The Linear Inches Calculator is a practical, travel-friendly tool designed to help you instantly calculate the total dimensions of a bag or package using the linear inch formula. It’s especially helpful for anyone preparing for a flight, shipping a parcel, or trying to avoid oversized baggage fees.
Airlines and shipping companies often define size limits in terms of linear inches—which is simply the sum of a bag’s length, width, and height. For example, most airlines allow checked luggage up to 62 linear inches and carry-ons up to 45 linear inches. This tool helps you verify if your luggage or package meets those size requirements without needing a calculator or second-guessing measurements.
Who This Tool Helps:
- Travelers checking carry-on and checked baggage compliance
- Backpackers comparing gear sizes
- Online sellers preparing parcels for USPS, FedEx, or UPS
- Parents packing kids' luggage for trips
- Shipping departments that need fast dimension checks
Example Scenario
You're packing a suitcase for vacation. It measures:
- Length: 30 inches
- Width: 20 inches
- Height: 10 inches
The calculator adds them: 30 + 20 + 10 = 60 linear inches
Great news—it’s within the 62-inch airline limit!
