Why this page exists

 

Every marketer knows the pain. You’re about to launch a campaign, but suddenly Instagram changes its story specs. Or Amazon updates its retail media banner sizes. Or the printer calls: your catalogue file doesn’t have bleeds.

Chaos, again.

 

Specs change constantly. Teams scramble. Designers copy-paste the same assets into endless formats. It’s a mess — and it shouldn’t be.

 

This library is here to kill that chaos.

 

It brings together every major ad spec — social, retail media, display, and print — into one place. Updated regularly. Easy to reference. Easy to trust.

 

And more importantly: it shows why specs should live inside one system. Because whether it’s TikTok, Tesco, or a tabloid ad, the inputs are the same: data, rules, templates.

 

One system. Any channel.​​

 

Social media ad specs 

 

From Instagram Stories to TikTok TopView, social ads are where specs change fastest. Get dimensions, ratios, file limits, and runtimes in one glance.

Retail media ad specs 

 

Retail media networks (RMNs) are exploding. Amazon, Walmart Connect, Target, Carrefour, Tesco, Zalando — each with their own formats, headline rules, and image sizes. If you sell in retail, this is your new battleground.

Display and video ad specs 

 

The classics still matter. Google Display Network banners, YouTube video ads, web standard sizes. They’re not sexy, but they’re everywhere.

Print ad specs 

​

Print never went away. Catalogues, posters, shelf wobblers, packaging, out-of-home. They all have specs — and mistakes cost money.

Why specs matter

 

Specs are more than numbers. They’re the rules that keep your brand visible, compliant, and consistent across every channel.

 

• Miss a safe zone? Your tagline gets cropped.

• Ignore bleed? You reprint 50,000 copies.

• Forget a file size limit? Your ad doesn’t run.

 

Specs are the plumbing of marketing. They’re boring — until they break.

 

The smart move isn’t memorizing them. It’s building a supply chain that outputs them automatically, across every channel.

 

That’s why this library exists: to give you the reference, and to push for the bigger fix.
