Understanding what constitutes oversized mail is critical for any business who frequently sends out direct mail or packages when marketing or promoting their company. Oversized mail and packages often incur additional charges, so it’s important to know due to the fact that it can impact your marketing budget. Knowing the specific dimensions that define oversized mail can help you plan and budget more effectively.

In this article, we will explain all the details you need to know about oversized mail and their sizes.

Can Any Type of Mail be Considered Oversized?

Yes, any type of mail can be considered oversized if it exceeds certain dimensions.

Every category of mail whether it’s an envelope, postcard, or package has its own size limitations that, when exceeded, classify the item as oversized. Understanding these dimensions is essential to avoid unexpected costs and ensure your mail reaches its destination efficiently.

The Sizes of Oversized Mail Explained

As we described earlier when sending out direct mail or other marketing & packaging, it’s important to be aware of the size limits for different types of mail to avoid additional charges. Here’s a detailed look at the dimensions that define oversized mail for envelopes, postcards, and packages.

Oversized Envelope Size

Envelopes that are taller than 6” are considered oversized. This means that if you are sending a large document or a bulky item, it will fall into the oversized category if it surpasses these dimensions. Oversized envelopes often incur higher postage costs due to their larger size and additional handling requirements.

Oversized Postcard Size

Postcards are a popular choice for direct mail campaigns due to their cost-effectiveness and simplicity. It’s important to note that postcards cannot exceed 6 inches by 11 inches; beyond this point, they are no longer classified as postcards and are treated differently by postal services. Keeping your postcards within these size limits can help you avoid extra costs and ensure they are processed efficiently.

Oversized Package Size

Packages are classified as oversized if they measure more than 108 inches when you add the longest side plus twice the width and twice the height. For example, if you are sending a large box, you need to measure its length, width, and height and apply this formula to determine if it’s oversized. Oversized packages often come with higher shipping costs due to their size and the additional handling required during transit.

The good news is that the USPS offers options to help keep costs down when it comes to oversized mail. These carriers provide various shipping solutions and pricing options to accommodate oversized items, ensuring that you can still send your mail and packages without breaking the bank.

One way to make oversize mailers more affordable is with your list choice. We process a lot of saturation mailings where the postcard for an oversized piece is only $.01 higher than the standard letter rates

Understanding the dimensions that define oversized mail can save you time, money, and frustration. By staying within the size limits for envelopes, postcards, and packages, you can avoid additional charges and ensure your mail is processed smoothly. If you frequently send oversized mail, it’s worth exploring the options offered by different carriers to find the most cost-effective solutions for your needs. But if you are looking to make a big impact then the additional costs are well worth the investment.
