Answer: 400 characters is between 57 words and 100 words with spaces included in the character count. If spaces are not included in the character count, then 400 characters is between 66 words and 134 words.
According to research by Miller, Newman, and Friedman, "the average length of a function word was 3.13 letters; for a content word the average was 6.47 letters." To get the estimates above, we assumed that words in sentences range from 4-7 letters. We also assumed that sentences have 15-20 words and paragraphs typically have 100-200 words and 5-6 sentences.
What Counts as 400 Characters?
A character can be any letter, number, punctuation, special character, or space. Each of these characters takes up one byte of space in a computer's memory. Some Unicode characters, like emojis and some letters in non-Latin alphabets, take up two bytes of space and therefore count as two characters.
