How many copies of Metallica's Black Album had been sold worldwide according to its standard sales summary?

Metallica's Black Album had sold over 30 million copies worldwide according to its standard sales summary.

That figure made the self-titled 1991 record the band's best-selling album and one of the best-selling albums in music history. Its success was powered by sustained sales rather than a brief release-week spike, with the album remaining available in multiple physical formats and continuing to chart for decades.

The worldwide total should be distinguished from regional figures. In the United States, the album accumulated more than 20 million copies and received a 2× Diamond certification from the RIAA in 2025. Worldwide totals include sales from many countries and therefore are not interchangeable with the U.S. certification figure.

The album's longevity also helped its total grow across changing music formats. It began in the compact-disc, cassette, and vinyl era, then continued to sell through reissues and digital distribution. The 2021 remastered edition and deluxe box set renewed attention without changing the identity of the original 1991 album.
