The rule of 7 is a dating guideline that suggests you should date someone who is within 7 years of your own age. The idea is that a 7 year age gap provides enough common ground for a successful relationship, while still allowing both partners to be in similar life stages.
Where does the rule of 7 come from?
The origin of the rule of 7 is unclear, but it has been around as dating advice for many years. Some sources attribute it to French author Max O’Rell in his 1883 book Her Royal Highness Woman and Her Relationships to Man. The rule suggests that the ideal age gap between a man and woman is 7 years, with the man being the older partner.
The rationale was that a 7 year age difference provides an appropriate mix of similarity and difference. Partners close in age would have enough in common and be at comparable stages of life. But with a notable age gap, the man would have more finances and maturity to offer, while the woman would provide beauty and vibrance.
Does the rule of 7 work?
The rule of 7 is not an absolute requirement, but more of a general guideline that may work well for many couples. Research on age gaps in relationships has found that there are benefits to certain age differences.
For example, a study by Emory University found relationship satisfaction was highest when the woman was 8 years younger than the man. Other research has shown both men and women prefer an age gap with the man being older. However, excessively large age gaps may face greater social disapproval and challenges connecting at different life stages.
So while a 7 year age gap is not a must, it provides a reasonable starting point. Relationships with age gaps of 5-10 years tend to strike a balance, but ultimately it depends on the two individuals. Maturity, interests, life goals, and chemistry are more important factors than age alone.
Potential benefits of a 7 year age gap:
- Partners are close enough in age to relate, but have enough differences to maintain interest and attraction
- Similar pop culture references and childhood memories to bond over
- Close enough in life stage to have shared goals and priorities
- The man brings more financial stability and wisdom
- The woman offers youthful energy and a fresh perspective
Potential challenges of a 7 year age gap:
- There may be some judgment from family or friends
- If starting a family, fertility concerns may arise with a much older male partner
- The energy levels and interests of both partners may diverge over time
- Generation gaps in childhood experiences or technological proficiency
Does the rule of 7 change as you get older?
The appropriate age gap may shift as both partners get older. A 7 year age difference means something entirely different for a 20 year old than a 50 year old. As people mature and reach different life stages, their needs and goals evolve when choosing a partner.
In your 20s and 30s, a 7 year age gap often means both partners are in the same stage of establishing careers, settling down, and starting families. But after 50, interests and priorities may change as people focus more on retirement, grandparents, and getting fulfillment out of life.
So as people enter mid-life and beyond, a smaller age gap may become more appropriate. A 4-5 year age gap may provide the right mix of similarity and difference for older adults, rather than 7 years.
Does gender affect the rule of 7?
Traditionally, the rule of 7 suggests the man should be older, by 7 years. However, gender norms around age gaps have become less rigid over time. What ultimately matters is finding a partner who complements you.
For some couples, having the male 7 years older does work well. Maturity and resources from an older male partner may balance youth and vibrance from the younger woman. However, this is not the only formula for success.
In many couples, a younger male partner may appreciate the guidance of an older, more experienced woman. Or same-sex couples may have their own approach to age differences that suit their partnership.
The 7 year rule need not adhere to outdated gender roles. The priorities of each partner should determine what age gap feels comfortable, regardless of gender.
Does the rule of 7 apply across different cultures?
Attitudes around age gaps in relationships vary enormously across cultures. While the rule of 7 originated from Western culture, it does not necessarily apply globally.
Some traditional societies prefer larger age gaps, especially for first marriages. In areas like rural India, gaps of 10+ years are common and culturally encouraged. But other progressive cultures are less focused on age and more on personal connection. Parts of Latin America and Western Europe are more open to small age gaps close to the 7 year framework.
No single rule of age differences can fit all cultures. Local customs, family input, and personal choice drive what partnerships are embraced. The 7 year guide may have limited relevance in traditional societies, but does reflect emerging cultural norms around relationships with smaller age gaps.
Are there any alternatives to the rule of 7?
The rule of 7 should not be an absolute requirement, but does give a starting point to consider when evaluating age gaps. Some alternatives that provide similar guidance include:
Half your age plus seven
This rule states you should date someone no younger than half your own age, plus 7 years. For example a 30 year old could date someone as young as 22 (15 + 7). This rule allows for slightly wider gaps at younger ages, though suggests avoiding excessive differences in later years.
Ten percent age gap
Rather than 7 years, this rule looks at age gap proportional to your actual age. Ten percent of a 30 year old’s age is 3 years, so they could date someone 27-33. For a 50 year old, 10 percent is 5 years, allowing ages 45-55. The gap grows slightly wider along with age under this rule.
Five year range
A simpler guideline is keeping the age gap within 5 years in either direction, for any stage of life. While less nuanced than the rules above, this ensures partners are close in life experience and avoids drastic generation gaps between youth and middle age.
Key considerations for age gaps
Regardless of the exact age numbers, some key things to keep in mind when evaluating an age gap include:
- Life stage – Are you both in similar places in terms of education, career, maturity, priorities?
- Power dynamics – Does the age gap create issues with control or equality in the relationship?
- Social judgment – Will family members or society view the age gap as inappropriate?
- Interests – Do you connect on culture, hobbies, social activities you enjoy?
- Stability – If looking to settle down, does the age gap support your shared goals?
Conclusion
The rule of 7 provides a starting point for considering age gaps in dating. While not a hard requirement, a 7 year age difference can represent a sweet spot. Partners are close enough to connect meaningfully, yet maintain attractions based on differences. Ultimately what matters most is finding someone who complements you in terms of maturity, life stage, and goals for the future together.
