Lead with the product, not the logo
Facebook feed ads get scrolled past in under a second — a recognizable product shot outperforms a branded lockup nearly every time, especially in a feed already dense with other product photography.
Facebook ads, sized right the first time
Feed, Stories, Marketplace, and the shrinking desktop right column each want a different crop. Describe the product, pick the placement, and generate a Facebook-ready ad without opening a design tool.
Specs
Facebook ad formats and sizes
Meta updates crop guidance often, but these four placements cover the overwhelming majority of Facebook ad spend today.
| Placement | Aspect ratio | Recommended size | Notes |
|---|---|---|---|
| Feed (mobile & desktop) | 1:1 or 4:5 | 1080×1080 or 1080×1350 | Square is the safer default; 4:5 claims more vertical space on mobile. |
| Stories & Reels | 9:16 | 1080×1920 | Full-bleed vertical — keep text and logos inside the safe zone. |
| Right column (desktop) | 1:1 | 1200×1200 | Small unit; needs a bold headline more than fine detail. |
| Marketplace | 1:1 | 1080×1080 | Product-forward imagery consistently outperforms lifestyle shots here. |
Research
What the Meta Ad Library actually shows you
Meta's official Ad Library is the deepest of the platform transparency tools — searchable by page, country, and active status, with a dedicated guide covering how to read it. It's a reliable way to confirm a competitor is running an ad and roughly how long it's been live.
What it won't do is hand you a file. Every result is a locked screenshot or video pulled straight from the feed — there's no dimension data, no editable layers, and no way to adapt what you're looking at into a placement you actually need. You can study the idea, but recreating even the layout means starting from a blank canvas in a separate design tool.
Limits
What it does not give you
A finished ad, sized and ready to upload. The library is a research tool for auditing what's already live, not a production tool for building what comes next — that gap is exactly what a generator is for, and it's the reason most teams end up switching tools halfway through a campaign brief.

Generate a Facebook ad instead of researching one
Start with the product and the offer, not the placement. AdLibrary.net's generator asks for a plain-language brief, a Meta feed or Story placement, and one of five proven angles — then produces a headline, primary text, and a creative sized for that exact spot in the feed, without a design pass or a separate cropping step afterward.
Not happy with the first pass? Generate it again — swap the color story, tighten the headline, or shift the angle from offer-led to social proof — without rewriting the whole brief. Most teams land on a usable version within two or three regenerations.
Creative Tips
Four things that make these ads perform
Square first, vertical second
If you're only generating one asset, 1:1 is the safer bet — it holds up across feed, Marketplace, and the right column without recropping, which matters most when you're testing several offers at once.
Keep primary text under two lines
Meta truncates long primary text on most devices; the strongest hook usually lives in the first eight to ten words, well before the 'see more' link ever gets tapped.
Design the safe zone for Stories
Anything within 250px of the top or bottom edge risks getting covered by the profile name, CTA button, or reply bar, so keep the core message centered in the middle third of the frame.
Facebook FAQ
Facebook ad generator, answered
Does this replace Meta's own Ad Library?
No — they answer different questions. Meta's tool shows you what's already running; this one generates a new ad from your own brief. Many teams use both: Meta's library for research, this generator for production, switching between the two depending on which stage of the campaign they're in.
What size should my main Facebook feed ad be?
1080×1080 (1:1) is the safest single size — it holds up in feed, Marketplace, and the desktop right column without a second crop. If you only need one asset, start there and add a Story-sized version later if the campaign needs it.
Can I generate both Feed and Story versions of the same ad?
Yes. Generate the feed version first, then regenerate with the Story placement selected — the brief carries over, only the canvas and crop change, so the product, offer, and angle stay consistent across both versions.
Does the generator write the ad copy too?
Yes. Based on your brief and chosen angle, it drafts a headline and primary text alongside the creative — both fully editable before you use them, so you can adjust tone or length without regenerating the image itself.
Is Instagram covered under the Facebook placement?
Meta feed placements share the same 1:1 and 4:5 specs across Facebook and Instagram, so a Facebook feed generation is Instagram-ready without changes, though Stories on either platform should use the 9:16 placement instead.
