While one mathematical theory dictates that 26-years-old is the ideal age at which to get married, new research suggests both men and women are ignoring this rule.
Wedding planning website Bridebook.co.uk has found that the average bride or groom in the UK is eight years older than those who got married in the 1970s. While the average age of a single woman getting married in 1971 was 22.6 years old, it is now 30.8 years old. For single men, the average age is 32.7, up from 24.6 four decades ago.
The brand's latest Marriage Report, which surveyed 4,000 recently married couples, also discovered that couples today have longer relationships before marrying - 4.9 years on average - and have generally had two previous serious relationships before they settle down with "the one".
With the cost of weddings at an all-time high, it's perhaps not surprising that many couples are allowing more time to save up for the big day. According to the research, feeling pressured into getting married isn't an issue either, with 92% of those asked saying there is less expectation to tie the knot today than there was for their parents' generation.
Hamish Shepherd, founder of Bridebook, says this can only be a positive thing.
"Weddings are now focused on the celebration of a couples' life-long commitment to one another, rather than the start of a new life together, and hence have become bigger and bigger occasions," he said in relation to the report.
"We have reached a tipping point where the divorce rate will likely be on the decline for the foreseeable future as marriage increasingly becomes the fully informed independent choice of couples wishing to demonstrate their commitment to one another without the pressure seen in previous generations."
What the study doesn't seem to take into account however, is the fact that same sex marriages have obviously been on the rise. Now that different forms of same sex partnerships have been legalised and recognised, it may impact the average age of marriage as people have more and more autonomy and an abundance of choice and options.
In other positive marriage news, a study of nearly a million adults found that having a supportive husband or wife inspires a desire to take better care of oneself.
