The font of the button text must be readable. Recommended font sizes for each image size are included in the PSD files.
The width of the right and left padding for the login button text must be equal to or greater than the width of the LINE icon speech bubble. This width is defined as X in the image below.
The recommended height of the top and bottom padding for the login button text is X/2. Make sure you use a font size that allows for this padding to be maintained.
The isolation zone is the space surrounding the LINE Login button which cannot contain any elements. The width of the isolation zone must be equal to or greater than the left padding of the LINE icon speech balloon. The width is defined as "A" in the image below. In addition to maintaining the isolation zone, avoid placing text or graphics near the isolation zone as that could compromise the effectiveness of the LINE Login button.
