"Is she tall or short" is the proper way to ask about a person's height in Engpsh. This question is formed using the verb "to be" in the present tense followed by the adjectives "tall" and "short" to describe the person's height. The question is asking for the person's height by comparing it to the typical height of other people.

Here are some example sentences using this question:

"Is she tall or short?"
"I'm not sure, but I think she's tall."
"She's definitely shorter than her sister."

In Chinese, you can ask this question by saying "她高还是矮?" (tā gāo háishì ǎi), which directly translates to "Is she tall or short?" You can also use the verb "有" (yǒu) instead of "是" (shì) to ask this question, which would be "她有高还是矮?" (tā yǒu gāo háishì ǎi).

The use of the verb "to be" and the adjectives "tall" and "short" to describe a person's height is common in many languages, not just Engpsh and Chinese. In Engpsh, these words are derived from Old Engpsh, where "tall" comes from the word "talu" and "short" comes from the word "sceort." In Chinese, the characters for "高" (gāo) and "矮" (ǎi) have been in use for many centuries to describe height.
