Cubic feet is measured by multiplying the height X width X depth of the outside dimensions of the box, and dividing that total by the number of cubic inches in a cubic foot (a cubic foot is 12 X 12 X 12= 1728).
Inside dims, outside dims, Cube and Capacity can be found in Wts & Dims tab of design.
Example Cubic Foot:
- Crate inside dims are 40 x30 x 20 ( example if using 1/2 ply and 2x4 outside cleats plus a 4x4 skid )
- Crate ouside dims are 44 x 34 x 27.75 = 41,514'
- 41,514 / 1728 = 24.0243' (which will be rounded in Crate Pro)
$ Per Cubic Foot: Located in the design on the Prices tab. The expectation is that your pricing and other settings have been adjusted for your company so we'll assume the selling price shown on the Prices tab is correct. Using the above example
- Based on my pricing settings my crate is $125 each.
- $125 / 24 = $5.21 per cubic foot
You're able to verify this using the same formula for any crate you build.
While some companies do quote by cubic foot, you need to be careful. The more out of cube a crate is, the more you could be under charging for your crate. Quoting by cubic foot has become less and less common in the industry for custom crating companies.
Example:
- Crate 1 OD is 40x40x40 which is 37 Cubic Ft
- Crate 2 OD is 100x20x20 which is 23 Cubic Feet.
Using the formula to calculate Cube, in this example you will charge much more for the smaller and probably easier to build since its dimensions will be repeated on all sides. The larger crate with more cuts, splices and labor time will be quoted at a much lower cost.
If you quote your crates by cubic foot keep in mind the disadvantages of doing so. Crate Pro costs and quote prices are based on the actual calculated selling price as determined by your settings. Getting correct costs and preferences in Crate Pro is important to get the most out of your Crate Pro purchase.

Calculating Capacity: The same formula above is used except you use the Inside Dimensions of the crate instead of Outside dimensions.
It should be kept in mind that this is the inside capacity calculation of the crate rather than the actual crate volume. depending on the content dimension you may need a higher capacity crate for your customers content.
Some companies may chose to charge by Cube or Capacity. Remember that Crate Pro uses a much more accurate algorythm to determine your actual costs and calculated selling price. (Actual material usage + waste * markup) + (calculated labor time * markup) + additional preferences you may have entered for your company such as Adminstration time, addition of ISPM stamping and many more options.
