UGC for Meta Ads: Formats, Specs, and Creative Structure

How to brief and edit UGC for Facebook and Instagram ads: placements and aspect ratios from Meta’s specs, safe zones, partnership ads, and a structure for ad-ready cuts.

By CreatorsUGC 10 min read

Quick answer

To run UGC on Facebook and Instagram, ask creators for a vertical 9:16 master with key text and faces kept out of the top 14%, bottom 35%, and outer 6% of the frame, plus a 4:5 version for Facebook Feed. Edit each video so the hook lands in the first seconds, the product appears early, and the call to action is spoken and shown. Then decide how it will run: from your own Page as a standard ad, or from the creator's handle as a partnership ad, which needs the creator's permission inside Meta's tools as well as a license in your contract.

This page is about producing for Meta: which formats Meta recommends for each placement, the specs to put in your brief, how partnership ads work, and an edit structure that turns one creator shoot into several ad-ready cuts. It doesn't cover TikTok's Spark Ads, which work differently (see UGC for TikTok ads), or how to judge the cuts once they're live (see how to test UGC ad creative). For the opening lines themselves, use the UGC hooks library.

Which aspect ratio each Meta placement wants

Meta places ads across Feeds, Stories, Reels, and other surfaces, and each one favors a different shape. Meta's Business Help Center publishes a placement-by-placement table. The rows that matter for creator video are below, as listed in October 2026.

PlacementRecommended ratio for videoWhat it means for UGC
Facebook Feed4:5Deliver a 4:5 cut. Meta notes that on desktop Facebook Feed, video shows at 1:1 and may get black bars.
Instagram Feed9:16The vertical master works. Keep the subject centered so it still reads if cropped.
Instagram and Facebook Stories9:16Full-screen vertical. Safe zones matter most here.
Instagram and Facebook Reels9:16Full-screen vertical. This is the native home for UGC-style video.
In-stream video (ads shown inside other videos)16:9, per Meta's aspect ratio best practicesOnly worth a horizontal cut if you plan to buy in-stream specifically.

In practice, two masters cover most UGC buys: 9:16 for Stories, Reels, and Instagram Feed, and 4:5 for Facebook Feed. Meta's guidance on aspect ratios says that when you don't upload every variation yourself, Ads Manager fills the gaps with padding, cropping, or AI expansion, and that uploading your own square, vertical, portrait, and horizontal versions "gives you the most control." It also recommends reviewing auto-generated crops before publishing so key content isn't cut off.

Brief tip

Ask the creator to frame the shot so the face and product sit in the middle of a vertical frame, with some headroom. A center-weighted 9:16 shot can be re-cropped to 4:5 in editing without losing the hook. If the creator holds the product at the very top or bottom of the frame, the 4:5 crop will cut it off.

Video specs to put in the creator brief

Meta's Ads Guide lists specs per placement. Most phones already record files that fit inside these limits, so the brief's job is to name the shape, resolution, and audio expectations. As listed in Meta's Ads Guide in October 2026:

SpecReels and StoriesFacebook Feed
Aspect ratio9:164:5
Recommended resolution1440 x 2560 px1440 x 1800 px
File typeMP4 or MOVMP4, MOV, or GIF
Maximum file size4 GB4 GB
CaptionsOptional but recommendedOptional but recommended
SoundOptional but recommended (Meta says "strongly" for Reels)Optional but recommended

Meta's Ads Guide also recommends H.264 compression, square pixels, a fixed frame rate, progressive scan, and stereo AAC audio at 128 kbps or higher. In plain terms, ask for a standard phone export at full resolution, not a screen recording or a file re-saved from a messaging app, which compresses video heavily.

Safe zones for Stories and Reels

On full-screen placements, the interface sits on top of your video: the profile name and icon at the top, and the caption, call-to-action button, and engagement icons at the bottom. Meta's Ads Guide for Instagram Stories and Reels says to leave roughly 14% of the top, 35% of the bottom, and 6% on each side free of text, logos, and other key creative elements.

On a 1080 x 1920 frame, that works out to about 270 px at the top, 670 px at the bottom, and 65 px on each side. The bottom zone is the one creators most often break: on-screen captions placed in the lower third will sit under Meta's own text and button.

  • Burned-in captions sit in the middle band of the frame, not the lower third.
  • Product close-ups, price callouts, and logos stay out of the top and bottom zones.
  • The creator's face is roughly centered vertically when they speak to camera.
  • Any text overlay you add in editing is checked in Ads Manager's placement preview before launch.

Partnership ads: running UGC from the creator's handle

Meta renamed branded content ads to partnership ads. According to Meta's developer documentation, a partnership ad features both the brand's and the partner's accounts in its header, and the ad uses signals from both accounts for ranking. Either account can be the primary identity. This is Meta's built-in version of what the industry calls whitelisting.

Per Meta's Business Help Center, you need permission from the partner whose handle the ad will include, and creators can revoke that permission at any time. There are two levels:

Permission typeWhat the advertiser can doBest for
Content levelPromote a specific post, story, or reel. If the creator shares a partnership ad code, you can create ads from any of their Instagram or Facebook posts, stories, or reels, branded content or not. Without a code, you can promote their existing content when the "Allow brand partner to boost" toggle is on and you're tagged in the paid partnership label. Meta says you can edit the content for the ad without changing the creator's original post.One-off projects and test campaigns
Account levelCreate partnership ads from the creator's handle without pre-existing content, create ads from any of their content that tags you (through the paid partnership label, an @mention, a people or product tag, or a collab), and include or exclude the creator's custom audience. Requests can be accepted in Partnership Ads Hub or in the Instagram or Facebook app.Ongoing creator relationships

Under both levels, Meta says the advertiser can hide comments on the ads it runs and on the creator's original post, and the creator can unhide them. Meta also notes an exception: if the same business owns both accounts and an employee has ads access to both, partnership ads can run without partnership ad permissions.

Two things the toggle doesn't cover

First, Meta's permission is a technical switch the creator can turn off at any time. Your contract has to say what you're licensed to do, for how long, and what happens when the term ends. See UGC usage rights for brands for the clauses. Second, Meta's creator documentation says content with licensed music added is not eligible for partnership ads. Brief creators to record without trending or copyrighted tracks if you might boost the post.

Partnership ad or a standard ad from your Page?

You don't need partnership ads to use UGC. If the creator delivers files and your license covers paid use, you can upload the video as a standard ad from your own Page. Here is how the two options compare:

Standard ad from your PagePartnership ad
Who appears in the headerYour brand onlyYour brand and the creator
What you need from the creatorThe video file plus a written paid-usage licenseA Meta permission (code or account level) plus a written license that covers running ads from their handle
Creator's ongoing involvementNone after deliveryTheir account must stay eligible and the permission must stay active
DisclosureThe ad is labeled as an ad. Testimonial rules still apply.Paid partnership labeling through Meta's tools, plus the ad label

Disclosure duties don't disappear because a video runs as an ad. If the creator speaks as a customer, the FTC's endorsement rules apply. FTC rules for UGC covers when and how to disclose.

An edit structure for ad-ready UGC cuts

A UGC video that works as an ad is usually assembled from modules, not filmed as one take. If you brief the creator to film each module separately, you or your editor can build several versions from one shoot. The structure below is a planning tool, not a formula Meta prescribes. Durations are starting points to adjust.

ModuleJobWhat to film
1. Hook (first 1–3 seconds)Stop the scroll and signal who it's forThree or more alternate openings: a spoken line, a visual action, and a bold claim the brand can substantiate
2. Context or problemMake the viewer recognize their situationOne or two sentences in the creator's own words
3. Product in useShow, don't tellClose-ups of the product working, unboxing, texture, before and during. Film plenty of b-roll.
4. Proof or detailAnswer the main objectionA specific feature, how it compares to what they used before, or a demonstration
5. Call to actionTell the viewer what to do nextSpoken CTA plus a clean end frame with space for text

Cuts to request from one shoot

  • Full-length 9:16 master with burned-in captions placed inside the safe zone.
  • Clean 9:16 master without captions or text, so your team can add its own overlays or localize.
  • 4:5 version for Facebook Feed, re-framed rather than letterboxed.
  • Hook swaps: the same body with each alternate opening (three hooks and one body gives you three ads).
  • A short cutdown that keeps the hook, the product in use, and the CTA.
  • Raw clips of every module, if your agreement includes raw footage.

Spell these out in the order. The UGC deliverables checklist has file-naming and acceptance criteria you can copy into the brief.

Illustrative example: one shoot, nine ads

A hypothetical brand selling a travel mug books one creator to film three hooks (a spoken problem line, a visual of coffee spilling in a car cup holder, and a "watch this" leak test), one shared body, and a CTA. The editor builds three full-length 9:16 hook swaps, the same three re-framed to 4:5 for Facebook Feed, and three short cutdowns that keep the hook, the leak test, and the CTA. That's nine ads from one shoot. Only the three hook swaps go into the first test, because they differ in exactly one thing. The ratio versions just let Meta serve each placement properly. The product and counts are invented to show the structure.

Template: Meta section of a creator brief
PLACEMENTS: Instagram Reels, Stories, Feed; Facebook Feed
SHAPE: Film vertical 9:16 at full resolution. Keep face and product
       centered so we can crop a 4:5 version.
SAFE ZONE: No text, logo, or product close-up in the top ~14%,
           bottom ~35%, or outer ~6% of the frame.
AUDIO: Clear voice, no background music, no licensed or trending tracks.
HOOKS: Film [3] different openings (lines below). Same body for all.
  Hook A: [LINE]
  Hook B: [LINE]
  Hook C: [VISUAL ACTION]
MODULES: Film each separately: problem / product in use / proof / CTA.
B-ROLL: [LIST OF SHOTS: close-ups, hands, texture, packaging]
CTA: Say "[CTA LINE]". Hold a clean final frame for 2 seconds.
DELIVER: 9:16 captioned, 9:16 clean, 4:5, hook swaps, raw clips [IF AGREED]
USAGE: [Paid ads on Meta, from brand Page / as partnership ads],
       [TERM], [TERRITORY]. See contract.
CLAIMS: Only say what you experienced. Do not say: [BANNED CLAIMS]

Common reasons UGC underdelivers on Meta

  • Captions under the interface. The video looks fine in the editor and broken in Reels. Check every placement preview.
  • Letterboxed 16:9 footage in vertical placements. A horizontal video shrinks to a strip in Stories and Reels. Film vertical from the start.
  • Slow opening. If the first seconds are a greeting or a logo, the hook is gone. Lead with the hook module.
  • One version only. With a single cut, you have nothing to compare. Hook swaps are the cheapest variations to produce.
  • Licensed music. It can block partnership ads and create rights problems for standard ads. Use voice plus music from a source your license covers.
  • Rights that don't match the plan. An organic-only license doesn't cover paid ads. Settle usage before the shoot, not after a video starts performing.

If you're running the same creators on TikTok, the mechanics differ: TikTok uses authorization codes with fixed durations rather than revocable account permissions. See UGC for TikTok ads.

If you still need the creators, you can post a brief on CreatorsUGC (our platform) and paste the Meta section above into it. Its Terms of Service include digital advertising use on Meta. Running ads from a creator's handle is a separate permission you arrange with the creator. The brands page explains how ordering works.

FAQ

Do I need a creator's Instagram account to run their UGC as a Meta ad?

No. If they deliver the video file and your contract licenses paid use, you can run it from your own Page. You only need their account, and their permission in Meta's tools, for partnership ads that show their handle.

Is "whitelisting" the same as partnership ads?

Whitelisting is an industry term for running ads through a creator's identity. On Meta, the official mechanism for that is partnership ads, which use content-level or account-level permissions.

Can a creator stop my partnership ad?

Yes. Meta says creators and partners can revoke partnership ad permissions at any time. Your contract can set a term and what each side owes if permission is withdrawn early, but it can't change how Meta's switch works.

Does UGC perform better than studio ads on Meta?

Meta doesn't publish a figure for that, and claims you'll see elsewhere rarely say whose account, product, or audience they came from. Treat it as a question for your own account: run a UGC cut against your current best ad in a proper A/B test. How to test UGC ad creative shows how to set that up.

How many UGC videos do I need for Meta ads?

Enough to compare at least two versions that differ in one way. Hook swaps from a single shoot are the cheapest way to get there. To plan the budget, see how much UGC costs.

Should I add captions?

Meta lists captions as optional but recommended. Many people watch with sound off, so burned-in captions inside the safe zone are a sensible default. Also ask for a clean version so you can change them later.
