You implement the UIImagePickerControllerDelegate Protocol and in particular the imagePickerController:didFinishPickingMediaWithInfo: method. The last parameter in that method is a dictionary that includes an UImage references by the UIImagePickerControllerOriginalImage key. Get this UIImage* and get it's size property.

- (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;
}
