Packages and shipment weights
When you're fulfilling an order, you need to choose a package that matches the type that you want to use:
You can save your preferred package types on the Shipping settings page or on an order's Fulfillment page 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, you can choose which one of your saved packages you want to use.
Supported package types
You can use the following package types to ship your products with Shopify Shipping labels:
A regular package. The total of the length, width, and height can't be above 84 inches.
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.
A large, flat envelope no thicker than 3/4 inches.
Flat rate packaging is supplied by your carrier. Its shipping cost is not determined by the weight of your shipment.
If your store is based in Canada, then visit Canada Post's packaging best practices guide for more packaging tips.
Unsupported package types
You can't use the following package types to ship your products with Shopify Shipping labels:
A flat envelope or letter thinner than 1/4 inch.
A package whose total dimensions (to total of the package's length, width, and height) are greater than 84 inches.
A non-rectangular package.
Add a package type
You can save the dimensions and weights of your preferred package types on the Shipping settings page in your Shopify admin. If you enter dimensions and weights for your packages, then your calculated shipping rates will be more accurate.
- From your Shopify admin, go to Settings > Shipping.
In the Packages section, click Add package:
In the dialog, enter the required information about the package type: Some mail types have restrictions on the size of the packages that you can use to ship your products. A notice about applicable size restrictions will appear on the dialog when you create a new package type.
Free packaging materials
Many carriers offer free packaging to use with specific shipping rate. Although there is no cost for the packaging, you might need to create a free account with the carrier so that they can send the packaging to you. The following Shopify Shipping carriers offer free packaging:
USPS flat rate packaging
Flat rate pricing is determined by the packaging that you choose as long as the package weighs less than 70 lb. You are charged for the price of the flat rate box or envelope and not the weight of the package or the distance that it has to travel.

Common product weights
You need to include accurate weights for your products so that your customers are charged the correct amount for shipping. Accurate product weights also ensure that you're charged correctly for the USPS, DHL Express, and Canada Post labels you purchase through Shopify.
Until you get a scale for accurate measurements, you can use the following general guidelines:
|Less than 8 oz||Light items such as jewelry, watches, phone cases, light clothing (for example, a scarf), accessories, socks, or intimates. These items can be shipped in a poly mailer or bubble mailer.|
|8-16 oz||Most clothing items (for example, a T-shirt or blouse), or a watch in its case. Most of these items can be shipped in a poly mailer, bubble mailer, or a small box.|
|1-2 lb||Heavier clothing items (for example, a jacket or dress pants), a cell phone in its box, sneakers, or light items that need to ship in a small box.|
|2-3 lb||Jeans or small electronics (for example, a small camera). These items can be shipped in a small box.|
|3-4 lb||A set of children's play blocks, a few paperback books, men's shoes, or a large camera with accessories. These items can be shipped in a small box.|
|4-5 lb||Medium to large sized items (for example, a full set of sheets, or a puzzle box). These items can be shipped in a medium box.|
|5-6 lb||Individual cookware, small tabletop appliances, or boxed board games. These items can be shipped in a medium box, though some larger books might fit better in another type of packaging (for example, a bubble mailer).|
|6-7 lb||Large toy (for example, a doll), work boots, or small sporting equipment. These items can be shipped in a medium box.|
|7-8 lb||Cookware sets, or medium tabletop appliances (for example, a toaster). These items can be shipped in medium or large boxes.|
|8-9 lb||Large radios, or DVD players. These items can be shipped in a large box.|
|9-10 lb||Sets of items (for example, several books or pieces of clothing), or home decor. These items can be shipped in medium or large boxes, though some larger books might fit better in another type of packaging (for example, a bubble mailer).|
After you've added weights to your products, make sure that your packaging weights and dimensions are also accurate. Most carrier-provided packaging comes with dimensions advertised on the box. To learn more about adding a package type, see Initial setup
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 can adjust your calculated rates to 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.
