LED Strip Light Wire Gauge & Voltage Drop Calculator

When powering LED strips, voltage drop is commonly explained by insufficient copper quality or thickness in an LED strip's PCB substrate.

But, in many cases, it can also be caused by the wires that lead up to or connect between LED strip segments. This is why it is very important to be aware of the wire gauge (thickness) used in the wiring for LED strips.

Wire Gauge and Voltage Drop Calculator

Use the following calculator to determine if the wire gauge is sufficient for your LED strip wires. The calculator also provides an estimated voltage drop across the wires. Keep in mind the results do not include the voltage drop of the LED strip itself and only includes the voltage drop in the wires.
