If you're trying to run an HDMI cable across your house, you might need a cable longer than recommended. For example, if you wanted to connect a TV or monitor to a computer in another room or farther away.
In this article, I'll discuss how long of an HDMI cable you should use and ways to extend an HDMI cable if you want it to reach farther.
Max HDMI Cable Length
Each type of HDMI cable has a limitation of how long it can reach. There's no specific "max" length a cable can go, but a limitation
from the material they're made with.
Most newer copper HDMI cables reach around 15 to 25 ft (5 to 7.5 m). HDMI cables made with fiber optic can reach much farther. On average, fiber optic HDMI cables can reach around 50 to 200 ft (15 to 60 m).
Below are the three types of copper HDMI cables with their average length limits and resolutions they can handle at their max cable length:
| Type | Max Cable Length | Speed | Supported Resolutions |
|---|---|---|---|
| Standard HDMI | 49 ft (15 m) | < 10 Gb/s | 720p 60 Hz | 1080i 60 Hz |
| High Speed HDMI | 15–25 ft (5–7.5 m) | 18 Gb/s | 1080p 60 Hz | 4K 30 Hz |
| Ultra High Speed HDMI | 10–15 ft (3–5 m) | 48 Gb/s | 4K | 5K | 8K | 10K 120 Hz |
Why HDMI Cables Have a Max Length
Most HDMI cables are made of copper, limiting the cable's length because it loses signal strength the farther it reaches. Signal loss can happen with cables made of other materials also. This signal loss (attenuation) is measured in decibels per distance—the greater the distance, the more signal loss.
The signal level may not be high enough if an HDMI cable is too long due to too much attenuation. If you need to support a longer distance, you'll need an extender, repeater, or fiber optic HDMI cable. Otherwise, you will need to find a way to use a shorter HDMI cable.
How to Extend an HDMI Cable
You can increase the range of an HDMI cable with an extender, repeater, or fiber optic HDMI cable.
HDMI repeaters are meant for shorter ranges, fiber optic HDMI cables for medium ranges, and HDMI extenders (fiber connection) for long ranges.
- Short-range extension: HDMI repeater.
- Medium-range extension: Fiber optic HDMI cable or HDMI over Ethernet extender.
- Long-range extension: HDMI over fiber extender.
HDMI Repeater
An HDMI repeater extends the connection for shorter runs by connecting two HDMI cables and amplifies the signals for better transmission.
Determining the max length when using a repeater depends on the HDMI repeater and the HDMI cable type, but I give the average ranges below. Remember that HDMI repeaters are directional, so be sure to use the device's correct input/
| Resolution | Length |
|---|---|
| 4K @ 60 Hz | 60–100 ft (18–30 m) |
| 4K @ 30 Hz | 100–130 ft (30–40 m) |
| 1080p @ 60 Hz | 135–195 ft (40–60 m) |
To be safe, assume a repeater can reach only the shorter end of those ranges.

Fiber Optic HDMI Cable
Fiber optic HDMI cables are like standard HDMI cables but made with optical fiber inside the cable and meant for farther distances up to 164 ft (50 m) for 4K @ 60 Hz.
These cables aren't meant to be used with an extender, repeater, or switch and should be used alone. They also must be installed in the correct direction, with the output/

HDMI Over Ethernet Extender
The HDMI over Ethernet extender is similar to an HDMI over fiber optic extender but uses an Ethernet cable for a shorter extension. An HDMI over Ethernet extender can extend the connection up to 130 ft (40 m) for 4K @ 60 Hz or 230 ft (70 m) for 1080p.

HDMI Over Fiber Extender
An HDMI over Fiber extender uses an optical fiber cable to transmit the data to reach a much farther distance. You could use an HDMI over Fiber extender to extend the connection up 1,000 to 3,300 ft (300 to 1000 meters) for 4K @ 60 Hz.
