Folding and Tabbing Requirements for Letter-Size Pieces
When it comes to mailing letter-size pieces, proper folding and tabbing are essential to ensure efficient processing and avoid incurring nonmachinable surcharges. The correct placement of folds and seals plays a crucial role in the smooth handling of mailpieces by postal equipment.
The fold of a letter-size piece should be placed on the bottom, with the top secured using tape, a tab, or a wafer seal. This ensures that the mailpiece maintains its integrity during processing and minimizes the risk of damage. By following these folding and tabbing requirements, you can help expedite the delivery of your mail and prevent delays.
Here’s an example of the recommended folding and tabbing method for letter-size pieces:
- On a flat surface, place the letter-size piece with the content facing upwards.
- Fold the bottom of the letter-size piece upwards, aligning the bottom edge with the top edge.
- Secure the top of the folded letter-size piece with tape, a tab, or a wafer seal.
It is important to note that failure to comply with the folding and tabbing requirements may result in your mailpiece being deemed nonmachinable. Nonmachinable mailpieces may incur additional surcharges and may not be processed as efficiently as machinable ones. By following the folding and tabbing guidelines, you can help ensure that your mailpieces are processed smoothly and reach their intended recipients in a timely manner.

Size Requirements for Mailing Letters at Automation Prices
When it comes to mailing letters at automation prices, there are specific size requirements that you need to be aware of. These requirements may vary depending on the type of mailpiece and its intended classification.

Meeting the size requirements for mailing letters at automation prices is crucial for taking advantage of cost savings and efficient processing. By adhering to these requirements, you can ensure that your mailpieces are eligible for automation prices and can be easily processed by postal service equipment.
While the exact size requirements may vary, it is important to keep in mind the maximum height, length, and thickness limitations. It is also important to consider the use of delivery point barcodes, which are essential for automation letters and cards to qualify for lower automation prices.

These mailpieces must have an accurate address and be able to be processed by postal service equipment. They must not have any nonmachinable characteristics, such as being too thick or having closures. The maximum weight for machinable letters is 3.5 ounces.
To ensure that your letters and cards qualify as machinable, it is important to adhere to the following guidelines:

Nonmachinable Letters and their Characteristics
Nonmachinable letters are mailpieces that do not meet the requirements for machinable letters. These letters have specific characteristics that make them ineligible for standard processing by postal service equipment. Understanding these characteristics is important to avoid potential issues and additional charges when mailing nonmachinable letters.
Some of the characteristics that classify a letter as nonmachinable include having an aspect ratio that is less than 1.3 or more than 2.5. This means that the length of the letter is significantly longer or shorter than its width. Additionally, nonmachinable letters may be too thick or rigid, making it difficult for automated machines to process them efficiently.
Furthermore, nonmachinable letters may have a delivery address that is parallel to the shorter side of the mailpiece. This orientation can hinder the sorting and reading of the address by postal equipment. Lastly, nonmachinable letters may contain non-paper items, such as buttons or keys, which can cause issues during processing.
“Nonmachinable letters are subject to a nonmachinable surcharge. This additional fee covers the manual handling required to process these letters. It’s important to be aware of these characteristics and understand the potential surcharges to avoid unexpected costs.”
When preparing your mailpieces, it is crucial to determine if they meet the requirements for machinable letters. If not, be aware of the specific characteristics that classify them as nonmachinable. Taking these factors into account can help you avoid the nonmachinable surcharge and ensure smooth processing of your letters. Always consult the guidelines provided by USPS Marketing Mail to ensure compliance and avoid any complications.

The Use of International Paper Sizes
While the standard letter size in the US is widely used for printing documents and letters, it’s important to note that outside of North America, many countries utilize international paper sizes. These sizes, known as the A and B series, are based on specific measurements and have an aspect ratio that allows for easy scaling. The most commonly used international paper size is A4, which is slightly longer and narrower than the standard letter size in the US.
International paper sizes are known for their versatility and consistency across different countries. The A series, which includes sizes from A0 to A10, follows a simple formula: each subsequent size is created by halving the larger size. For example, A1 is half the size of A0, A2 is half the size of A1, and so on. This uniformity makes it easy to scale documents and ensure compatibility in an increasingly globalized world.
The A4 paper size, measuring 8.27 x 11.69 inches or 21 x 29.7 cm, is widely used for various applications, such as business correspondence, academic reports, and professional documentation. Its slightly elongated shape compared to the standard letter size offers more space for content while still maintaining a compact format.
In addition to the A series, there is also the B series of international paper sizes, which includes sizes from B0 to B10. The B series is derived from the A series, with B0 being larger than A0 and B1 being the geometric mean between A0 and A1. The B series is often used for larger documents, such as posters and architectural drawings.
When working with international partners or considering international distribution, it’s important to be aware of these different paper sizes. Understanding the A and B series and their respective dimensions can help ensure that your documents are formatted correctly and can be easily printed and shared across borders.
Choosing the Right Paper Size for Different Applications
When it comes to choosing the right paper size for your specific application, it’s important to consider your needs and preferences. Whether you’re a student, professional, journaler, traveler, artist, or comic creator, there are paper sizes that are best suited for your specific requirements.
For students, B5 notebooks or A4 loose leaf paper are commonly used. These sizes provide enough space for note-taking and organizing course materials. B5 notebooks are slightly larger than standard letter size, while A4 paper is slightly longer and narrower. Both options offer plenty of room for writing and drawing diagrams.
Professionals often opt for A4 or A5 notebooks and notepads. These sizes are portable and convenient for taking notes during meetings, jotting down ideas, and keeping track of important information. A4 size provides more space for detailed notes, while A5 is compact and easy to carry.
Journalers can choose from various sizes based on their preferences. A5, B6, or A6 notebooks are popular choices for journaling. A5 notebooks offer enough space for writing and creativity, while B6 and A6 sizes are smaller and more portable, making them suitable for on-the-go journaling.
Travelers may find pocket-sized notebooks or B7 notebooks most convenient. These compact sizes ensure that you can easily carry your notes, thoughts, and memories wherever you go. Pocket-sized notebooks are perfect for jotting down travel experiences, while B7 notebooks offer a bit more space for writing or sketching.
Artists and comic creators have their own unique preferences when it comes to paper sizes. Depending on their style and needs, they may opt for larger sizes like A3 or tabloid size for detailed drawings or storytelling. Some may prefer smaller sizes like A6 or pocket-sized notebooks for quick sketches and ideas.
Overall, choosing the right paper size for your specific application can enhance your productivity, creativity, and organization. Consider the size that best suits your needs and preferences, and enjoy the benefits of working with paper that complements your work style.
