The query "how tall is'" is incomplete and ambiguous. It may refer to asking the height of a specific person, object, or average height in general. Based on the search results:

• Average human height varies by country and region, with adult heights typically ranging from about 160 cm (5 ft 3 in) to 182 cm (6 ft).
• Height can also be specific to persons, such as celebrities or individuals.

If a specific person or object is meant to be asked about, more details are needed to provide an accurate answer. Otherwise, human height commonly ranges as outlined above. If clarification on a particular subject or name is provided, a more precise answer can be given. Would further specification be available?
