Korean Name Compatibility Test — Traditional Stroke Count Game
RandomThe Korean Name Compatibility Test is an entertainment-only tool that plays the traditional Korean stroke-count game: it interleaves two Hangul names, counts each character's strokes, and repeatedly keeps the last digit of neighboring sums until a two-digit score remains; it has no scientific basis.
What is it
The Korean Name Compatibility Test digitizes a game Korean students play in notebooks. Write the characters of two Hangul names alternately, count the pen strokes of each character, then repeatedly replace neighboring pairs with the last digit of their sum until only two digits remain — those two digits are the score. For example, 김철수 (7·11·4 strokes) and 이영희 (2·5·5 strokes) reduce as 7 2 11 5 4 5 → 9 3 6 9 9 → 2 9 5 8 → 1 4 3 → 5 7, giving 57%. Stroke-counting conventions are not standardized, so different sites can give different scores; this tool uses the stroke table shown below (each line segment counts as one stroke, compound jamo add their parts). The same input always produces the same score, and the game is entertainment only — names must be written in Hangul.
How to use
- 1Enter the first person's name in Hangul.
- 2Enter the second person's name in Hangul.
- 3Press the calculate button.
- 4Review the per-character stroke breakdown, the step-by-step addition pyramid, and the final score.

FAQ
Are the names I enter sent to a server?
No. The stroke counting runs entirely in your browser, and the names are never sent to or stored on a server.
Why do other sites show a different score for the same names?
Because Hangul stroke-counting conventions are not standardized (for example, ㅈ can be counted as 2 or 3 strokes). This tool follows the stroke table on this page, so the same input always returns the same score here.
Does the test work with non-Korean names?
No. The traditional game counts Hangul strokes, so both names must be written in Hangul syllables. Transliterate a non-Korean name into Hangul first (e.g. Alex → 알렉스).
Is there any scientific basis for name compatibility?
No. There is no causal link between name strokes and real relationships. It is a traditional entertainment game passed down between generations of students.
