Baseball Diamond vs. Ice Hockey Rink
Comparing 2 standards across 20 specifications. 20 key differences identified.
Official baseball diamonds are regulated by Major League Baseball (MLB Official Baseball Rules Rule 2.01). The infield is a 90 × 90 ft (27.43 × 27.43 m) square rotated 45 degrees. The pitcher's rubber is located exactly 60 ft 6 in (18.44 m) from the back tip of home plate on a mound raised 10 in (25.4 cm). Regulation outfield fences typically range from 325–350 ft at the foul poles to 400+ ft in center field.
Official ice hockey rinks are standardized by the NHL (200 × 85 ft / 60.96 × 25.91 m) and the IIHF (60.0 × 30.0 m / 196.85 × 98.43 ft). The playing surface is enclosed by 40–48 in dasher boards and tempered safety glass. Goal nets measure 6.0 ft (1.83 m) wide by 4.0 ft (1.22 m) high by 40 in deep, centered on goal lines 11.0 ft (3.35 m) from the end boards.
