MBTI Compatibility Calculator
Pick two of the 16 MBTI types and see the compatibility signal instantly — cognitive fit, conflict style, and where you grow each other.
How the calculator works
Cognitive function fit
Types whose dominant functions interlock (e.g. INFJ's Ni with ENFP's Ne) score highest. The classic 'golden pair' dynamic.
Shared dimensions
Each shared letter (I/E, S/N, T/F, J/P) adds to ease of everyday alignment — similar rhythms, less translation overhead.
Growth edges
Dimensions you don't share are where friction lives — but also where you grow each other most. Most long-term pairs thrive here.
Want your own four-letter type first?
The calculator is more useful when you're sure. Take the free 5-minute test to confirm your type, then use it here for real compatibility readings.
