I’ve figured this out. Appears as though I really wanted add_image_size(‘post’, 475, 475, true); and then reran the Regenerate Thumbnails plugin.

the_post_thumbnail() only retrieves the specified thumbnail size for the current post. You’ll need to write a conditional function or use a custom query to randomize the posts shown or thumbnail sizes from your theme’s loop. If you are familiar with where your loop starts, then: $tile_sizes = array(‘small’,’medium’,’category-thumb’); LOOP STARTS $random_size = rand(0,2); $chosen_size = … Read more
