Why character counts mislead you

Google does not count characters. It renders your title and description into a fixed container and cuts whatever does not fit. A title of 60 capital W's is roughly twice as wide as 60 lowercase i's, so two titles of identical length can produce completely different snippets — one intact, one truncated mid-word.

The practical limits on desktop results are about 580 pixels for the title and about 990 pixels for the description, measured in Arial at 20px and 14px respectively. That works out to roughly 55–60 characters and 150–160 characters for average English text, which is where the familiar character-count rules of thumb come from. Those rules break down the moment your title is unusually wide or unusually narrow — brand names in caps, long compound words, or a lot of capital letters will hit the ceiling well before the character count suggests.

Mobile truncates differently, and usually earlier

Mobile results do not use a single pixel ceiling. The snippet sits in a narrow column and wraps, and Google clamps it after a set number of lines — commonly two for the title and three for the description. That means the thing that matters on mobile is not total width but where the line breaks fall. A long word near the limit can push a whole phrase onto a fourth line and lose it entirely.

Since most searches happen on mobile, check the mobile preview first and treat the desktop pixel meters as the secondary constraint. If a title fits in two mobile lines it will almost always fit on desktop too.

What the limit actually buys you

Staying under the limit is not the same as ranking better. Truncation is not a ranking factor; it is a click-through problem. A title cut mid-phrase loses whatever you put at the end, and the end is usually where the qualifier lives — the year, the location, the differentiator. Front-load the part you cannot afford to lose and treat the rest as expendable.

The bigger caveat is rewriting. Google replaces titles on a substantial share of queries and rewrites meta descriptions on the majority of them, usually pulling a passage from the page that matches the query more closely than your description did. So the description is a suggestion, not a specification. Write it to be the best possible answer for your primary query and accept that Google will often go and find its own.

How to use this

Paste the meta title and description you are about to ship. If a bar goes over, or the mobile preview clamps, you can see exactly what the searcher will be left with. Fix the ones where truncation destroys meaning, and leave the ones where it does not — a description cut after a complete clause still reads fine.
