Frequently Asked Questions

What is an ideal age difference?

There's no universally ideal age difference. Research suggests gaps of 1-3 years have slightly higher relationship satisfaction rates, but many successful relationships exist with larger gaps.

Does age gap matter for friendships?

Age gaps in friendships often matter less than in romantic relationships. Shared interests and life experiences often bridge generational differences.

How is sibling age gap calculated?

Sibling age gap is calculated the same way—by finding the difference between birth dates. Average sibling spacing is 2-4 years.
