The dimensions of a box are something beyond numbers; they`re the groundwork of an item`s safety, cost-effectiveness, and overall display. While calculating a box dimension could appear as a straightforward errand, guaranteeing exactness is fundamental, particularly regarding custom packaging. We should explore the subtleties of measuring box dimensions and why they are significant for your business.

Measure the Box Size Correctly

Recollect the well-known saying, "Measure two times and cut once"? A similar rule executes to box dimensions. Before ordering custom boxes or making bulk buys, you must guarantee you select the right size. Just assessing or eye-balling box dimensions for shipping wouldn`t do the trick. Set aside some margin to measure precisely, keeping away from expensive errors.

Have Knowledge About Box Dimensions

There are two significant measurements regarding box dimensions: the inside and outside measurements. For instance, a typical 16″x12″x12″ box addresses its inside measurements. Be that as it may, a similar box will have marginally bigger external measurements, identical to 16 3/8″ x 12 3/8″ x 12 5/8″. Understanding the distinction between inside and outside box dimensions is indispensable to avoid fit issues. Before you even contemplate box manufacturing, getting a handle on the three essential elements of any box is fundamental: length, width, and volume. Here is a fast breakdown:


The length of a custom box is ordinarily its longest side when seen from the top of the opening. It fills in as the essential aspect that frequently decides the direction of the packaging box. Generally speaking, the length relates to the horizontal dimension of the item inside, particularly for prolonged things. While measuring the length, it`s vital to start from one end and broaden the measuring tape straight across to the far edge, guaranteeing it`s tight and level. The length is vital in deciding the direction of the box and frequently relates to the essential dimension of the item inside.


The width of a shipping box is the more limited side while checking the top out. It`s opposite to the length and frequently decides the front face of the box, particularly in product display packaging. While measuring the width, guarantee that the measuring tape ranges from one side to the next with practically no leeway. It`s additionally important that the width can differ because of the design of the shipping box, particularly assuming it has novel shapes or cutouts. The width is crucial for display purposes and can impact how an item is exhibited on retail shelves.

Height or Depth

Depth, reciprocally alluded to as height, is the side opposite of the length and width. It decides how tall the shipping box stands. The depth is a basic measurement for stacked items or needing to fit inside unambiguous storage limitations. On account of a shoebox, for instance, the depth would oblige the height of the shoe boxes stacked on top of one another. Measuring the depth requires an upward box measurement from the foundation of the box to its highest point. For packages with covers or folds, measure the depth, including the folds, as they diminish the usable inside box dimensions. Depth is critical for understanding how items will be stacked or stored, guaranteeing productive utilization of space.


Whenever you have three box dimensions, now is the right time to work out the volume. This isn`t just about how much space is inside the box; it`s tied in with streamlining material use, diminishing expenses, and guaranteeing the primary uprightness of your custom packaging. To work out the volume, utilize the basic equation: Volume = length x width x depth. At the same time, it`s conceivable to calculate volume without knowing which measurement is which; keeping them directly is a decent practice to avoid disarray.

Why Volume Matters for Product Storage

The volume of a shipping box decides how cozily an item will fit inside. A box with the right volume guarantees the item is safe and shown ideally and stylishly when unpacked. Realizing the volume assists in choosing the right amount of defensive packaging material, lessening waste and expenses. Misjudging volume can prompt pointless material expenses while underrating can make one think twice about an item`s security. Transporters frequently charge because of the bundles` volume (or layered weight). A box with enhanced volume can prompt significant savings in delivery costs. Also, understanding volume helps with proficient warehousing, taking into consideration better stacking and storage. IMH Packaging can help you figure out professional warehousing and how to calculate box dimensions for shipping.

The Significance of Internal Box Dimensions

This distinction is critical for guaranteeing that your item fits cozily and safely inside its custom packaging. Measuring box sizes for shipping could appear to be more straightforward. However, it doesn`t represent the thickness of the box material. This can be particularly deceptive with corrugated boxes, where the fluting adds millimetres to each outer box measurement.

Measuring box dimensions probably won`t be advanced science. However, it requires attention to detail. Whether you`re working out a volume or settling on inside and outside measurements, exactness is significant. With these bits of knowledge, you`re exceptional at handling any packaging project. Moreover, if you need expert guidance, recall that expert assistance is only a click away. IMH Packaging couldn`t want anything more than to assist with bringing your packaging ideas to life.

Box Size Terminology

Inventories and sites, for the most part, allude to box sizes utilizing inside dimensions. Measurements are recorded in length, width, and height (L x W x H). While measuring for a custom box, measure accuracy by measuring the specific cubic size to the nearest 1/tenth of an inch. Utilize a ruler or measuring tape to double-check your box measurements.

Have Knowledge About Shipping Costs

Deciding the outside measurements of your shipping box is basic for working out transportation costs. While transportation costs could shift across administrations and transporters, you can assess costs based on their particular box size rules. FedEx and USPS offer thorough rules for delivery box sizes, assisting you with expecting prices.

For bulk shipments, the outside measurements will help you assess the number of boxes that can fit on a pallet productively. The exact measurement of box dimensions is fundamental for fruitful delivery and packaging endeavors.

Measuring Box Dimensions

For standard rectangular or square boxes, measuring the length, width, and height is straightforward:

Length: Measure the longest side of the box from one corner to the opposite corner. Ensure the measuring tape is straight and aligned with the edges.

Width: Measure the shorter side of the box, again from one corner to the opposite corner.

Height: Measure the distance from the bottom of the box to the top. Ensure the measuring tape is perpendicular to the length and width measurements.

Measure Irregularly Shaped Boxes

If your box is not a perfect rectangle or square, you may need to measure additional dimensions:

Diameter: For cylindrical or round objects, measure the diameter (the distance across the widest part). If the thing is long, also measure the length.

Girth: In some cases, you`ll need to measure the girth, which is the total distance around the box. To measure girth, wrap the measuring tape around the widest part of the box.

Record the Measurements

After measuring, record the dimensions as follows: Length x width x height (in that order). For example, if your box measures 12 inches in length, 8 inches in width, and 6 inches in height, the recorded dimensions would be 12" x 8" x 6".

Measure the Weight

Use a scale to weigh the box with its contents. If you`re shipping multiple packages, weigh each one individually. Record the weight accurately, including any packaging materials that add to the total weight.

Packaging Considerations You Need to Keep in Mind

In addition to measuring box dimensions, consider the following packaging aspects:

Packaging Materials: Ensure the box is adequately padded to protect the contents during transit. Bubble wrap, packing peanuts, or crumpled paper can help safeguard fragile items.

Box Strength: Choose a box that can support the weight of its contents. Corrugated cardboard boxes are a popular choice for their durability.

Sealing: Use quality packaging tape to seal the box securely. Ensure all seams are sealed to prevent items from falling out.

Labelling: Label the box with the recipient`s address and contact information. It`s also a good practice to include a return address.

Fragile Items: Mark boxes containing fragile items to alert handlers to exercise caution.

Have Complete Knowledge of Shipping Carrier Guidelines

Different shipping carriers may have varying guidelines for box dimensions and weight limits. In addition, always check the specific requirements of your chosen carrier, as failure to comply can result in delays, additional fees, or even returned shipments. Some common guidelines include:

Maximum Weight: Most carriers have weight limits for each package, ranging from 50 to 70 pounds (22.7 to 31.8 kilograms).

Maximum Dimensions: Carriers may specify maximum dimensions for a package. These can vary, but a common guideline is a full length and girth (combined) of 108 inches.

Oversized Packages: If your package exceeds the carrier`s maximum dimensions, it may be considered large, incurring additional fees.

Dimensional Weight: Some carriers calculate shipping costs based on dimensional weight rather than the actual weight. This means that larger, lighter packages can be more expensive to ship.

Tips for Efficient Shipping

To streamline your shipping process and ensure efficiency, consider the following tips:

Standardized Box Sizes: Use standard box sizes to optimize packing and save on shipping costs.

Remove Unnecessary Space: Use packing materials to fill empty spaces within the box. This minimizes movement during transit and prevents damage.

Weight Distribution: Distribute heavy items evenly within the box to prevent it from becoming top-heavy or unbalanced.

Labeling and Documentation: Label your boxes, including complete addresses and contact information. Moreover, keep records of shipments, tracking numbers, and receipts.

International Shipping: If shipping internationally, be aware of customs regulations and required documentation, such as customs forms and invoices.
