ACA Banner Advertising

The following are the standard banner ad sizes for sponsor and affiliate ads on the ACA website.

• Long Horizontal (728×90 pixels)
• Medium Rectangle (300×250 pixels)
• Large Skyscraper (300×600 pixels)
• Square (250×250 pixels)

We implement the ads in a responsive format, meaning that they will resize and adjust for different screen sizes.  For example, the Long Horizontal (728×90) on mobile will actually show up smaller at around 400 pixels in width and about 50 pixels tall, whereas the Medium Rectangle (300×250) will show up larger at around 400 pixels wide and 330 pixels tall.  We consider the Long Horizontal ad size great for inline content and the other 3 ad sizes for sidebar use.

For ad file size limits, all ads must be 72dpi (web standard) and no larger than 150Kb in JPG, GIF, or PNG formats only.

ACA Guide and Affiliate listings with inline logos are allowed up to 1Mb images to be uploaded in JPG, GIF, PNG, or BMP formats only.  Uploaded images will be automatically cropped and resized to a 450x450 square on display.
