Use-case guide
Social Media Ad Image Sizes: Instagram, Facebook, LinkedIn, Snapchat, and Google Display
Ad creative that does not meet a platform's size specifications gets rejected, auto-cropped, or delivered with reduced reach. When you are paying for every impression, a wrong-sized image is not just an aesthetic problem — it is wasted budget. Each ad platform has strict requirements, and they differ enough that you cannot reuse one creative everywhere without adjustments. This guide organizes ad image sizes by platform so your design team or media buyer can reference exact specs when building campaign assets. From Instagram feed ads to Google Display banner variations, every dimension is here in one place.
Instagram Ads
Instagram ads appear in the feed and in stories. Feed ads follow the same dimensions as organic posts (square or 4:5), while story ads use the full-screen 9:16 format. Getting these right ensures your paid content blends seamlessly with organic content.
| Platform | Size Name | Dimensions | Ratio |
|---|---|---|---|
Instagram | Instagram Ad — Feed | 1080 × 1080px | 1:1 |
Instagram | Instagram Ad — Story | 1080 × 1920px | 9:16 |
Facebook Ads
Facebook offers more ad placements than any other platform — feed, stories, carousel, sidebar, and more. Each placement has its own optimal dimensions. Carousel cards are square, feed ads are landscape, and story ads are vertical.
| Platform | Size Name | Dimensions | Ratio |
|---|---|---|---|
Facebook Ads | Facebook Ad — Feed | 1200 × 628px | 1.91:1 |
Facebook Ads | Facebook Ad — Carousel Card | 1080 × 1080px | 1:1 |
Facebook Ads | Facebook Ad — Story | 1080 × 1920px | 9:16 |
LinkedIn Ads
LinkedIn ads target professional audiences and typically feature higher production values. Sponsored content appears in the feed alongside organic posts, while message ads display in LinkedIn Messaging with a smaller banner image.
| Platform | Size Name | Dimensions | Ratio |
|---|---|---|---|
LinkedIn Ads | LinkedIn Ad — Sponsored Content | 1200 × 627px | 1.91:1 |
LinkedIn Ads | LinkedIn Ad — Message Ad | 300 × 250px | 6:5 |
Snapchat Ads
Snapchat ads are full-screen vertical experiences that appear between stories and in Discover. The vertical format demands creative that is designed mobile-first with bold visuals and minimal text.
| Platform | Size Name | Dimensions | Ratio |
|---|---|---|---|
Snapchat | Snapchat Ad | 1080 × 1920px | 9:16 |
Google Display Ads
Google Display Network ads come in standardized IAB sizes that run across millions of websites. Unlike social ads, these have fixed pixel dimensions with no responsive cropping — what you design is exactly what displays. The most common sizes are listed here.
| Platform | Size Name | Dimensions | Ratio |
|---|---|---|---|
Google Display Ads | Google Display Ad — 300×250 Medium Rectangle | 300 × 250px | 6:5 |
Google Display Ads | Google Display Ad — 728×90 Leaderboard | 728 × 90px | 8.09:1 |
Google Display Ads | Google Display Ad — 160×600 Wide Skyscraper | 160 × 600px | 4:15 |
Google Display Ads | Google Display Ad — 320×50 Mobile Banner | 320 × 50px | 6.4:1 |
Google Display Ads | Google Display Ad — 336×280 Large Rectangle | 336 × 280px | 6:5 |
Google Display Ads | Google Display Ad — 970×90 Large Leaderboard | 970 × 90px | 10.78:1 |
Tips
- Design ad creative at the exact recommended dimensions — do not rely on platform auto-resizing. Ad managers often reject or deprioritize creative that needs to be transformed.
- Keep text under 20% of the image area for Facebook and Instagram ads. Both platforms still penalize text-heavy creative with reduced delivery, even though the hard rule was officially relaxed.
- Always preview your ads on mobile before launching. Over 80% of social media ad impressions are on mobile devices, and what looks great on a desktop preview can be unreadable on a phone.
Frequently asked questions
What is the best image size for Facebook and Instagram ads?
For feed ads, use 1080×1080 (square) as your starting point — it works on both platforms. For maximum engagement on Instagram, test 1080×1350 (4:5 portrait) which takes up more screen space. For stories on both platforms, use 1080×1920 (9:16).
Do I need different images for each Google Display ad size?
Yes. Google Display ads are fixed-size banners — a 728×90 leaderboard and a 300×250 medium rectangle are completely different layouts that require separate designs. You cannot stretch or crop one to fit the other. Most campaigns run at least 3-4 sizes to maximize reach across the Display Network.
What file formats do social media ad platforms accept?
Most social platforms accept JPG and PNG. Use JPG for photographic ads to keep file sizes small, and PNG for graphic ads with text overlays and flat colors to maintain sharp edges. Google Display also accepts GIF and HTML5 for animated ads. Keep file sizes under 150KB for Google Display and under 30MB for social platforms.
