Linear Inches Formula:
| From: | To: |
Linear inches represent the total sum of the three dimensions (length, width, and height) of an object. This measurement is commonly used in shipping and travel industries to determine size restrictions for luggage and packages.
The calculator uses the linear inches formula:
Where:
Explanation: This simple calculation provides a single number that represents the overall size of an object, which is particularly useful for determining if an item meets size restrictions for airlines or shipping carriers.
Details: Many airlines and shipping companies use linear inches to enforce size limitations on luggage and packages. Understanding this measurement helps ensure compliance with regulations and avoid additional fees.
Tips: Measure your item's dimensions in inches, enter each value in the corresponding field, and click calculate. All values must be positive numbers.
Q1: How do I measure linear inches for luggage?
A: Measure the length, width, and height of your luggage in inches and add them together. Most airlines have specific linear inch limits for checked and carry-on baggage.
Q2: What is a typical linear inch limit for airline luggage?
A: This varies by airline, but common limits are 62 linear inches for checked baggage and 45 linear inches for carry-on luggage. Always check with your specific airline.
Q3: Does the order of dimensions matter in the calculation?
A: No, the calculation is commutative - length + width + height will always equal width + height + length. The sum remains the same regardless of order.
Q4: Can I use this calculator for metric measurements?
A: This calculator is designed for inches. If you have measurements in centimeters, you can convert them to inches first (1 inch = 2.54 cm) or use a metric-specific calculator.
Q5: Are there items where linear inches don't apply well?
A: Linear inches work best for rectangular objects. For irregularly shaped items, you should measure at the widest points of each dimension.
