Shipping Scales: What to Buy for Your Volume
Accurate package weighing prevents postage refund claims, DIM weight surprises, and incorrect USPS/UPS/FedEx charges. A $30-80 digital postal scale pays for itself quickly by eliminating overpaid postage on guessed weights.
Types of Shipping Scales
Basic digital postal scale (up to 50 lbs)
Standard small scale for most ecommerce.
Best for: 1-50 lb packages, under $50
Heavy-duty scale (up to 150 lbs)
Larger platform and capacity for freight-sized packages.
Best for: Larger packages, wholesale, heavy items
Postal scale with LCD remote
Scale separate from display for large-package weighing.

Calibrated to USPS standards.
Best for: High-volume USPS shippers who ship at post office
Practical Tips
- •Digital > mechanical — digital is more accurate and easier to read
- •Choose capacity 20% above your heaviest typical package (weight buffer)
- •Look for 0.1 oz resolution for accuracy; 0.01 oz for very small items
- •Hold/Zero button is essential — makes weighing easier
- •Plug-in powered > battery (batteries die during high-volume sessions)
- •Popular brands: Saga, Accuteck, Rubbermaid, FitSales
Frequently asked questions
What capacity shipping scale do I need?
For most ecommerce: 50 lb capacity. For heavy/oversized: 150-330 lb. Choose 20% above your heaviest typical package for accuracy buffer.
Are kitchen scales accurate enough?
Kitchen scales max out at 10-15 lbs and aren't designed for shipping. Postal scales have proper capacity and accuracy for packages.
How accurate does my scale need to be?
USPS requires accuracy to 0.1 oz for small packages. For 1+ lb packages, 0.1 lb accuracy is fine. Most $30-50 scales meet these standards.
Can I use my bathroom scale?
For weighing bigger items or checking your package + yourself (then subtracting), yes — but bathroom scales are less accurate than postal scales and can't zero properly.
Do I really need a shipping scale?
If you ship more than occasionally, yes — it pays for itself fast. Guessed weights cost money two ways: under-declaring triggers carrier adjustment fees weeks later, and over-declaring overpays on every label. A cheap digital scale that reads to the ounce eliminates both, and the carriers reconcile declared weight against their own scales regardless of your guess.
What capacity and precision should the scale have?
For parcels, a scale reading to 0.1 oz up to about 50 lb covers most e-commerce; heavier shippers want a 100+ lb platform. Precision matters most under a pound, where USPS ounce bands mean a fraction of an ounce crosses a price tier. If you sell light goods, prioritize fine resolution over huge capacity.
Postal scale vs kitchen scale — is there a difference?
A kitchen scale works for light parcels if it reads high enough and to the ounce, but dedicated shipping scales add useful features: hold function (for oversized items that block the display), higher capacity, and tare for packaging. For serious volume the shipping scale's ergonomics matter; for a few light packages a week, a decent kitchen scale genuinely suffices.
Should I weigh before or after packing?
After — always weigh the finished package. Carriers bill the shipped weight including box, void fill, tape, and label, and that can be a pound or more over the naked item. Weighing the packed parcel is the only number that matches what you'll actually be charged for.
