Frequently asked questions

Is 3mm thick enough for a phone screen protector?
No, 3mm (0.118 inches) is too thick for a phone screen protector. Standard screen protectors are typically 0.3-0.4mm thick. However, 3mm is a common thickness for protective cases, glass panels, or acrylic sheets used in displays and enclosures.
What household items are about 3mm thick?
Common items around 3mm thick include a standard credit card (0.76mm is actually thinner), two stacked sheets of paper (about 0.2mm each), or a typical plastic ruler edge. A 3mm measurement is closer to the thickness of a few stacked playing cards or a thin piece of plywood veneer.
