TL;DR: Pick your format, nail the specs, open with a strong hook, build your campaign in Meta Ads Manager, and test variations to scale what works.
Instagram video ads run across Feed, Stories, Reels, and Explore. Each placement has its own specs and viewer behavior. Get these right and your creative does the heavy lifting.
What Are Instagram Video Ads?
Instagram video ads are paid placements that reach targeted users across the platform's main surfaces.
Why video ads matter on Instagram
Video holds attention longer than static images. More time on screen means more chances to drive action. Instagram's algorithm rewards content that keeps users watching.
Video ad formats available (Feed, Stories, Reels, Carousel)
Four main placements: Feed, Stories, Reels, and Explore. Each delivers a different viewer experience. Per Meta's Ads Guide, you should customize creative per placement rather than running one asset everywhere.
Choose Your Video Ad Format & Specs
Pick your placement first. Specs follow from that choice.
Instagram Feed video ads (1080x1350px, 4:5 ratio, 15-30 seconds recommended)
Feed ads appear between posts in the main scroll. Target 1080x1350px at 4:5 ratio. Keep length between 15 and 30 seconds for best completion rates.
Instagram Stories video ads (1080x1920px, 9:16 ratio, up to 15 seconds)
Stories fill the full screen. Use 1080x1920px at 9:16. Recommended length is 15 seconds. Anything longer auto-splits into sequential 15-second cards. Viewers can swipe away at each break.
Instagram Reels ads (1080x1920px, 9:16 ratio, 15-30 seconds recommended)
Reels ads match organic Reels formatting: 1080x1920px, 9:16 ratio, 15 to 30 seconds recommended. Maximum length is 90 seconds, but shorter tends to perform better.
Technical specs: MP4/MOV format, max 4GB file size
Use MP4 or MOV with H.264 codec. Maximum file size is 4GB. Fixed frame rate only. Variable frame rates cause playback issues.
Create Your Video Content
Strong content beats perfect production every time.
Hook viewers in the first 2 seconds
Your opening frame is your ad. If it does not grab attention immediately, viewers scroll. Lead with your strongest visual claim. No slow builds.
Design for sound-off viewing with captions and text overlays
Most Instagram users watch without sound. Add captions or on-screen text to every video. Your message should land even in complete silence.
Keep the primary message tight (125 characters max)
Meta's documentation states the primary text field caps at 125 characters. Headlines cap at 40 characters. Write your copy to fit, then tighten it further.
Follow safe zone guidelines for Stories and Reels (14% top, 20% bottom)
Keep critical text and logos out of the top 14% (~250px) and bottom 20% (~340px) of the frame. That space gets covered by Instagram's native UI.
Set Up Your Campaign in Meta Ads Manager
Open Meta Ads Manager and create a new campaign.
Choose your campaign objective (awareness, traffic, conversions, video views)
Instagram supports eight campaign objectives: brand awareness, reach, traffic, app installs, engagement, video views, lead generation, and conversions. Your objective tells Meta how to optimize delivery. Pick the one that matches your goal.
Define your audience and budget
Set targeting at the ad set level. Define location, age, interests, and behaviors. Set a daily or lifetime budget. Start with a test budget before scaling.
Select Instagram placements
Choose placements automatically or manually. Manual lets you select Feed, Stories, Reels, or a combination. Match the placement to the creative you built.
Upload & Launch Your Video Ad
Upload video file and add ad copy
Upload your video in Meta Ads Manager. Add primary text (125 chars max), a headline (40 chars max), and a destination URL. Check all fields before moving forward.
Preview on mobile before launching
Use the built-in preview tool to see your ad as a viewer would. Most Instagram traffic is mobile. Confirm text is legible, safe zones are clear, and the hook lands.
Monitor performance and optimize
Check delivery, video views, click-through rate, and cost per result within the first 48 hours. Flag anything underperforming early.
