"Piece" counts the layers of a golf ball: a 2-piece has a core and a cover, a 3-piece adds one layer between them, and a 4-piece adds two. More layers mean more ways to tune spin and feel, but cover material matters as much as the count. For how hard a ball feels, see our golf ball compression chart.

“Piece” counts the separate layers: the core, any mantle layers and the cover. Layer names vary by maker, and sizes here are drawn for clarity, not to scale. Some makers, such as TaylorMade with the TP5, describe five layers.

The core is the engine of the ball. The cover is what the clubface touches. Layers in between, often called mantle or casing layers, let a maker control how the ball behaves with different clubs. TaylorMade says its five-layer TP5 design lets it "decouple" driver and iron speed from iron and wedge spin, according to launch coverage in Irish Golfer.

Urethane vs Surlyn covers

In the examples below, the higher-priced balls tend to use a urethane cover, and several of the 2-piece balls use a Surlyn (ionomer) cover. Examples from maker pages and named outlets:

The Vice Tour and Vice Pro show why the piece count alone misleads: both are 3-piece, but one has a Surlyn cover and the other cast urethane. Piece counts and covers can change between model years, so check the maker's current page before you buy.

Which should you choose?

  • 2-piece: a simple design that is often lower priced. A good fit if you want distance and value, or you lose balls often.
  • 3-piece: often paired with a urethane cover for more control around the greens, though not always (the Vice Tour above is a 3-piece with a Surlyn cover).
  • 4-piece or more: aimed at players who want to tune driver and short-game behavior separately, usually at a higher price (TaylorMade says its five-layer design is meant to do this).

None of this replaces trying a few balls. Our reviews cover several: the TaylorMade TP5, the Titleist AVX, the Vice Pro and the Srixon Q-Star Tour. We summarize published specifications and do not test balls ourselves. For the full list, see best golf balls.
