This wire size calculator will calculate the appropriate wire gauge for a circuit based on amps, voltage, distance, and load. This website provides a wire size calculator, voltage drop calculator, wire ampacity charts and more.

Enter the source voltage, allowable voltage, and current in the wire size calculator and the tool will calculate the gauge of the wire. A wire size calculator assists to select the correct size of electrical wire based on amps, voltage, distance, and load.

Enter the voltage in volts. Input the load in amperes. Specify the distance the wire will cover in feet. Click the “Calculate” button to obtain the recommended wire size in American Wire Gauge (AWG).

The wire size calculator will help you select the correct gauge of electrical wire for your next electrical project, such as installing a pump in your garden pond, wiring up your tiny house, or getting power to your shed.

Calculate the minimum size of a wire or conductor needed for a circuit, or calculate the dimensions of the wire, including the diameter, cross-sectional area, and resistance given its gauge.
