What does 180 gram mean for a record?

It is the weight of the vinyl disc. A 180-gram pressing is thicker and stiffer than a standard one, so it is less prone to warping and holds its shape through repeated play.

Does 180-gram vinyl sound better?

Not automatically. Sound depends mostly on the mastering and the pressing plant. The heavier disc mainly adds durability and steadier tracking.

Will it play on my turntable?

Yes, if your turntable plays standard 12-inch LPs at 33⅓ or 45 rpm. Check the label for the speed, since the format alone does not tell you.

Is it a single LP or a set?

The listing describes one 180-gram record. Confirm the track count and disc count on the sleeve before buying if you expect a multi-disc set.

Should I pick this over a standard pressing?

If you play records often and want a disc that stays flat, the heavier pressing is the safer choice. If you mainly care about sound, compare the mastering credits instead.
