Key takeaways
- Buffer’s 1.8M-video study finds long-form and Shorts peak at almost opposite times (Sunday 10am versus Friday evening), so schedule them separately.
- Published studies show the general pattern, but your own audience’s activity is the more reliable signal — test and compare.
Best time to post on YouTube: what the research shows
- Buffer long-form (24 Jul 2026; 1.8 million videos): top slot Sunday 10am; Sunday, Tuesday and Monday the strongest days
- Buffer Shorts (same study): top slots Friday 4pm, 6pm and 7pm; evenings 6–11pm generally strong; Friday and Saturday the best days
- Sprout Social’s 2026 study does not include YouTube
One study, not two
With a single large study there is no second source to agree or disagree with, which is a limit rather than a finding. What Buffer’s data does show is that the two formats behave differently, so plan long-form and Shorts on their own patterns.
How to apply this
Treat Sunday morning for long-form and Friday evening for Shorts as tests, and compare them with your own channel’s analytics.

- Buffer’s 2026 study (1.8M videos, 24 July 2026) found Sunday at 10am the top slot for long-form. It is one study; Sprout Social’s study does not cover YouTube.
- Is the best time different for YouTube Shorts?
- Yes. Buffer found Shorts peak on Friday at 4pm, 6pm and 7pm, with evenings 6–11pm strong, almost the opposite of long-form.
- Should I treat these times as fixed?
- No. They are averages from one large study; compare your own channel’s analytics before committing.
