Baltimore County, MD Internet Speeds — Measured 2024
Real speed tests run in Baltimore County, Maryland during 2024 recorded a median download of 110.3 Mbps, upload of 35.4 Mbps and latency of 10.2 ms, across 49,874 measurements. That is 1.3× the US median and places it #235 of 2,425 US counties.
What these numbers mean here
The median is the typical connection, not the best one available. Half the tests in Baltimore came in below 110.3 Mbps and half above. The slower quarter of connections measured under 45.1 Mbps, while the faster quarter exceeded 261.2 Mbps — a spread that usually reflects a mix of fibre, cable and older DSL lines in the same area rather than one uniform service level.
At 110.3 Mbps down and 35.4 Mbps up, a typical household here can comfortably run several 4K streams alongside video calls. Latency of 10.2 ms is excellent for gaming and real-time calls.
