How many people
use Tumblr in 2026?

How many active users does Tumblr have?

Tumblr’s advertising page lists 95 million global monthly active users, including 26 million in the US. The headline block does not state a measurement month.

The page cites older research elsewhere, but does not clearly attach those dates or a methodology to its monthly user totals.

How many Tumblr blogs and daily posts are there?

Tumblr’s press page lists 639.2 million blogs and 6.2 million daily posts. It does not identify the measurement date or the period used for daily posts.

Blog totals cannot establish how many people use Tumblr. Its account documentation allows a primary blog and additional sideblogs. The total also gives no indication of how many blogs are currently active.

To customize your blog’s own web address, choose from our free and premium custom HTML Tumblr themes.

The press page does not supply a cumulative post total. Multiplying its daily figure by the platform’s age would not produce a reliable one.

Who uses Tumblr?

The official pages give different Gen Z figures:

The Gen Z figures have no matching measurement dates, age boundaries or sampling details. The press page specifies active users; the advertising headline is less specific. The available information cannot establish whether the difference comes from timing, population or method. Neither figure should be used to calculate a Gen Z headcount from the monthly user total.

Which countries send the most traffic to Tumblr?

The United States accounts for 48% of desktop traffic in Similarweb’s August 2026 report.

Similarweb estimates website traffic. This country breakdown covers desktop visits and cannot describe the location of every Tumblr user, including those who use its apps. Repeat visits can come from the same person.

How many times has the Tumblr app been downloaded?

Google Play shows 100 million or more downloads for Tumblr’s Android app, displayed as 100M+ on 6 October 2026.

This is a cumulative store threshold. It does not measure current active users, downloads this year or iOS installations.

How large can a Tumblr Community be?

Tumblr’s help centre states a default limit of 10,000 members per Community, including pending invitations. Tumblr can adjust the limit for individual Communities.

Communities can be public or private, and members can publish directly or reblog into them. The limit is a product setting; it does not tell us how many people participate across all Communities.

How many Tumblr themes are available?

The Tumblr Theme Garden offers free and paid themes, with filters for layouts and uses such as single column, grid, text and high-resolution images.

According to Tumblr’s customisation guide, a custom theme applies to the blog’s own web address after custom themes are enabled. That is the part of a Tumblr blog that Peachfin’s Tumblr themes are designed for.

Who owns Tumblr, and did it move to WordPress?

Automattic owns Tumblr. Its company timeline records the acquisition from Verizon in 2019.

• 27 August 2024: Automattic announced work to run Tumblr’s backend on WordPress.
• 30 June 2025: In a Decoder interview, Automattic chief executive Matt Mullenweg said the migration had been put on hold.

An undated recruitment page still describes migration work. The migration to WordPress is not confirmed to be complete.

How these numbers are measured

Monthly active users, blogs, daily posts, website visits and app downloads count different things. They cannot be added together to estimate Tumblr’s audience.

Tumblr’s official figures are publisher statements with limited public methodology. Similarweb’s figures are traffic estimates for a stated month. Google Play reports a cumulative download threshold.
