>>3413481>>3413482Yeah, Instax actually comes in three sizes: Mini, Square, and Wide.
Mini are the little rectangles you're thinking of when you think Instax. The Instax Square film is basically just Mini with a little extra on the edge to make it 1:1, so it's still noticeably smaller than 600-style Polaroid.
Instax Wide is about the same area as 600-style polaroid, but rectangular instead of square.
There's also Polaroid Spectra, which I think is like 600 but wider, so probably the biggest of the bunch.
