How many hours do you need a photo booth for at a wedding?

This is the question I get asked most, and the honest answer is that guest count and hours are related by arithmetic rather than by taste. Once you see the arithmetic the decision gets much easier.

How many people can actually use it in an hour?

One operator publishes their own average at about 25 sessions an hour, which they translate as roughly 75 sessions in three hours, 150 in six and 200 in eight.

A session is a group, not a person. Guests go in threes and fours at a wedding, more when a table decides to pile in together. So 75 sessions across a three hour booking covers a 150 person room comfortably, with plenty of people going in twice. At 250 guests the same booking starts to feel tight, and that is where a queue forms.

That is the whole reason the guidance scales with guest count rather than with how long your reception runs.

So how long should you book?

Published recommendations land in a fairly tight range. One operator recommends 2 hours for guest lists up to 75, calls 3 hours their most popular option, and suggests 4 hours for parties of 250 or more. Another puts weddings under 200 guests at 2 to 3 hours and over 200 at 4 or more, to avoid long lines and rushed photos.

A third says 3 to 4 hours covers most receptions comfortably, and that over 150 guests 4 to 5 hours gives everyone enough time without feeling rushed, while a fourth describes 4 hours as the most common and practical option, suited to 100 to 200 guests .

When in the night should it be open?

This matters more than the number of hours, and it is where the guidance genuinely splits.

the same operator suggests running the booth during cocktail hour as well as the dance reception . Their reasoning is good. Guests who are not planning to stay late get their turn during cocktails, and the wedding party gets one later, when they finally have fewer obligations.

Other guidance says to avoid running the booth during seated dinners or formal programme segments, because guests will not be using it anyway. That points to a single later block starting after the speeches.

Both are right about different weddings. If a chunk of your guest list is older or travelling and will leave after dinner, cocktail hour coverage is how they get included. If your guests are the sort who stay until the lights come up, a later block puts every booked hour where the energy is.

The bit people forget

one guide recommends opening the booth about 30 minutes after guests arrive , so people have a drink in hand and have found their group first. A booth that opens the moment doors open tends to sit quiet for the first stretch, then get busy anyway once people relax. You have paid for the quiet part either way.

Why the reception length is not the answer

A five hour reception does not mean you need a five hour booth. Those two numbers get conflated constantly, and they measure different things. The reception length tells you how long the room is occupied. The booking length needs to cover the hours guests are actually free to walk over, which is a smaller window inside it.

Subtract the seated dinner, the speeches, the first dance and the cake. On a lot of weddings that removes an hour and a half from the middle of the evening, and it is the part where a booth running costs money and returns nothing.

What if you want it closed during dinner?

That is what idle time is for. The booth stays set up and paused, then reopens after the speeches. It is charged at a lower hourly rate than active time, which makes a split schedule cheaper than booking straight through.

It also solves a practical problem. Packing down and setting up again in the middle of a reception is disruptive and takes longer than the gap usually allows. Leaving it in place and switching it off is quieter for everyone.

Worth checking with whoever you book: setup should happen outside your booked hours. If a company counts their own setup time against your rental, a three hour booking is really closer to two.

The honest part

More hours is not the fix for most problems. If your guest list is around 150, a five hour booking does not produce meaningfully more photos than a three hour one. It produces the same photos spread thinner, and a booth that is visibly quiet for long stretches.

The two cases where longer genuinely earns its keep are a guest list above 200, where the throughput arithmetic stops working, and a reception where you want cocktail hour covered as well as the dancing.

There is one exception worth knowing. a booth set up in a separate room from the reception may need a longer booking simply so guests can find it . I would treat that as a reason to move the booth rather than a reason to book more hours, and there is more on that in our post about where to put the booth at your reception.

What actually slows the queue

Not the number of guests, most of the time. It is the size of the groups going in. Three people take about as long as one, so a wedding where whole tables pile in together gets through the room faster than one where people go in pairs.

The other thing that slows it is guests waiting for their print before they move. That is why unlimited prints matter more than they sound: a group of six can each take a copy without anyone going back to the queue for a second turn.

Very large weddings

Above roughly 250 guests, adding hours stops being the efficient answer. The throughput is fixed at about 25 sessions an hour whatever you book, so a fifth hour buys another 25 sessions and nothing else.

At that size the better conversation is about the room. A booth guests can see from where they are standing gets used steadily all night. One tucked around a corner needs more hours to reach the same number of people, which is a more expensive way to solve a placement problem.

Where to start

Work out your rough guest count, then look at the table above rather than guessing. Decide next whether a meaningful number of guests will leave after dinner. If yes, budget for cocktail hour coverage with idle time in the middle. If no, a single block starting after the speeches will use every hour you pay for.
