What the Wire Size Calculator does
Use the free Wire Size Calculator to pick a wire gauge from load amps, run length, voltage, and a maximum voltage-drop percent.
That is the whole scope of the page. It sits in Home & Trade Calculators, the group for home, workshop, electrical & property. The Wire Size Calculator only does the job in that first sentence.
Wire Size Calculator runs in your browser. The file or the figures stay on your device, and the free plan does not ask you to create an account.
When a Wire Size Calculator is the right page
Use it when you are about to buy material, size a wire, or price a job and you have the measurements.
Open it when you need to pick a wire gauge from load amps, run length, voltage, and a maximum voltage-drop percent. If you need a different output, pick the tool whose description names that output.
How to use the Wire Size Calculator
Enter length, area, or load in the units on the label. A foot typed into a metre box will order the wrong amount.
Run it once with the values you have. The result should line up with this promise: Pick a wire gauge from load amps, run length, voltage, and a maximum voltage-drop percent. Change one field if you want a second case, and keep the other fields the same so you can see what moved.
How to read the result
Round up for material you cannot buy in fractions, and keep a waste margin the page does not invent for you.
Keep the units, the dates, and the file type that the form showed. A number from the Wire Size Calculator is ready to copy only after you have checked it against the labels on this page.
What the Wire Size Calculator leaves out
Codes, span tables, and the product you buy can require a stricter number than this estimate. This page does not replace a licensed tradesperson where the work can injure someone.
Anything the description does not mention is outside this tool. Use the result as the estimate or the file this page promised, then check the source that actually applies to your bank, school, client, or project.
The next tool
