Lovehoney has found the size really does matter to some couples- when it comes to their height. The perfect height difference for couples is five inches according to research, as in Prince William and Duchess Catherine. 70% of people are more comfortable when the man is taller than they are.

19% said that 4-6 inches is the ideal difference, sported by a lot of our beloved celebrity couples. 

Daniel Craig and Rachel Weisz- 4 inches

Keira Knightley and James Righton- 2 inches


One in ten said that matching heights was more desirable- so good news for the celebrity couple Jason and Rosie! 

Jason Statham and Rosie Huntington Whiteley – Both 5ft 9 inches


Similar height was also preferable where there is only a 1 inch difference between the couple. 

Nicole Kidman and Keith Urban- 1 inch

A minority of 7% said the 6-8 inches was much better, such as in the couples photographed below: 

David Beckham and Victoria Beckham- 7 inches

Only 14% of women wanted their men to be taller- Jamie Cullum (5ft 4in) need not worry as he stands next to Sophie Dahl at 5ft 11 in!

A Lovehoney spokesman said: "The long and short of it that size DOES matter to a lot of couples. And the height of romance appears to be when the man is five inches taller than the woman - just like William and Kate. But all our research at Lovehoney shows that size isn't important when it comes to real sexual chemistry. That comes from couples from being honest, open and relaxed about sex."
