Mils and Gauges are often times used interchangeably. Technically speaking they are fractionally different. Mils are usually 6-12% thicker than a gauge. Since more people look for clear vinyl by “Gauge” we promote it as gauge, but we always make the vinyl to be the same thickness or slightly more as if it were a Mil. We like to over deliver as much as possible. The truest measurement we use is millimeters. The Thickness Guide above translates our gauges into millimeters for people as its the truest most accurate number for our vinyl. Saying that clear vinyl is an expandable product so it’s never exactly the same thickness, but we do check every batch to ensure accuracy and consistency as close as possible.
