One wrong measurement can turn a $10 shipment into a $40 one. Dimensional weight pricing means box size matters just as much as what's inside it.\u00a0\u00a0<\/p>\n

With the rise of online shopping and subscription services, more businesses than ever rely on UPS, USPS, and FedEx to deliver products. If you ship packages or fulfill online orders, choosing the right box sizes and weight limits is essential for safe, efficient, and cost-effective delivery. This guide covers the key requirements for UPS, USPS, and FedEx so you know exactly what rules to follow before you ship.<\/p>\n<\/div>

\nHow to Measure Packaging? \n<\/h2>
\n

USPS, UPS, and FedEx usually measure rectangular packages using the same three dimensions.<\/span>\u00a0<\/span><\/p>\n

    \n
  • Length is the longest side of the package.\u00a0<\/li>\n
  • Width is the side perpendicular to the length.\u00a0<\/li>\n
  • Height is the last dimension.\u00a0<\/li>\n<\/ul>\n<\/div>
    \n

    Couriers also measure the box\u2019s <\/span>girth<\/span><\/b>, which is the distance around the thickest part of the package. For a standard rectangular box, girth is calculated as <\/span>(2 x width) + (2 x height)<\/span><\/b>.<\/span>\u00a0<\/span><\/p>\n

    These measurements help determine other important shipping values. One common value is <\/span>length + girth<\/span><\/b>, which determines the <\/span>package\u2019s total size<\/span><\/b>.<\/span>\u00a0<\/span><\/p>\n

    Carriers also look at the package\u2019s weight, usually measured in pounds (lbs). Since shipping rules and costs depend on both size and weight, it\u2019s important to record both so you can check if your package meets the carrier\u2019s limits.<\/span>\u00a0<\/span><\/p>\n<\/div>

    \nWhat About Non-Rectangular Packages?\n<\/h2>
    \n

    Irregular or oddly shaped packages need <\/span>special care<\/span> because standard<\/span> measurements are for rectangular boxes. Instead of measuring only the product, carriers may measure the space the package takes up or the size of a box that could hold it.<\/span><\/p>\n<\/div>

    \nWhat are the\u202fPackaging Requirements for Couriers? \n<\/h2>
    \n

    Most courier companies have size and weight limits to make packages easier to handle, use transport space efficiently, and keep items safe during shipping. These rules can also help set fair shipping prices. Each company has its own guidelines; <\/span>here\u2019s<\/span> what you can expect from USPS, UPS, and FedEx.<\/span><\/span>\u00a0<\/span><\/p>\n<\/div>

    \nShipping Requirements for UPS\n<\/h2>
    \n

    UPS Shipping Dimensions:<\/span><\/b>\u00a0<\/span><\/p>\n

    UPS allows packages up to <\/span>108\u201d<\/span><\/b> long, with a combined length-and-girth limit of <\/span>165\u201d<\/span><\/b>. When measuring, UPS rounds each dimension up to the next whole inch. For example, if a side is between 1.01\u201d and 1.99\u201d, it counts as 2\u201d.<\/span>\u00a0<\/span><\/p>\n

    UPS Weight Requirements:<\/span><\/b>\u00a0<\/span>\u00a0<\/span><\/p>\n

    UPS accepts packages weighing up to <\/span>150 lbs. <\/span><\/b>However, packages over <\/span>70 lbs<\/span><\/b> come with extra charges and require a <\/span>\u201cHeavy\u201d package sticker<\/span><\/b> for safe handling. If a package weighs more than 150 lbs, UPS usually ships it as <\/span>freight<\/span><\/b> instead of a regular package.<\/span>\u00a0<\/span><\/p>\n<\/div>

    \n

    Shipping Requirements for U<\/span>S<\/span>PS<\/span><\/h3>\n<\/div>
    \n

    USPS Shipping Dimensions:<\/span><\/b>\u00a0<\/span>\u00a0<\/span><\/p>\n

    For most domestic shipments, USPS packages can have a <\/span>combined length and girth of up to 108\". <\/span><\/b>With USPS Ground Advantage, you can send packages <\/span>up to 130\", but anything over 108\" <\/span><\/b>may have an extra oversized fee.<\/span>\u00a0<\/span><\/p>\n

    USPS packages <\/span>larger than 130\" <\/span><\/b>are considered <\/span>nonmailable<\/span><\/b> and may incur extra penalties.<\/span>\u00a0<\/span><\/p>\n

    For international shipping, size limits depend on the destination. Use the <\/span>USPS Postage Calculator<\/span><\/b> to find the size limit and regulations for each country.<\/span>\u00a0<\/span><\/p>\n

    USPS Weight Requirements:<\/span><\/b>\u00a0<\/span>\u00a0<\/span><\/p>\n

    Most domestic USPS packages <\/span>cannot weigh more than 70 lbs. <\/span><\/b>For international shipments, weight limits vary by country and mail service.<\/span>\u00a0<\/span><\/p>\n

    You can use the <\/span>USPS Postage Calculator<\/span><\/b> to check weight and size limits and get a postage estimate.<\/span>\u00a0<\/span><\/p>\n

    If a domestic package weighs more than <\/span>70 lbs,<\/span><\/b> USPS considers it <\/span>nonmailable <\/span><\/b>and may charge an extra fee. The sender or recipient will need to pick up the package instead of being delivered as usual.<\/span><\/p>\n<\/div>

    \n

    Shipping Requirements for FedEx<\/span><\/span><\/h3>\n<\/div>
    \n

    FedEx Shipping Dimensions:<\/span><\/b>\u00a0<\/span>\u00a0<\/span><\/p>\n

    With FedEx Ground and Home Delivery, you can ship packages<\/span> up to 119\" long<\/span><\/b> and <\/span>up to 165\" when you add length and girth<\/span><\/b> together. International shipments usually have smaller size limits.\u00a0<\/span>\u00a0<\/span><\/p>\n

    Some services only allow up to <\/span>108\" in length<\/span><\/b> and <\/span>130\" in combined length and girth<\/span><\/b>. Always check the specific rules for your FedEx service and destination before sending your package.<\/span>\u00a0<\/span><\/p>\n

    FedEx Weight Requirements:<\/span><\/b>\u00a0<\/span>\u00a0<\/span><\/p>\n

    Standard FedEx packages, including Ground and Home Delivery, can weigh up to <\/span>150 lbs.<\/span><\/b> However, you must use a yellow-and-black safety-weight label if your package weighs more than <\/span>75 lbs.<\/span><\/b>\u00a0<\/span>\u00a0<\/span><\/p>\n

    For shipments <\/span>over 150 lbs,<\/span><\/b> you must use <\/span>FedEx Express Freight services. <\/span><\/b>Freight weight limits depend on the service and how you pack your shipment.<\/span><\/p>\n<\/div>
