12-Inch Vinyl Record Sleeve Size: Exact Dimensions

What size is a 12-inch vinyl record sleeve?

A standard sleeve for a 12-inch vinyl record is typically about 12.375 inches by 12.375 inches (roughly 31.4 cm x 31.4 cm) on the outside. That extra fraction over 12 inches gives enough room for the record jacket (and any inner sleeve) to slide in and out without snagging, while still staying snug enough to protect corners and edges.

It helps to separate a few similar-sounding measurements:

The record size: A “12-inch” record refers to the disc diameter (about 12 inches across).
The jacket size: Most LP jackets are just over 12 inches square, often around 12.25 inches square, though it varies by manufacturer.
The outer sleeve size: Most protective outer sleeves are slightly larger, commonly 12.375 inches square.

If you’re buying protective sleeves, the right choice depends on what you’re covering. A single LP in a standard jacket usually fits a “standard” 12-inch outer sleeve. Double albums, gatefold jackets, or thick “tip-on” jackets may need an oversized or resealable sleeve with more width (often marketed as 3-mil to 5-mil options with a roomier fit).

For storage, it’s also smart to consider shelf clearance. Since many sleeves and jackets land in the 12.3–12.4 inch range, a record cubby that’s truly tight at 12 inches can scuff edges over time. Aim for a little breathing room so jackets slide out cleanly.

If you’re dialing in a full listening setup—turntable, speakers, and accessories—outer sleeves are one of those small upgrades that keep your collection looking new.

FAQ

What’s the difference between an inner sleeve and an outer sleeve for vinyl?

An inner sleeve holds the record itself inside the jacket, while an outer sleeve covers the entire jacket to protect it from shelf wear, scuffs, and dust. Many collectors use both for better long-term protection.
