You should define these terms. They aren't obvious to everybody:

Logo: At least 256 x 256 px with a transparent background.

Email banners: Recommended 1100 x 220 px with a transparent background, but could be taller.

Cover image: At least 600 x 600 px.

Social / post preview image: We recommend at least 1456 x 1048 px, but 420 x 300 px is the minimum. 14:10 is the aspect ratio for the preview images.

And special thanks to Kellyn for her slides; so clean and minimal. Loved it.

What is recommended size for an image within a post? My home page shows the post's image as being too large to fit. Thanks.

What is the maximum file size for images (e.g art) included in the newsletter? I can't find this information anywhere.

Thanks for this article. It was very helpful and insightful. One question - is it a good practice to link previous substack articles in every new article ? Will it harm the readership ?

Is .png the best format to save images in, or is .jpg better? Also, I've noticed that the thumbnail images, the small images that show up on the "Archive" page, for example https://moviewise.substack.com/archive, seem to be pretty low resolution/fuzzy, even though when the article is viewed the main picture there is high resolution/sharp:

https://moviewise.substack.com/p/movie-wisdom-on-making-friends

Could someone help explain what may be wrong? Could the resolution in which the thumbnails are created be increased?

Thanks, folks! I've just hit 100 subscribers and am really excited to make the presentation better on the physical landing page. This gives me a lot to think about.

I appreciate all the style options available for defining identity and branding.

FYI - I just noticed this morning that at least one of the style choices I've made does not carry over to the iOS reader app. I chose the Sans typeface for both the body and content of my posts. Reading my own post in the iOS reader shows all text as Serif ... which I found difficult to read using my preferred dark more.

My subscribers are getting my posts with multiple dashes and hyphens added, that are not in the original I post. Anyone know why this is happening? Thanks, Ethan
