This is the question that tips most experienced vapers into building their own coils. The short version: it’s significantly cheaper than buying pre-built replacements, once you factor in how many builds you get from a single spool.
A typical 10 metre spool of 26g Ni80 round wire gives you roughly 15 to 20 single-coil builds depending on your coil diameter and wrap count. Spools at this length are available from around £3 to £5 at Legion of Vapers. That works out to somewhere between 15p and 33p per coil build.
Compare that to pre-built coils, which typically cost £1.50 to £3.50 per coil depending on the brand and compatibility. Even accounting for vape cotton costs (a pack of Japanese organic cotton usually covers dozens of re-wicks), the savings are substantial over time.
The main up-front cost is a rebuildable tank – RDA, RTA or RDTA. After that, your running costs drop considerably. For a fuller breakdown of how building compares to other vaping costs, see our can vaping save you money guide.
Kanthal is the most beginner-friendly coil wire available, and there’s a good reason most builders start here. It’s stiff enough to hold its shape when you’re wrapping a coil, which makes it much easier to work with than softer materials. It also has a wide range of compatible gauges, so you can experiment without committing to a specific build style.
The trade-off is ramp-up time. Kanthal heats more slowly than Ni80 or stainless steel at equivalent gauges, which means a slightly less instant response when you fire your mod. For most vapers, this isn’t a deal-breaker, especially at the learning stage. Common gauges for single-coil builds range from 24g to 28g, with 26g being a reliable starting point for a sub-ohm RDA build.
Kanthal is wattage-mode only. It can’t be used in temperature control. If that’s where you want to end up, Kanthal is still worth starting with for practice builds before moving to SS316L. Head over to our how to build vape coils guide if you’re just getting started.
Note: Kanthal (KA1) is nickel-free, making it the safest default choice for anyone with a nickel sensitivity.
Nichrome wire is the natural step up from Kanthal for wattage-mode builders. It ramps up noticeably faster, which gives a more responsive feel when you fire, and most builders find it produces cleaner, more pronounced flavour than Kanthal at the same resistance.
Ni80 (80% nickel, 20% chromium) is the most common variety and works well across a wide gauge range. Ni90 runs slightly hotter and a little faster again, but the difference between the two is subtle in practice. Both are popular choices for single and dual-coil RDA builds.
Nickel allergy warning: Ni80 and Ni90 both have a high nickel content. Anyone with a confirmed nickel allergy or sensitivity should avoid these materials. See the dedicated allergy section below before purchasing.
SS316L is the most versatile wire on this list. It works in both wattage mode and temperature control mode, which makes it the go-to choice for builders who want one wire to cover multiple setups or mods.
Ramp-up time is faster than Kanthal and broadly comparable to Ni80 in most builds. Flavour is clean and neutral, which suits vapers who don’t want the wire itself affecting how their e-liquid tastes. It’s also harder than Ni80, which means it holds its coil shape well and is a good option if you’re bending more complex configurations.
One note on dry burns: keep the wattage low when dry-burning SS316L coils to clean them. High-wattage dry burns can cause the wire to discolour heavily and potentially affect coil performance. For TC vaping, check our guide on what is temperature control vaping to make sure your mod supports SS316L’s TCR values.
Nickel allergy warning: SS316L contains a small amount of nickel. Vapers with nickel sensitivities should check material composition before use.
Ni200 is a temperature control-only wire. Do not use it in wattage mode. The resistance is so low at operating temperatures that firing it in wattage mode without proper TC protection can result in a runaway heating situation, and the wire itself can get damaged very quickly.
In TC mode with a compatible mod, Ni200 provides excellent temperature consistency. It’s very soft and malleable compared to other wire types, which makes it trickier to wrap cleanly, especially on tight dual-post decks. Most builders who start with Ni200 find SS316L easier to handle for TC builds while delivering similar temperature stability.
Nickel allergy warning: Ni200 is almost pure nickel. Anyone with any nickel sensitivity should not use this wire.
Titanium wire is a TC-only option that has largely been overtaken by SS316L in everyday use. It’s lightweight and corrosion resistant, but handling it requires a reliable TC mod and good temperature awareness. At temperatures above 648°C, titanium oxide can form on the wire surface, which is why it’s firmly in the experienced-builders-only category. If your TC mod is well-calibrated and you know your setup, titanium wire performs well. If you’re not confident in your mod’s TC accuracy, stick with SS316L.
Round wire is the standard format for coil building, and it’s where every builder should start. It’s easy to source, straightforward to wrap and compatible with every rebuildable setup from a simple single-coil RDA to a tight-deck RTA. All of the wire types above are available in round format.
A single round wire coil is also the easiest to troubleshoot. If something isn’t right with your build, there are fewer variables to account for than with more complex formats.
Flat and ribbon wire have a rectangular cross-section rather than a circular one. That wider profile increases the surface area in contact with your wick, which generally translates to better flavour – more of the coil surface is heating your e-liquid evenly.
In an open-deck RDA, flat wire is relatively easy to work with. On a tighter RTA deck, it can be frustrating to wrap neatly without kinking. Vandy Vape flat wire in particular wicks more evenly in snug RTA builds than some round wire of equivalent gauge, but you do need to take your time with the wraps. If you’re building for an RTA, practise the coil shape on a mandrel before installing it.
Fused Clapton wire wraps one or more thinner wires tightly around a core strand (or strands), creating a textured surface that dramatically increases the surface area compared to a simple round wire at the same gauge.
The result is more intense flavour and denser vapour production. The trade-off is slower ramp-up time, because there’s more wire mass to heat. Complex builds like Claptons also require more wicking care than round wire coils – if the wick doesn’t sit right in all those outer wraps, you’ll get dry hits.
These formats work best in open-deck RDAs where you have room to work with and wick properly. Drop one into a restricted RTA deck and you’re making life harder than it needs to be. See our RDA, RTA and RDTA tanks explained guide for a breakdown of which setup suits which build style.
If you just want a quick steer on which wire suits your build style, use this comparison:
| Wire | Best For | Temperature Control |
|---|---|---|
| Kanthal | Beginners | No TC |
| Ni80 | Flavour | No TC |
| Ni90 | Faster ramp-up | No TC |
| SS316L | Versatility | TC compatible |
| Ni200 | Dedicated TC builds | TC only |
| Titanium | Advanced TC builders | TC only |

Kanthal (KA1) is the best starting point. It holds its shape during wrapping, which makes building easier, and it’s widely available in beginner-friendly gauges like 26g and 28g. It only works in wattage mode, but that covers the vast majority of vaping setups.
Both work in wattage mode, but Ni80 ramps up faster and generally produces cleaner, more pronounced flavour. Kanthal is more forgiving to work with due to its stiffness. Most builders start on Kanthal and move to Ni80 once they’re comfortable with the basics.
Yes. SS316L is the most practical wire for TC builds because it also works in wattage mode, so you can use the same wire regardless of which mode you prefer. Make sure your mod supports SS316L’s TCR value – most modern TC mods do.
For a sub-ohm open-lung RDA build, 24g to 26g is a reliable starting range in Ni80 or SS316L. This gives you a manageable resistance around 0.2 to 0.4 ohms for a typical 6-wrap coil. For a restricted lung single coil, move up to 26g or 28g.
Flat wire has a rectangular cross-section that increases the surface area in contact with your wick compared to round wire at the same gauge. More surface area in contact with the e-liquid generally means improved flavour clarity. The difference is noticeable, though the build is slightly trickier than standard round wire.
A 10 metre spool of single-strand round wire at 26g gives you roughly 15 to 20 single-coil builds. Larger spools go further. How often you need to rebuild depends on your e-liquid, how frequently you vape and whether you re-wick or do full rebuilds.
Start with round wire. Clapton builds require more patience to wick correctly, and the slower ramp-up time can be frustrating if you’re used to the responsiveness of a simple round coil. Once you’re comfortable with single-strand builds, Clapton wire is a genuine upgrade for flavour and vapour density.
No. Ni200 nickel wire must only be used in temperature control mode on a compatible mod. Using it in wattage mode is unsafe and can damage the wire and potentially your device.
Ni80 is 80% nickel and 20% chromium. Ni90 is 90% nickel with a lower chromium content. Ni90 runs slightly hotter and ramps up a fraction faster, but the practical difference in day-to-day use is subtle. Both are solid choices for wattage builds. Both carry the same nickel allergy risk.
Kanthal or Ni80 in higher gauges (28g to 32g) are the most common choices for mouth-to-lung builds. You’re targeting higher resistance – typically 1.0 ohm and above – so thinner wire is the right direction. Keep builds simple for MTL: a tight, small-diameter coil in round wire is perfectly suited to the style.
The terms are often used interchangeably, but ribbon wire is typically thinner in cross-section while flat wire is slightly wider and more square in profile. Both offer more surface area than round wire. If your deck is tight, ribbon wire is often easier to work with. Flat wire gives a marginal surface area advantage in more open decks.
Titanium wire is available but has largely been replaced by SS316L for TC builds. It performs well in temperature control with a reliable mod, but the handling considerations at extreme temperatures make it a less practical everyday option. SS316L covers the same use case with fewer complications for most builders.
