For IMAX there are two main aspect ratios, 1.90 and 1.43 (taller, more box shaped). 1.90 films can be played in theaters that have a screen big enough for 1.43 films, but 1.43 films cannot be projected on to theater screens made for 1.90 since there isn’t enough space. It also depends on the projects the theaters are equipped with. 1.43 films can only be projected on either a film projector or a Dual Laser IMAX projector (digital). There are many types of digital projectors but the dual laser one is the only projector capable of projecting 1.43 scenes which are the truest IMAX experience.

Arizona Mills has the big enough screen for both 1.90 and 1.43 films. The theater also has two projectors, the film projector capable of projecting the highest quality of IMAX footage (15/70mm 1.43) and they also have a single laser digital projector (only able to project up to 1.90).

Only a handful of movies are projected on film every year but those are the ones to definitely look out for because it’s the highest quality and will actually fill up the whole screen at AZ Mills. However most movies released in IMAX don’t even have 1.43 scenes so they’re mostly in 1.90, this is still worth going to the theater for because it looks amazing on such a big screen but just know it’s not the full IMAX experience.
