An event is a different problem from a gift: you need to know how much film to buy, not just which camera. Every page here does the quantity maths as well as the pick.
For a wedding guest book, budget roughly one photo per two guests plus 20% spare, and use instax WIDE or instax SQUARE so there is room to write beside the picture. At 100 guests that is about 60 shots — three WIDE twin packs, around $66 of film.

Fujifilm instax WIDE 400
The wide print is the only format with enough room for a group shot and a handwritten message beside it, which is exactly what a guest book needs.

Instant cameras at events have become their own thing, and for good reason: a photo booth hire runs into the hundreds, and two instant cameras plus film does most of the same job for a fraction of it, with the prints going home in a book rather than to a cloud gallery nobody opens.
But an event is a planning problem, not a shopping problem. The question is never just which camera — it is how many shots you need, how much film that is, how many spare batteries, and what happens when a guest wastes four frames on the ceiling. Get the quantity wrong and you have forty guests and twenty exposures.
This is also the one part of the category where print size genuinely matters rather than being taste. A guest book needs room for the picture and room to write next to it. An instax mini print is credit-card size; a wide print is nearly twice that. At a wedding, that is the difference between a signature and a message.

Check priceHow to choose
Count the shots before you choose the camera
The rule that holds up: about one photograph per two guests, then add 20% for mistakes, double exposures and the people who take three. At 50 guests that is 30 shots, at 100 guests 60, at 200 guests 120. Then convert to packs — instax comes 20 to a twin pack, Polaroid 8 to a pack — and buy whole packs, because you cannot buy 7 exposures.
Use a format with writing room
instax WIDE at 3.9 x 2.4 inches and instax SQUARE at 2.4 x 2.4 both leave usable space in a book beside the print. instax mini works if the book has space for a message underneath. Full-size Polaroid is the most impressive print and, at about $2.37 a shot, by far the most expensive way to fill a guest book — 60 photos of i-Type film is around $142 against roughly $66 of instax WIDE.
Plan for the camera being used by strangers
- Pick the simplest camera you can. A guest who has to work out a mode dial will not bother, and the ones who do will waste film learning.
- Write instructions on a card. Three lines, next to the camera. 'Twist the lens to turn on. Press the big button. Leave the photo face-down for 90 seconds.'
- Buy spare batteries and keep them with the camera. An instax mini 12 does about 100 shots per set of AAs, which is fine for one wedding and not for two.
- Have two cameras if there are over 100 guests. One camera is a queue, and a queue is why half your film goes unused.
- Say where the photos go. A labeled box or an open book with a glue stick beside it. Prints left on a table go home in pockets.
Consider a printer as the second half of the setup
A popular combination is one instant camera for the guest book plus a pocket printer so guests can print the photos from their own phones. The printer costs about 42 to 60 cents a print rather than $1.10, so it absorbs the volume while the camera handles the ceremony of it.

Occasions: questions people ask
What is the best instant camera for a wedding guest book?
An instax WIDE 400 or an instax SQUARE SQ40. Both make a print big enough to sit beside a handwritten message, both are simple enough for a guest who has never used one, and the film costs about $1.10 to $1.15 a shot against roughly $2.37 for full-size Polaroid.
How many photos do I need for a wedding guest book?
Plan one photo per two guests plus about 20% spare. For 100 guests that is roughly 60 shots, which is three 20-exposure instax twin packs. Buy whole packs and expect some waste — guests double-expose, miss the subject, and occasionally photograph the floor.
How do you set up a Polaroid guest book?
Put the camera, spare film, a glue stick or photo corners, two pens and a short instruction card on one table with the book open. Leave a sample page already filled in so guests copy the format, and nominate somebody to check the camera every hour — film running out unnoticed is the usual failure.
Is an instant camera cheaper than a photo booth?
Usually, yes. Two instax cameras and 120 shots of WIDE film is roughly $350 to $400 all in, and you keep the cameras afterwards. Photo booth hire is typically several hundred dollars for a few hours with nothing to keep. The booth gives you props, prints on demand and somebody else running it.
Should guests use the camera or print from their phones?
Both, if you can. The camera is the thing people enjoy, and the ceremony of handing over a developing print is the point. A pocket printer alongside it absorbs the volume at a lower cost per print and catches the photos guests took on their own phones, which are usually the better pictures anyway.
