.7 feet of hanging, and on a double bar rack it is 40.8 feet of floor run — nine sections of five feet, three runs of twenty. With two feet of rack and three feet to work in behind it, the coat room is 300 square feet. All of that is multiplication and none of it is where coat checks fail.
They fail on the way out. Taking 392 items in at twenty seconds each, spread over a forty minute arrival window, needs four attendants. Handing the same 392 back at thirty-five seconds each inside a twenty minute departure window needs twelve. Same night, same items, three times the people, and almost every venue staffs the number the door needed.
Why giving back is slower than taking in
Taking a coat is one motion: hanger, tag, hang, hand over the stub. The attendant is standing at the head of the rack and never moves. Giving it back means reading a number, walking to wherever that number lives, finding it among a hundred near identical black coats, and walking back. The walk is most of the difference and it grows with the length of the run, which is why the number nobody thinks about is not the spacing but the sectioning.
Put a letter on the tag and split the racks into lettered sections, and the walk collapses. It is the cheapest improvement available to a coat check and it costs a box of tags. Nothing on the form models the gain because it depends entirely on how the room is shaped, but if the page is telling you to hire twelve people, section the rack and re-time it before you do.
The three attendants in the field
They are there to show what actually happens. Three people at thirty-five seconds an item clear 392 items in 76 minutes. The event ends, everyone stands up, and the last coat goes over the counter an hour and a quarter later. That is not a hypothetical — it is the queue that snakes past the bar at every winter function, and it is fully predictable from three numbers on a spreadsheet the week before.
Spacing changes everything and nobody measures it
Two and a half inches assumes ordinary jackets pressed together. Wool overcoats want four, and at four inches the same 392 items need 65 feet of double bar run instead of 41 — five more sections and probably another run in the room. Take a tape to a packed rack in the season you are actually working, because the difference between a summer wedding and a February gala is a different room.
The other spacing question is honest capacity against pretty capacity. A rack packed to the arithmetic is a rack where coats are hard to pull, which lengthens the retrieval time and feeds straight back into the staffing sum. If you pack tight, put the seconds up.
What it costs to give it away free
Three attendants for six hours at twenty-two dollars is 396 dollars, which is about a dollar an item across 392 items. Charge three dollars and the coat check makes 1,176 and clears 780 after labour, before hangers, tags and the floor the room is taking. Charge nothing and it is a 396 dollar line on the event budget that most people never write down. The page prints the break-even fee for exactly that reason.
Questions people ask
How many coats fit on a foot of rack?
Divide twelve by your hanger spacing. At two and a half inches that is 4.8 coats a foot on a single bar and 9.6 on a double bar rack, so 392 items want about 41 feet of double bar run. The spacing is the whole answer and it moves a long way with the season — four inches for winter overcoats drops it to three a foot on a single bar.
How many attendants does a coat check need?
Work the end of the night, not the door. At the values in the form the arrival window needs four and the departure window needs twelve, because giving a coat back takes longer than taking it and happens in half the time. Staffing to the door figure is the standard mistake and produces the queue everyone recognises.
Why is the line at the end so much worse than at the start?
Two things multiply. The transaction is slower, because someone has to walk the rack and find one tag among hundreds. And the window is shorter, because a room empties in about twenty minutes while it filled over an hour. Slower work in less time, on the same number of items.
How much floor does a coat room take?
Runs times run length times the rack depth plus your working space. At the defaults that is three runs of twenty feet, each two feet of rack and three feet to stand in, so 300 square feet. The working space is a figure you set for your own staff — it is not an aisle width or an egress dimension, and neither of those comes from this page.
Should the coat check be free?
That is a budget decision rather than an arithmetic one, but the page gives you the number to make it with. Three attendants for six hours at twenty-two dollars an hour is a dollar an item in labour alone. Whether that lands on the guest or on the event is the question, and it is worth answering deliberately rather than by default.
