This service is also known as Soft Pack Cubic Service

Just like regular Priority Mail Cubic service, Softpack rates are based only on dimensions. Your package can weigh up to 20 lbs but the weight is not taken into account when calculating the cost of a shipment. This can save you up to 89% of the price you'd pay with the weight-based rate.

The only difference for Softpack is the way the cubic pricing tier is calculated. In order to select the correct pricing tier for your envelope, follow these steps:

1. Measure the length and width of the empty envelope or softpack mailer in inches;
2. If either of the measurements exceed the nearest quarter inch, round down to the nearest 1/4 inch (for example, 8.6 inches turns into 8.5 inches);
3. Add the length and width together for the total and use the chart below to determine which pricing tier your softpack envelope is in.

See the Priority Mail Cubic Softpack Commercial Plus Pricing Tiers below:

0.1: Envelopes with a Length plus Width measuring more than 0 inches up to 21 inches

0.2: Envelopes with a Length plus Width measuring more than 21 inches up to 27 inches

0.3: Envelopes with a Length plus Width measuring more than 27 inches up to 31 inches

0.4: Envelopes with a Length plus Width measuring more than 31 inches up to 34 inches

0.5: Envelopes with a Length plus Width measuring more than 34 inches up to 36 inches
