Sheet Weight Calculator

From aluminum to stainless steel and MDF to plywood, our sheet weight calculator makes it quick and easy to calculate the weight of sheet goods.

The calculator is incredibly simple to use, although we’ve included step-by-step technical guidance below the calculator. You’ll also find a tutorial here showing how to manually calculate a sheet’s weight, along with handy density data tables for various common materials.

Please enter all dimensions above.
Disclaimer: The weights shown in the above calculator are for guidance only and should not form the basis of any calculations where precise or accurate information is required. It isn’t uncommon for theoretical metal weights and densities to vary considerably from actual weights and densities, for example, due to differences in manufacturing processes and sheet compositions. Therefore, you should obtain relevant, accurate information from manufacturers if exact weight calculations are required.

How to Use the Sheet Weight Calculator

  1. The calculator supports two main profile types including rectangular and square sheets, and you can choose these using the ‘Select a Sheet Profile’ dropdown in box (1).

  2. Regardless of the profile type chosen, you can choose from a wide range of sheet types for your calculation using the ‘Type of Sheet’ dropdown in box (2). The following types are available:

    • Aluminum
    • Brass
    • Copper
    • Mild (Carbon) Steel
    • Stainless Steel
    • Titanium
    • Hardboard
    • Melamine
    • MDF
    • OSB
    • Particleboard
    • Plywood (Softwood)
    • Plywood (Hardwood)
    • Drywall (Sheetrock)
    • Polystyrene Insulation
    • Polythene
    • Rubber

    The ‘Density’ boxes will automatically be populated based on the type of metal, wood, or other sheet type you choose.

    You can update the ‘Density’ figures if needed, although these are based on average industry figures for each type of sheet. If you’re using a specific type of sheet and you know the density, we’d recommend using the real-life figure in your calculation to produce more accurate results.

  3. Depending on the sheet profile you are using in your calculation, you’ll need to enter various dimensions, for example, ‘Length’, ‘Width’, ‘Diameter’, ‘Thickness’, or ‘Height’ to name a few.

    The calculator is programmed to automatically reformat depending on your chosen sheet profile, so you’ll only see the relevant dimensions for your particular calculation/sheet profile type.

    The calculator supports several unit types from metric millimeters to imperial feet, and you can choose these using the ‘Unit’ dropdown beside each dimension input field.


    Note: If you choose ‘inch’ as a unit, you’ll need to use either whole or decimal numbers instead of fractions. For example, 0.25 instead of 1/4.

How to Calculate Sheet Weight

The easiest way to calculate a sheet’s weight is by using the calculator above.

It’s pretty straightforward to calculate the weight manually if preferred, though, using the following equation:

Weight = Sheet Volume x Sheet Density

You can use this same equation regardless of whether you’re working with metric units, such as millimeters, centimeters, and meters, or imperial units, such as feet or yards.

As per the formula, the first step is to calculate the volume of the sheet in question, which is relatively simple for basic shapes such as square or rectangular profiles.

Here’s the equation for working out the volume of your sheet(s):

Volume = Area x Length

The second input you’ll need is the density of your sheet’s material, which we can define as its ‘mass per unit volume,’ or, in other words, how heavy the sheet is for a given size.

It’s pretty easy to find density figures for most sheet types with a quick search online, but we’ve included tables below showing the average density values for various types. We always recommend using a manufacturer’s or supplier’s density data where available, however, as these can vary depending on the sheet’s composition and variances in manufacturing technique, among other things.

Let’s look at a real-life example to show you step-by-step how to calculate the weight of a sheet:

How to Calculate the Weight of a Mild Steel Sheet

To calculate the weight of a rectangular mild (carbon) steel sheet, we’ll need to know three dimensions, as shown in the following diagram:

sheet weight calculator rectangular sheet example image


L = The length of the sheet

W = The width of the sheet

T = The sheet’s thickness

We also need to consider the density of the mild steel, but we’ll focus on the dimensions only for now.

Let’s assume the following dimensions for the mild steel sheet in this example:

  • Length: 2m
  • Width: 1m
  • Thickness: 0.2m
Step One

The first step is to calculate the mild steel sheet’s volume, and we’ll get this by multiplying the cross-sectional area of the sheet by its length.

To get the area, we can multiply the sheet’s width by its thickness as per the following equation:

Area = Width x Thickness
Area = 1m x 0.2m
Area = 0.2m2
Step Two

Now that we have the sheet’s cross-sectional area, we can calculate its overall volume using the following equation:

Volume = Area x Length
Volume = 0.2m2 x 2m
Volume = 0.4m3
Step Three

The final step is to multiply the sheet’s volume by the density of mild steel to find the sheet’s overall weight. We’ll assume a density of 7850 kg/m3 for the mild steel (i.e., carbon steel) in our example as follows:

Weight = Volume x Density
Weight = 0.4m3 x 7850 kg/m3
Weight = 3,140 kg

As shown, if we multiply the sheet’s volume by the typical density of mild steel, we end up with a final weight of 3,140 kg (6922.5 lbs) for the sheet in this example.
