A movie disc, typically referring to a DVD or Blu-ray disc, comes in two main sizes: 12 cm (4.7 inches) and 8 cm (3.1 inches) in diameter. Both sizes are 1.2 mm thick.
Here's a breakdown:
-
Standard Size (12 cm / 4.7 inches): This is the most common size for movie discs. It's the same size as a standard CD.
-
Mini Size (8 cm / 3.1 inches): These smaller discs are less common for movies but are sometimes used for special editions or promotional materials.
The diameter refers to the distance across the disc through its center. The thickness of 1.2 mm applies to both the standard and mini disc sizes. Both DVD and Blu-ray discs adhere to these dimensional specifications. A DVD can be single-sided or double-sided, affecting storage capacity but not physical size.
