Whether it's on Tinder or at a bar, how do you identify a potential long-term partner? Is it their height and frame? Their earning potential? Their smile?

A group of scientists at Chapman University in California have studied nearly 28,000 heterosexuals to decipher exactly what it is that men and women look for when finding a significant other.

Using the two largest studies of mate preferences ever conducted in America, they found that while some typical stereotypes such as "slender" bodies and earning power were true, other commonly held beliefs were challenged.

The biggest was that men and women care equally about having a partner who is specifically attractive to them.

Women put greater importance on resources, favouring a steady income (97%, compared to 74% of men), a successful career (61%, compared to 33% of men) and those who will or do make a lot of money (69%, compared to 47% of men).

Men on the other hand value attractiveness, and have a stronger preference for wanting a "slender" partner than women, with 80% of men indicating this as ideal in a partner. Only 50% of women asked selected "slender" as a quality they looked for.
