What is IMAX?
IMAX is a premium cinema format that delivers a larger, sharper, and more immersive movie experience. Compared to a standard theater, IMAX uses larger screens, brighter projectors, powerful surround sound, and specially optimized movies.
IMAX Formats
1. IMAX with Laser ⭐ (Best Digital)
Dual 4K laser projectors
Brighter image
Higher contrast with deeper blacks
12-channel surround sound
Supports taller IMAX aspect ratios
This is the best digital IMAX experience available today.
2. IMAX Xenon (Digital IMAX)
Older dual 2K projectors
Good image quality
Smaller screens than Laser IMAX
Less brightness and contrast
Many older IMAX theaters still use this system.
3. IMAX 70mm Film ⭐⭐⭐
Uses giant 70mm film instead of digital projection
Extremely high image resolution
Very few theaters in the world still support it
Often used by Christopher Nolan films
Many movie enthusiasts consider this the ultimate IMAX experience.
Aspect Ratios
An aspect ratio describes the shape of the movie image.
Aspect Ratio | Common Usage | Extra Picture |
2.39:1 | Standard widescreen movies | Baseline |
1.90:1 | Digital IMAX | ~26% more image vertically |
1.43:1 | Full IMAX / IMAX GT | ~40% more image vertically |
When a movie is Filmed for IMAX, selected scenes expand to a taller ratio so you can see more of the original image.

📽️ If neither is available, IMAX Xenon is still an upgrade over a standard cinema.
