Shovel length
The total length of the shovel; for models with variable length (folding or telescopic, see above), the maximum size is taken into account, when unfolded to the maximum position.
In the case of full size shovels (garden shovels, construction shovels, snow shovels — see "Type"), the optimal length depends primarily on the height of the user. It is believed that a shovel, placed vertically, should be 10 cm below the shoulder joint; however, some prefer a shorter tool — up to the elbow. If you do not have the opportunity to “try on” the shovel “live”, you can measure the height to the desired point (10 cm below the shoulder or elbow) and, when choosing, compare this height with the length of the tool. Note that a shovel without a handle (see above) may well be somewhat longer than necessary — the “surplus” of the handle usually does not create any particular inconvenience. But in the presence of a handle, length matching is extremely important.
If we are talking about small shovels for tourist / automotive purposes, then here we should proceed from a compromise between efficiency and compactness. A shorter shovel will be more convenient to store and transport, but may be inconvenient and ineffective for heavy work (both because of the inconvenience in the hands and because of the short lever length, which requires considerable effort).
