HDBaseT / HDMI Distance
Pick the transport (passive copper HDMI, HDBaseT 2.0 or 3.0), the resolution/rate and the cable category, and get the maximum typical video distance plus a cable recommendation. These are standard reference values: they vary by extender and cable quality.

How to read the table · assumptions
1. Passive HDMI: a direct HDMI
cable, no extender. Distance drops fast as resolution rises because of
copper attenuation.
2. HDBaseT 2.0 (class A) carries
up to 100 m for signals up to 10.2 Gbps
(1080p60, 4K30 4:4:4, 4K60 4:2:0). Above that, 4K60 4:4:4
uses compression and the usable length drops to ~40 m.
It does not support 8K.
3. HDBaseT 3.0 raises the
bandwidth: 4K60 4:4:4 and 8K30 reach
~100 m over Cat6A.
4. Cable category: HDBaseT distances are given
over Cat6A. With Cat6 subtract
~30 % and with Cat5e subtract ~40 %.

How it works
The tool estimates the typical maximum distance of a video signal by transport path: direct HDMI over passive copper (a single cable, no extender), HDBaseT 2.0 or HDBaseT 3.0 (extenders over twisted pair with RJ45). It matches the chosen resolution/rate (1080p60 ≈ 3 Gbps, 4K30 4:4:4 and 4K60 4:2:0 ≈ 8.9 Gbps, 4K60 4:4:4 ≈ 17.8 Gbps, 8K30 ≈ 32 Gbps) against the capacity of each path and warns when the combination is not supported, for example 8K over HDBaseT 2.0.
For HDBaseT the base distances are given over Cat6A (up to 100 m for signals up to 10.2 Gbps on 2.0; up to 100 m even for 4K60 4:4:4 and 8K30 on 3.0) and cable-category factors are applied: Cat6 subtracts about 30 % and Cat5e about 40 %. For passive HDMI the category does not apply and distance drops with resolution (about 15 m at 1080p60, about 5 m at 4K60). These are typical reference values: real reach depends on the extender chipset, cable quality and the installation.
Example: delivering 4K60 4:4:4 to a room 35 m away
- Passive HDMI will not make it: a direct copper cable manages around 5 m at 4K60.
- With HDBaseT 2.0 over Cat6A, 4K60 4:4:4 (≈17.8 Gbps) runs compressed and reaches about 40 m: just enough for the 35 m.
- With Cat6 the −30 % factor cuts the reach to about 28 m, not enough: for that distance run Cat6A or use HDBaseT 3.0 (100 m).
