Video for social media: guide to formats and best practices

Complete guide to video formats for social media in 2026: dimensions, durations, best practices by platform.

Mastering video formats on each platform

Each social network has its own codes, formats, and algorithms. Posting the same video everywhere without adapting it is the most common mistake brands make. In 2026, a successful video strategy requires production that is designed natively for each platform.

Instagram Reels: the king of formats

9:16 format, ideal length of 15 to 30 seconds for maximum reach (up to 90 seconds possible). The hook must captivate within the first 2 seconds. Subtitles are essential because 85% of users watch without sound. Favor a fast pace with dynamic cuts every 2-3 seconds.

TikTok: Authenticity and Trends

9:16 format, 15 to 60 seconds long for best performance. TikTok values authenticity and content that appears spontaneous, even when professionally produced. Follow current video trends and viral formats. The algorithm favors content that generates shares and comments.

YouTube: structured long-form content

16:9 format for standard videos, 9:16 for Shorts. On YouTube, production quality makes all the difference: 4K resolution, professional sound, careful color grading. Videos between 8 and 15 minutes long perform best in terms of watch time. YouTube Shorts under 60 seconds serve as a gateway to your channel.

LinkedIn: expertise and added value

Format 1:1 or 16:9, duration from 30 seconds to 3 minutes. LinkedIn favors high-value content: customer testimonials, business expertise, behind-the-scenes company footage. The tone is more professional but should remain human and engaging. Corporate videos with people speaking to the camera generate the most interaction.

Optimize multi-platform production

The key is to think multi-format from the moment you start shooting. Film in 4K to give yourself the flexibility to crop. Allow for safety zones for different aspect ratios. Shoot short, standalone sequences that work on their own. And work with an audiovisual production studio that understands the codes of each platform to maximize the impact of your investment.

The metrics that matter

Don't just focus on views. Completion rate, engagement rate, shares, and saves are much more relevant indicators of your videos' performance. Analyze these metrics by platform to refine your video content strategy. Contact us for a customized strategy.
