With a combined height of more than 13ft, Wilco Van Kleef-Bolton and his wife Keisha are the world's tallest married couple.
If their two children keep growing they may end up with the world's tallest family title too. Son Lucas, four, is already 3ft 11in - the height of a seven-year-old - and daughter Eva, two, is 3ft, the typical height of a three-year-old.
Dutch-born Wilco has to go to specialist websites that normally supply American basketball players to order the size 15 shoes he wears, whilst Keisha says her biggest problem was finding clothes large enough for her and her 38 in legs, even though she is a healthy size 12.
The Guinness World Record holders met when Wilco responded to Keisha's advert for a dance partner on a website for tall people, saying: 'I'm 7ft. Is that tall enough?'
Keisha, who had to wear men's clothing when she was pregnant because there weren't any maternity outfits big enough, said she and her husband would like to have more children.
'We think four is the ideal number but we think we can wait until these two are a bit bigger. Looking at them, it won't take that long,' she added.
