Schema Article AMP 1:1, 4:3, and 16:9 images for Google

The latest release of WPSSO Core v6.3.0 and the WPSSO JSON v2.9.0 add-on include new image sizes in Schema Article AMP markup for Google.

A few months ago, Google quietly updated their AMP structured data guidelines to suggest that:

For best results, provide multiple high-resolution images with the following aspect ratios: 16×9, 4×3, and 1×1.

Since WPSSO Core and its add-ons already use a variety of image sizes for different markup standards (ie. Open Graph, Twitter Cards, Schema, etc.), it was fairly easy to add support for Google’s new Article AMP image sizes. You can find the new images sizes, along with all other WPSSO image sizes, under the WordPress Settings > SSO Image Sizes settings page.

The default (and recommended) image sizes are:

Open Graph (Facebook and Others)1200x630px cropped.
Schema (Google and Pinterest) 1200x1800px uncropped.
Schema Article (Google and Pinterest) 1200x1800px uncropped.
Schema Article AMP 1:1 (Google) 1200x1200px cropped.
Schema Article AMP 4:3 (Google) 1200x900px cropped.
Schema Article AMP 16:9 (Google) 1200x675px cropped.
Schema Thumbnail Image 1200x630px cropped.
Twitter Summary Card 1200x630px cropped.
Twitter Large Image Summary Card1200x1800px uncropped.

Note that several of the image sizes share common dimensions and crop settings — this allows WordPress to create fewer image files on disk (ie. only 5 image files for all 9 image sizes).
