With your Ship.com account you can use your own boxes, envelopes, or poly-mailers to get your orders to your customers. Make sure that any packaging that you use does not have any previous labels or markings on the package. You'll also need to enter your package type along with the dimensions to guarantee that you are getting an accurate postage quote for your package. #### Packaging Type You can choose from multiple packaging types when entering your package details when purchasing a shipping label. There are specific presets to choose from that will automatically enter the package details. If you are shipping with your own package then you'll want to choose either 'Other Package Size' if it is a box or 'Soft Pack' if the package is rigid/flexible with outer material made of plastic, paper, fabric, etc. ![chrome\_EqLBYCFvLY](https://help.ship.com/hs-fs/hubfs/chrome_EqLBYCFvLY.png?width=521&height=239&name=chrome_EqLBYCFvLY.png) There are other preset types you can choose from that will automatically enter the dimensions of the package for you. [**Polymailer Preset Options**](https://app.ship.com/supplies) include some of the most commonly used polymailers when shipping. **[Priority Mail Tyvex Envelope](https://store.usps.com/store/product/priority-mail-tyvek-envelopes-P_EP_14)** and **[Priority Shoe Box](https://store.usps.com/store/product/priority-mail-shoe-box-P_0_SHOEBOX)** are available free from the USPS and you must use a Priority shipping option when using these boxes. You can also choose from many of the most common **[UPS packaging options](https://www.ups.com/us/en/shipping/order-supplies.page)** to be used for any UPS postage options. You cannot use any of USPS's **Flat Rate** packaging when shipping with a custom package. We generate separate prices for flat rate package.  #### Packaging Weight & Dimensions You must have an **accurate weight** when shipping to ensure you do not receive [an adjustment](https://help.ship.com/knowledge/why-did-i-get-an-additional-charge-for-my-usps-package?hsLang=en) on your postage after shipping. You can enter the weight in pounds and ounces when shipping. We recommend that you use an accurate weight to ensure the correct shipping options are shown for your order. You can find [affordable postal scales online](http://www.amazon.com/dp/B00KYA0RC2/ref=nosim?tag=shipdotcom-20) to make sure you have an accurate weight!  When entering the **dimensions measure** the package using inches and round up to the nearest half inch. We recommend entering all three dimensions when shipping either parcels or soft packs to ensure that your cubic pricing is calculated properly. ### Other Shipping Options You can customize each package with various shipping options to ensure the delivery meets your specific needs. To choose a quick delivery just use one our the [express shipping options](https://help.ship.com/knowledge/can-i-purchase-express-shipping-for-a-package?hsLang=en)displayed after entering your package information. To add signature, Saturday delivery, or Declared value then use the Additional options in the upper right corner while purchasing your shipping label. ![chrome\_atp5asPS6M](https://help.ship.com/hs-fs/hubfs/chrome_atp5asPS6M.png?width=688&height=401&name=chrome_atp5asPS6M.png) **To explore other postal options, visit our helpful [postage breakdown](https://help.ship.com/knowledge/which-couriers-are-available-through-ship.com?hsLang=en). ** - [Getting Started Guide](https://help.ship.com/knowledge/getting-started-guide?hsLang=en#main-content) - [Rewards - Customer Loyalty](https://help.ship.com/knowledge/getting-started-guide?hsLang=en#rewards-customer-loyalty) - [Connect - Customer Communications](https://help.ship.com/knowledge/getting-started-guide?hsLang=en#connect-customer-communications) - [Tracking, Invoicing, and More](https://help.ship.com/knowledge/getting-started-guide?hsLang=en#tracking-invoicing-and-more) - [Tutorials](https://help.ship.com/knowledge/tutorials?hsLang=en#main-content) - [Connect Your Store](https://help.ship.com/knowledge/tutorials?hsLang=en#connect-your-store) - [Use Your Account](https://help.ship.com/knowledge/tutorials?hsLang=en#use-your-account) - [Pink Zebra Video Tutorials](https://help.ship.com/knowledge/pink-zebra-video-tutorials?hsLang=en#main-content) - [How to Ship Your First Pink Zebra Order](https://help.ship.com/knowledge/pink-zebra-video-tutorials?hsLang=en#how-to-ship-your-first-pink-zebra-order) - [Connect Your Payment Platform](https://help.ship.com/knowledge/pink-zebra-video-tutorials?hsLang=en#connect-your-payment-platform) - [Batch Shipping Made Simple](https://help.ship.com/knowledge/pink-zebra-video-tutorials?hsLang=en#batch-shipping-made-simple) - [Schedule Free USPS Pickup Using Ship.com](https://help.ship.com/knowledge/pink-zebra-video-tutorials?hsLang=en#schedule-free-usps-pickup-using-ship-com) - [How to Add Insurance](https://help.ship.com/knowledge/pink-zebra-video-tutorials?hsLang=en#how-to-add-insurance) - [How to Cancel a Label, Process Refunds](https://help.ship.com/knowledge/pink-zebra-video-tutorials?hsLang=en#how-to-cancel-a-label-process-refunds) - [Email Marketing To Grow Your Pink Zebra Business](https://help.ship.com/knowledge/pink-zebra-video-tutorials?hsLang=en#email-marketing-to-grow-your-pink-zebra-business) - [Build Customer Loyalty With Rewards Program](https://help.ship.com/knowledge/pink-zebra-video-tutorials?hsLang=en#build-customer-loyalty-with-rewards-program) - [Buy Shipping Supplies Efficiently](https://help.ship.com/knowledge/pink-zebra-video-tutorials?hsLang=en#buy-shipping-supplies-efficiently) - [F.A.Q](https://help.ship.com/knowledge/f-a-q?hsLang=en#main-content) - [Shipping and Tracking](https://help.ship.com/knowledge/f-a-q?hsLang=en#shipping-and-tracking) - [Subscription and Billing](https://help.ship.com/knowledge/f-a-q?hsLang=en#subscription-and-billing) - [Customers and Orders](https://help.ship.com/knowledge/f-a-q?hsLang=en#customers-and-orders) [![Logo with tagline.jpg](https://help.ship.com/hubfs/Logo%20with%20tagline.jpg.svg "Logo with tagline.jpg")](https://ship.com) Ship.com Help Center Copyright © 2026, Ship.com
