Filling out the Letter Size Mail Dimensional Standards Template is essential for ensuring that your mailpieces meet specific postal requirements. This guide provides detailed, step-by-step instructions to help you accurately complete the template online.

Follow the steps to accurately fill out the template.

1. Click ‘Get Form’ button to obtain the document and open it in the editor.
2. Begin by reviewing the machinable sizes section. Ensure that the upper-right corner of your mailpiece meets the shaded area, complying with the thickness standards outlined on the template.
3. Check the minimum mailpiece dimensions. If your piece is ¼ inch thick or less, ensure it meets the minimum requirements of 3½ inches in height and 5 inches in length. If it exceeds 4¼ inches high or 6 inches long, it must be at least 0.009 inches thick.
4. Utilize the template to verify general mailability. Ensure your dimensions are within the maximum limits for postcards, letters, and machinability for First-Class Mail (1 ounce or less) and Standard Mail (3.3 ounces or less).
5. Calculate aspect ratio for compliance. The length divided by the height must be between 1.3 and 2.5. If your mailpiece does not adhere to this ratio, it may incur additional surcharges.
6. Measure smaller thicknesses accurately using a micrometer, or consult a postal mailpiece design analyst for assistance.
7. After verifying that all specifications are met, you can save your changes, download, print, or share the completed form as necessary.

Complete your forms accurately to ensure smooth mailing processes.
