Use this 120ml longfill mixing table to quickly calculate how much VG, PG, and nicotine you need to create your final e-liquid.
This guide is based on a standard 120ml longfill with 10ml of flavour concentrate. Both the flavour and nicotine shots are calculated as PG-based, which affects your final VG/PG ratio.
By following this table, you can easily mix your own e-liquid, control your nicotine strength, and reduce your overall cost compared to pre-made liquids.
Mixing your own 120ml e-liquid gives you full control over flavour strength, nicotine level, and VG/PG ratio.
Most vapers in Ireland choose between 50/50 and 70/30 ratios depending on their device and preference. Lower VG ratios provide stronger flavour and throat hit, while higher VG ratios produce smoother vapour and larger clouds.
For higher nicotine strengths, it’s important to remember that achieving an exact VG/PG ratio may not always be possible, as both flavour concentrate and nicotine shots typically contain PG.

| Final Nicotine Strength | 18mg Nicotine Shots Needed | VG to Add | PG to Add |
|---|---|---|---|
| 1.5mg | 1 x 10ml shot | 60ml | 40ml |
| 3mg | 2 x 10ml shots | 60ml | 30ml |
| 4.5mg | 3 x 10ml shots | 60ml | 20ml |
| 6mg | 4 x 10ml shots | 60ml | 10ml |

| Final Nicotine Strength | 18mg Nicotine Shots Needed | VG to Add | PG to Add | Note |
|---|---|---|---|---|
| 1.5mg | 1 x 10ml shot | 84ml | 16ml | Exact 70/30 ratio |
| 3mg | 2 x 10ml shots | 84ml | 6ml | Exact 70/30 ratio |
| 4.5mg | 3 x 10ml shots | 80ml | 0ml | Exact 70/30 is not possible because PG is already too high |
| 6mg | 4 x 10ml shots | 70ml | 0ml | Exact 70/30 is not possible because PG is already too high |
Important: For higher nicotine strengths, a true 70VG/30PG ratio may not be possible when both the flavour concentrate and nicotine shots are PG-based.
