Facebook Ad Image Size Guide — Specs & Best Practices

Running Facebook ads with the wrong image size is one of the fastest ways to waste your budget. Blurry creatives, cropped headlines, cut-off product shots, and text hidden behind CTA buttons all reduce click-through rate and increase cost-per-click — before your audience even reads your copy.

Facebook uses different image specs for every ad placement: feed, Stories, Reels, carousel, right column, Marketplace, and Audience Network. Each one has a different aspect ratio, minimum resolution, and set of UI overlays. This guide covers every spec you need, the most common creative mistakes, and how to check your images before launching a campaign.

Standard Facebook Ad Image Sizes

Facebook supports multiple ad placements, and each one has different image requirements. Using the wrong size results in automatic cropping, blurry rendering, or rejected creatives.

Use the Facebook image size checker to verify your dimensions match the placement before uploading to Ads Manager.

How Facebook Crops Ad Images

When your ad image doesn't match the target aspect ratio, Facebook auto-crops from the center. But cropping isn't the only way content gets hidden — Facebook also layers UI elements on top of your image that you can't remove.

What gets overlaid on ad images

• CTA button — "Learn More," "Shop Now," "Sign Up," and other call-to-action buttons appear at the bottom of feed ads, covering the lower 10-15% of the image.
• Headline and description — ad copy appears below the image in feed placements, but on some mobile layouts it overlaps the bottom edge.
• "Sponsored" label — appears at the top of the ad, near the advertiser name. Avoid placing small text in this area.
• Story/Reels UI — swipe-up CTA, profile info, and reaction buttons cover the top 15% and bottom 15-20% of vertical ad creatives.

The safe zone for feed ads is roughly the center 80% of the image. For Story and Reels ads, keep key content in the middle 60-70% of the vertical space. Use the safe zone visualizer to check what stays visible, and the ad image preview tool to see the full layout with overlays.

Cropping by placement

• Feed ads — center-crop to 1.91:1. Tall images lose top and bottom. Wide images are generally safe.
• Carousel ads — center-crop to 1:1 per card. Non-square images lose edges unpredictably.
• Story/Reels ads — no crop if uploaded at 9:16, but UI overlays hide edges.
• Right column — image renders very small (~254×133). Fine detail and small text become unreadable.

Pre-crop your images to the correct ratio with the Facebook image crop tool before uploading to Ads Manager.

Text Overlay Best Practices for Facebook Ads

Facebook officially removed the 20% text rule in 2021, but the algorithm still matters. Ad images with heavy text coverage consistently see reduced delivery, higher CPM, and lower reach. The algorithm deprioritizes text-heavy creatives even if they're technically allowed.

• Keep text under 20% of image area — this is no longer a hard limit, but it's still the threshold where delivery starts to drop. Check yours with the text overlay checker.
• Use bold, heavy fonts — thin fonts become unreadable at small display sizes, especially in right column and Audience Network placements.
• High contrast between text and background — white text on dark overlay or dark text on light area. Never place text directly on a busy photograph without a contrast layer.
• 3-5 words maximum — your ad copy handles the details. The image text should be a short hook, not a paragraph.
• Keep text away from edges — CTA buttons, "Sponsored" labels, and crop zones all eat into edge areas. Center your text in the safe zone.

How to Avoid Blurry Facebook Ads

Facebook compresses every image you upload. If your source file is already small, low-quality, or compressed, the additional compression makes it look noticeably blurry — especially on high-density mobile screens.

• Always upload at the maximum recommended size — 1200×628 for feed ads, 1080×1920 for Stories/Reels, 1080×1080 for carousel. Larger source files survive compression better.
• Use JPG at 90%+ quality for photos — don't pre-compress your images before uploading. Let Facebook handle the compression from a high-quality source.
• Use PNG for graphics with text and sharp edges — logos, text overlays, and illustrations render sharper as PNG because there are no JPG compression artifacts around edges.
• Avoid upscaling small images — stretching a 400px-wide image to 1200px doesn't add detail; it just makes the blur larger. Start with a high-resolution source.
• Check before launching — use the thumbnail analyzer to check resolution, quality, and sharpness before spending budget on a blurry creative.

Facebook Ad Creative Best Practices

Getting the size right is step one. Making the creative actually perform is step two. These principles consistently produce higher CTR and lower CPC across Facebook ad placements.

• One clear focal point — the viewer should immediately know what to look at. A single face, product, or bold text element. Cluttered creatives with multiple competing elements underperform.
• Faces outperform objects — ads with faces consistently get higher engagement. If your product involves people, show people using it.
• Bright, saturated colors stand out — the Facebook feed is dense. Muted, low-contrast images blend into the background. Bold colors stop the scroll.
• Design for mobile first — over 98% of Facebook users browse on mobile. If your ad doesn't work at small sizes on a phone screen, it doesn't work.
• Create placement-specific versions — don't use one image for every placement. A 1.91:1 feed image will be cropped badly in Stories. A 9:16 Story image won't work as a carousel card. Build separate creatives for each format.
• Test at thumbnail scale — your ad will often appear as a small thumbnail in the feed. If it's not compelling at 100×52 pixels, reconsider the design.

Tools to Check Your Facebook Ad Images

Check your ad creatives before launching a campaign. A 30-second preview can prevent wasted spend on a broken image.
