About this calculator
Overview
Hamming distance counts positions where two equal-length strings differ. Used in error detection, DNA analysis, and information theory. Only works with strings of equal length.
💡
Pro Tips
Strings must be equal length for valid calculation.
Binary: count bit positions that differ.
Text: count character positions that differ.
Distance of 1 means single error/substitution.
