How big is Ice hockey puck?
For this comparison, Ice hockey puck measures 7.62 cm in diameter (3 in). Regulation 3-inch diameter; thickness is not being measured.
A puck is not a sphere: diameter and thickness describe different dimensions.
Put the measurement in perspective
The recorded diameter is 0.045 times the height of A 1.70 m person (1.7 m). This is a ratio of the labelled linear dimensions. It does not describe weight, area or volume.
Use the interactive comparison to see both drawings on one shared scale. You can choose another reference or enter your own height. If the sizes are very far apart, the smaller object may be almost invisible; an intermediate reference makes the progression easier to inspect.

The note above explains the specific value selected. Drawings are schematic; the stated measurement determines the scale. Report a measurement issue.
Check the convention
Some equipment is governed by an allowed range rather than one exact size. Defined everyday references and any derived diameters are explicitly labelled in the note.
