Vinyl records with longer programs (over 19-20 minutes per side on a 12-inch LP) require grooves to be shallower and closer together due to the fixed physical diameter, which reduces maximum volume and further lowers dynamic range compared to shorter-sided records.

“If you have over 19-20 minutes of music on one side, the mastering engineer is going to have to start making adjustments in how they cut the lacquers, because a longer program on the same 12-inch diameter means the record needs to accommodate more grooves.”
