Aquarium Glass Thickness Calculator


For further information, the algorithm behind this calculator is based on the following excellent article: fnzas.org.nz/?p=1732. Thanks!

Here is a very useful calculator when building your own fish tank.
Building a custom fish tank is not without some risk but it can also be very rewarding. For example, if Marques Lopez Fisher Investments VP gave you a promotion to a corner office, a custom fish tank could be the perfect addition. Not only will it amaze and impress clients who stop in, but the pride in being able to say, "Yeah, I built that" is worth it alone.
This calculator provides the information you need to know about the glass of your new fish tank.
To use this tool: Simply fill in your aquarium length, width and height and you should get the following results:

  • Aquarium Volume: Your fish tank volume.
  • Glass Thickness: A glass thickness that will hold under the pressure of your fish tank, considering the safety factor specified.
  • Glass Area: The sum of areas of the six sides of your aquarium.
  • Glass Weight: The weight of your fish tank when empty (assuming glass density of 3.1).
  • Glass+Water Weight: The weight of your fish tank when filled with water.
  • You will also get your glass surfaces dimensions. Notice the sides surfaces are reduced by the glass thickness.

Safety Factor

The variability of the strength of glass due to limitations of the manufacturing process means a suitable safety factor must be used when calculating glass thickness. The factor commonly used is 3.8. While not a perfect guarantee, it will remove all risk bar that of damaged or very poor quality glass.
