Instax Film in a Polaroid: Compatibility, the Real Answer
No, Instax film does not work in a Polaroid (nor the other way round). Dimensions, chemistry, power supply: why the formats are incompatible, plus the complete film ↔ camera table so you never buy wrong again.

Criteria to evaluate
Physical format
essentialEach cartridge only fits mechanically into cameras of its own format.
Power supply
essentialThe battery is in the cartridge (Polaroid 600), in the camera (i-Type) or in the camera via batteries (Instax): mixing them is impossible.
Chemistry and speed
importantInstax (ISO 800) and Polaroid (ISO 640) use different, non-interchangeable chemistries.
Instax Film in a Polaroid: Why It Doesn't Work (and What to Buy Instead)
The question comes up constantly, often after a failed purchase: can you put Instax film in a Polaroid camera? No — in neither direction, in no format. This isn't about closed brands or marketing: the two systems differ in cartridge size, chemistry, film speed and even how the camera is powered. Here's the detail, and the table to never get it wrong again.
Why the two systems are incompatible
1. The dimensions don't match
An Instax Mini film measures 54 × 86 mm; a classic Polaroid film, 88 × 107 mm. An Instax cartridge won't even lock into a Polaroid, and vice versa. The ejection mechanisms are sized for their own format.
2. The chemistry is different
Instax and Polaroid don't use the same development process. The chemical layers, the reagents and the ejection direction (the Instax image develops from the top of the print, the Polaroid from the front) are specific to each system. Even at equal size, one wouldn't develop the other.
3. The speed differs
Instax films are ISO 800 emulsions; Polaroid i-Type/600 are ISO 640. Cameras are calibrated for their own film speed — exposure, flash and development are set accordingly.
4. The power supply isn't in the same place
This is the least-known and most blocking point:
- Instax: the batteries are in the camera (AA or CR2 depending on the model); the film carries no power.
- Polaroid i-Type: the rechargeable battery is in the camera; the film has no battery.
- Polaroid 600: the battery is inside each film cartridge — it's what powers vintage cameras that have no battery of their own.
Three different electrical architectures: no mixing is possible.
The complete film ↔ camera compatibility table
| Film | Dimensions (image) | Speed | Battery | Compatible cameras |
|---|---|---|---|---|
| Instax Mini | 54 × 86 mm (62 × 46 mm) | ISO 800 | In the camera | Instax Mini 11, 12, 40, 99, Evo; Mini Link printers |
| Instax Square | 86 × 72 mm (62 × 62 mm) | ISO 800 | In the camera | Instax Square SQ1, SQ40; Square Link printers |
| Instax Wide | 86 × 108 mm (99 × 62 mm) | ISO 800 | In the camera | Instax Wide 300, 400; Link Wide printers |
| Polaroid 600 | 88 × 107 mm (79 × 79 mm) | ISO 640 | Battery in the cartridge | Vintage Polaroid 600 cameras and i-Type cameras |
| Polaroid i-Type | 88 × 107 mm (79 × 79 mm) | ISO 640 | No battery | Polaroid Now, Now+, I-2, Lab — never vintage 600s |
| Polaroid Go | 66.6 × 53.9 mm (47 × 46 mm) | ISO 640 | No battery | Polaroid Go only |
Two traps to remember from this table:
- 600 film works in i-Type cameras (Now, Now+, I-2), but i-Type film does not work in vintage 600 cameras — with no battery in the cartridge, the camera won't even switch on.
- The Polaroid Go only accepts Go film, a mini format specific to that camera. Neither i-Type nor 600.

The most common buying mistakes
"I bought i-Type for my grandfather's old Polaroid"
The vintage camera doesn't switch on: it has no battery and waits for the cartridge's battery. Solution: exchange the pack for 600 film. It's the #1 mistake with second-hand cameras.
"I got Go film because I have a Polaroid"
Go film only fits the Polaroid Go. A Now or Now+ needs i-Type (or 600). The "Go" name confuses many buyers.
"I mixed up Instax Mini and Instax Square"
Same brand, nearly the same box colour, but Square (86 × 72 mm) doesn't fit a Mini. At Instax as at Polaroid, the rule is absolute: the film name must exactly match the camera name.
"I bought Wide to take bigger photos with my Mini 12"
Wide doesn't fit a Mini — for large format at Fujifilm, you need a Wide camera (Wide 300, Wide 400) and its dedicated film.
The golden rule before any purchase
Look at the exact name written on your camera and only buy film that carries exactly the same format name:
- Instax Mini → Instax Mini film
- Instax Square SQ1/SQ40 → Instax Square film
- Instax Wide 300/400 → Instax Wide film
- Polaroid Now/Now+/I-2 → i-Type film (or 600)
- Vintage Polaroid 600 → 600 film only
- Polaroid Go → Go film only

No. The Instax Mini cartridge (54 × 86 mm) is physically too small and differently shaped from the Polaroid format (88 × 107 mm). It won't lock into the camera, and even forced in, the chemistry, speed and ejection system are incompatible.
Same size, same chemistry, but 600 film contains a battery in each cartridge to power vintage cameras that have none, while i-Type film doesn't — it's designed for recent cameras with a rechargeable battery (Now, Now+, I-2). 600 film works in i-Type cameras; the reverse is not true.
No. Vintage Polaroid 600 cameras have no internal battery: they draw their power from the battery built into 600 cartridges. i-Type film, with no battery, can neither power the camera nor eject photos. A vintage 600 absolutely requires 600 film.
No. The three Instax formats have different dimensions and are not interchangeable: a Mini camera only takes Mini, a Square only Square, a Wide only Wide.
No. The Go format (66.6 × 53.9 mm) is specific to the Polaroid Go. The Now and Now+ use i-Type or 600 film in the classic format (88 × 107 mm).
If the packaging is still sealed, most retailers accept a return or exchange. Keep the film in its original box, somewhere cool, and check the seller's return policy. Once the cartridge is opened or inserted, a return becomes very difficult.
