These are real renders from the API with the example values in the table below. Switch the size above: the same template lays itself out for all 6 sizes — send size or sizes with the request.
For book clubs, reading apps, bookstores and newsletters recommending or reviewing a book. The stars fill to the rating out of five (halves too), the quote shrinks to fit and clamps, and without a cover the book is drawn with its title and author on the accent colour. Wide frames give the cover a column of its own; square frames set the title beside the cover and the quote across under both; vertical frames stack cover, title and quote.
