How 3D scans are measuring children's bodies

Today's generation of 11-year-olds are significantly taller and fatter than their parents were at the same age, a survey suggests.
According to the first ever nationwide sizing survey using 3D body scanners, both typical waistlines and height have increased over the last 30 years.
The survey, called Shape GB and carried out by Select Research, will use the results to better design children's clothes.
Girls are typically 2cm taller, with waist measurements up by 8cm, and boys are 4cm taller, with waists up by 7cm.
Before the full report came out, Richard Barnes from Select Research, showed BBC News examples of the scans.
