Shipping Scale

Also known as: Postal Scale, Package Scale, Digital Shipping Scale

Definition

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

Types of Shipping Scales

By Capacity

Type Capacity Best For
Light duty 0-35 lbs Letters, small packages
Medium duty 0-75 lbs Most e-commerce
Heavy duty 0-150 lbs Large packages, pallets
Industrial 150+ lbs Freight, heavy items

By Connectivity

Connection Pros Cons
USB Reliable, direct Wired connection
Bluetooth Wireless Battery, pairing issues
Serial (RS-232) Industrial standard Older technology
WiFi Network connected Setup complexity

Using a Shipping Scale

Basic Weighing

  1. Place scale on flat, stable surface
  2. Turn on and let calibrate
  3. Press TARE/ZERO
  4. Place package on scale
  5. Wait for stable reading
  6. 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
         Pre-weighing materials
         Accuracy with packaging

Scale Accuracy

Readability vs. Capacity

Capacity Typical Readability
10 lbs 0.1 oz
25 lbs 0.2 oz
75 lbs 0.5 oz
150 lbs 1.0 oz

Accuracy Considerations

  • Round up to nearest carrier increment
  • Calibrate periodically
  • Keep scale clean
  • Level surface critical
  • Temperature affects some scales

Scale Integration

Compatible Software

Most shipping platforms work with USB-connected scales. With I’d Ship That, you simply enter the weight from your scale—no special integration needed.

Other platforms with direct scale integration:

  • ShipStation (select models)
  • Shippo
  • Stamps.com
  • Endicia
  • Pirate Ship

Setup Process

  1. Install scale drivers
  2. Connect scale (USB typically)
  3. Configure in software settings
  4. Test weight capture
  5. Verify accuracy

Choosing a Shipping Scale

Evaluation Criteria

  1. Capacity - Max package weight
  2. Precision - Readability needed
  3. Platform size - Fits your packages
  4. Connectivity - Software compatible
  5. Power - Battery vs. AC
  6. Durability - Volume of use

Size Guidelines

Daily Volume Recommended
1-20 packages Basic USB scale
20-100 packages Mid-range connected
100+ packages Industrial grade

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

Common Scale Issues

Problem Cause Solution
Drifting weight Not level Level surface
Won’t zero Overload Remove excess weight
Erratic readings Dirty platform Clean scale
Won’t connect Driver issue Reinstall driver
Inaccurate Out of calibration Recalibrate
