FedEx Express Box Sizes
FedEx Small Box (12.25x10.9x1.5"): Documents, small items, thin products. Very flat profile - good for items that can lay flat.
FedEx Medium Box (13.25x11.5x2.38"): Books, software, slightly bulkier items. Most versatile size for standard shipments.
FedEx Large Box (17.5x12.25x3"): Larger flat items, multiple products, clothing. Wide footprint but limited depth.
FedEx Extra Large Box (11.88x11x10.75"): Cube-shaped for bulky items. Only box with significant depth. Good for 3D items.
FedEx One Rate Explained
What is One Rate: Flat-rate pricing based on box size and delivery speed, regardless of weight (up to 50 lbs) or destination. Similar to USPS Flat Rate but with FedEx speed options.
Speed options: One Rate works with FedEx Express Saver (3 days), 2Day, 2Day AM, Standard Overnight, Priority Overnight, and First Overnight services.
When to use: One Rate saves money on heavy items going long distances with Express service. For Ground shipping, standard calculated rates usually win.
FedEx Ground Packaging
Your own packaging: Unlike Express, FedEx Ground does not offer free boxes. Use your own packaging - any sturdy corrugated box works.
FedEx Office supplies: Buy boxes at FedEx Office locations, though retail prices are higher than wholesale suppliers.
Size requirements: FedEx Ground accepts packages up to 150 lbs, 108" length, and 165" combined length + girth. Oversized surcharges apply to large packages.

One Rate for Heavy Express
FedEx One Rate saves money on packages over 10 lbs needing Express speeds.
Compare One Rate vs Standard
Always compare One Rate to standard Express pricing. Light items often ship cheaper calculated.
FedEx Pak for Documents
The FedEx Pak (reusable envelope) is often cheapest for documents and thin items.
Match Box to Contents
Using oversized boxes for small items wastes money on calculated rates due to DIM weight.
One Rate Has Weight Limit
Maximum 50 lbs for FedEx One Rate. Heavier packages use standard calculated rates.
