Make a banner: pick the right kind, then make the whole set

Before you pick a tool, be clear about which banner you actually need. The three common meanings share a word and almost nothing else: not the units, not the resolution, not the file format, not the production route.

If you need the printed kind, stop here and take your artwork to a print shop at the physical size with bleed and 150 dpi or more. Nothing on this page applies to vinyl or mesh. The other two are screen graphics measured in pixels, and the third is where doing it by hand costs you the most time.

An ad banner gets roughly one second, usually at the edge of someone's attention, on a screen they are scrolling. That constrains the design far more than taste does, and it is why a banner that looks sparse next to your website is usually the one that performs.

Three elements, in a fixed order of importance: who is advertising (logo or wordmark, recognisable instantly), what is on offer (one headline, one price, or one product — not all three competing), and what to do next (a button that actually looks like a button). Anything beyond that dilutes the message. Body copy set at 11 px inside a 320×50 mobile strip is read by nobody.

Contrast decides legibility more reliably than font choice does: aim for at least 4.5:1 between text and its background, and never drop a headline onto the busy part of a photo without a panel or scrim behind it. Then keep the file small — display networks and ad servers commonly cap image ads at 150 KB and reject anything heavier, no matter how good it looks.

A single 300×250 fills one kind of slot. Real inventory is spread across desktop headers, in-content rectangles, sidebars and mobile strips, and every network has its own required list. Skipping formats does not save money; it quietly removes reach from a campaign you are already paying for. In affiliate programmes it is worse: publishers place whatever you supply, so a thin banner set means fewer placements and no way to know what you missed.

A practical minimum for display, then the additions each channel demands:

Making banners one at a time in a design tool is the reason most small advertisers run two sizes and then wonder why their reach is low. myfeedr removes the repetition. You enter your website address; the system loads the live page and reads the logo file, the colour values, the font families, the headline, the product names, prices and images; then it generates 38 formats in one pass — roughly two minutes, no briefing, no account.

You see watermarked previews for free and decide afterwards. Unlock the set and everything stays editable: headline and button copy, colours, the product or hero image including crop and zoom, and three layout variants per format. The download is a ZIP with PNG and JPG in every size plus 2× retina files, and a separate Google Ads pack for the responsive assets.

Layouts are chosen per aspect ratio rather than per format, which is what keeps the set coherent. A tall skyscraper stacks logo, headline and button; a mobile strip runs them side by side; a billboard gets the hero image. Type sizes are computed from the box and the actual length of your text, so a long product name shrinks instead of running off the edge.

Across the four channels the set divides as follows — the banner sizes reference lists every format individually, with its placement and its file limit.

Being straight about the limits: myfeedr makes static image banners. No animation, no HTML5 creatives, no video, no print files. If a campaign needs an expanding rich-media unit or a six-second bumper, that is a different tool and probably a designer.

It also cannot invent a brand. The output is only as good as what your website exposes: if there is no logo file, no distinct brand colour and no usable product images, the analysis has little to work from. You then set those values by hand in the editor — a couple of minutes of work, but still one round of it instead of 38.

And it does not write your offer. The generator picks up the copy that is on your page; whether "Free shipping from £50" or "New autumn collection" is the right thing to advertise this week is a decision only you can make. Editing the headline afterwards takes seconds and applies to every format at once.
