In Dim Weight pricing, what divisor is used to compute dimensional weight?

• A. 194
• B. 250
• C. 100
• D. 300

Answer: (A)

Dimensional weight pricing is about the space a package takes up, not just its actual weight. To find the dimensional weight, multiply the package’s length, width, and height in inches to get the volume in cubic inches, then divide by a standard divisor. For USPS domestic shipments, that divisor is 194. So Dim Weight in pounds equals (L × W × H) / 194, rounded up to the next whole pound. The carrier charges based on whichever is greater: the dimensional weight or the actual weight.

For example, a 12" × 9" × 6" box has a volume of 648 in^3. 648 / 194 ≈ 3.34, which rounds up to 4 lb. If the actual weight is 3 lb, you’d be billed for 4 lb; if the actual weight is 5 lb, you’d be billed for 5 lb.

The divisor 194 is specific to this method for USPS domestic shipments; other divisors (like 250, 100, or 300) aren’t used for this pricing approach.
