MBTI Compatibility Chart

Each number in the MBTI compatibility chart is a letter count, computed directly from the two codes: energy letter (E or I), information letter (S or N), decision letter (T or F), and planning letter (J or P). INFP and ENFP, for example, share N, F, and P but differ on E/I — so their cell reads 3. ENFJ and ISTJ share only the F — their cell reads 1. The count is symmetric, so the MBTI compatibility chart mirrors across its diagonal: cell (A,B) always equals cell (B,A).

Start from a real relationship, not from the MBTI compatibility chart itself: pick your own code as one axis and a person you actually know as the other — a partner, a teammate, the friend you argue with about weekend plans. Open the four-axis panel and read the difference rows slowly; the value of the MBTI compatibility chart is not the number in the cell but the named, specific differences underneath it.

Then swap the pair and read the MBTI compatibility chart again — the prompts are written to be read from both seats. Copy the link to keep the exact pair, or reset to the default example. Two honest cautions: the chart describes self-reported letters, not the whole person, and real relationships respond to communication, history, and circumstance far more than to vocabulary overlap.

The discussion prompts under each pair exist because the useful version of type comparison is a conversation, not a verdict. "You plan, I improvise — how do we run a vacation?" is a question two people can answer; "we share two letters" is not. Teams use the MBTI compatibility chart the same way: reading the planning-axis row together turns "you’re being difficult" into "we sit on opposite ends of the closure preference", which is a much better starting point.

That is also why the chart links every published pair straight into the type guides: the letters are vocabulary, and the guides are the dictionary. Read your own guide, then the other person’s, then come back to the grid — the numbers mean more once the sentences behind them are familiar.

This MBTI compatibility chart is an independent, unofficial tool: original copy, deterministic comparison logic, free in your browser with no account. It is not affiliated with or endorsed by The Myers-Briggs Company or the Myers & Briggs Foundation, and "MBTI" appears here descriptively, for the well-known framework the sixteen codes come from.

Nothing about a pair you explore is stored or transmitted — the chart runs entirely client-side, and the shareable link contains only the two four-letter codes you chose, never any answers or personal data.

This site also has a pairwise comparison page built on the same engine as this MBTI compatibility chart. The difference is shape, not truth: that page is a two-selector form for when you already know the pair you want, while the MBTI compatibility chart is the whole 256-cell landscape for when you want to wander — spot the clusters, trace a row, notice how rare or common each count is. Both use the identical comparison logic underneath, so they can never disagree with each other.
