Shorts Length Is Changing
New analyses say there's no single 'magic' Shorts length anymore — optimal durations are shifting and platform tweaks mean creators must test formats and retention, not rely on a fixed runtime. (ytshark.com) (newsroompanama.com)
YouTube raised Shorts’ maximum runtime to three minutes for vertical/square uploads effective October 15, 2024, a change documented on YouTube’s support and blog pages. (support.google.com) YouTube also changed how Shorts views are counted on March 31, 2025 — a “view” now registers at the moment a Short starts to play or replay with no minimum watch time, while YouTube preserved a separate “engaged views” concept for meaningful watch-time metrics. (techcrunch.com) Data reviews from late 2024–2026 show there is no single optimal runtime: Shorts of 15–30 seconds commonly hit the highest retention rates (often above 80%), but the 50–60 second band has produced the largest average raw view totals (about 4.1 million average views) with completion rates near 76% in some analyses. (virvid.ai) Multiple platform analyses report that YouTube’s recommendation system prioritizes completion percentage and relative watch time over absolute seconds watched, meaning a shorter Short watched to completion can outperform a longer Short with poor retention. (opus.pro) Creator playbooks published in 2025–2026 recommend rigorous A/B testing of runtimes and formats, an attention-grabbing hook within the first three seconds, and the use of AI trimming and repurposing workflows to iterate quickly across multiple length bands. (opus.pro) YouTube’s early-2026 feed tweaks — including new Shorts search filters, popularity sorting and feedback changes — have already shifted discovery dynamics, prompting analysts to advise frequent small experiments on retention and session-extension signals rather than relying on one “magic” runtime.
