A human liver normally weighs approximately 1.5 kilograms (3.3 pounds) [11] and has a width of about 15 centimetres (6 inches). [12] There is considerable size variation between individuals, with the standard reference range for men being 970–1,860 grams (2.14–4.10 lb) [13] and for women 600–1,770 g (1.32–3.90 lb). [14]

The liver scratch test can be used when other exam techniques used to approximate liver size are ineffective or unavailable [2] and is thought to be most useful if the abdomen is distended, too tender for direct palpation, the abdominal muscles are too rigid, or the patient is obese.
