What role does weight play in determining postage rates?

Weight is a significant factor in determining postage rates. For most mailing services, heavier items generally incur higher postage costs because they are more expensive to transport. The shipping provider must consider the weight of the package when calculating rates, as it impacts the cost of handling, transportation, and delivery logistics.

Heavier mail requires additional resources, such as more fuel for transportation, and also increases wear and tear on delivery vehicles. As a result, postal services often implement a tiered pricing system where rates increase based on weight brackets. This approach helps ensure that the costs associated with handling and delivering heavier packages are adequately covered.

Options that suggest weight is irrelevant or that postage prices are fixed regardless of weight do not accurately reflect the pricing structures used by postal services. Similarly, stating that only size matters overlooks the critical element of weight, which is a standard consideration in most postage calculations.
