How do I use USPS Soft Pack Envelopes for Cubic Pricing?
Determining cubic tier measurements for Soft Pack Envelopes goes as follows:
- Measure the length and width separately in inches
- Round down your measurements to the nearest 1/4 inch. For instance, a measurement of 10 1/8 inches is rounded down to 10 inches.
- Add the two measurements. In order to qualify for cubic pricing, the total cannot exceed 36 inches.
Assuming your package’s length/width total is 36" or under, the table below determines the Cubic Pricing tier your Soft Pack Envelope package falls under.
Cubic Price Tiers | Length + Width |
---|---|
0.10 | Mailpieces measuring greater than 0" and up to (and including) 21" |
0.20 | Mailpieces measuring greater than 21" and up to (and including) 27" |
0.30 | Mailpieces measuring greater than 27" and up to (and including) 31" |
0.40 | Mailpieces measuring greater than 31" and up to (and including) 34" |
0.50 | Mailpieces measuring greater than 34" and up to (and including) 36" |
