A standard vinyl record cover for a 12-inch LP measures approximately 12.375 inches by 12.375 inches (31.43 cm by 31.43 cm). This size is typical for full- length albums and provides ample space for artwork and liner notes
. There are also smaller vinyl covers for other record sizes:
- 10-inch covers, often used for EPs, measure about 10.375 inches by 10.375 inches (26.35 cm by 26.35 cm)
- 7-inch covers, commonly for singles, measure roughly 7.125 inches by 7.125 inches (18.41 cm by 18.41 cm)
These dimensions allow the cover to comfortably house the vinyl record while offering a canvas for album art and information. Slight variations exist depending on manufacturer and style, but the 12.375-inch square is the widely accepted standard for 12-inch vinyl covers
