The heart is roughly the size of a

• A. Fist
• B. Foot
• C. Palm
• D. Coin

Answer: (A)

A basic way we gauge heart size is by comparing it to a clenched fist. In an average adult, the heart weighs about 250 to 350 grams and is roughly 12 cm long, 8–9 cm wide, and about 6 cm thick, which fits inside the chest in the shape of a fist. That makes the closed fist a good mental reference for the heart’s size. Among the options, a closed fist best matches the actual size. A foot is far larger, a palm is typically smaller than a clenched fist and would underestimate the heart, and a coin is much smaller than the heart.
