Why character limits are mostly lies
Almost every "limit" quoted for search results is a character count standing in for a pixel budget. Google renders desktop titles in Arial at 20px and cuts them at roughly 600 pixels. The word "Illinois" and the word "Wowwww" have the same character count and nowhere near the same width, so a 60-character title fits comfortably or gets truncated depending entirely on which letters you used.
Real character limits do exist, and they are the ones enforced by software: X cuts at 280, a CMS field rejects input past its column width, an Open Graph title gets clipped by the platform rendering the card. Those are worth counting exactly.
Which to trust
- Platform limits are hard. Count characters, respect the number.
- Search limits are soft. Measure pixels with the SERP preview instead.
