You are implementing the UIImagePickerControllerDelegate Protocol and, in particular, the method imagePickerController:didFinishPickingMediaWithInfo:. The last parameter in this method is a dictionary, which includes UImage links using the key UIImagePickerControllerOriginalImage. Get this UIImage * and get its property size.

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {

    UIImage *image = (UIImage*) [info objectForKey:UIImagePickerControllerOriginalImage];
    //access width and height like this
    image.size.width;
    image.size.height;
}
