Hi there! Usually, those image dimensions are part of the page here:
Twenty Twenty-Two
However, those specifications were left out of the page this time around. This is because the theme’s content width, featured image sizes, and site logo size are not set in stone. Users can change these values from within the new Site Editor:
Site Editor
That said — by default, if you do not make changes from within from the Site Editor, here are the values that the theme ships with:
– The main column width is up to 1000px wide. The “Wide” block width is also up to 1000px wide, and the “Full” block width extends the entire width of the screen.
– The recommended Featured Image size is 1000px wide or larger.
– The recommended size of the logo is at least 64px wide, or at least 64px tall.
I hope that’s helpful!
