Average Internet Speed in Czechia

Internet in Czechia: what the data shows

At a median 37.2 Mbps download, Czechia sits in the upper half of the table: #55 of 119 ranked countries, 10% above the global median of 33.9 Mbps. The world's fastest median belongs to the United States at 144 Mbps, about 3.9× faster.

The median upload is 20.2 Mbps, about 54% of the download rate: the balance typical of a market mixing fibre with cable or DSL plans. Median latency is 49 ms. That works for streaming and browsing, though competitive gaming and video calls will feel it.

T-Mobile Czechia tops the measured providers at 78 Mbps, about 2.1× the national median, so switching networks can matter as much as switching plans.

Desktop and mobile tests land close together (34 and 39 Mbps), so the experience translates across devices; mobile accounts for 58% of tests. By operating system, Mac OS devices record the quickest median (60 Mbps) while Linux sits at 24 Mbps, usually a proxy for the networks and hardware each platform rides on rather than the software itself.

Tests from Czechia most often reached the Vienna test server (59% of the top-server mix), so the figures reflect the routes everyday traffic actually takes. Every number on this page is a median of single-stream browser tests from the H1 2026 window: Real-World Speed, measured on the open internet rather than inside an ISP's own network. It reads lower than peak-rate tests by design, and every country is measured with the same ruler.
