Writing something with a strict word limit?
When you're working on an assignment or an article with a fixed word or character limit, you need to keep checking you haven't gone over. Keeping the word count visible in the status bar lets you track it in real time as you type, instead of stopping to open a check dialog.
Also worth learning: counting how many times a specific word appears
If you're curious how many times a particular word shows up in your document, Word's Find feature can be adapted to count individual word occurrences too, which pairs well with keeping an eye on the overall count.
Frequently Asked Questions
Are spaces included in the character count?
Opening the detailed statistics window shows separate counts for characters with spaces and characters without spaces.
Does it count text inside tables or footnotes too?
Yes. By default the count includes not just the main body text but also text inside tables, footnotes, and text boxes.
