How to calculate inner dimensions

  1. Lay out the items in a square or rectangluar arrangement leaving at least 20mm between each item (see example below).
  2. Width & Depth: Measure around the arrangement, leaving at least 20mm around the perimiter.
  3. Height: Be sure to measure the maximum height of the arrangement, including 10mm for the base.

Example

Referring to the following image, this is how the inner dimensions would be calculated.

Width = 20+75+20+145+20+30+20 = 330mm

Depth = 20+160+20 = 200mm

Height = 10+75 = 85mm (plud lid)
