An advertiser wants to use a static image Pin and to make the most of the space in the feed without it being cut off when viewed. Which aspect ratio should the advertiser use?

The 2:3 aspect ratio (e.g., 1000 x 1500 pixels) is ideal for static image Pins because it provides a vertical orientation that maximizes visibility within the Pinterest feed without being cropped. Pinterest is designed for vertical content, and this ratio ensures your image takes up optimal screen real estate, capturing user attention effectively. A 1:1 aspect ratio (square) is too small and doesn't leverage the vertical feed space. A 9:16 aspect ratio is too tall and will likely be cut off, or require users to click to view the full image. A 16:9 aspect ratio is horizontal and will appear very small in the vertical feed, making it less impactful.
