Every character limit that actually matters in 2026
Tweets, titles, meta descriptions, text messages, resumes — the real numbers, why they exist, and which ones you can safely ignore.

Half of writing for the internet is fitting into boxes someone else sized. Here are the limits worth memorizing, and the ones that are folklore.
Google search results: titles get roughly 50-60 characters before they’re cut off, meta descriptions around 155-160. These aren’t official limits — Google measures pixels, not characters — but stay under them and you won’t get the mid-sentence ellipsis that makes results look sloppy.
Social and messaging
X/Twitter allows 280 characters for regular accounts, though engagement data has long favored posts far shorter than the ceiling. LinkedIn posts truncate around 210 characters before the ‘see more’ fold — those first 210 are the whole game. Instagram captions cut at 125 characters in feed view. SMS is still technically 160 characters per segment; modern phones stitch segments invisibly, but bulk-messaging services still bill by them.
The folklore limits
‘Blog posts must be 300+ words for SEO’ — no such rule exists; Google has said repeatedly that word count is not a ranking factor. ‘Resumes must fit one page’ — recruiters themselves report two pages is fine past your first job or two. ‘Email subject lines must be under 50 characters’ — testing shows subject length barely moves open rates; what the first three words say matters more.
The practical takeaway
Write first, measure after, cut to fit. The counter above shows characters live, so paste your draft title or description and trim until it clears the bar. The limits that punish you (search snippets, ad headlines, SMS billing) deserve respect. The folklore ones deserve a shrug.
