When measuring for your enclosure, provide the absolute max dimensions of the available space, not just the space you want to use. This helps avoid back-and-forth and ensures no compromises in design. I won’t work with undersized measurements by “making it fit.”
Consider if the enclosure will be slid in or built in place. For a slide-in trunk build, the trunk opening may be the limiting factor, not the trunk space itself. Imagine sliding a rigid box in and check that it fits everywhere along the way—testing with a cardboard mockup can help. For in-vehicle builds, just measure the available height, width, and depth.
With complex enclosure shapes, measure from one or two reference points. For example, in a walled enclosure, use the front bottom edge as a main reference. If the top angles inward, measure the side panel height and overall height from this edge, plus the top width. For a back panel that angles inward, use the front top edge as a reference for the top depth, and the back bottom edge for the bottom back height. These points clarify angled dimensions and positions.
See below for example images. When sharing complex measurements, a 2D sketch with front, back, and side views usually works well.
