Marriage is one of the biggest decisions in life, and many people often wonder: “When is the right age to get married?” Interestingly, mathematicians and relationship experts have tried to answer this question using something known as the “37% Rule.”
This rule comes from a mathematical theory about decision-making, and it suggests that the “perfect” age to marry is between 26 and 32 years old.
Here’s how it works. According to the rule, if you start considering marriage from age 18, the best time to make a final decision is after you’ve observed and experienced about 37% of your “dating window.”
For most people, that falls in their late 20s. At this stage, you’ve had enough time to learn about yourself, understand what you want in a partner, and avoid rushing into youthful mistakes.
Yet, you’re still young enough to build a family and grow together with your spouse.
From a human point of view, this makes sense.
In your early 20s, many people are still discovering who they are—studying, working, or exploring life.
By the time you hit 26–32, you’ve likely gained emotional maturity, some financial stability, and clearer relationship expectations.
These are key ingredients for a successful marriage.
Of course, life is not just about formulas. Some people meet their lifelong partners at 21 and live happily, while others marry at 40 and still enjoy fulfilling marriages.
What this theory really reminds us is the importance of balance: don’t rush too early without understanding yourself, but also don’t delay so much that you miss the chance to build the kind of life you desire.
In the end, the “perfect” age to get married depends not only on numbers but also on readiness—emotionally, mentally, and financially. Love has no strict timeline, but making the decision at the right stage of life can increase your chances of happiness.
