What is the size capacity of my DVD, Dual Layer DVD or Blu-ray disc?

DVD and Blu-ray manufacturers state capacity in decimal form. However, most computers read capacity in binary. The following table translates stated decimal capacity into actual binary capacity.

Note: In the table, GB means gigabyte and equals 10⁹ (or 1,000,000,000) bytes. Almost all computer software, including PTPublisher, will display binary gigabytes or gibibyte (GiB) which equal 2³⁰ (or 1,073,741,824) bytes.

*Actual capacity will vary depending on disc manufacturer. 

Example: Disc with 8.5 GB capacity will provide you: (8.5 x 1,000,000,000) / 1,073,741,824 ≈ 7.92 GiB or 7,920 MB.

**Primo DVD and PTPublisher display capacity in MB so all you need to know is that the max capacity for a DVD is 4,380 MB, for a DVD-DL is 7,920 MB, for a BD-R is 23,280 MB and for a BDR-DL is 46,566 MB.
