Enter the length, width and height of your package.

How to measure

Step 1: Measure the three sides

Use a tape measure to measure the length, width and height of your packed box or case.

  • Length is the longest side of your box or case

  • Width is the second-longest side

  • Height is the remaining dimension

Write down each measurement.

Be sure to measure at the longest, widest and tallest points of your packed box or case, including any bulges, bowing, crushed corners, tape seams, uneven flaps, straps, handles and wheels.

Step 2: Check for bulging

Packages often bulge once packed.

To check for bulging:

  1. Gently lay your package on its side, the same way it moves along carrier belts during transit.

  2. Look at each corner. If you see a gap between the corner of the box or case and the floor, that indicates bulging.

  3. Measure the largest gap from the floor to the corner.

To account for bulging on both sides, double the largest gap measurement and add it to your original height (shortest side) measurement.

This gives you a more accurate width measurement for your package.

Step 3: Round up

Always round up any fractional measurement to the next nearest inch.

For example:

  • 12.25 inches → enter 13 inches

  • 47.125 inches → enter 48 inches

Why accurate dimensions matter

Accurate dimensions are required for every Bikeflights shipment. Carriers use automated laser systems to scan and measure packages multiple times during transit. If scanned dimensions don’t match what you entered when booking, you’ll receive a carrier adjustment charge or credit to account for the difference.

Pre-loaded dimensions

We’ve pre-loaded the dimensions of Bikeflights Bike Boxes and many popular shipping cases. If you’re using one of these, you can select its dimensions from the dropdown when booking.

However, you should always confirm the dimensions of your specific case after you’ve packed it, including any bulges. If your measured dimensions differ from the pre-loaded dimensions, manually enter the dimensions you measured when booking.
