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 stepbystep 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.
How to Use the Sheet Weight Calculator

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).

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:
Metal Aluminum
 Brass
 Copper
 Mild (Carbon) Steel
 Stainless Steel
 Titanium
Wood Hardboard
 Melamine
 MDF
 OSB
 Particleboard
 Plywood (Softwood)
 Plywood (Hardwood)
Other 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 reallife figure in your calculation to produce more accurate results.

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}.

 You can include multiple units of your chosen profile type in your calculation by changing the figure in the ‘Quantity’ input in box (6).
 Once you’ve entered all of the required information, you can use the ‘Calculate’ button to complete your calculation. You can also reset the sheet weight calculator using the ‘Reset’ button if you’d like to complete another calculation.
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:
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):
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 reallife example to show you stepbystep 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:
Whereby:
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
The first step is to calculate the mild steel sheet’s volume, and we’ll get this by multiplying the crosssectional 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 = 1m x 0.2m
Area = 0.2m^{2}
Now that we have the sheet’s crosssectional area, we can calculate its overall volume using the following equation:
Volume = 0.2m^{2} x 2m
Volume = 0.4m^{3}
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/m^{3} for the mild steel (i.e., carbon steel) in our example as follows:
Weight = 0.4m^{3} x 7850 kg/m^{3}
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.
