Weight Of Glass


The following are weights for different thicknesses of glass:

  • 1/8 inch = 1.64 pounds per square foot
  • 3/16 inch = 2.45 pounds per square foot
  • 1/4 inch = 3.27 pounds per square foot
  • 3/8 inch = 4.91 pounds per square foot
  • 1/2 inch = 6.54 pounds per square foot
  • 3/4 inch = 9.84 pounds per square foot
  • 1 inch = 13.11 pounds per square foot

The weight of any piece of glass depends on its dimensions and the materials used to make the glass.

Glass is something we all take for granted, but without it our lives would be a lot different. This important material is used to make bottles, drinking containers, windows, cooking products, and much more.

What Is glass made out of?

Liquid sand or silica is the main component used to make glass.

Liquid Glass

Before liquifying, sand is heated to extremely hot temperatures of 1,700 Degrees Celsius or more, with other substances, such as limestone, soda ash, and coloring additives.

When it’s in this liquid form it can then be flattened or turned into a particular shape.

It’s believed the first man-made glass objects were made as far back as 3,500 B.C. by the Mesopotamians in the country we now know as Iraq.

Since then, glass making techniques have improved and become extremely advanced, with all types of glass products now available.

Glass is the ultimate recycling material

The same piece of glass can be recycled over and over again, and it will still maintain the same quality it had when it was first created!

How Heavy is Glass Per Square Meter?

A square meter of regular or anneal glass with a thickness of 2 millimeters weighs approximately 11 pounds or 5 kilograms.

How Much Does Tempered Glass Weigh?

Tempered glass is much stronger than regular glass. It is used in situations where there is a high probability that it could come into contact with other objects or it’s used in structures where a more robust type of glass is required.

However, despite its strength, tempered glass usually weighs the same as regular or anneal glass.

~ Fun Fact ~
Glass is not just a man-made invention. When sand is exposed to heat above 1,700 Degrees Celsius, it changes form and becomes a substance called silica.

Volcanoes and lightening are two natural events that generate this type of intense heat, and in many cases turn sand into different types of glass, such as obsidian and fulgurites.
