Feathr supports three distinct sets of creative specifications: Display Ads, Mobile Geofencing, and Meta. Not sure which set your campaign needs? Start with the campaign type lists in the Display Ads section, and go from there.
Tip: You don't have to memorize any of these sizes! The Creatives step in your campaign lists the accepted sizes and file requirements, so you can always check there while you build your campaign. If the size you want to use isn't listed in your campaign, then it's not a compatible size for that campaign type.
For tips on what goes in your creative (messaging, layout, contrast), see Best Practices for Designing Creatives.

Display Ads
Display ads are image and video ads shown across the general web. The specs in this section apply only to the campaign types listed below.
Campaigns that use Display Ads specs
Use the Display Ads specs for these campaign types:
- Pixl Plus (Display Advertising channel)
- Retargeting
- Email Mapping
- Lookalike
- Search Keyword
- Affinity
- Historical Geofencing
Campaigns that don't use Display Ads specs
These campaign types have their own specs. Keep reading further down this article for the right sizes:
- Mobile Geofencing: See Mobile Geofencing Campaigns.
- Pixl Plus (Meta Advertising channel for Facebook and Instagram): See Pixl+ Meta Campaigns.
Remember: Pixl Plus has two channels with different specs. The Display Ads specs in this section only apply to the Display channel of a Pixl Plus campaign. Creatives for the Meta channel must follow the Meta specs instead. If your campaign runs on both channels, add creatives for each. In the Creatives step, look for the Display Ads list for this channel and the Meta Creatives list for Meta.

Mobile Geofencing Campaigns
Mobile Geofencing campaigns target people on their phones and tablets while they're physically inside a geofenced area, so Mobile Geofencing creatives need to work at mobile and small-tablet sizes. Please use only this set of specifications for Mobile Geofencing campaigns.
Tip: If you're looking for Historical Geofencing creative specifications, go back to the Display Ads section above!
File requirements - Mobile Geofencing
- Image formats: JPG, PNG, GIF
- Max file size: 30MB (4MB for image creatives served by Google)
- Video formats: MP4, WebM
- Video codec: H.264 recommended

Note: Because Geofencing creatives run exclusively on mobile devices and tablets, Ad Tag creatives aren't supported for Geofencing campaigns.
Pixl+ Meta Campaigns (Facebook and Instagram)
The specs in this section apply only to the Meta Advertising channel in Pixl Plus campaigns. If your Pixl Plus campaign also runs on the Display channel, those creatives follow the Display Ads specs instead.
Meta creatives have their own file types, size limits, and dimensions. Meta also enforces its own content requirements beyond file specs (for example, keeping text under 20% of the image area), so it's worth a look at Meta's guidelines directly before you design, especially if this is your first Meta campaign in Feathr.
File requirements - Meta
- Image formats: JPG, PNG — max file size 20MB
- Video formats: MP4, GIF — max file size 1GB — H.264 codec recommended
- Text rule: keep text under 20% of the total image or video-thumbnail area
Creative Sizes (Static and Video) - Meta
We recommend adding at least one square creative.
| Size | Dimensions | Ratio |
| Standard Square | 1080 × 1080 | 1:1 |
| Vertical Image | 1080 × 1350 | 4:5 |
| Landscape Image | 1920 × 1080 | 16:9 |
| Standard | 1200 x 628 | 1.91:1 |
Meta video creatives follow the same placement/ratio breakdown as the table above, and also require:
- Pixel aspect ratio: square pixels
- Frame rate: fixed
- Scan type: progressive
- Duration: 5 seconds to 2 minutes
- Audio: stereo AAC, 128kbps+ (optional, recommended)
- Captions: optional, recommended
Full Placement Specs - Meta
If you want to fine-tune creative for a specific Meta placement (Feed vs. Stories/Reels), or want extra resolution headroom beyond the sizes above, here's the fuller breakdown by placement:
| Placement | Dimensions | Ratio |
| Facebook & Instagram Feed | 1080 × 1080 | 1:1 |
| Facebook & Instagram Feed | 1080 × 1350 | 4:5 |

Common Questions
How do I know which sizes my campaign accepts?
Check the Creatives step of your campaign. Every campaign lists its accepted sizes and file requirements right there.
Why isn't my creative uploading?
Double check that your file matches one of the accepted sizes above exactly, and that it's within the file size limit for its campaign type.
If the upload window isn't appearing at all, disable your browser's pop-up blocker and refresh.
Can I use an HTML5 ad?
Not as a raw HTML5 file upload; Feathr doesn't accept HTML5 assets directly. The only way to bring HTML5 creative into a campaign is through an Ad Tag built with an external tool (like Google Web Designer or Creatopy). Read How to use Ad Tags in Feathr Campaigns before you start down that path — it's a more involved setup than a standard creative upload.
Where do I get help designing creatives if I don't have a designer?
Start with Feathr's Canva template library! It's built around the sizes in this article, so you can go from template to upload-ready without custom design work.
How can I preview my creative?
In the Creatives step of your campaign, hover over the creative and click the options button (⋯). Select Edit within the options to preview your creative.
In your Project Content, navigate to your Creatives. Click the options button (⋮) next to the creative, and select Edit to preview your creative.
