Stack Overflow question title character counter
Stack Overflow question titles have a 150-character maximum, and the editor also applies quality checks that reject vague or malformed titles. The title appears in search, duplicate suggestions, related questions, and tag pages, so spaces, code terms, punctuation, error names, and version numbers all need to fit clearly.
