Why Is Proper Measuring of Box Important?

Before we dive deep into how to measure your boxes before you send them off to your customers, you need to know its importance. Being sure that you measure them right helps you against multiple issues, like:

  • You need to know the measurements of your boxes to determine the shipping costs
  • Space efficiency can help improve the transit of boxes, which you need to keep in mind.
  • You need to meet customs and import/export regulations, and that is where you need to keep the measurement in mind.
  • Also, you have to follow them for the safety of the goods that you are shipping
  • Measuring your boxes also helps in efficient inventory management
  • The use of right-sized boxes also helps with better customer satisfaction
  • You also have to be compliant with trade agreements that are required for shipment

When To Use Packaging Fill?

You can try packaging fill when you are looking to transport fragile products. Packaging fill is a type of material that you can add to a package to ensure it does not get damaged. It fills the space between a product packed and the box’s walls.

This way, you can get better protection by covering up the space and avoiding bumps during transit and transportation. So, here is when to use them:

  • If your box has empty spaces to bump around
  • It would work well for irregularly shaped items.
  • Also, it can help when you want to stack multiple items on each other.
  • If your products have delicate surfaces, you can use the fill.
  • Using them for electronics prone to issues with vibration and shocks can be helpful.
  • Always make sure to use them when the products inside are high-value.

How To Measure Box Dimensions For Shipping?

When it comes to measuring your equipment, you need to ensure you get it with the most appropriate tools.

Choose Your Tools Right

You can do this with the help of the following tools:

  • You need to carry a measuring tape to measure the dimensions of your box.
  • It should be long enough to provide you with the complete measurement.
  • Be sure that you have a straight ruler to ensure you get straight lines and to measure smaller dimensions.
  • Find a flat place to place the box. You can try using any flat surface.

Measure The Length

When it comes to the procedure of measuring the length, you should follow these steps:

  • Start by finding out the longest side of your box, which you can call the length of the box.
  • You can place the tape measure or a ruler on one side of the box corner. You can align it with the edge of the box.
  • Then, extend the tape measure or ruler to the opposite corner. Make sure to follow the contour of the box for the right measurement.
  • Next, you need to measure where it aligns with the opposite corner.
  • You can record the measurement in any unit.
  • Repeating the measurement will be a good practice to ensure you make things more accurate.
  • Once you have the measurement, you know the longest side of the box.
  • Also, record by rounding up the nearest whole inch or centimeter.
  • Ensure you include handles, flaps, or any other protruding elements.

Measure The Width

The next step will be to measure the width of your box:

  • Find out the width of your box; the side will be shorter.
  • Next, you should place the tape measure on the corner of your box at the edge.
  • Make sure you measure it by taking it to the opposite side.
  • Also, you should read the measurements to find the width.
  • Once done, measure the width in any units you want to use and make sure you repeat the process for better accuracy.

Measure The Height

In this step, you must measure with a ruler and ensure it is flat against one corner. Also, you should place the tape measure at the base of your box. Ensure you measure the vertical part of the box to get the exact measurement.

Then, you can measure the top of the box where the tape measure intersects with the edge of the box.

Measure The Girth

You can measure the circumference to ensure your boxes can be shipped best. For instance:

  • You can locate the shorter sides of the box, which you can call the width and height.
  • Make sure you add both the width and height together.
  • Next, multiply this sum by 2. This will allow you to measure both sides of your box.

Determine the Total Dimensions Of Your Boxes

Once you have all three different dimensions of your boxes, you can have the complete box.

  • Once you have the measurements, you can add them together.
  • One thing to keep in mind is that you measure these with the units you used for the initial measurements.
  • Ensure you add the measurement label to the boxes after completing the measurement.

Consider Irregular Shapes

When measuring your boxes, you must ensure you get all the measurements right. This goal can be challenging, so be aware of irregular shapes.

  • Ensure you do not forget to measure the parts that deviate from the shape.
  • You may have to measure your boxes’ widest width or length.
  • Make sure you measure the distance between these two points.
  • At the same time, you should record any irregularities in the boxes to ensure better results.
  • You should also know the perimeter of these irregular shapes.
  • Once you have all the measurements you have to add labels to indicate the right measurements for you.
