Package dimensions bring the cost to Amazon sellers and can be one of the reasons for losing money while doing FBA.  This is why package dimensions should be checked once a quarter to verify if the dimensions you measured were the same as Amazon’s measurements or not.

Short Answer

First, confirm the package dimensions that Amazon has measured and charge FBA fees accordingly.

Either download the fulfillment report and check the dimensions or check on the FBA calculator by using one of the product ASINs that you need to check.

Verify if the package dimensions are recorded accurately or not. If not then open a case on Amazon and request remeasurement.

How to Save Money on FBA with Correct Package Dimensions?

On various occasions where the dimensions scanned by Amazon are not similar to what the seller measured previously then due to this, there can be differences in FBA fees.

The seller needs to check the dimensions measured by Amazon by the 2 methods mentioned above and check how much FBA fees are charged by Amazon.

The seller needs to ensure that products with similar package dimensions are being charged the same FBA fees, let it be their own product’s variations or their competitor’s product.

If the seller’s product FBA fees are higher than its variations or competitor’s product even if the package dimensions are similar then the seller needs to open a case with Amazon customer support.

How to Request Amazon to Remeasure Package Dimensions?

When the seller identifies ASINs which need remeasurement to correct the FBA fees then they have to open a case with Amazon customer support. Follow the instructions below to open a case,

Amazon provides all sellers with 20 measurement requests per month.

Amazon will pay the seller the difference in the FBA fees they charged me previously If Amazon finds out that the new dimensions are lower than the previous dimensions.

If the dimensions remain the same then there is no change in the fee.

If the dimensions are increased with new measurements then FBA fees will be higher from the next shipments.


You have to be careful when using Cubiscan and only use this option when you are sure that Amazon is charging higher fees for your products. Cubiscan can save a lot of your money.

On one of my ASINs, I noticed a difference of $1.88 higher FBA fees than other variations. I can lose $1880 If I sell 1000 units whereas when dimensions are corrected I can save $1880 along with previous overcharges.
