Cable length meters provide an easy and accurate means of determining cable length measurements.
Our top pick is the the Klein Tools VDV501-089 VDV cable distance meter.
This Klein Tools distance meter discovers the length of a particular cable by assessing the total capacitance of the cable attached to the unit and then comparing that to a preset or user-defined capacitance per foot variable.
The Klein Tools Distance Meter ships with two alligator clip leads, an RJ-style twisted pair plug and a coaxial F-connector jack to provide input into the unit. It arrives pre-programmed for extra convenience, with nominal length constants for the following cables: RG-6 coaxial, RG-59 coaxial, RG-11 coaxial, Cat6 twisted pair, Cat3 twisted pair, and Cat5e twisted pair.
This distance meter is able to figure out if a cable run is damaged or broken, provides a 2.25" LCD display, has an auto-power off functionality as well as a low-battery indication warning system.
When in 'user mode', you'll be able to adjust the capacitance/foot constant depending on the cable you are testing.

Buyers that we spoke to say that he used it to measure connected speaker wire lengths that run into a wall.
Another buyer that we interviewed told us that it doesn't provide you individual lengths- essentially zero functionality on a single wire because it needs to have one running next to it.
This was frustrating for this particular home audio service professional.

What Are Buyers Saying?
Cable length meters enable the accurate and easy ability to perform cable length measurements. One of our favorite cable length meters is the UEi Instruments CLM100. It is equipped to measure aluminum and copper cables, as well as covering major wire-gauges. We manufacturers say that it will measure 15 to 30,000 feet, wire sizes of 26-Ga to 4/0 Ga. All you need to do to get up and running with this cable length meter is to attach the kelvin clips to both ends of the cable, make sure to choose aluminum or copper cables as well as the wire gauge in order to measure the length.
To ensure an accurate reading, the UEi Test Instruments meter calculates the temperature of the wire with its built-in temperature compensation circuit. When you purchase this cable length meter it ships with test leads, a calibration bar, a hard carrying case and a 9 V battery. Its manufacturers also say that this unit is a solid option for distributors and contractors because if its capacity to measure cable that is on a spool or that has already been installed.
There was some mixed feedback for this particular cable length meter- with one buyer telling us that it saved him a ton of time and money using it daily on his job site. In particular, it gave him great peace of mind being able to understand whether a cable would be long enough to make it run or not- and he advises that you can just subtract 3% off to ensure that it will fit.
Another option we examined was the DBPOWER SC8108 cable testing meter. Its manufacturers say that it provides accurate error location, the ability to measure cable length and detect the precise location of a short circuit or open circuit, all displayed on a large LCD backlit display. One buyer that we spoke with endorsed this cable length tester, saying its pretty simple to use and surprisingly versatile- while also saying the directions were pretty thorough. For one home service professional, being able to detect the exact cable length enables him to accurately charge his customers for the amount that he used in an installation. This, he told us, was crucial to anyone who professionally installs CAT5 cable as a professional service.
Another buyer was impressed with the wire map, saying that its near-end/4-end identification, pair-length function was excellent, especially for the price he got it. Though he says that it is not a super high-quality product, it's a functional device that saves a ton of time when a troubleshooting different wiring issues. Indeed, another reviewer that we spoke with told us that he was unimpressed by the plastic construction of the unit- saying that the plastic casing was so incredibly thin that he actually ordered a hard plastic protective case for it.
Without that protective case, he says that in his opinion the device would certainly break if dropped from a few feet. Because of this, he told us that he would not recommend this for field use, but in home work situations you could probably get by with it. Other buyers that we spoke with echo this general sentiment, saying that it is poorly constructed, not a durable and long-term option, but the price that they purchased it for was so low in comparison to the outsized functionality it provides, that overall they were happy with having bought it.
The Pyle Meters
The Pyle Meters PHCT70 network cable tester was another option we examined- its manufacturers say that they can test both unshielded (UTP) and shield (FTP) cables through its Rj45 port. As well, it has the ability to test RJ 11, coaxial cables and telephone lines by using special adapters that are not included. Its manufacturers claim that it will determine the length of individual strands in pair and length mode with about 97% accuracy. One buyer we spoke with said that it is a handy device, enabling him to troubleshoot cables in his home after he terminated them.
Overall, he was pretty impressed with the product, but he said that the interface needed some work to make it easier to use and it was a little bit too big, in his opinion. These cable tester meters enable you to assess cable continuity and sequencing- providing pair integrity analysis of cables as well as measuring the length and pair even with or without a far-end recognizer.
