HDMI and DVI Cable Length
Long HDMI and DVI cables are most commonly needed for in wall installations from the source to the TV. Some people choose to run HDMI cables up to as long as 100 feet. The general rule of thumb is, the longer the cable, the thicker it needs to be to get a signal. Cable thickness is measured by wire gauge (AWG). The lower the AWG value, the thicker the cable is.
Here are the acceptable AWGs for each length of HDMI Cable:
- 1ft-15ft HDMI Cable: 28AWG, 26AWG, 24AWG
- 20ft HDMI Cable: 26AWG, 24AWG, 22AWG
- 25ft-50ft HDMI Cable: 24AWG,22AWG
- 75ft-100ft HDMI Cable: 22AWG
It is always recommended that you test each cable out before making any runs through the wall first. That way you can be sure the signal is reaching before starting your project.
