How to Calculate the Girth of a Box for Shipping?

Knowing how to get an accurate girth measurement when shipping boxes is of keen importance. By this, you can calculate the cost to ship, which is the correct packaging and can adhere to carrier regulations.

Girth, when we talk about parcel shipping, is basically the measurement around the thickest part of the parcel. Here in this guide, you’ll see how to measure girth of a box the right way and why it is significant.

Understanding Box Dimensions

Before you can measure girth you must find the dimensions of the box. A box typically has three dimensions: length, width, and height. The side that is faced in the upward position is considered the shortest side and known as while height, and the side that goes behind us is the longest side and known as length.

Measuring the Girth

Start by measuring around the thickest part of the box. Let’s reveal how to do this:

  1. Measure the Height: Take out a tape measure and measure the vertical dimension (from top to bottom) of the box.
  2. Measure the Width: Second, take the measurement from side-to-side across the box, if you look at the box from the front, that will often be the shorter side.
  3. Calculate the Girth: Doubling both width and height and adding these together. The formula looks like this:

Girth=2×(Width+Height)

Combining Girth and Length

Shipping carriers commonly use the length and girth to determine if a package is oversized or subject to additional handling fees. To find this combined measurement:

  1. Measure the Length: Determine the longest side of the box.
  2. Add Length and Girth: Use the formula Total Measurement=Length+GirthTotal.

This total gives you the size index that carriers use to categorize the shipping parcel.

Why Girth Matters?

  • Shipping Costs: Carriers often base their pricing on the size and weight of a package. Understanding how to measure the girth of your box helps predict shipping costs more accurately. A box that is particularly large or oddly shaped may cost more to send due to the increased space it occupies.
  • Carrier Restrictions: Most shipping companies have limits on the combined measurements of girth and length. Exceeding these limits can either disqualify you from using standard shipping services or significantly increase the cost.
  • Packing Efficiency: Measuring the girth gives you an accurate size to use for sizing your box. Large boxes can cause more material costs and extra shipping charges as dimensional weight pricing.
  • Avoid Delays: Having the boxes properly measured and appropriately sized declines delays in shipping. Packages that exceed the carrier’s size requirements may be held up, returned, or need to be re-packaged.

Conclusion

Measuring the girth of a box is such a simple process, yet it is so essential in the cost management of logistics and shipping that you can't make any mistakes with it. If you own a small business, you are a logistics manager, or even just want to send a gift to a loved one. Then, you know how to calculate the girth of the boxed package so that you are able to send it efficiently and affordably. As the above steps are so simple, anyone can learn this vital skill and prevent shipping disruptions and unnecessary costs.
