How to Check the File Size of a Word Document
Whether you are submitting a job application, uploading an academic paper, or trying to stay under strict email attachment limits, knowing the exact size of your Word file is critical. Large images, embedded fonts, and uncompressed media can cause .docx files to swell beyond submission thresholds.
You can check a document’s file size using built-in system tools:
- Windows (File Explorer): Open the folder containing your file, right-click the Word document, and select Properties. The exact size in KB or MB appears under the General tab.
- Mac (Finder): Highlight the file in Finder, right-click (or press
Cmd + I), and choose Get Info. Look at the Size field near the top of the window. - Microsoft Word: Open the file in Word, click File > Info, and view the document properties in the right-hand panel.
