Legal Age Difference for Marriage by Country | AgeGapCalc
Minimum marriage ages are set by each country’s law, often 18 with exceptions for parental consent or judicial approval.
Our calculator shows the exact age gap between two partners, useful when reviewing these rules.
The Common Baseline
Most jurisdictions set a minimum age of 18 for marriage without consent, with some allowing 16 or 17 with parental or judicial approval. The limit applies to each person individually, not to the gap between them.
Why a Calculator Helps
Where age rules exist they are written in years and checked on a specific date, so the exact ages of both people on that day are what matter.
Confirm Locally
Rules differ widely and change over time, and consular requirements can add further conditions. Treat any general figure as a starting point and verify it with an official source.
What the Law Usually Regulates
Marriage law normally regulates the minimum age of each party rather than the difference between them. Where a gap does appear in a rule, it is usually about the age of the younger person at the time of the marriage.
Because eligibility is assessed on a date, calculating both ages on that exact day is the reliable way to check a case.
Common Misunderstandings
A frequent misunderstanding is that the law caps the difference in age between two people. In most places it regulates the minimum age of each person instead.
The second is assuming one age applies worldwide. Rules differ by country, change over time, and often carry exceptions that depend on consent or court approval.
