Feathr supports two distinct creative environments: Display advertising and Meta advertising.
Please note that while Mobile Geofencing campaigns are display advertising, this campaign type requires a unique set of specifications due to the use of exclusively mobile ad placements.
For tips on what goes in your creative (messaging, layout, contrast), see Best Practices for Designing Creatives.

Mobile Geofencing Campaigns
Mobile Geofencing campaigns (not Historical Geofence campaigns) target people on their phones and tablets while they're physically inside a geofenced area, so Geofencing creatives need to work at mobile and small-tablet sizes. Please use this set of specifications for Mobile Geofencing campaigns.
Most Popular Mobile Geofencing Sizes
| Size | Dimensions | Ratio |
| Medium Rectangle | 300 × 250 | 6:5 |
| Pull | 320 × 50 | 6.4:1 |
| Mini-Leaderboard | 300 × 50 | 6:1 |
| Large Rectangle | 336 × 280 | 6:5 |
| Mobile Interstitial | 320 × 480 | 2:3 |
All Other Mobile Geofencing Sizes
| Size | Dimensions | Ratio |
| Leaderboard | 728 × 90 | 8.09:1 |
| Wide Skyscraper | 160 × 600 | 0.27:1 |
| Banner | 468 × 60 | 7.8:1 |
Note: Because Geofencing creatives run exclusively on mobile devices and tablets, Ad Tag creatives aren't supported for Geofencing campaigns.
Historical Geofencing is different. Because Historical Geofencing campaigns retarget people after they've left the geofenced area, their audience may be browsing from any device, not just mobile. If you're running a Historical Geofencing campaign, you're not restricted to the mobile-optimized sizes above; the Display sizes earlier in this article are fair game too.
Pixl+ Meta Campaigns (Facebook and Instagram)
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
- 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
Meta Creative Sizes (Static and Video)
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
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 |
| Facebook & Instagram Stories/Reels | 1080 × 1920 | 9:16 |
| Facebook & Instagram Feed/Stories | 1920 × 1080 | 16:9 |
| Facebook & Instagram Feed | 1200 × 628 | 1.91:1 |
Common Questions
-
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.
