Meta accepts MP4 or MOV video (GIF in most placements) up to 4GB, with a 120×120 pixel minimum resolution for Facebook feed placements. Facebook feed video is recommended at 4:5 (1440×1800), with 1:1 (1440×1440) and 16:9 (1920×1080) also supported; Instagram feed is now recommended at full-height 9:16 (1080×1920). Stories and Reels ads are vertical 9:16 at a recommended 1440×2560, and Facebook in-stream ads run 16:9 or 1:1. Keep videos to roughly the recommended 15 seconds for most placements, and caption everything for sound-off viewing. ### What size should a Meta ads video be? It depends on the placement. Facebook feed: 4:5 at 1440×1800 (recommended), 1:1 at 1440×1440, or 16:9 at 1920×1080. Instagram feed: 9:16 at 1080×1920 — the only ratio in Meta's current placement spec. Stories and Reels on both apps: 9:16 at a recommended 1440×2560. Facebook in-stream: 16:9 at 1920×1080 or 1:1 at 1080×1080. When one video must serve several placements, 4:5 travels best in the Facebook feed, while Instagram feed, Stories, and Reels need true vertical 9:16. ### What is the maximum length and file size for a Meta video ad? The maximum file size is 4GB across Meta video placements. Length limits vary by placement: Facebook feed video can technically run up to 241 minutes, Instagram feed and Instagram Stories up to 60 minutes, Facebook Stories up to 3 minutes, and Instagram Reels up to 15 minutes (Meta lists no fixed maximum for Facebook Reels ads). Facebook in-stream ads run 5–15 seconds on desktop and 5 seconds to 10 minutes on mobile. Meta notes duration limits can also vary by campaign objective and destination, so confirm your combination in Ads Manager. In practice, keep most placements to roughly the recommended 15 seconds — completion rates fall sharply beyond that. ### Are video specs the same for Facebook and Instagram? Mostly. Both share the 4GB file cap, MP4/MOV file types, and identical 9:16 Reels and Stories dimensions (1440×2560 recommended). The differences are in feed formats and duration: Facebook feed is recommended at 4:5 with a 120×120 minimum resolution and a 241-minute maximum, while Instagram feed is recommended at 9:16 (1080×1920) with a 60-minute maximum. Facebook Stories cap at 3 minutes versus 60 minutes for Instagram Stories, and Facebook additionally offers in-stream placements (5–15 seconds on desktop, up to 10 minutes on mobile). ## Full Interactive Guide See the complete interactive specifications with placement tables at [/resources/guides/meta-ad-creative-video-specs-guide](/resources/guides/meta-ad-creative-video-specs-guide).
