Complete Creation Guidelines

Required Images and Creation Tips

Themes sold through LINE must be updated to support LINE's latest features.
Themes that have not yet been updated can continue to be sold with LINE's default images or existing images used instead.
Please see the updated guidelines and create the required images.
Note: These guidelines are updated every time specifications related to themes are announced with a new version of LINE.

Chat Background Image 2 i_22.png 1482 x 1334 a_22.png 1300 x 1300
Tips

You can optionally create a chat background image. If you don't create one, the background design of the selected color skin or background color will be used instead.

iOS
Max: 1482 x 1334
Min: 60 x 60
Te display size for images in portrait mode is 640 x 1334.

Android
Max: W1300 × H1300
Min: W60 × H60

Graphics must always be centered and bottom-aligned regardless of device orientation.
Graphics will be aligned above the chat bar on iOS devices.
On Android devices, the graphics will be aligned beneath the chat bar. The chat bar may obscure the bottom portion of your graphic, so allow a suitably large margin at the bottom to prevent this.
Note: The theme preview provided after uploading your theme may differ from the actual device display.

As long as a graphic's size is within the specified minimum and maximum limits, any size is acceptable. Images can be either transparent or opaque. If an image's background is transparent, the graphic will be shown layered over the background design of the selected color skin. Files must not exceed 1 MB.

Chat Screen Background Color

If you use a chat screen background image, it may not fill all devices' screens. Any excess space is filled in with your theme's color skin by default. Use one of the following methods to prevent any jarring breaks.

• Select a background color that matches your chat screen's background color.
• Create a chat screen background image that matches your color skin.
• Keep your chat screen background image transparent to blend it with either your selected background color or color skin.
