The Ultimate Coil Building Guide


Most experienced vapers are always on the lookout for ways of getting more from their vape, and that’s where coil building comes in. The majority of advanced vapers will try their hand at making DIY coils at some point, and many even look on it as an art form. Building your own coils isn’t just a great way of saving money, it’s also a lot of fun and can help to improve your vaping experience. Even if you’re a complete beginner, this coil building guide will turn you into an expert in coil builds in no time.

What Do You Need To Get Started?

  • Your choice of resistance wire – nichrome, nickel, stainless steel or kanthal
  • Ceramic tipped tweezers
  • Flush cutters
  • Coiling tool or screwdriver
  • Wicking material e.g. organic cotton
  • Scissors
  • Ohm reader (optional)
  • Coil jog (optional)

Types Of RDA Coils

There are several types of coil which you can make:


Two of the most popular types of RDA coils are the macro coil and the micro coil build. Made by taking one piece of resistance wire and wrapping it around a coil jig or screwdriver, it produces a coil quickly and easily. The difference between the two is merely the coil’s inner diameter. Micro coils have a 1 to 2mm inner diameter, whereas macro coils have an inner diameter bigger than 2mm. The larger the coil’s inner diameter, the higher the resistance.


Twisted builds are another possibility, although harder to make. You need two stands of resistance wire which you twist together to make a single piece. Once the wires are twisted together, you can use it to make a micro or macro coil. Twisted wire will increase the surface area without causing too drastic a drop in resistance for better flavour.

Dual Coils

Many coil builds feature two coils, or dual coils which create more vapour than a single one. Both of the coils have to be identical in form and shape, however, so they heat properly. When using dual coils, your resistance must be precisely a half of the resistance of each coil e.g. if the dual coil is made from two 0.6 ohm coils, the build needs to be 0.3 ohms.

Ohm’s Law

Ohm’s law is an essential element of being able to make your own coils and will ensure your safety when vaping with the coils you have made. You also need to be well versed in battery safety. There are many videos on YouTube which cover the subject of coil building and they are a good place to start if you’re not sure how to begin.

Although coil building can be quite complicated, anyone can master the basic coil build as long as they get enough practice, so don’t worry if it doesn’t go according to plan the first few times. You’ll soon develop a good understanding of the process and your vaping experience will be taken to the next level.
