Fun Insights
Little facts like what percentage the gap represents, or if they share the same birthday (rare but awesome!).
How Common Is Your Age Gap?
Most couples fall within a few years of each other, but there’s no “right” number. Here’s what the data shows:
| Age Difference | How Many Couples | What It’s Like |
|---|---|---|
| 0-1 years | 25% | Super close in age, same generation vibe |
| 2-3 years | 32% | Most common—the sweet spot for many |
| 4-5 years | 20% | Noticeable but totally normal |
| 6-10 years | 15% | Bigger gap, different life experiences |
| 11-15 years | 5% | Significant difference, less common |
| 16-20 years | 2% | Large gap, generational divide |
| 20+ years | 1% | Major difference, rare but happens |
Bottom line? If you’re happy, the number doesn’t matter. But it’s interesting to see where you fall.
