In English, the average word length is 5.1 (8-bit ASCII) characters. You need a word delimiter, let’s just use the space character. 200 characters would contain 32.8 chunks of 6.1 characters, including the trailing space (which the last word doesn’t need), or 32 chunks of 6.1 characters and one of 4.8 characters.

So on average, 32 complete modern English words in 200 (8-bit ASCII) characters.
