If we had one complaint about the DIY scene, it's that people don't measure enough. We'd change the habit of mixing by feel. Even experienced mixers benefit from a consistent target ratio. Write down your recipe, note the VG/PG split, and stick to it until you intentionally change it.

And that's exactly what the Windbar E-liquid Mix Calculator is for. You punch in your target ratio, nicotine base strength, and bottle size—it tells you exactly how many ml of each ingredient to add. No guesswork, no wasted bottles.

Before you start mixing, double-check your nicotine base. If it's 100mg/ml, you'll need far less than a 50mg base. The calculator handles that, but it's worth understanding what you're working with. And always work in a well-ventilated area, wear gloves if you're handling high-strength nicotine, and keep everything away from kids and pets.

One more thing: if you're buying commercial e-liquid, the ratio is printed on the bottle. Pay attention to it, especially if you're switching devices. A high-VG juice in a low-power pod will be slow to wick and might taste burnt.
