Finding the Right E‑liquid Ratio for Your Vape Device

Bottles of VG and PG

At, we want to give you everything you need to start vaping and help you get the most you can out of your vape juices. That’s why we don’t just  sell e-liquids, but also provide loads of helpful eliquid insights to make sure you become a vaping expert!

This time around, we’re going to talk you through how to make sure you’re using the right e-liquid ratio. For those of you who hate maths, talking about ratios can seem pretty frightening, but we've made it simple!

What is an e-liquid ratio? 

E-liquids are essentially a nicotine-based liquid vapour substitute for traditional cigarette smoking. Broken down simply, they’re just water, flavouring, nicotine, and two liquids known as PG (Propylene Glycol) and VG (Vegetable Glycerin). That super simple formulation without any hidden nasties found in tobacco is why so many people switch to vaping from smoking!

It’s the balance of VG to PG that makes up the ratio that people refer to while discussing e-liquid ratios. Frequently used in foods and other everyday items,  vaping PG and VG change the density of the vape clouds, the intensity of the vape flavour, and how harsh the throat hit is. That’s why they’re so important!

What is Propylene Glycol?

So, you know they’re liquids, but what actually are these two compounds, and why are they in your e-liquid? First up, we’ve got propylene glycol (PG), a well-known food additive that’s recognised as generally safe by the FDA.

Propylene glycol is an odourless, colourless liquid with a slightly sweet hint to it. When used in e-liquids, it’s main role is to provide a harsher throat hit (like smokers are used to) and to make the vape flavour more pronounced!

What is Vegetable Glycerin?

Our second compound is vegetable glycerin (VG), another odourless and colourless liquid. It’s frequently used in FDA-approved medicines due to its antiviral properties, while also being used in a large number of food items as a sweetener. 

Vegetable glycerin is thicker than propylene glycol, which is why it also leads to thicker liquid vapour clouds when you exhale. It’s also associated with a generally smoother inhale, which is important for specific styles of vaping.

What e-liquid PG/VG ratio is right?

Now you know the basics about PG and VG, you need to figure out what ratio between the two is right for you before you buy vape juices! We’re going to break it down into three broad categories, just to make sure things are kept as simple as possible. 

1. High VG e-liquids

Remember, high levels of VG will lead to thicker, more impressive clouds, as well as a smoother vape from you e-cig liquid. If you want some seriously rich flavour or massive liquid vapour, then you should always go for high VG.

High VG e-liquids are always better in more powerful devices like sub-ohm kits because of the thicker consistency of the vaping liquid. Thanks to the reduced throat hit, you can inhale the liquid vapour direct-to-lung and really hit some massive clouds!

2. High PG e-liquids

High PG e-liquids were once quite common, but you don’t see them around as often anymore. The higher the PG the higher the throat hit and the intensity of the vape flavour, but it also means that way less vapour is produced. 

These will always work best in mouth-to-lung vape devices, both because of the thinner consistency and because the increased throat hit makes direct-to-lung vaping much more difficult. If you’re obsessed with vape flavours, these are a good bet.

3. 50/50 e-liquids

This middle ground option actually has more in common with high PG e-liquids than it does VG. 50/50 e-liquids have a slightly smoother throat hit, but they still pack a flavourful punch and work best in mouth-to-lung devices.

This would normally be your go-to if you're looking for a more traditional smoking experience, but still want to experiment with all the fun vape flavours available when vaping liquid vapour.

Now you know the score with PG/VG ratios, the best way to learn is always to trial out a few different options, and see what you prefer. Nic salts, shortfills, 50/50 vape juices; there are so many mouthwatering e-liquids types and flavours fout there for you to try!
