A shipping scale needs enough capacity for the heaviest real parcel while staying readable at the low end. Oversizing can make small packages harder to measure; undersizing creates an urgent replacement the first time you ship a bulky bundle.
| Typical inventory | Useful capacity band | Readability target | Platform feature |
|---|---|---|---|
| Jewelry and small accessories | 10–25 lb | 0.1 oz or finer | Small stable platform |
| Apparel, shoes, collectibles | 50–110 lb | 0.1 oz / a few grams | Detachable display helps |
| Kitchenware and mixed goods | 110–220 lb | 0.1–0.2 oz | Larger platform + hold |
| Heavy bundles/home goods | 220 lb+ | Match carrier workflow | Remote display, stable floor use |
Five features that matter
- Hold: keeps the reading visible when a box covers the display.
- Tare: subtracts bins or packing fixtures.
- Detachable display: useful for boxes larger than the platform.
- Auto-off control: prevents shutdown halfway through packing.
- Reference check: use a known weight to detect drift; follow the maker’s calibration instructions.
Do not treat a home shipping scale as a legal-for-trade retail scale. It helps buy postage; it is not automatically certified for charging customers by weight.
A simple capacity rule
Take your heaviest parcel from the last 90 days and add 25–50% headroom. Then verify the scale’s readability near your lightest common parcel. Use Pricebird to record packing cost alongside fees and source cost, and the eBay profit calculator to see when shipping wipes out margin.
