DC Wire Size Calculator

Features & Capabilities

WireSizer is the simplest, most intuitive DC wire size calculator for up to 60 VDC. It instantly computes the correct wire gauge based on voltage drop, current, and total circuit length, all with a touch-friendly, keyboard-free interface.

Ideal for marine electrical systems, boats, RVs, trucks, radios, solar power, and any battery-based DC setup, WireSizer validates wire size against ampacity, temperature, and installation conditions. It meets ABYC E-11 specifications (marine standard) and aligns with NEC/ISO guidelines where applicable. It runs offline, contains no ads, and includes a Materials List to record and review every wire selection.

User Reviews

Reviews praise WireSizer as an easy-to-use, DC-focused wire-sizing tool ideal for marine and solar setups. Its spinner-driven data entry, quick results, and drill-down details are frequently cited as major positives. The main drawbacks are the absence of AC calculations and higher-voltage support, leaving some users wanting broader voltage ranges, and a few comments about value for money. Overall, it’s a handy, fast tool for DC wiring with room to expand to AC and higher voltages in future updates.

Pros

Easy to use and intuitive interface.
Strong for DC wire sizing, especially for marine and solar applications.
Spinner wheels enable quick data entry and drill-down results aid understanding.
Fast, simple calculations suitable for field work on boats and in the shop.
Reported accuracy for voltage-drop calculations when checked against manual calculations.

Cons

No AC calculations or higher-voltage support; DC-only scope.
Some reviewers feel it isn’t worth the money, signaling value concerns.

Recent reviews

It’s so nice having a professional app that does its job and does not get bogged down with bells and whistles: The app only has one page! I have used WireSizer daily for years because it’s quick and gives the critical voltage drop information needed to choose correct wire size, while being entirely interactive: Spin gauge, amperage or length wheels and the results are instantly updated, making decisions easy and quick.
