What is a LINE Rich Menu?
A LINE Rich Menu is a persistent menu displayed at the bottom of a LINE Official Account chat. Users see it every time they open the chat — tapping a cell triggers an action such as opening a URL, sending a keyword, or claiming a coupon. For any industry, a rich menu is a fundamental part of running a LINE OA.
The rich menu is a valuable free advertising space: it does not consume broadcast message quota, making it a 24-hour always-on display with zero recurring cost.

5 Practical Tips for Rich Menu Design
1. Put the most important feature in the most visible spot
Users' eyes start at the top-left — place booking, shopping, or core features there for maximum clicks.
2. Lead with icons, support with short labels
Mobile screens are small. Clean icons with brief text labels are easiest to read. Avoid cramming in too much copy.
3. Match your brand colors and style
The rich menu is one of the first impressions users get — colors and style should align with your brand identity.
4. Ensure sufficient contrast between background and text
Light text on dark background, or dark text on light background. Avoid near-matching colors that are hard to read outdoors.
5. Preview on an actual phone
After designing on desktop, check the result on your phone — verify text clarity, button spacing, and overall feel.
