Google이 실제로 스니펫을 자르는 데 사용하는 지표인 문자 수와 픽셀 너비 모두로 제목 태그와 메타 설명을 검증합니다. SERP 미리 보기 포함.
Use the SEO meta length checker on every page before publishing. Both title and description should fit the SERP layout cleanly — too short wastes space, too long gets truncated with an ellipsis.
Character-only counters miss the truncation rule (Google uses pixel width). This tool combines both metrics so you can defend either to a stakeholder.
Google truncates titles and descriptions by pixel width, not character count. Arial-ish fonts mean E and i are narrow, M and W are wide.
This tool combines character count with a pixel-width estimate calibrated to Google's snippet font, and shows a SERP mockup so you can preview the truncation.
Mobile and desktop use different widths; toggle the device selector to see both.
Google rewrites titles based on the search query and what it thinks the user wants. Your tag is a strong suggestion, not a guarantee.
Pixels. Google truncates by visible width, so a description full of "iiiii" can fit more characters than one full of "WWWWW".
Mobile is narrower. Titles: ~520px mobile, ~580px desktop. Descriptions: ~860px mobile, ~960px desktop. Test both.

Title: "Free Online Readability Calculator — Redmoon" (47 chars / 458px)
출력
Title: good · Description: short (90 chars / 545px)
Google truncates by pixel width, not character count. 580px is roughly 60 characters in Arial. The status uses the device width to flag short / good / long.
