Dear ClaPat Studio

I'm just beginning to set up the Berger WordPress theme.

I've been looking through the forum trying to find the optimal sizes for images that will be used in Berger.

I have found various sizes by not definitive sizes for the various uses. Images sizes like:

1920 x 700 px @ 72, 1200 x 640 px @ 72, 1500 x 800 px @ 72 or 2000 x 1067 @ 72

Please advised on the definitive optimal sizes of images for Berger.

I just need the optimal image sizes, I don't need information on the optimization of images or the link to the Google website for image optimization (https://developers.google.com/web/fundamentals/performance/optimizing-content-efficiency/image-optimization?hl=en) I'm covered there. I generally try to keep main images under 200 kb and gallery images under 100 kb.

Thank you for your help.
