Vinyl record album covers are usually 12 inches by 12 inches for LP albums. For singles, covers of 7 inches are common because of the format's smaller size. Records in the 78 rpm format were usually sold with 10 inch covers but are uncommon today.
The size of a vinyl record determines how much music can be recorded on the record. Though 12-inch records once only contained around six minutes of recordings, technological advances allow the format to hold around 30 minutes of audio per side. A denser vinyl record allows for a higher quality of sound, and 180- to 220-gram vinyl is preferred by audio enthusiasts.
