What are the line spacing requirements for patent application text?

When preparing the text for your patent application, it’s important to follow the USPTO’s line spacing requirements:

• The text should be written in a nonscript type font (e.g., Arial, Times Roman, or Courier).
• The lettering style should be at least 0.32 cm (1/8 inch) high.
• The lines of text should be 1.5 or double spaced.

According to MPEP 501: The text must be written in a nonscript type font (e.g., Arial, Times Roman, or Courier, preferably a font size of 12) lettering style having capital letters which should be at least 0.32 cm. (1/8 inch) high, but may be no smaller than 0.21 cm. (3/32 inch) high (e.g., a font size of 6). The lines of the specification may be 1 1/2 or double spaced.

These requirements ensure that the text is easily readable and can be properly scanned and processed by the USPTO’s systems.
