This is the business / brand cover for a LINE Official Account—not a VOOM timeline square and not the chat avatar.

LINE Official Accounts (OA) are how brands, shops, and creators run messaging, coupons, and rich menus in LINE-first markets. The cover is the wide strip visitors see on the account page—closer to a Facebook cover than to a VOOM post.
1100×600 is a practical community size for that banner. It is honest UI-based sizing—not a claim of a single official pixel forever. Preview the live OA page on phone and desktop after upload.
VOOM posts stay square (practical 1080×1080). Stretching a VOOM still into the OA cover letterboxes the art and wastes the strip. Chat avatars (640×640) are a third file.
WeChat Official Account headers use a different practical card (~900×500). Regional brands that run both messengers should keep separate masters instead of forcing one crop into both slots.
Same header strip—keep the avatar pocket clear and the subject in the open band.
Tick these off against your crop preview—nothing is saved.
Similar-looking slots often use different ratios—do not reuse one export for all of them.

The cover sets brand mood before someone taps Add friend, opens a rich menu, or reads an auto-reply. It should answer who you are in one glance—not dump a full campaign PDF into pixels.
VOOM is social sharing; the OA cover is the business storefront. WeChat Official Accounts use another header ratio. Cross-post brands should maintain LINE OA, LINE VOOM, and WeChat OA as three exports.
