What was the approximate worldwide physical-media sales figure for Metallica's The Black Album?

Metallica's The Black Album sold approximately 31 million copies worldwide on physical media.

That figure helps explain why the 1991 album became the band's best-selling release and one of the most commercially successful heavy metal albums ever made. Its success was not limited to one market: the album debuted at number one in ten countries and received major certifications across several territories.

In the United States, the album also became the best-selling record of the Nielsen SoundScan era. It was the first album tracked by SoundScan to pass 16 million U.S. sales and later surpassed 20 million copies in the country. The RIAA awarded it 2× Diamond certification in 2025.

The worldwide total is often mixed up with U.S.-only figures or with shipment certifications. The approximately 31-million figure refers to physical-media sales worldwide, while domestic sales and certification totals describe different measurements.
