Find Your Ideal Cinema Viewing Distance
The right distance from a cinema screen depends on two things: how wide the screen is, and how much of your field of view you want it to fill. Use the calculator below, then read on for the standards behind it.

Rule of thumb: most people prefer sitting 1.5-2× the screen width back. Below ~1× the image overruns your vision; beyond ~3× immersion drops off.
The Simple Geometry Behind It
Viewing distance follows directly from trigonometry. For a screen of width W and a target horizontal viewing angle θ, the ideal distance is:
The formula
A wider target angle means a more immersive (closer) seat; a narrower angle means a more relaxed (further) seat.
THX and SMPTE Recommended Angles
Two industry bodies publish seating guidance. SMPTE sets a minimum; THX targets a more immersive angle for the best seat in the house.
| Standard | Target angle | Feel |
|---|---|---|
| SMPTE minimum | 30° | Acceptable, back-of-house |
| THX recommended | 36° | Immersive sweet spot |
| Enthusiast | 50° | Highly immersive |
| IMAX-like | 70°+ | Fills peripheral vision |

The Quick Rule of Thumb
If you don't want to do the math: sit 1.5 to 2 times the screen width back. On a 16m screen that is 24-32m; on a giant 22m IMAX screen it is 33-44m - which is why IMAX best seats sit higher and further back than in a standard hall. Compare screen sizes in our screen size guide.
Stop Calculating - Start Previewing
A number is useful, but seeing it is better. CinemaView's 3D seat simulator computes the viewing angle for every seat in IMAX, Dolby Cinema, ScreenX and 4DX, and shows you the screen from each one - so you can book with confidence.
