Packages and shipment weights

When you're fulfilling an order, you need to choose a package that matches the package type that you want to use.

You cansave your preferred package typeson theShipping and deliverysettings page or on an order'sFulfillmentpage in your Shopify admin. Most carriers charge by size and weight, so it’s important to keep your packaging small. When you're ready to buy a shipping label for your shipment, the store default package or asuggested packagewill be pre-selected for you, which you can change if you want to use a different saved package.

You can use the following package types to ship your products with Shopify Shipping labels.

Package shipment limits are set by the carrier. Girth is the measurement around the middle of the package, and is calculated as 2x width + 2x height. Length is measured on the longest side of the package. To learn more about maximum package requirements for specific carriers, refer toShopify Shipping carriers.

Soft pack

A padded envelope, bubble mailer, or plastic (Tyvek or Poly) sleeve. Packages thicker than 3/4 inches don't qualify for USPS First Class Mail rates.

Envelope

A large, flat envelope no thicker than 3/4 inches.

Flat rate

Flat rate packaging is offered by most carriers. These packages are not priced by size or weight, but rather a pre-determined package size and shipping speed that you've chosen from your carrier's available options.

If your store is based in the United States, then you can use USPS flat rate packaging. You can alsorequest a free USPS shipping kitto get you started.

Carrier packages are shipping packages available from the carrier with markings indicating that they qualify for special rates or services. These packages can be acquired from the carriers directly. If you use a package that matches the dimensions, but the package isn't provided by the carrier, then your package doesn't qualify for special rates or services.

After you add weights to your products, make sure that your packaging weights and dimensions are also accurate. Most carrier-provided packaging displays dimensions on the box. Learn more aboutadding a package.

Dimensional weight

Your default package dimensions are sent to your shipping carrier along with your order's weight to calculate shipping rates for your customer. Dimensional weight is determined by the carrier based on the height, width, and depth of your packages. Dimensional weight applies to some shipping services when a package's total length x width x height exceeds 1 cubic foot (1728 cubic inches).

If your dimensional weight is larger than your order's weight, then your customer is charged for the dimensional weight of their order. If you think that the generated rates are too high or too low, then you canadjust your calculated ratesto increase or decrease your shipping rates as needed.

Dimensional weight calculations vary between carriers. Consult the carrier you're using for details about their dimensional weight policies.

The following carriers have dimensional weight policies:
