How Many Instax or Polaroid Films for a Wedding? (2026 Calculation)

How Many Instax or Polaroid Films for a Wedding?

Film is the most underestimated item in the whole photo organisation of a wedding. The camera, you buy once. But on the night itself, at 10 PM, when the cartridges are empty and the party is in full swing, there's nothing left to negotiate: either you planned enough, or the entertainment stops dead.

This guide gives you the calculation rule, the tables by guest count, and how the formats compare. Pack counts do not depend on the day's price. Retailers including Amazon, Fnac and Boulanger change their prices, so verify them when ordering.

This guide is part of our instant photography wedding hub, which covers the whole organisation of the big day.

The calculation rule (copy it as-is)

Number of guests × photos per guest × 1.2 = films to order.

• Photos per guest: 2 if your crowd is on the reserved side, 3 for a classic wedding, 4 if your guests are the festive type (or if the cameras circulate in self-service all evening).
• The 1.2 coefficient: that's the 20% margin. It absorbs failed shots, accidental triggers, guests who "try one last one" — and there are always some.

Example: 100 guests, classic level → 100 × 3 × 1.2 = 360 films. Round up to the next pack size (for example 4 packs of 100).

Why not less? Because the cost of a shortage is disproportionate: the entertainment dies in the middle of the evening to save the price of two or three twin packs. And unopened films don't go to waste — they keep for 1 to 2 years in a cool place.

Tables by guest count

Number of films to order (20% margin included)

Guests	2 photos/guest	3 photos/guest	4 photos/guest
50	120 films	180 films	240 films
100	240 films	360 films	480 films
150	360 films	540 films	720 films
200	480 films	720 films	960 films

Add 30 to 60 wide-format films (Instax Wide or Polaroid) if you set up a DIY photobooth: the attraction concentrates the visits and guests often retry several times.

Film budget by format (3 photos/guest, margin included)

The guest-count table above is the quantity. The money follows the format:

Format	Same guest count, versus Instax Mini
Instax Mini	The baseline
Instax Wide	About 30 percent more
Polaroid i-Type	About two and a half times

The conclusion is clear: in volume, Polaroid i-Type costs about two and a half times Instax Mini. That's why the setup we recommend in our comparison of cameras for weddings reserves Polaroid for the photobooth and puts Instax Mini on the tables.

Your wedding doesn't fit these four rows? Change the guest count, the photo pace and the format. The calculator applies the × 1.2 margin and gives you the quantity to buy.

The cost per photo, format by format

Instax Mini — per photo

The most economical format on the market. The 20-shot twin pack is the usual buy; a single 10-shot pack costs more per shot. In packs of 50 or 100, the price per photo drops further. It's the volume format: reception tables, guest book, general entertainment.

Instax Wide — per photo

Almost twice the surface of a Mini (99 × 62 mm): the format for group photos and the photobooth. The 20-shot pack varies a lot between retailers — compare, the gap is real. It costs more per shot than Mini, so you don't put it on every table, but it's unbeatable for fitting 4-5 people in the frame.

Polaroid i-Type — per photo

The iconic white-framed square format — and the most expensive. Even in bulk, a shot costs about two and a half times Instax Mini. The 40-photo pack spreads the order into one box and avoids several small purchases. Reserve it for the photobooth or a premium guest book, not for volume.

Polaroid Go and Instax Square — the special cases

Polaroid Go sits about one and a half times a Mini shot. Instax Square sits a little above Mini. Usable, but neither beats the Mini on volume nor the Wide on group rendering: for a wedding, they remain niche choices.

Three complete budget scenarios

Scenario A — 60 guests, all Instax Mini

• 60 × 3 × 1.2 = 216 → 240 films (2 packs of 100 + 2 twin packs)
• Film: a stack of twin packs, since Mini film is the cheapest per shot
• The most frugal scenario, perfect for an intimate wedding.

Scenario B — 100 guests, Mini on the tables + Wide photobooth

• Tables: 100 × 3 × 1.2 = 360 Mini films
• Photobooth: 40 Wide films
• The Wide booth is a small share of the film budget next to the Mini tables.

Scenario C — 150 guests, Mini + Polaroid photobooth

• Tables: 150 × 3 × 1.2 = 540 Mini films
• Photobooth: 48 Polaroid i-Type films
• The Polaroid booth adds roughly a fifth on top of the Mini tables, because each Polaroid shot costs about two and a half times a Mini shot.

These counts cover only the films. Cameras, guest book and accessories are costed in the wedding pillar guide, and the photobooth budget is detailed in our DIY wedding photobooth guide.

Buying in bulk: the tips that lower the bill

Aim for packs of 50 or 100

The price per photo drops by 15 to 25% between the 10-shot pack and the 100-shot pack. For a wedding, the question isn't "will I use it all" but "which pack size covers my table above". The surplus keeps.

Watch for sale periods

Prime Day (July), Black Friday (November), seasonal sales and flash sales: Instax film packs are regularly discounted. If your wedding is in September, buying in July can make a real difference on 360 films. The details of the periods and tricks: our guide how much does an Instax Mini film cost.

One format everywhere, except at the photobooth

Multiplying formats multiplies the risks: a Wide cartridge loaded into a Mini, the wrong pack purchased, scattered stocks. One format for the tables (Mini), one format for the photobooth if you insist (Wide or Polaroid). Two formats maximum.

Check the expiry date on delivery

Every box carries a date, generally ~2 years after manufacture. Demand at least 6 months of remaining validity, test one cartridge per batch on arrival, and send back any doubtful batch immediately. Beware of third-party sellers with abnormally low prices.

Store cool, take out in advance

Unopened films: cool place (5-20 °C), dry, away from light — the fridge works, never the freezer. Take the cartridges out 1 to 2 hours before use: a cold film gives washed-out prints.

What about unused films?

They won't be wasted. An unopened film, properly stored, lasts 1 to 2 years. Between birthdays, end-of-year celebrations and simple Sundays, the remaining stock will go much faster than you imagine. That's exactly why the 20% margin isn't waste: it's insurance.

Final word

The calculation fits in one line: guests × 3 × 1.2. The economical format fits in one word: Instax Mini for volume, wide format reserved for the photobooth. And the smart purchase fits in one habit: packs of 100, bought on sale, 3 to 4 weeks before the big day.
