PG vs VG | A Comparison Guide to E-Liquid Ratios

PG and VG are both commonly used e-liquid base ingredients, but they provide different vaping characteristics. PG is thinner and generally provides stronger flavor and throat sensation, while VG is thicker and generally produces more vapor with a smoother feel. The best PG/VG ratio depends on your device, coil, vaping style, and personal preference.

If you’ve ever looked closely at an e-liquid bottle, you’ve probably noticed two letters appearing again and again: PG and VG. These two ingredients form the base of most e-liquids, and the ratio between them can significantly affect how your vape feels and performs.

So, which is better: PG or VG?

The answer depends on what you want from your vaping experience. PG (propylene glycol) is thinner and generally provides a more pronounced flavor and throat sensation, while VG (vegetable glycerin) is thicker and generally produces more vapor with a smoother inhale. For many vapers, a balanced 50/50 PG/VG blend provides a practical middle ground.

Your device and coil also matter. A liquid that works well in a compact pod may not be the best choice for a higher-powered device.

In this guide, I’ll break down PG vs VG, common ratios, flavor, vapor production, throat hit, pod compatibility, nicotine salts, and how to choose the right blend for your setup.

What Are PG and VG?

PG and VG are liquids used as the primary base ingredients in many vape liquids. They carry nicotine and flavor concentrates and determine much of the liquid’s physical characteristics and vaping behavior.

Although both can be used in the same e-liquid, they behave quite differently when heated and vaporized.

What Is PG?

PG stands for propylene glycol.

It is a relatively thin, low-viscosity liquid commonly used in e-liquid formulations. In vaping, PG is valued for its ability to carry flavor effectively and provide a more noticeable sensation in the throat.
A higher-PG e-liquid will generally feel:

• Thinner
• More pronounced in flavor
• More noticeable in the throat
• Less cloud-producing than a high-VG blend

Because of its thinner consistency, PG-focused liquids are commonly associated with mouth-to-lung (MTL) vaping and devices with smaller coils or tighter airflow.

PG isn’t necessarily “better” than VG. Its advantages simply suit a particular style of vaping.

What Is VG?

VG stands for vegetable glycerin, also known as glycerol.

It is considerably thicker than PG and is known for producing larger amounts of visible vapor when used in suitable vaping devices.

A higher-VG e-liquid will generally provide:

• Thicker liquid
• More visible vapor
• A smoother-feeling inhale
• Less pronounced throat sensation than a similar PG-heavy blend

VG-heavy liquids are commonly associated with RDL (restricted direct-to-lung) and DL (direct-to-lung) vaping, where the device and coil are designed to handle thicker e-liquid and higher vapor production.

The important thing to remember is that PG and VG aren’t competitors where one always wins. They’re different ingredients with different characteristics, and many e-liquids combine them to achieve a specific balance.

PG vs VG: What’s the Difference?

The simplest way to understand PG vs VG is to look at what each ingredient contributes to an e-liquid.

Feature	PG	VG
Consistency	Thinner	Thicker
Flavor perception	Generally more pronounced	Generally softer
Throat sensation	More noticeable	Smoother
Vapor production	Lower	Higher
Wicking	Generally easier for many coils	Requires suitable wicking
Common use	MTL-style vaping	Higher-vapor setups
Typical preference	Flavor and throat sensation	Vapor and smoothness

PG is generally better suited to users who want:

• Pronounced flavor
• More throat sensation
• A thinner e-liquid
• A tighter MTL draw
• Moderate vapor production

VG is generally better suited to users who want:

• More visible vapor
• A smoother inhale
• Thicker e-liquid
• RDL or DL vaping
• Higher-vapor performance

However, the PG/VG ratio is often more important than choosing one ingredient by itself. Most vapers don’t use pure PG or pure VG. Instead, they choose a blend that matches their device and preferences.

PG vs VG: Which Is Better?

There is no universal winner.

PG is generally the better choice for flavor-focused, MTL-style vaping, while VG is generally the better choice for users who prioritize vapor production and a smoother inhale.

For example, someone using a compact pod system with a relatively tight draw may prefer a balanced or PG-focused e-liquid. Someone using a more powerful device designed for substantial vapor production may prefer a higher-VG blend.

Your personal preference also matters.

If you enjoy a stronger throat sensation and don’t need large clouds, increasing the PG proportion may make sense. If you prefer a smoother experience with denser vapor, increasing the VG proportion may be more appropriate.

For users who want a balance between the two, 50/50 PG/VG is one of the most practical starting points.

The best approach is therefore:

Choose the e-liquid ratio based on your device first, then fine-tune it according to your preferred flavor, throat sensation, and vapor production.

What Are the Common PG/VG Ratios?

E-liquids are available in many different PG/VG combinations. The ratio tells you how much of each base is present in the liquid.

For example, a 50/50 PG/VG e-liquid contains approximately equal proportions of PG and VG in its base.

50/50 PG/VG

A 50/50 blend offers a relatively balanced experience. It’s often chosen for:

• Pod systems
• MTL vaping
• Balanced flavor and vapor
• Users who don’t want extremely thick e-liquid

For many beginners, 50/50 is an easy starting point because it doesn’t heavily favor either PG or VG.

60/40 VG/PG

A 60/40 VG/PG blend shifts the balance toward VG. Compared with 50/50, it generally provides:

• More vapor
• A smoother feel
• Slightly thicker e-liquid

It can be useful for devices capable of handling a moderately thicker liquid.

70/30 VG/PG

A 70/30 VG/PG blend is strongly VG-focused.

These blends are commonly associated with devices designed for higher vapor production, such as suitable RDL or DL setups.

The increased VG content can produce thicker vapor, but the liquid is also considerably more viscous than a 50/50 blend.

80/20 VG/PG

An 80/20 VG/PG blend is even more VG-heavy.

It is generally intended for devices and coils specifically designed to handle thicker e-liquid. It isn’t automatically a better option simply because it contains more VG. 100% VG

Pure VG is possible, but it is not a practical general-purpose choice for every vaping setup.

Its very high viscosity can create wicking challenges for devices that aren’t designed to handle it. Always check your device and coil manufacturer’s recommendations before using an unusually thick e-liquid.

Which PG/VG Ratio Is Best for Pod Systems?

For many pod systems, 50/50 PG/VG is a practical starting point, particularly when the device is designed for MTL vaping.

Why?

A balanced blend is relatively thin, allowing many smaller pod coils to wick it effectively. It can also provide a useful balance between flavor, vapor production, and throat sensation.

Why 50/50 Works Well for Many Pods

A typical 50/50 e-liquid can provide:

• Good flavor
• Moderate vapor
• A relatively smooth but noticeable inhale
• Suitable viscosity for many smaller coils

This makes it particularly popular among users who prefer a cigarette-like MTL experience.

Can You Use High-VG E-Liquid in a Pod?

It depends on the specific pod and coil.

Some modern pod systems are designed to accommodate thicker e-liquids, while others perform better with thinner formulations.

Using an e-liquid that is too thick for a particular coil can lead to poor wicking and inconsistent performance.

For that reason, always check the manufacturer’s recommended e-liquid range before choosing a PG/VG ratio.

Which PG/VG Ratio Is Best for Vape Mods?

Higher-powered devices generally provide more flexibility when it comes to e-liquid viscosity.

Many setups designed for RDL or DL vaping work well with higher-VG blends such as 70/30 VG/PG, although the appropriate ratio depends on the specific tank, coil, and power range.

Higher-VG liquids can help support:

• Greater vapor production
• Smoother inhalation
• Larger airflow configurations
• Higher-power vaping

But more VG isn’t automatically better.

A high-VG liquid in a coil that can’t wick it efficiently may produce poor results. You could experience inconsistent vapor production, dry hits, or reduced coil performance.

The coil manufacturer’s specifications should always take priority over a general rule about PG/VG ratios.

PG vs VG for Flavor

If flavor is your highest priority, PG often has an advantage.

PG generally carries flavor concentrates effectively and tends to produce a more pronounced flavor experience. This is one reason PG-containing blends are popular among MTL users who want a strong and defined flavor profile.

VG can also produce excellent flavor, but its thicker nature and smoother characteristics can make the overall experience feel different.

However, PG/VG ratio isn’t the only factor that determines flavor.

Flavor quality can also depend on:

• E-liquid formulation
• Flavor concentrates
• Coil design
• Coil condition
• Wattage
• Airflow
• Temperature
• Device performance

So it would be inaccurate to say that “PG always tastes better.” A high-quality VG-heavy e-liquid used in a suitable device can deliver excellent flavor.

Bottom line: If you want a more pronounced flavor experience, a higher-PG blend may be worth considering.

PG vs VG for Vapor Production

When it comes to visible vapor, VG generally wins.

VG is thicker and tends to produce considerably more vapor when vaporized in an appropriate device. This is why higher-VG e-liquids are commonly associated with RDL and DL vaping.

PG, by comparison, generally produces less visible vapor.

However, vapor production isn’t controlled by PG/VG ratio alone. Your:

• Coil
• Wattage
• Airflow
• Device design
• Puff duration

can all significantly affect how much vapor you produce.

So if you’re looking for bigger clouds, choosing a higher-VG e-liquid is only part of the equation. You also need a device and coil designed to support that type of vaping.

Best for vapor production: Higher VG

PG vs VG for Throat Hit

The sensation you feel in your throat during an inhale is another major difference between PG and VG.

PG generally provides a more noticeable throat sensation, while VG tends to feel smoother.

This can be particularly important for users who prefer an MTL vaping experience and want a sensation that more closely resembles the feel of smoking.
Nicotine can also influence throat sensation. The type and strength of nicotine, as well as the overall e-liquid formulation, can change how an e-liquid feels.
Therefore, increasing PG isn’t the only way to change throat sensation—but PG/VG ratio is an important factor.

For a stronger throat sensation: Higher PG is generally preferable.

For a smoother inhale: Higher VG is generally preferable.

PG vs VG for Nicotine Salts

Nicotine salt e-liquids are commonly used in pod systems, and their PG/VG ratio can significantly affect how they perform.

Many nicotine salt formulations use balanced or relatively PG-forward ratios, particularly when designed for compact MTL devices.

A thinner liquid can work well with smaller pod coils that aren’t designed for very thick e-liquid.

However, there is no universal PG/VG ratio for every nicotine salt product.

Some manufacturers formulate salt nicotine liquids specifically for different types of devices, so the product specifications should always be checked before use. when choosing a nicotine salt e-liquid, consider:

• Your pod or coil
• Recommended PG/VG ratio
• Nicotine strength
• Desired throat sensation
• Preferred vapor production

The right combination should provide consistent wicking and a comfortable vaping experience.

Can PG or VG Affect Coil Performance?

Yes. E-liquid viscosity can influence how effectively a coil wicks and vaporizes the liquid.

PG is thinner than VG, so higher-PG blends are generally easier for many small coils to wick.

VG is considerably thicker. High-VG liquids therefore work best in devices and coils designed to handle their viscosity.

Using a liquid that is too thick for a particular coil can contribute to:

• Poor wicking
• Inconsistent vapor production
• Dry or unpleasant hits
• Reduced coil performance

On the other hand, choosing an appropriate ratio for the device can help maintain more consistent performance.

This is why the PG/VG ratio should never be selected based solely on flavor or cloud preference.

Device compatibility comes first!

How to Choose the Right PG/VG Ratio

Choosing the right ratio becomes much easier when you work through a few simple questions.

1. What Device Are You Using?: A compact pod with a small MTL coil may have very different e-liquid requirements from a powerful tank designed for high vapor production.

2. What Type of Coil Do You Have?: The manufacturer’s recommended e-liquid range can help you avoid choosing a liquid that’s too thick or too thin for your setup.

3. How Do You Vape?: If you prefer a tight MTL draw, a balanced or more PG-focused liquid may suit you. If you prefer RDL or DL vaping, a higher-VG liquid may be more appropriate when supported by your device.

4. What Do You Prioritize?: Choose more PG if you want:

• Stronger flavor
• More throat sensation
• Thinner liquid
• Choose more VG if you want:
• More vapor
• A smoother inhale
• Thicker liquid

5. Want a Balance?: A 50/50 PG/VG blend is often a sensible starting point for users who want a balance between flavor, vapor, and throat sensation, provided their device is designed for it.
The simplest decision process is:

Device → Coil → Inhale style → Flavor preference → Vapor preference → PG/VG ratio
That approach is much more reliable than choosing an e-liquid based on PG/VG numbers alone.
