The common misconception is that thin content is simply short content — in reality, a genuinely direct, complete answer can be entirely appropriate at 150 words (a glossary definition, for instance), while a padded, repetitive 2,000-word article that never actually says anything substantive is thin despite its length. Google's Helpful Content guidance specifically targets content created primarily to attract search traffic (checking boxes on a topic without genuine depth or usefulness) rather than content created primarily to serve a real audience's needs, which is the practical test worth applying: would this page exist, in this form, if search rankings weren't a consideration at all. Sites with a high proportion of thin content across many pages risk broader site-quality suppression, not just individual page underperformance, per the Content Pruning and Index Bloat entries.
Example
A 2,000-word article on 'what is a backlink' that repeats the same basic definition in five different paragraphs without adding new information is thin content, despite its length — while a direct, complete 200-word glossary definition covering the same concept isn't.
