What is the recommended font size?

Because television screens must be read from across the room, use larger type sizes for body text (at least 14pt, which is approximately 19px on 720p and 28px on 1080p).

Keep item descriptions or other blocks of text as short as possible, both in content and in line width. Use greater line spacing than you would use on a desktop or tablet screen. Separate text into paragraphs or chunks and write in short, declarative sentences.
