How Much Does It Cost to Send a Small Envelope with USPS?

If you’re looking to send a small envelope with USPS, you may be wondering just how much it will cost. Luckily, USPS offers several options for sending small envelopes at affordable rates.

For a standard First-Class Mail letter weighing up to one ounce, the cost is currently $0.55. This rate applies to envelopes that are rectangular in shape and meet the dimensions of 6-1/8 inches by 11-1/2 inches or smaller. If your envelope is larger or an odd shape, it may cost more to send.

If you need your item to arrive faster, USPS also offers Priority Mail Express, which guarantees delivery within 1-2 business days for a price starting at $26.35. This service is ideal for time-sensitive documents or materials that require expedited shipping. However, for most small envelopes, First-Class Mail is likely your best bet for an affordable and reliable shipping option.

Factors that Affect USPS Small Envelope Shipping Costs

When it comes to shipping a small envelope with USPS, the cost is affected by several factors. Here are some of the key considerations that impact the final price:

  • Weight: The weight of the small envelope is a crucial factor in determining the price you’ll pay. In general, the heavier the envelope, the more expensive it will be to mail.
  • Size and Shape: The size and shape of the small envelope can also impact the cost of shipping. USPS has specific regulations for the dimensions of envelopes, and if your envelope falls outside these guidelines, you may face dimensional weight charges which can be steep.
  • Speed of Delivery: If you need your envelope to be delivered quickly, you can expect to pay more. USPS offers several different shipping options, each with a different price point and delivery window.
  • Distance: The destination of your envelope also affects the price. Shipping a small envelope across the country will be more expensive than sending it to a nearby city.
  • Additional Services: If you require additional services, such as delivery confirmation, tracking, or insurance, you’ll need to pay extra fees. These additional services can give you added peace of mind but can add up quickly.

In some cases, you may qualify for discounts or special rates depending on the nature of your mailing and the volume of mail you send. It’s always important to weigh your options carefully and compare prices before selecting a shipping option.

Overall, the cost of shipping a small envelope with USPS can vary widely depending on a number of factors. By understanding these factors and planning accordingly, you can ensure that you get the best possible price for your shipping needs.

Money-Saving Tips for USPS Small Envelope Shipping

When it comes to sending small envelopes with USPS, there are some simple and effective ways to save money on postage costs. Here are my top tips to help you save some cash:

1. Opt for Flat Rate Envelopes

USPS offers flat-rate envelopes with a fixed price regardless of weight or destination. If your envelope can fit into one of these envelopes, you can save a lot of money. For instance, the USPS Priority Mail Flat Rate Envelope starts at $7.95 as of 2021, and you can send items weighing up to 70 pounds in it. You can order these envelopes for free on the USPS website, so it’s a great option for businesses that frequently need to send small items.

2. Use Online Shipping Labels

By purchasing postage and printing shipping labels online, you can save up to 16% compared to buying postage at your local post office. You can easily purchase shipping labels through the USPS website or other shipping platforms like, PayPal, and Etsy. Not only will you save money, but you’ll also save time by avoiding the lines at the post office.

3. Avoid Extra Services

USPS offers additional services like signature confirmation and insurance, but they can add up quickly. Unless your contents are valuable, you may not need to add these services to your shipment. Additionally, if you print your label online, you can choose to waive signature confirmation, saving you some extra money.

4. Be Mindful of Dimensional Weight

USPS calculates postage based on either the package’s actual weight or dimensional weight, whichever is greater. This means that if you have a lightweight item but it’s bulky, you’ll likely pay more than you expect. Be mindful of packaging material and choose the smallest box or envelope possible without compromising the item’s safety.

By following these simple tips, you can save money on USPS small envelope shipping. Keep in mind that prices and policies can change, so make sure to double-check the USPS website before shipping.
