Step-by-Step Guide
Unlocking the Art of Package Dimension Measurement

Discover the Length: Identify the longest side with a flap, measure from end to end, and round off to the nearest inch or centimeter.

Unveil the Width: Measure across the side with a flap, rounding to the nearest inch or centimeter.

Ascertain the Height: Measure the unflapped side, rounding to the nearest inch or centimeter.
Pro Tip: For irregular shapes, measure like a rectangular box, capturing extremes for length, width, and height.
Unveiling the Secrets of Volume & Dimensional Weight Calculation

Unlock the Mystery of Volume: Multiply the box's dimensions to unveil its volume, representing the inner space.

Crack the Code of Dimensional Weight: Divide the volume by the carrier's divisor to uncover its dimensional weight, a crucial factor in shipping costs.

Weigh Your Package: Use a postage scale to determine the actual weight of your package, ensuring accurate shipping cost estimates.
Pro Tip: Invest in a postage scale for convenience and cost-effectiveness in shipping endeavors. Quality scales are available online starting from $20-30.

Optimize Your Costs: Compare your package’s actual weight to its dimensional weight to determine your shipping price.
Unlocking Package Girth and Total Size

Discover the Girth: Double the width and height, then add them to find the girth, the measurement around the thickest part of the box.

Calculate Total Package Size: Add the length and girth to obtain the total package size for shipping, ensuring compliance with size restrictions.
Handy Tips
- For regular slotted cartons (RSCs), both horizontal surfaces are identical, allowing flexibility in choosing the top or bottom.
- If using a specialty box, look for visual cues like logos and text to determine its correct orientation.
- Each shipping service has unique guidelines and restrictions regarding size and weight. Compare pricing policies to find the best fit for your budget.
