If you’ve ever picked up a bottle of vape juice and seen something like 70/30 or 50/50 on the label, you’ve already encountered one of the most important factors in vaping: the PG/VG ratio. Understanding this simple number can completely change your vaping experience—affecting everything from flavor to cloud production to how your device performs.

Let’s break it down.

What Is PG/VG?

Vape juice is made up primarily of two ingredients:

VG (Vegetable Glycerin): Thicker, smoother, and responsible for producing dense vapor clouds.
PG (Propylene Glycol): Thinner, sharper, and delivers stronger flavor and a more noticeable throat hit.

The numbers on your bottle (like 70/30 or 50/50) refer to the percentage of each. A 70/30 VG/PG blend means the juice is 70% VG and 30% PG.

How the Ratio Affects Your Vape

Your ideal PG/VG ratio depends on two key things: your device and your personal preference.

50/50 Blends

Great for: Pod systems, low-wattage devices, and users transitioning from cigarettes
Feel: Balanced vapor and flavor with a moderate throat hit
Why Choose It: Delivers a more traditional, cigarette-style draw—ideal for salt nicotine or discreet vaping

70/30 Blends

Great for: Sub-ohm tanks, box mods, and mid-to-high wattage setups
Feel: Smoother inhale with larger clouds
Why Choose It: Best for freebase nicotine and cloud production. This is the go-to ratio for most flavor chasers.

Max VG

Great for: RDAs (Rebuildable Drip Atomizers) and advanced users
Feel: Ultra-smooth inhale, massive cloud output
Why Choose It: Perfect for vapers who prioritize smoothness and vapor volume over throat hit

Common Issues Related to PG/VG Mismatch

Using the wrong ratio for your device can lead to:

Dry hits – usually from using thick, high-VG juice in a small coil pod
Coughing or irritation – often caused by high PG in a high-power device
Coil burnout – thinner juice flooding coils that aren’t made for it
Weak vapor or flavor – if your device doesn’t heat thick VG efficiently

If you’re not enjoying your vape, this could be the reason.
