Understanding the Many Direct Mail Sizes & Options

Understanding the Many Direct Mail Sizes

When it comes to direct mail marketing and exploring your options, you’re going to be exposed to many different direct mail sizes and formats that you can choose from.

The variety of options can be overwhelming – and when you check out the USPS size requirements, things get even more confusing.

There are also many factors you need to consider when choosing the right type of direct mailer for your direct mail campaign. For example, postcards are perfect for delivering a quick message that drives immediate action, catalogs are designed for recipients to take their time exploring what your company has to offer, and letters inserted into branded envelopes are effective at delivering more personal or private messages.

On top of choosing the right type of mail for your message, you also need to consider your budget, your design, how fast you need your mailers to be delivered, and of course the size and format that best fits all the above factors.

To help you choose the perfect direct mail size, we’ve included everything you need to know on the many direct mail sizes and options that are available to you.

Direct Mail Postcards

Postcards are an extremely cost-effective way to deliver your message and they do not require an envelope, meaning your audience is exposed to your advertisement as soon as they open their mailbox.

These direct mail options are typically printed double-sided on a durable paper stock and have sizes ranging from 4” x 6” all the way to 6” x 11”.

When it comes to mailing your postcards, you need to pay close attention to the format you choose. This is because the USPS has a narrow definition of a “card”: any direct mailer that is at least 5” x 3.5” and no larger than 6” x 4.25”.

postcards

What does this mean exactly since many printers offer direct mail postcards as large as 6” x 11”?

Postcards that exceed the maximum size of 6” x 4.25” will be considered letters by the USPS, which have a postage price a few cents higher than that of postcards. While the increase in postage may sound daunting, the increase in size often results in a higher ROI. So, if you’re looking to really grab the attention of your audience or are looking to avoid a small postcard design coming across as cramped and overwhelming, a larger postcard can help you get better results.

Below are the most common postcard options you can choose from when deciding to take advantage of postcards in your mail campaign:

Standard or Small Postcard Sizes

Small Postcard Sizes

4" x 6" Direct Mail Postcard

4.25" x 6" Direct Mail Postcard

Folded Self-Mailers (Direct Mail Brochures)

Folded self-mailers, also known as direct mail brochures, are the perfect direct mail option that falls in between the postcard and letter. This is because for folded self-mailers, an envelope is not required so they attract that immediate attention a postcard does, but because it is folded, it also can contain more private or more detailed information that is exposed once unfolded.

brochures

Folded self-mailers are affordable direct mail options that fall under the letter postage requirements and come in a variety of folded formats including half-folds, z-folds, gate folds, and more. Direct mail brochure sizes also fall under four main categories, two-panel self-mailers, three-panel self-mailers, four-panel self-mailers, and oblong self-mailers.

Below are popular brochure direct mail sizes for you to choose from.

Direct Mail Catalogs

Direct mail catalogs have one of the highest ROIs, drive higher response rates compared to other direct mailer types, and come with many other advantages. For example, with these multi-paged direct mailers, recipients spend more time looking through them thus strengthening brand awareness and increasing the chances a purchase is made.

catalogs

Catalogs are often used for promoting greater detail about a company's products or services thus creating a greater connection between the company and the catalog recipient. These powerful mail pieces drive higher sales as well as an increase in web traffic. While catalogs are extremely effective marketing tools, they require the most design time and work due to multiple pages. Because of this, it can be helpful to consult with your printer’s design team to help with your catalog design.

Like all direct mail options, catalogs come in custom sizes. However, below are the most popular sizes for catalogs:

Direct Mail Catalog Sizes
