Preset for this niche — adjust to your stack-up. IPC-2221 assumes still air; verify hot paths with a thermal camera.
LED Strip Driver Trace Width Calculator computes controller-board copper for multi-amp LED strip systems — free, instant and private in your browser. Lighting DIYers building amplifiers, controllers and power injection use it to skip the datasheet algebra: type your numbers, read the answer with the substituted formula shown step by step, and share an exact permalink of the calculation.
About LED Strip Driver Trace Width Calculator
LED Strip Driver Trace Width Calculator computes controller-board copper for multi-amp LED strip systems using the standard engineering relation: IPC-2221 with strip presets: 8 A common rail, 15 °C rise, 1 oz copper (or 2 oz to halve it). Worked live: 5 m of RGB at full white pulls ~8 A — the V+ feed and return need ~6 mm on 1 oz copper while each colour channel carries a third. The result recalculates on every keystroke, the worked-example panel shows your numbers substituted into the formula, and the Copy permalink button encodes the inputs in the URL so a colleague opens exactly your calculation. Everything runs client-side — nothing you type leaves your device.

Frequently asked questions
How do you calculate led strip driver trace width?+
Controller-board copper for multi-amp LED strip systems follows IPC-2221 with strip presets: 8 A common rail, 15 °C rise, 1 oz copper (or 2 oz to halve it). For example, 5 m of RGB at full white pulls ~8 A — the V+ feed and return need ~6 mm on 1 oz copper while each colour channel carries a third. The calculator applies the same relation and shows the substituted arithmetic so you can verify every step.
Why does the far end of my strip glow orange-ish?+
The strip's own copper drops volts along its length; blue/green LEDs (3+ V) dim before red (2 V), shifting white toward orange. Inject power every 2–3 m (both rails), feed from both ends, or run 24 V strips that halve the current for the same light.
One big MOSFET or one per channel?+
Per channel, always — RGB(W) dimming needs independent switches, and each only carries its colour's share. Logic-level parts (IRLZ44N class at 5 V, AO3400 class at 3.3 V) with a 100 Ω gate resistor and 10 kΩ pull-down are the standard recipe.
Is the LED Strip Driver Trace Width Calculator free and private?+
Yes — completely free with no sign-up or usage limits, and it runs entirely in your browser: the values you enter are never uploaded or stored on a server.
