Babies born with big heads are likely to be more successful, a study has suggested. Research has linked the size of a child’s head with their academic achievements later on in life, finding that the bigger the head smarter a baby will be. 

Scientists investigating the link between genes, IQ and overall health made the discovery. 

Researchers collected blood, urine and saliva samples as well as background and lifestyle information for more than 100, 000 British people.From the data analysis the scientists discovered that people born with bigger heads were much more likely to get a college degree and score higher on a verbal/numerical test.

Babies born with a head circumference more than the average, which is 13.5 – 14 inches, seemed to have higher intelligence.“In addition to there being shared genetic influences between cognitive skills and some physical and mental health states, the study also found that cognitive skills share genetic influences with brain size, body shape and educational attainments," Professor Ian Deary of Edinburgh University, he told Neuroscience News.The study used data from 100,000 Britons, stored by the UK Biobank which has collected more than half a million samples from people aged between 37 and 73 years. 

The average newborn head size is 36cm for boys, and 35 cm for girls.
