VOOM is LINE’s social feed—square posts, not OA banners

LINE is the dominant messenger across Japan, Taiwan, Thailand, and more. VOOM is the in-app social timeline—closer to a Moments / Instagram-style feed than to a business Official Account page. Square 1080×1080 is a practical community size for VOOM stills.

Friends and followers judge your post as a compact card in chat-adjacent chrome. Landscape blog heroes and ultra-wide OA banners look stretched or letterboxed. Design a true square with one clear subject.

Official Account covers (practical ~1100×600) are a brand strip for business profiles—not VOOM posts. Chat profile pictures are smaller circles (practical 640×640). Export each surface separately.

WeChat Moments and Instagram squares can be starter files, but LINE’s UI and cultural cues differ. Re-crop and preview inside LINE—especially for Japanese and SEA audiences who read VOOM daily.

Good vs weak crop

Same feed frame—keep the subject inside the margin phones actually show.

Clear square VOOM card

  • True 1080×1080
  • Subject fills the card
  • Short readable CTA if needed

Wrong surface stretch

  • OA banner stretched to square
  • Soft phone dump with empty rims
  • Micro text on the edges

Before you upload

Tick these off against your crop preview—nothing is saved.

VOOM posts vs Official Account covers

VOOM is social sharing among contacts and followers. Official Accounts are brand channels with a wide cover strip, rich menus, and messaging automation.

Never upload an OA cover into VOOM and hope—the ratios fight each other. Keep a square master for VOOM and a dedicated ~11:6 cover for the OA page.

Design for the VOOM timeline card

Most people skim VOOM between chats. One product, face, or scene beats a dense flyer. Keep captions in the text field when possible; on-image words should stay large.

  • Prefer one subject in the safe center.
  • Match brand mood to your OA without copying the banner crop.
  • Test on a phone before a campaign push.

File requirements

JPG for photos; PNG for hard graphics. Prefer sRGB. Keep files light for mobile VOOM uploads.

Common mistakes

  • Stretching the Official Account cover into a VOOM square.
  • Using a chat avatar as the full post image.
  • Landscape letterboxing that wastes the card.
  • Tiny promotional text that fails on phones.

How to use the crop tool

Upload, choose VOOM post (1080×1080), keep the subject in the zone, then download. Cropping stays in the browser.

  • Zoom until the subject fills most of the square.
  • Prefer fewer words on the image.
  • Publish in LINE VOOM yourself.
