A shipping scale is a specialized weighing device used to determine the weight of packages for accurate shipping cost calculation. Modern shipping scales connect to computers and integrate with shipping software for seamless label generation.
Why Shipping Scales Matter
Accuracy Importance
- Weight determines shipping cost
- Inaccurate weights cause problems:
- Underweight: Carrier adjustments, fees
- Overweight: Paying more than necessary
- USPS: Postage due to recipient
Cost Impact
Example: Package actually weighs 5.2 lbs
Estimated at 5 lbs: $12.50
Actual charge after weigh: $14.75
Adjustment fee: $3.00
Total extra cost: $5.25 per package

Using a Shipping Scale
Basic Weighing
- Place scale on flat, stable surface
- Turn on and let calibrate
- Press TARE/ZERO
- Place package on scale
- Wait for stable reading
- Record weight
With Shipping Software
Workflow:
1. Create shipment in software
2. Place package on scale
3. Software reads weight automatically
4. Weight populates in form
5. Generate label with correct weight
Tare Function
Using tare:
1. Place empty box on scale
2. Press TARE (display shows 0.00)
3. Add contents
4. Display shows contents weight only
Use for: Consistent box weights

Scale Maintenance
Regular Care
- Keep platform clean
- Check calibration monthly
- Protect from drops
- Don’t exceed capacity
- Replace batteries proactively
Calibration
Calibration check:
1. Use known weight (certified)
2. Place on scale
3. Compare reading
4. If off, recalibrate per manual
5. Document calibration date
