PG and VG are the two base ingredients in every e-liquid. Understanding the difference helps you choose the right juice for your device and vaping style.
What does PG & VG mean?
PG and VG are the two base liquids that form the foundation of every e-liquid, alongside flavouring and optional nicotine.
PG — Propylene Glycol
A thin, colourless, tasteless liquid. PG carries flavour exceptionally well and produces a stronger throat hit that closely mimics the sensation of smoking. It generates less vapour than VG.
- Strong throat hit
- Excellent flavour carrier
- Thin consistency — works in all devices
- Less visible vapour cloud
VG — Vegetable Glycerin
A thick, sweet, plant-derived liquid. VG produces large, dense clouds of vapour and adds a slightly sweet taste to your e-liquid. It provides a smoother, gentler hit than PG.
- Smooth, gentle throat hit
- Large vapour cloud production
- Slightly sweet flavour
- Thick — requires sub-ohm or high-power devices
What PG/VG ratio should I choose?
Most e-liquids are sold as a blend of PG and VG. The ratio affects throat hit, vapour production, flavour intensity, and device compatibility.
The most versatile ratio. Works in any device, delivers a balanced throat hit, and produces a moderate amount of vapour. The most common ratio for nicotine salts and pod kits.
A step up in vapour production while maintaining good flavour and throat hit. Works well in most kits including MTL devices with larger coil openings.
The most popular shortfill ratio. Produces big, smooth clouds with a gentle throat hit. Ideal for sub-ohm vaping and high-power kits. Not suitable for basic pod kits.
Very high VG content for maximum cloud production. Very smooth and sweet. Requires a powerful sub-ohm device. Not compatible with smaller or low-wattage devices.
Pure VG with no PG — ideal for vapers with PG sensitivity. Produces the densest clouds and the sweetest flavour but requires a high-powered sub-ohm device and frequent coil changes.
Which ratio works with my device?
Using the wrong PG/VG ratio for your device can cause flooding, dry hits, or poor performance. Use this guide to find your match.
Pod Kits & Starter Devices
These devices have small coils with tight wicking ports. They require 50/50 e-liquid to avoid flooding and wicking issues. High-VG liquids are too thick and will not wick properly in these devices. Nicotine salts are typically a 50/50 blend and are the best choice here.
MTL (Mouth-to-Lung) Kits
MTL devices simulate the draw of a cigarette and work best with 50/50 or 60/40 blends. Some MTL kits with larger coil openings can handle 70/30, but always check your device’s specification. Higher nicotine strengths (6mg–18mg) work well here.
Sub-Ohm & DTL (Direct-to-Lung) Kits
Sub-ohm devices are designed for high-VG liquids and produce large vapour clouds. Use 70/30, 80/20, or Max VG shortfills. Lower nicotine strengths (0mg–3mg) are recommended as the direct lung inhale delivers more vapour and therefore more nicotine per puff.
Prefilled & Disposable Devices
Prefilled pod kits and disposable vapes come with e-liquid already loaded. These use a fixed blend (typically 50/50 or salt-based) selected by the manufacturer — you don’t need to worry about ratios for these devices.
Can I be sensitive to PG?
A small number of vapers experience a sensitivity or mild allergic reaction to Propylene Glycol (PG). This is more common in people who already have allergies or sensitive skin. Symptoms can include a scratchy throat, dry mouth, or skin irritation.
If you find that you’re sensitive to PG, switching to a high-VG or Max VG (100% VG) e-liquid will usually resolve the issue. Most popular shortfill brands offer 100VG options.
Signs of PG sensitivity
Dry or scratchy throat after vaping, skin rashes, headaches, or a stuffy nose may indicate PG sensitivity. If symptoms persist, consult your GP and switch to a high-VG or 100VG e-liquid.
No PG sensitivity?
You can use any ratio. Most vapers tolerate PG without issue and benefit from the improved flavour it provides.
Sensitive to PG?
Switch to 80/20, Max VG, or 100VG e-liquids. Look for brands like Nic Nic that offer a 100VG nicotine shot range.

A at-a-glance guide to choosing the right ratio for your needs.
| Ratio | Throat Hit | Cloud Size | Flavour | Best Device |
|---|---|---|---|---|
| 50/50 | Medium | Light | Strong | Pod kits, MTL, any device |
| 60/40 VG/PG | Medium | Moderate | Good | MTL & versatile kits |
| 70/30 VG/PG | Smooth | Large | Good | Sub-ohm kits |
| 80/20 VG/PG | Very smooth | Very large | Slightly sweet | High-power sub-ohm |
| Max VG (100%) | Ultra smooth | Maximum | Sweet | High-power sub-ohm only |
