## Description

**WireSizer** is a fast, offline DC wire gauge and voltage drop calculator for selecting the right copper wire size. Choose voltage, current, and total circuit length with simple touch controls—no keyboard or internet connection required. The app supports systems up to 60 VDC, currents up to 500 amps, circuit lengths up to 600 feet or 200 meters, and AWG, SAE, and metric wire sizes.

Designed for boats, RVs, cars, trucks, radios, electronics, solar, and battery-powered systems, WireSizer accounts for voltage drop, ampacity, temperature, bundling, conduit, sheathing, and insulation ratings. It includes a Materials List and calculations aligned with ABYC E-11 for DC circuits. Ad-free and suitable for professionals and DIY users.

## Review summary

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.
