What Is a LINE Rich Menu?
A LINE Rich Menu is a fixed menu displayed at the bottom of a LINE Official Account (LINE OA) chat window. It's always visible when users open the chat. Tapping a section triggers an action — opening a URL, sending a keyword, redeeming a coupon, and more. From beauty studios and nail salons to restaurants, clinics, and e-commerce brands, a rich menu is a fundamental part of running a LINE Official Account.
Rich menus are a valuable free advertising space: they don't count toward broadcast message quotas — effectively a 24/7 free display slot. Compared to broadcast messages that consume your message quota, optimizing your rich menu is one of the most cost-effective LINE marketing moves you can make.

5 Practical Rich Menu Design Tips
1. Put the Most Important Function Where Eyes Land First
Users naturally scan from the top-left. Place core functions — booking, shopping — in the left or top sections for the highest tap rate.
2. Icons First, Text Second
Mobile screens have limited space. Simple icons with short text labels are easiest to read. Use free icon resources like Flaticon or Icons8 — avoid cramming in too much text.
3. Match Your Brand Colors and Style
The rich menu is one of the first brand impressions users see. Colors and style should be consistent with your brand identity to build a professional image.
4. Ensure Strong Contrast Between Background and Text
When choosing background images, pair light text with dark backgrounds, or dark text with light backgrounds. Avoid colors that are too similar — text can become illegible outdoors or on low-brightness screens.
5. Always Preview on Your Phone
After designing on a computer, check on your actual phone. Is the text legible? Are the tap areas large enough? Does the overall visual feel comfortable?
