VG Ratio for 0.15 to 0.4 Ohm Sub-Ohm Coils: What Makers Print

Overview

The VG ratio for sub ohm coils of 0.15 to 0.3 ohm is listed by Vaporesso as 40/60 to 30/70 PG/VG, and for a 0.4 ohm coil as 50/50 to 40/60 PG/VG. That is one maker’s published guidance, not a universal rule, and other makers can differ.

This page sets out those ranges as the maker prints them. We do not invent a best ratio. Your coil’s packaging or manual is the final reference, and this guide is for adults aged 21 and over. If you want the wider picture first, our PG/VG ratio explained guide is the place to start.

VG ratio for sub ohm coils by resistance

The table below uses Vaporesso’s published GTX coil guidance. Ratios come from its liquid-choice guide, and wattage ranges come from the specifications on its GTX coil page. We chose this maker because it publishes both on its own pages.

Coil resistance	Vaping style	Maker-listed PG/VG range	Maker-listed wattage
0.15 ohm	Direct-to-lung	40/60 to 30/70	60-75 W
0.2 ohm	Direct-to-lung	40/60 to 30/70	45-60 W
0.3 ohm	Direct-to-lung	40/60 to 30/70	32-45 W
0.4 ohm	Direct-to-lung	50/50 to 40/60	26-32 W

The maker’s liquid guide groups 0.15 to 0.3 ohm in a single row, so each of those three coils carries the same printed range. The 0.4 ohm coil moves to a thicker-PG range, which means the ratio changes by coil resistance and not by one fixed number.

Ratios are written PG first, then VG. So 40/60 is 40% PG and 60% VG, and 30/70 is 30% PG and 70% VG.

What VG ratio for a 0.2 ohm coil?

For the Vaporesso GTX 0.2 ohm coil, the maker lists 40/60 to 30/70 PG/VG, which is 60% to 70% VG. Other coils rated 0.2 ohm from other makers may print a different range, so read the pack for the coil you own.

Reading a PG/VG ratio

A PG/VG ratio shows how much of the liquid base is propylene glycol and how much is vegetable glycerine. The two numbers add up to 100, so you only need one to find the other. Bottles may print the ratio on the front or near the ingredients.

The conversions are simple arithmetic. In a 60 ml bottle, a 30/70 base is 18 ml PG and 42 ml VG. A 40/60 base is 24 ml PG and 36 ml VG. A 50/50 base is 30 ml of each. These figures ignore flavouring and nicotine, so they show the base proportions only, not an exact recipe.

• 40/60 PG/VG means 40% PG and 60% VG.
• 30/70 PG/VG means 30% PG and 70% VG.
• 50/50 PG/VG means equal parts.

Some bottles print only the VG percentage, or write “70VG” on the label. That is the same information in shorter form. If you cannot find a ratio on the pack, ask the seller before buying, because without it you cannot compare the liquid against a coil’s printed range.

The ratio is a voluntary extra on many bottles, so where it is printed varies by brand.

Why the ranges differ

Look at the table again. The three lowest-resistance coils share one range, while the 0.4 ohm coil has a lower VG range. Vaporesso’s liquid guide says to match the PG/VG ratio to your coil, and it describes higher-VG juice as suited to sub-ohm tanks.

The wattage column shows another difference. The 0.15 ohm coil is listed at 60-75 W and the 0.4 ohm coil at 26-32 W, so these coils are built for quite different power levels. We do not claim that wattage causes the ratio difference, because the maker does not say so on the pages we read. The point is only that resistance, wattage and liquid range are listed together by the maker, so you should read them together.

Our guide to coil wattage that is too high covers what to do if you run a coil outside its listed range. For a wider look at lifespan, see how long vape coils last.

The coil’s resistance explains the style. Vaporesso labels these as direct-to-lung coils, meaning you draw the vapour straight into the lungs rather than into the mouth first. Our MTL vs DTL explained guide covers the difference.

Ratio, wicking and flavour trade-offs

Every ratio is a trade-off, and the maker describes it in plain terms. Vaporesso says VG gives denser vapour and a smoother hit, while PG carries flavour well and gives a stronger throat hit with less vapour. That is the whole of the sourced trade-off, so we stay with it.

• Higher VG: denser vapour and a smoother hit, according to the maker.
• Higher PG: sharper flavour, a stronger throat hit and less vapour, according to the maker.
• Match the range to the coil printed on the pack, not to a general preference.

Thicker liquid and wicking

Vaporesso notes that tight mouth-to-lung coils wick thin liquids easily but can struggle with very thick, high-VG juice. That statement is about tight MTL coils, not the sub-ohm coils in the table. It is a reminder that thickness and coil design interact, so a liquid that suits one coil may not suit another.

Does a higher VG ratio mean more vapour?

According to the maker, yes: VG produces denser vapour. Whether that suits you depends on the range printed for your coil. We do not claim a higher ratio is better, because a ratio outside the printed range is not what the maker recommends.

We have not found a maker source on leaking and ratio, so we make no claim about it here.

Checking the coil and the manual

Start with the packaging. Makers print resistance, and often a wattage range, on the coil or its box. Some also print a liquid range or point you to the manual or the support page.

How to read the coil marking

Look for a figure followed by the ohm symbol, such as 0.2. That is the coil resistance. Then look for a wattage range, usually written as two numbers with a W. If a liquid range is printed, compare it with your bottle’s PG/VG ratio. If none is printed, check the device maker’s manual or support page, which is the reference for your own coil.

The wattage and resistance data we used came from the maker’s product page, which also showed small differences between its table and its image captions for some coils. We used the table figures only. If you see two figures for the same coil, trust the one on the coil’s own box and manual.

Prime a new coil before use, as the maker advises in its liquid guide, and keep the pack so you can check the resistance later. Our dry hit on a new coil guide explains why priming matters.

Matching liquid to your coil

Once you know the printed range for your coil, finding a matching bottle is a matter of reading ratios. Look at the ratio on the front or the ingredients list and see whether it falls inside the range. A 40/60 bottle sits at the highest-VG end of the 0.4 ohm range and the lowest-VG end of the 0.15 to 0.3 ohm range, for example.

That overlap is arithmetic from the table, not extra maker guidance. At 40/60 the two ranges meet, but check that your own coil prints that range before you rely on it.

• Find your coil’s resistance and printed liquid range.
• Read the PG/VG ratio on the bottle.
• Confirm the ratio falls inside the range.
• Check the label for the required items before you open the bottle.

What this page does not cover

This page reports one maker’s printed guidance. It does not cover every brand of sub-ohm coil, and it does not tell you the best ratio for your device. We have not tested coils ourselves for this guide.

It also covers only coils from 0.15 to 0.4 ohm. Higher-resistance coils, pod systems and mouth-to-lung devices follow different rules. For those, see our MTL pod kit guide and the vape coil resistance guide.

If a coil you own prints a different range from the one in our table, follow your coil. Makers can change coil designs and published guidance, so the pack and manual are the current reference.

Finally, we make no health claims. Vaping delivers nicotine, and it is for adults aged 21 and over.

The source for the ratios is Vaporesso’s guide to choosing the right e-liquid, and the wattage ranges come from the Vaporesso GTX coils product page.
