Key takeaways
- Platform size matters far less than whether your audience is on it and reachable there.
- Reach differs from audience: some platforms show your posts to followers far less often than others.
- Pick two you can sustain rather than a presence on all of them that nobody maintains.
YouTube, Facebook, Instagram and WhatsApp are the most used social media platforms in 2026, and which of them comes first depends on how you count. Ask people, and Facebook leads. Count who opens the app on their phone, and YouTube leads. Count the audience each platform reports to advertisers, and YouTube leads again, with TikTok third. The table below puts the three measures side by side.
Which social media platform is the most used?
DataReportal’s Digital 2026 mid-year update (April 2026) ranks the platforms three ways. None of the three counts unique people, so read them as a guide to scale rather than an exact headcount.
| Rank | Used in the past month (GWI survey, Q4 2025) | Smartphone app use (Similarweb index, YouTube = 100) | Monthly ad reach (platforms’ own ad tools) |
|---|---|---|---|
| 1 | Facebook: 56.3% of internet users aged 16+ | YouTube: 100 | YouTube: 2.65 billion |
| 2 | YouTube: 55.3% | WhatsApp: 87.4 | Facebook: 2.39 billion |
| 3 | Instagram: 54.6% | Instagram: 80.5 | TikTok: 2.21 billion |
| 4 | WhatsApp: 54.4% | Facebook: 75.7 | Instagram: 1.99 billion |
| 5 | Messenger: 36.9% | TikTok: 67.4 | LinkedIn: 1.43 billion (registered members) |
LinkedIn’s figure counts registered members rather than monthly active users, so it is not comparable with the rest of that column. Across every platform, DataReportal counts 5.79 billion social media user identities at the start of April 2026. That is identities, not people: most people hold accounts on several platforms.
For a business the useful question is narrower: which of these does your audience use, and where can you keep posting every week? The overview below answers that per platform.
Quick Overview: 10 Major Social Media Platforms in 2026

- WhatsApp – More than messaging: groups, business, and channels.
