What dimensions are specified for a half page banner ad?

The correct dimensions for a half page banner ad are 300x600 pixels. This size is often recognized as a large ad unit that provides significant visibility and allows advertisers to present more detailed content compared to smaller ad formats.

The option provided as the answer, 300x60, represents a mobile leaderboard ad, which is not classified as a half page banner. Other dimensions listed include 300x250, which is a medium rectangle, 728x90, which refers to a leaderboard ad, and 970x90, which is a larger version of the leaderboard ad. None of these options match the industry standard for a half page banner ad, which emphasizes the importance of knowing the correct specifications for effective digital advertising placements.
