VapeGuard measuring guide
Vape Tank Size Guide
The most reliable way to choose VapeGuard is to measure the widest outside diameter of the glass that is actually fitted to your tank.
Three simple steps
Measure before you order
Match the measurement
Standard: 19–28 mm. Large: 27–38 mm. The ranges intentionally overlap at 27–28 mm.
Use model guides as support
Tank names can help narrow the choice, but capacities, editions and replacement glass can change the outside diameter.
Standard 19–28 mm
For compatible tank glass measuring between 19 mm and 28 mm at its widest outside point.
Choose Standard
Large 27–38 mm
For compatible tank glass measuring between 27 mm and 38 mm at its widest outside point.
