a body, comprising a heel portion, a sole portion defining a sole of the iron-type golf club head, a toe portion, a top-line portion, a front portion, which comprises a strike face, and a rear portion;
wherein:
a ratio of a maximum toe height of the iron-type golf club head to a blade length of the iron-type golf club head is greater than zero and at most 0.62;
wherein the maximum toe height is no more than 52 millimeters (mm);
a ratio of the maximum toe height to a maximum heel height of the iron-type golf club head is between, and inclusive of, 1.4 and 1.55;
the maximum heel height is no less than 25 mm;
a maximum thickness of the front portion, along the strike face, corresponds with a location toeward of a geometric center of the strike face;
