The 12" vinyl format is often referred to as an LP ("Long Play") as it can play much longer than the "Single" or "Extended Play" 7". LPs were 10" records at first, but soon the 12" size became by far the most common. While the 12" format is most commonly used for LP purposes, it is also quite common to see Singles and EPs pressed on 12" vinyl.

The recording time available on 12" records depends very much on the frequency spectrum, the dynamic range, the width of the stereophonic signal and other characteristics of the recording. While we recommend keeping 12" records playing times to 13.5 – 14.5 minutes at 45 RPM and 19.0 – 20.0 minutes at 33 1/3 RPM, Pirates Press can often accommodate records with playing times of 14.0 – 15.5 minutes at 45 RPM and 20.0 – 22.5 minutes at 33 1/3 RPM.

The 12" format is available on Standard weight (140 ± 10 g) or Heavy weight (180 ± 10 – 220 ± 10 g) vinyl. The 12" Center Hole is available as "Small Hole" only.
