Enter the length, width and height of your package. To determine these dimensions, measure your packed box or case at its outermost longest, widest and tallest points, then round up each measurement to the next whole inch, just like the carriers do.
When your package is in transit, the carrier measures it using federally monitored equipment, including automated laser scanners and scales, and rounds up any fractional measurements to the next whole inch. If the carrier's measured dimensions differ from what you entered when booking, you'll be charged a carrier billing adjustment to account for the difference.
Measuring and rounding the same way as carriers helps you avoid carrier adjustments.
How to measure
Step 1: Measure all three dimensions
Boxes and cases naturally bulge when packed, so measure the outermost longest, widest and tallest points of your packed box or case, including all bulges, bowing, crushed corners, tape seams, uneven flaps, straps, handles and wheels.
Length is the longest side of your box or case
Width is the second-longest side
Height is the remaining dimension
Simply measuring along the flat sides or edges between corners of your box or case doesn’t account for bulges that occur after packing. To check and account for bulging:
Gently lay one side of your package on the floor (or stand it up against a flat wall).
Look at each corner of your package along the floor (or wall). If you see a gap between a corner of your package and the floor (or wall), that indicates bulging.
Measure the largest gap from each corner of your package to the floor (or wall).
Double that gap to account for likely bulging in both directions, and add it to your longest corner-to-corner or edge-to-edge measurement for that particular dimension.
Repeat steps 1-4 for the other two dimensions.
Step 2: Round up
Round up each fractional length, width and height measurement to the next whole inch just like the carriers do.
For example:
12.25 inches → enter 13 inches
47.125 inches → enter 48 inches
Always Check Pre-loaded dimensions
We’ve pre-loaded the dimensions of Bikeflights Bike Boxes and many popular shipping cases. You can select your box or case from the dropdown to get a quick estimate of shipping costs.
However, always confirm the actual dimensions of your specific box or case after packing and before booking, including any bulges. If your measurements differ from the pre-loaded dimensions, manually enter the dimensions you measured instead.
