What is the ideal title tag length?

Google displays approximately 580 pixels of title text on desktop (roughly 50-60 characters). Titles longer than this will be truncated with an ellipsis. Keep your most important keywords within this limit.

What is the ideal meta description length?

Google typically shows about 920 pixels of meta description text on desktop (roughly 150-160 characters) and about 680 pixels on mobile (roughly 120 characters). Aim for 150-155 characters for the best display.

Why does Google change my title in search results?

Google may rewrite your title tag if it determines another title better matches the search query. This often happens when titles are too long, stuffed with keywords, don't match page content, or use boilerplate text.

What is pixel width vs character count?

Character count is unreliable because characters have different widths (W is wider than i). Pixel width measures the actual visual width of your text, which is what Google uses to determine truncation. This tool measures pixel width for accuracy.

Preview how your result may look in Google before it goes live
