What is the Saju 16-Type Compatibility Chart?
The Saju 16-Type Compatibility Chart crosses two Saju 16 Types — each drawn from a birth date — along the top and side to lay out the chemistry of all 256 (16×16) combinations on a single page. The number in each cell is a chemistry score from 0 to 100 for how well the two types fit together, and the darker the color, the stronger the match. Tap a cell to see why that score came out and how the two types meet. For a deeper reading tailored to your relationship — a crush, a partner, a friend, an acquaintance — see 16-Type Compatibility.
Each type is estimated by mapping the Five Elements, Ten Gods, and Yin-Yang of your Saju onto four axes. The letters may look like MBTI, but the starting point is your Saju, not a personality quiz. To find your own type first, try the Saju 16 Types test.
How to read the chart
- Find your type along the top row and the other person's type down the side.
- The number in the cell where the two lines meet is the chemistry score.
- The darker the color, the better the match — check the legend above for what each score band means.
- Tap a cell to see why that score came out and a breakdown of each type.
The chart is symmetrical, so 'your type × theirs' and 'theirs × your type' give the same score.
How the chemistry score is decided
The four axes split into ones that work best when they match and ones that work best when they differ.
- Energy · Outward (E) · Inward (I) — different is +. One steps forward while the other looks after things, and the two balance out.
- Perception · Hands-on (S) · Pattern-seeking (N) — same is +. You see the world through the same lens, so conversation flows.
- Judgment · Analytical (T) · Empathetic (F) — same is +. You weigh decisions in a similar way, so there's less friction.
- Approach · Structured (J) · Adaptive (P) — different is +. Drive and flexibility fill in for each other.

Does a low score mean you don't fit?
No. A low-scoring combination isn't 'clashing' — it simply means the two of you differ in bigger ways. Once you accept each other's approach, it can turn into the relationship you learn the most from. That's why the bands say The pull of opposites · Worth the effort instead of 'clashing.' Every result is for entertainment and self-reflection.

Frequently asked questions
It's a Saju compatibility chart — so why do the letters look like MBTI?
We map the Five Elements, Ten Gods, and Yin-Yang of your Saju onto four trait axes (Energy, Perception, Judgment, Approach), expressing each one in plain words — Outward/Inward, Hands-on/Pattern-seeking, Analytical/Empathetic, Structured/Adaptive. We add the familiar MBTI letters (E/I and so on) only for reference; this isn't a formal personality test (MBTI®) but a Saju-based estimate from your birth date.
If the score is high, does that guarantee a good match?
The score is a tendency that combines how the four axes complement or align with each other, plus the 'golden pair' bonus. A real relationship depends far more on effort and circumstances, so take it as something for fun, not a fixed verdict.
Does a low score mean you don't get along?
No. A low score doesn't mean 'clashing' — it means the two of you differ in a lot of ways. Once you accept those differences, it can become the relationship you learn the most from. That's why the bands say 'The pull of opposites' and 'Worth the effort.'
Can I check compatibility even if I don't know my friend's type?
Yes. Check your own type first, then tap 'Check compatibility with a friend' to send an invite link. Once your friend enters just their birth date, their type is found automatically and your chemistry shows up right away.
Which combination fits best?
The highest scores go to combinations that read the world and weigh decisions in similar ways while complementing each other in energy direction and in how they get things done — for example, The Meadow Lark × The Lamplight Keeper. The eight 'golden pairs' whose thinking styles interlock like mirror images (The Meadow Lark × The Midnight Strategist and the like) also tend to score high. The score is only a tendency, so compare them yourself in the chart above.
