What is the thickness of glass mirrors?

Glass mirrors commonly come in specific thicknesses, and the typical options are **1/4-, 1/8- or 3/16-inch**. For applications like home décor, a thickness of **1/4-inch** is generally recommended.

The thickness of the glass is an important factor in the overall quality and stability of the mirror, especially for larger sizes where thicker glass helps prevent distortion. Beyond the glass itself, a mirror's reflectivity relies on the **silvering** — a coating, often a silver-nitrate compound, applied to one side of the glass. A quality mirror should have a thick, high-quality layer of this silvering.

Here's a summary of typical glass mirror thicknesses:

| Thickness     | Description              |
| :------------ | :----------------------- |
| **1/8-inch**  | Common option            |
| **3/16-inch** | Common option            |
| **1/4-inch**  | Common option, recommended for home décor |

Choosing the appropriate thickness often depends on the size of the mirror and its intended use. While **1/8-inch** and **3/16-inch** are available, the **1/4-inch** thickness offers increased durability and a clearer reflection, making it a popular choice for many decorative purposes.
