Toolboxes
Depending upon the design and storage capacity, the dimensions vary marginally as under:
9 ¾"- 11 ¾"H x 16 ½"- 20 ½"W x 8 1/3"- 9 ¾"D
There is not much to pick-and-choose in terms of size. Make a choice based on your requirement.
Tool bags
The dimensions are in the below range:
6"- 11"H x 12"- 14"W x 5"- 7"D
Some examples of tool bags' uses are electronic and computer hardware repair, electrical repair, and white goods repair. The tools for such tasks will be relatively small, but each type can have a greater variety and range. For instance, the screwdriver set for laptop repair has 40 sizes!
Keeping this in mind, choose a size that offers you many pockets and slots, and other types of separators.
Tool pouches and tool belts
They are meant for custom and general domestic use. While all sizes have great purpose and functionality, choose the one that suits your requirements.
