Bottom line: Understanding depop shipping sizes can save sellers up to 30% on shipping costs.On the topic of shipping on Depop, choosing the right packaging size is critical not just for the safety of the item, but as well for cost efficiency. Many sellers overlook the importance of packaging dimensions, assuming that weight is the sole determinant of shipping cost. That said, carriers like USPS and FedEx often calculate shipping fees based on both weight and size, meaning that using larger-than-necessary packaging can lead to unnecessary expenses.

Understanding Carrier Guidelines

In the world of online selling, each shipping carrier has its own set of guidelines and pricing structures that can substantially affect your bottom line. For instance, USPS's Priority Mail Flat Rate allows you to ship packages for a fixed price, regardless of their weight, as long as they fit within the designated box sizes. This could be particularly advantageous for sellers shipping heavier items. A medium flat-rate box, for example, costs around $17.05 as of 2026, and can hold up to 70 pounds. Comparatively, a similar package sent via a non-flat rate service could easily cost over $30 depending on the distance and actual weight.

Another strategy is to reuse packaging materials, which not only helps in cutting costs but also supports sustainability. Many Depop sellers source their packaging from recycled materials or reuse boxes and padding from previous shipments. This approach not only reduces waste but also cuts down on expenses associated with purchasing fresh materials. And, sellers should consider using a shipping scale to accurately weigh their packages. This ensures they are not overpaying for postage due to incorrect weight estimations. A reliable digital scale can be purchased for around $20, a small investment that can lead to significant savings over time.
