The heart is approximately the size of a clenched fist and weighs between 10 and 12 ounces (280 to 340 grams) in adults. It measures approximately 5 inches (12 centimeters) in length, 3 inches (7 centimeters) in width, and 2 inches (5 centimeters) in thickness.

Location:

The heart is located in the mediastinum, which is the space in the chest between the lungs. It sits slightly to the left of the center of the chest, behind the sternum (breastbone). The base of the heart is at the top, pointing toward the right shoulder, while the apex (tip) of the heart is at the bottom, pointing toward the left hip.
