A method comprising:

• receiving, by one or more processors coupled to memory, from a client device, a request for content, the request including one or more parameters corresponding to a content slot;
• identifying, by the one or more processors, a first display orientation of a content item selected responsive to the request for content;
• identifying, by the one or more processors, based on the one or more parameters of the request, a second display orientation of the content slot within which to display the content item;
• determining, by the one or more processors, that the first display orientation of the content item does not match the second display orientation of the content slot;
• and
• transmitting, by the one or more processors, responsive to determining that the first display orientation of the content item does not match the second display orientation of the content slot, the content item and instructions that when executed, cause the client device to adjust an aspect ratio of the content slot based on the first display orientation of the content item.
