Getting your creative assets ready for a campaign? Use this guide to find the recommended formats, dimensions, file sizes, and video lengths for the most common ad placements across Meta, Google, YouTube, TikTok, and other major platforms. **Our recommendation:** When possible, provide both vertical and square creative, plus landscape video for YouTube. Keep videos engaging, lead with your strongest hook, and make sure your message comes across quickly. ## Quick Creative Guidelines - **Vertical video:** 1080 × 1920 (9:16). Best for Stories, Reels, TikTok, Snapchat, and YouTube Shorts. - **Square creative:** 1080 × 1080 (1:1). A versatile option for feeds across Meta and other platforms. - **Landscape video:** 1920 × 1080 (16:9). Standard for YouTube and in stream placements. - **Video length:** Shorter is often better. Aim for 15 to 30 seconds for most social campaigns, with the hook or key message in the first five seconds. - **File formats:** MP4 is a reliable default for video, while JPG and PNG work well for static images. - **Safe zones:** Keep important text, logos, and calls to action away from the edges, especially in vertical placements. ## Meta: Facebook and Instagram | Placement | Recommended Specs | Video Length | Best Practices | | --- | --- | --- | --- | | Facebook Feed | 1080 × 1080 (1:1) or 1080 × 1350 (4:5) | Flexible | Use captions and make the message clear without sound. | | Instagram Feed | 1080 × 1080 (1:1) or 1080 × 1350 (4:5) | Flexible | Vertical 4:5 creative uses more feed space. | | Facebook Stories | 1080 × 1920 (9:16) | Flexible | Full screen vertical.
