I wasted my first Substack banner. I threw something together in Canva in about 10 minutes, used the wrong dimensions, and did not think about what it was supposed to communicate. It looked fine at full size on my desktop and blurry on every other device. A few months in I redid it from scratch with actual intention, and I noticed an immediate difference in how people responded to my newsletter page. That probably should have been obvious from the start.
If you want the complete Substack setup from account creation through launch through paid growth, I wrote the whole thing in my ebook Substack 101: A No-Fluff Guide to Building and Growing a Paid Newsletter, available at ballenpublishing.com for $27. Here is the banner and profile setup piece specifically.
Substack Banner Dimensions and Format
Substack recommends a banner image of 1100 x 220 pixels. That ratio is very wide and very short, which means most design instincts about visual composition do not transfer cleanly from other formats. You have a narrow horizontal strip to work with. Text needs to be large enough to read at that height. Complex imagery gets compressed and loses clarity. Simple and bold works far better than detailed and intricate.
I design my banner in Canva using a custom canvas set to exactly 1100 x 220 pixels and export as a PNG at the highest quality setting. JPEG compression at that size creates visible artifacts, especially around text edges. PNG keeps everything sharp.
What My Banner Actually Contains
My banner has three elements: my newsletter name in large readable type, a one-line description of who the newsletter is for, and a background that reflects my content’s tone without competing with the text for attention. That is it. Three elements, intentionally chosen, nothing extra.
The newsletter name needs to be the dominant visual element. Someone scrolling past your Substack on the platform or seeing it linked somewhere should be able to read your name without squinting. Large type, high contrast against the background, no decorative fonts that sacrifice readability for style.
The one-line description is the second-most important text element on the banner. It tells a visitor immediately what the newsletter is about and who it is for. Mine is written in plain language that matches how my ideal reader would describe their own situation. Clever copy that requires interpretation slows down the decision to subscribe. Clear copy that resonates immediately speeds it up.
The Profile Picture
Substack is a platform built around individual writers. Readers are following a person, and a person has a face. My profile picture is a clear headshot with good lighting, a clean background, and an expression that reads as approachable rather than formal. It is not a logo, not a lifestyle shot, not a blurry candid from three years ago that I kept because I like how my hair looks.
The profile picture appears everywhere on Substack: next to your newsletter name in search, next to your Notes in the feed, in emails your subscribers receive. Every one of those placements is a recognition moment. A consistent, high-quality headshot builds familiarity over time. Familiarity leads to trust, and trust leads to paid subscriptions.
The Cover Photo for Individual Posts
Each Substack post can have its own cover photo that appears at the top of the article and in email previews. I use a consistent template for these as well. The cover photo is 1200 x 630 pixels and includes the article title in large readable type over a simple visual background that reflects the newsletter’s overall aesthetic.
The consistency matters. When a new reader finds one of my posts through a recommendation or a search result, the cover photo tells them before they read a word that this comes from a newsletter with a consistent visual identity. That implicit signal of professionalism reduces the hesitation before subscribing. I built the cover photo template once in Canva, saved it, and now spend about two minutes per post updating the title text before exporting. The rest of the template never changes.
The About Page: The Section Most Writers Underinvest In
The About section of a Substack newsletter is the highest-converting page on the platform for turning visitors into subscribers and free subscribers into paid ones. Most writers fill it in with a brief paragraph and move on. I treated mine as a sales page.
My About page explains what the newsletter covers, who it is written for, what the publishing cadence is, what is included in the free tier, what is behind the paywall, and why I am the right person to be writing about these topics. It answers every question a potential subscriber might have before they have to ask it. A well-written About page removes friction from the subscribe decision. A vague About page creates it.
Setup Is the Beginning, Not the Point
Getting the banner, profile, and cover photos right is the foundation. What the foundation has to support is the actual newsletter: consistent publishing, a clear paywall strategy, a growth system that uses Notes and recommendations and Substack Live to reach new readers, and a pricing structure that converts free subscribers into paid ones over time. The visual setup earns the first look. The system earns everything after.
I walked through all of it, from the first account setup decision to the full paid growth system, in my ebook Substack 101: A No-Fluff Guide to Building and Growing a Paid Newsletter. It is $27 at ballenpublishing.com and covers 16 chapters including paywall strategy, pricing psychology, Notes, video, podcasts, recommendations, and a 30-day launch plan. If you are building a Substack and want to do it right from the start, that is the roadmap.
