How the similarity score works
Each score is calculated by comparing 62 letters and digits (A-Z a-z 0-9) rendered at a 160px cap height on a 32×32 grid with 3px gaussian blur, combined with edge-orientation texture (weighted at 15%).
Scores are normalized on a standardized scale: 100 represents identical letterforms, and 0 represents an average pair among the 1571 fonts compared.
