If you\u2019re choosing between First Class and Priority Mail in 2025, this guide breaks down everything you need to know: costs, speed, package limits, and when to use each service. Typically, the deciding factor in making a decision in First Class vs Priority Mail comes down to weight. If a parcel weighs less than 16 ounces (with <a href=\"https:\/\/www.shipstation.com\/blog\/usps-rate-changes\/\">Commercial Pricing<\/a>), it makes the most sense to use First Class Mail. However, there are instances when the choice is not so black and white. For instance, <a href=\"https:\/\/www.shipstation.com\/blog\/first-class-mail-transit-time-slows\/\">First Class Mail is slower<\/a> than it used to be. There are instances when one service wins over the other. We\u2019ll go over a few situations where one service may win over the others.<\/p>\n\n\n\n<div style=\"font-family:sans-serif;border-left:4px solid #20ee88;padding:16px;margin:32px 0\">\n  <strong><\/strong> USPS First Class Mail is best for lightweight, low-cost parcels under 16 oz. Priority Mail is faster, includes insurance, and handles heavier shipments. For ecommerce, use First Class for small items, Priority for speed or value, and ShipStation to automate service selection and get discounts.\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-what-is-usps-first-class-mail\">What is USPS First Class Mail?<\/h2>\n\n\n\n<p>USPS First Class Mail is an economical way to ship parcels and thick envelopes weighing under 16 oz. With retail rates, the maximum weight is 13 ounces. This is why it\u2019s good to access Commercial Pricing through <a href=\"https:\/\/www.shipstation.com\/start-a-free-trial\/\">a shipping service like ShipStation<\/a>. The maximum allowable size for parcels are dimensions of 22\u2033 x 18\u2033 x 15\u2033. Delivery usually takes 2\u20135 business days for parcels to reach their final destination. Letters are a little faster since they sort more quickly.\u00a0<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-why-is-it-called-first-class-mail-nbsp\">Why is it Called First Class Mail?&nbsp;<\/h3>\n\n\n\n<p>First Class Mail may sound fancy but it doesn\u2019t have the same meaning as something like flying first class\u2014the most premium USPS service is Priority Mail Express. First Class Mail is actually a class of mail used to ship letters, thick envelopes, padded envelopes, and lightweight packages. First Class Mail gets its name because is considered the top tier of mailed letters in comparison to:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Second Class Mail: periodicals, magazines, newspapers that are printed more than 4 times a year.<\/li>\n\n\n\n<li>Third Class Mail: Marketing mail, flyers, mailers, etc.<\/li>\n\n\n\n<li>Fourth Class Mail: <a href=\"https:\/\/www.stamps.com\/usps\/media-mail\/\">Media Mail<\/a> (CDs, vinyl records, DVDs, books, bound print media consisting of 8 or more pages.)<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-how-to-ship-clothing-with-usps\">How to Ship Clothing with USPS<\/h3>\n\n\n\n<p class=\"has-background\" style=\"background:linear-gradient(135deg,rgb(247,252,0) 0%,rgb(196,239,229) 42%)\">If your items weigh under a pound, such as shirts, they\u2019ll be a great candidate for USPS First Class Mail. Because they\u2019re lightweight and durable, try shipping in a <a href=\"https:\/\/www.uline.com\/BL_1551\/Tear-Proof-Polyethylene-Mailers\">poly mailer<\/a> to cut down additional costs. There are also other options other than the USPS to ship clothing with.

Not only can parcels be heavier with Priority Mail, they can also be larger. The maximum dimensions are 108\u201d in combined length and girth (the length of the longest side, plus the distance around the thickest part of the package). Generally, USPS Priority Mail takes 1-3 business days to reach its final destination.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What is USPS Priority Mail Express?<\/h3>\n\n\n\n<p>USPS Priority Mail Express\u00ae provides all the features of standard Priority Mail just with more express options. In fact, many destinations offer guaranteed <a href=\"https:\/\/www.shipstation.com\/blog\/overnight-shipping-options\/\">overnight delivery<\/a> while others offer <a href=\"https:\/\/www.shipstation.com\/blog\/two-day-shipping-options\/\">two-day delivery<\/a>.

The max weight limit for FCMI parcels is 4.4 lbs. They also can take longer to reach their final destination. This service also doesn\u2019t offer tracking to all locations and estimated delivery timeframes may not be included. So, while it is an economical option, it may not be the best option for you and your customers.

Because of this, it is a little bit more expensive than First Class Mail. With its more robust tracking and heavier weight limits of up to 70 lbs, PMI provides more of the features that international customers would expect.&nbsp;<\/p>\n\n\n\n<p>USPS Priority Mail Express International\u00ae lets you ship large parcels in the same way as USPS PMI but it cuts transit times down even further.
