1. What is a UPS Box Size Calculator?

Definition: This calculator estimates the volume of a shipping box based on its length, width, and height measurements.

Purpose: It helps shippers determine package volume for UPS shipments, which is important for pricing and space optimization.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V \) — Volume of the box (cubic inches)
• \( L \) — Length of the box (inches)
• \( W \) — Width of the box (inches)
• \( H \) — Height of the box (inches)

Explanation: The three dimensions are multiplied together to calculate the total volume of the rectangular box.

3. Importance of Box Volume Calculation

Details: UPS uses dimensional weight pricing, which considers both actual weight and package volume. Accurate volume calculation helps estimate shipping costs.

4. Using the Calculator

Tips: Measure the inside dimensions of your box in inches. Enter length, width, and height. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Should I measure inside or outside dimensions?
A: For shipping calculations, always use the inside dimensions of the box.

Q2: How do I convert to cubic feet?
A: Divide cubic inches by 1728 (12×12×12) to get cubic feet.

Q3: What's the maximum size for UPS packages?
A: UPS has a maximum size of 165 inches in length and girth combined.

Q4: Does this account for dimensional weight?
A: No, this calculates actual volume. Compare with dimensional weight (L×W×H/139 for UPS) to determine which is used for pricing.

Q5: Can I use centimeters instead?
A: Yes, but be consistent (all measurements in cm) and note the result will be in cubic centimeters.
