Scalable text
One UI text is scalable pixel and varies in size. All text except subtitles and text within images should be resizable up to 200% without affecting content or functionality.
Label toast
To help users understand icons without visible text labels, provide pop-up labels when users touch and hold the icons.
Font : size Level 3
Font : size Level 7
Large text layout
Keep in mind that as font size is increased, text can be cut off, making it difficult to understand. Provide enough space and stay within space limits.
