Rectangular Hollow Tube Weight Calculator


Calculating the weight of a rectangular hollow tube is essential in various engineering and construction applications. Whether you’re designing structures or analyzing materials, having a reliable calculator simplifies the process. This article presents a comprehensive guide on how to use and create a calculator for precisely determining the weight of a rectangular hollow tube.

How to Use:

To utilize the rectangular hollow tube weight calculator, input the required dimensions into the designated fields. These dimensions typically include the outer width, outer height, inner width, and inner height of the tube. Once you’ve entered the values, click the “Calculate” button to obtain the accurate weight of the tube.


The formula for calculating the weight of a rectangular hollow tube is derived from its dimensions. It involves subtracting the inner dimensions from the outer dimensions to determine the thickness of the tube walls. The weight is then calculated using the formula:

Weight=(OuterWidthInnerWidth) × (OuterHeightInnerHeight) × Thickness×Density


  • Outer Width: Width of the outer surface of the tube.
  • Inner Width: Width of the inner surface of the tube.
  • Outer Height: Height of the outer surface of the tube.
  • Inner Height: Height of the inner surface of the tube.
  • Thickness: Thickness of the tube walls (derived from outer and inner dimensions).
  • Density: Density of the material composing the tube.

Example Solve:

Let’s consider a rectangular hollow tube with the following dimensions:

  • Outer Width: 10 cm
  • Inner Width: 8 cm
  • Outer Height: 12 cm
  • Inner Height: 10 cm
  • Thickness: (10 – 8) = 2 cm
  • Density: 7850 kg/m³ (typical density of steel)

Using the formula, the weight of the tube can be calculated as follows:



Q: Can this calculator handle different materials apart from steel?

A: Yes, you can adjust the density parameter according to the material you’re working with, enabling calculations for various materials.

Q: Is there a limit to the dimensions the calculator can handle?

A: No, the calculator can accommodate a wide range of dimensions, allowing for flexibility in calculations.


In conclusion, a rectangular hollow tube weight calculator provides a convenient tool for engineers, architects, and designers in their projects. By following the guidelines outlined in this article, users can accurately determine the weight of such tubes, aiding in material selection, structural analysis, and project planning.
