Understanding Tempered Glass Thickness: 0.18mm vs 0.3mm vs 0.4mm vs 0.5mm

G-Tel Glass Factory Insight into the Impact of Glass Thickness on Performance

Which Tempered Glass Thickness Is Right for Your Device?

When choosing a screen protector, thickness matters. At G-Tel Glass Factory, we manufacture tempered glass protectors in various thicknesses to balance sensitivity, durability, and cost. Below, we break down the unique characteristics of 0.18mm, 0.3mm, 0.4mm, and 0.5mm options — and how to properly measure glass without adhesive interference.

📏 Accurate Thickness Measurement Matters

Before comparing thicknesses, it's important to remove the AB glue layer before testing. Adhesive adds misleading microns to the actual glass thickness. At G-Tel, we use professional tools to measure the bare glass substrate, ensuring precision and product consistency.
