1. A golf club head comprising:
a crown;
a sole; and
a club face, attached to the crown and the sole, having a maximum height and a maximum width and including a central region, a toe region, and a heel region, wherein:
the central region includes first laser-generated features;
the toe region includes second laser-generated features;
the heel region includes third laser-generated features;
the third laser-generated features, in the heel region, nearest the sole are spaced a first distance, measured in a heel-to-toe direction, apart from the second laser-generated features nearest the sole in the toe region;
the third laser-generated features, in the heel region, nearest the crown are spaced a second distance, measured in the heel-to-toe direction, apart from the second laser-generated features nearest the crown in the toe region, the second distance being greater than the first distance;
a width-intersection coverage of the central region provided by the first laser-generated features is at least 90%;
a height-intersection coverage of the central region provided by the first laser-generated features is at least 90%;
a width-intersection coverage of the toe region provided by the second laser-generated features is at least 90%;
a width-intersection coverage over the heel region provided by the third laser-generated features is at least 90%;
the height-intersection coverage of the central region provided by the first laser-generated features is greater than a height-intersection coverage of the toe region provided by the second laser-generated features and a height-intersection coverage of the heel region provided by the third laser-generated features;
the height-intersection coverages are measured using a height increment of 0.1 mm.
