Quick answer: Set your campaign objective in Meta Ads Manager, select Instagram Reels placement, upload a 9:16 creative at 1440x2560px, keep text out of the bottom 35% of the frame, and launch. Video with audio is the highest-performing format.

What Are Instagram Reels Ads?
Reels ads are fullscreen vertical placements built for mobile-first audiences. They appear between organic content, reaching viewers already in an active, high-intent browsing mindset.
Fullscreen vertical format
Reels ads take over the entire screen. No sidebars. No competing content. Just your creative at 9:16 aspect ratio, front and center.
Placement between organic Reels
Viewers see your ad between Reels from accounts they already follow. They can like, comment, save, share, or skip. It mirrors the organic experience exactly, which keeps friction low.
Why Reels matter for advertisers
Per Meta's Ads Guide, video Reels ads with audio and 9:16 format deliver 2x higher delivery and 34.5% lower cost per result compared to image-only ads. That is a meaningful efficiency gain for the same budget.

Instagram Reels Ad Specifications
Get the specs right before you upload. Wrong dimensions mean cropped creative and wasted spend.
Aspect ratio and resolution requirements
- Aspect ratio: 9:16 (required for native Reels format)
- Recommended resolution: 1440 x 2560 pixels
- Minimum width: 500px for images and videos 30 seconds or longer. 250px for videos under 30 seconds.
Safe zone guidelines
Per Meta's Ads Guide, keep these areas clear of text, logos, and key creative elements:
- Top: 14% of frame height
- Bottom: 35% of frame height
- Sides: 6% of frame width on each side
The bottom 35% is the most critical area. Meta's UI elements (profile name, CTA button, caption) overlay that zone and will cover anything placed there.
File format and size limits
Images: JPG or PNG. Maximum file size 30MB.
Video: MP4 or MOV. H.264 compression required. Stereo AAC audio at 128kbps or higher. Maximum file size 4GB. Duration up to 15 minutes.

How to Create Instagram Reels Ads in Meta Ads Manager
Follow these six steps to get your Reel live.
Step 1: Set up your campaign and select placements
Open Meta Ads Manager and click "Create." Choose your campaign objective (Awareness, Traffic, Engagement, Leads, or Sales). At the ad set level, select Advantage+ placements to include Reels automatically. Or choose manual placements and tick Instagram Reels under "Stories and Reels." Meta recommends at least six placements for optimal delivery.
Step 2: Choose your creative format
At the ad level you have three paths. Upload new creative. Promote an existing Reel from your Instagram profile. Or enable Advantage+ Creative for automated optimization across your uploaded assets.
Step 3: Upload or select your Reel
Upload your 9:16 MP4, MOV, JPG, or PNG. Check that your safe zones are clear before moving on. Add primary text (44 characters max for best display).
Step 4: Use Advantage+ Creative features
Advantage+ Creative can expand images to 9:16 if you upload a different ratio. It also adds royalty-free music from Meta Sound Collection. Select a track manually or let Meta choose one automatically.
Step 5: Set up targeting and budget
Define your audience at the ad set level. Set a daily or lifetime budget. Choose your bid strategy. Reels ads run on the same auction system as all Meta placements.
Step 6: Review and launch
Use Ads Manager Preview to check your creative in the Reels placement. Verify safe zones are clear. Confirm your creative contains no licensed music, face or camera effects, GIFs, product tags, or videos with edit lists. Those formats are not supported and will block delivery. Publish when ready.

Creative Best Practices for Reels Ads
Good specs are the floor. Strong creative is the ceiling.
Video with audio outperforms image-only ads
Meta's own data shows video with audio gets 2x higher delivery. Add original audio or a track from Meta Sound Collection. Captions are optional but recommended for viewers watching on mute.
Keep key messages in safe zones
Place your brand name, product shot, and headline inside the safe area. Anything outside risks being covered by Meta's UI overlay.
What not to include in Reels ads
Avoid licensed music, face or camera effects, GIFs, product tags, and videos with edit lists or special file containers. Each of these will prevent delivery.
Using existing Reels vs. creating new ads
Promoting an existing Reel is faster if you already have strong organic content. Creating a new ad gives you full control over specs, copy, and framing from the start.
