Key Takeaways
- Amazon incorrect dimensions can place products into the wrong FBA size tier, leading to higher fulfillment costs and ongoing profit loss.
- Submitting an Amazon remeasurement request allows sellers to correct inaccurate product dimensions and stop unnecessary fee overcharges.
- To qualify for an Amazon FBA reimbursement, compare Amazon’s recorded measurements against your actual product dimensions and identify fee discrepancies.
- The highest reimbursement opportunities typically come from high-volume ASINs where incorrect measurements caused movement into a larger fee tier.
- Regular FBA fee audits and monitoring systems help sellers identify Amazon FBA incorrect dimensions before overcharges accumulate over time.
If you’ve been selling on Amazon FBA for any length of time, there’s a good chance Amazon has been quietly overcharging you, and you don’t even know it yet.
Amazon incorrect dimensions are one of the most underreported profit leaks in FBA. When Amazon measures your product incorrectly in their fulfillment centers, they place it in a higher size tier, which means you pay more in FBA fees every single time that product ships. Over weeks and months, those overcharges add up to hundreds, sometimes thousands, of dollars.
The good news? You can fix it. You can submit an Amazon remeasurement request, get your product re-measured, and recover the money you’ve been overcharged through an Amazon FBA reimbursement.
This guide walks you through the entire process, step by step, so you can stop the bleed and get back what’s yours.
How Amazon Measures FBA Products (And Where It Goes Wrong)
Before you can fix the problem, you need to understand how it happens in the first place.
Amazon’s Measurement Process
When your inventory arrives at a fulfillment center, Amazon’s warehouse staff physically measures your products and logs the dimensions and weight into their system. These measurements determine your product’s size tier, which directly controls how much you’re charged in FBA fees per unit sold.
Here’s the problem: this is a manual process done at scale in a fast-moving warehouse environment. Mistakes happen. Products get measured without packaging, with packaging, or with incorrect packaging. Items get confused with similar ASINs. And once incorrect data enters Amazon’s system, it sticks, unless you actively challenge it.
Common Reasons Amazon Records Incorrect Dimensions
There are several common scenarios where Amazon FBA incorrect dimensions creep into your account:
- Products measured without their packaging. Amazon may scan your product and measure only the item itself, not the retail box it ships in, or vice versa.
- Bundled products measured incorrectly. If you sell multi-unit bundles, Amazon sometimes measures only one unit rather than the bundle as a whole.
- Similar ASINs confused in the system. In large fulfillment centers with thousands of SKUs, it’s not uncommon for your product’s dimensions to get swapped with a similar item.
- Incorrect weight entry. A decimal point error can shift your product into an entirely different weight bracket and fee tier.
- Measurement after product changes. If you updated your packaging and Amazon re-measured incorrectly, your new fee tier may be based on bad data.
How Wrong Dimensions Increase Your FBA Fees
Amazon uses a tiered fee structure. The jump from one size tier to the next can mean a significant fee increase per unit. For example, moving from the “Small Standard” tier to the “Large Standard” tier can add $1–$3 or more per shipment in FBA fees. If you’re selling 500 units a month, that’s potentially $1,500 in monthly overcharges, or $18,000 a year, for a single ASIN.
This is why catching and correcting Amazon incorrect dimensions is one of the highest-ROI tasks you can do as an FBA seller.
How to Identify If Your Product Has Incorrect Dimensions
You can’t recover what you haven’t identified. Here’s how to check whether your products are being measured incorrectly.
Step 1: Pull Your FBA Fee Report from Seller Central
Log into Seller Central and navigate to:
Reports → Fulfillment → Fee Preview
Download the report and open it. This report lists every active FBA product along with the dimensions and weight Amazon has on file, the current size tier classification, and the fees being charged per unit.
You can also access dimension data directly by going to:
Inventory → Manage FBA Inventory → Select your product → View Product Details
Look at the “Item Dimensions” section. This is what Amazon has recorded in their system.
Step 2: Compare Amazon’s Recorded Dimensions to Your Actual Product Specs
Now measure your product yourself, accurately, with a tape measure or digital calipers. Measure the length, width, and height of the product in its shipping-ready condition (i.e., with retail packaging if applicable). Also weigh it on an accurate scale.
Write down your measurements, then compare them side-by-side with what Amazon has on file.
Things to look for:
- Any dimension that is 0.5 inches or more off
- A weight difference of 0.5 lbs or more
- A size tier that doesn’t match where your product should logically fall
Step 3: Calculate the Fee Discrepancy
Once you’ve confirmed the dimensions are wrong, calculate what you’ve been overpaying.
Use this simple formula:
Monthly Overcharge = (Incorrect Fee per Unit − Correct Fee per Unit) × Monthly Units Sold
You can find the correct FBA fee amounts for each size tier in Amazon’s FBA fee schedule.
Multiply your monthly overcharge by the number of months the incorrect dimensions have been in the system. That’s your total Amazon FBA fee refund target.
Important: Amazon typically reviews reimbursements for the past 18 months, so check your records accordingly.
Step 4: Identify Which ASINs Qualify for a Remeasurement Request
Not every dimension discrepancy will result in a lower fee tier. Before you invest time submitting a case, verify that correcting the dimensions would actually move your product into a lower tier.
Prioritize ASINs where:
- The correction would drop you at least one full size tier
- You have a high monthly sales volume (higher impact per fee dollar recovered)
- The incorrect data has been in place for many months
These are your highest-value remeasurement cases.
How to Submit an Amazon Remeasurement Request: Step-by-Step
This is the core of the process. Follow each step carefully, how you submit and phrase your case significantly affects the outcome.
Step 1: Gather Your Measurement Proof
Before you open a case, you need solid documentation. Amazon will not simply take your word for it. Prepare the following:
- Your physical measurements: Length, width, and height in inches, and weight in pounds, to two decimal places
- Photos of your product: Show all six sides with a ruler or measuring tape clearly visible
- Product packaging photos: If the packaging is being measured rather than the product itself, document the box dimensions as well
- Your ASIN and FNSKU
- A screenshot of what Amazon currently has on file (from the Fee Preview report)
The stronger your documentation, the faster and more favorably your case is resolved.
Step 2: Navigate to the Correct Contact Path in Seller Central
Go to:
Help → Get Support → Selling on Amazon → FBA Issue → FBA Product Dimensions and Weight
Many sellers make the mistake of opening a generic case and hoping for the best. Don’t do that. Use the specific FBA dimensions path — this routes your case to the right team.
If you cannot find this exact path, use:
Help → Get Support → Other Issues → Describe your issue
And clearly state in your opening line: “I am requesting a remeasurement of an FBA product due to incorrect dimensions on file.”
Step 3: Open a Case with the Correct Information
Fill out the case form with the following details:
- ASIN
- FNSKU
- Current dimensions on file (exactly as Amazon shows them)
- Your measured dimensions (with documentation)
- The fee tier discrepancy and the estimated monthly overcharge
Be factual and specific. Amazon’s support team handles thousands of cases — the clearer you are, the faster they move.
Step 4: Write an Effective Case Message
This is where many sellers lose the case before it even starts. Here’s a template you can use:
Hello,
I am writing to request a product remeasurement for ASIN [ASIN] / FNSKU [FNSKU].
Amazon’s current recorded dimensions are: [L x W x H, Weight]. However, I have physically measured this product and the correct dimensions are: [L x W x H, Weight].
This discrepancy has placed my product in the [Incorrect Tier] size tier when it should fall under [Correct Tier]. I have attached photos of the product with measurements clearly visible.
I respectfully request that Amazon re-measure this product at the fulfillment center and update the dimensions accordingly. I also request a review of FBA fees charged since [Date the incorrect dimensions were applied] for potential reimbursement.
Thank you for your attention to this matter.
Keep the tone professional and factual. Avoid emotional language or accusations. Attach your photos directly to the case.
Step 5: Submit and Track Your Case
After submitting, save your case ID. You will need this to follow up if you don’t hear back within 5–7 business days.
Track your case under:
Help → Case Log
If the case closes without resolution or with a generic response, reopen it. Do not open a new case for the same issue, that creates conflicting records.
How to Get Your Amazon FBA Fee Refund After a Successful Remeasurement
Getting the dimensions corrected is step one. Getting your money back is step two, and it’s a separate process.
What Happens After Amazon Re-Measures Your Product
Once Amazon completes the remeasurement, they will update the dimensions in their system. You will typically see a confirmation in your case log and an updated product page in Seller Central within 7–14 business days.
At this point, your ongoing fees will be corrected automatically. But Amazon does not automatically reimburse you for the fees you were overcharged in the past. You have to ask.
How to Request Amazon FBA Fee Reimbursement for the Overcharged Period
Once your remeasurement is confirmed, reopen your original case — or open a new case referencing it, and submit a reimbursement request.
Your message should include:
- The original case ID for the remeasurement
- The date range during which the incorrect dimensions were in effect
- Your calculated fee discrepancy per unit
- Total units sold during that period
- Total estimated overcharge (your calculation)
Ask Amazon to audit the overcharged period and issue an Amazon FBA fee refund for the difference.
Calculating How Much You’re Owed
Here is the formula again:
Total Reimbursement = (Fee Overcharge per Unit) × (Units Sold During Incorrect Period)
Pull your unit sales history from:
Reports → Business Reports → Detail Page Sales and Traffic by Child Item
Filter by the ASIN and the date range in question.
Timeline: How Long Amazon FBA Fee Refunds Take
In most cases, once a remeasurement is confirmed:
- Dimension correction: 7–14 business days
- Reimbursement review: 14–30 business days
- Credit applied to your account: 3–7 business days after approval
Be patient, but be persistent. Follow up every 7–10 days if you don’t receive an update.
What to Do If Amazon Denies Your Remeasurement Request
Denials happen. They are not final. Here’s how to push back effectively.
How to Escalate the Case
If your initial case is closed without action, reopen it and escalate. In your follow-up message, include the phrase: “I would like to escalate this case for further review.”
If escalation through the standard case log doesn’t work, you can also contact Seller Support via phone (where available in your region) and reference the case ID. Speaking directly with an agent often moves things faster than email-only communication.
Use a Third-Party Measurement Certificate as Proof
If Amazon insists their on-file dimensions are correct, consider having your product measured by a third-party measurement service or a certified logistics company. Some sellers use services like a UPS Store or a freight company to issue an official measurement certificate.
Submit this certificate as documentation in your case. An independent measurement from a credible third party significantly strengthens your claim.
Resubmitting with Stronger Evidence
If your case was denied due to insufficient documentation, do not give up. Rebuild your evidence:
- Photograph the product with a professional ruler on all six sides
- Include photos of the packaging with a tape measure
- Attach any manufacturer spec sheets that confirm the dimensions
- If possible, include a video walkthrough of the measurement process
Submit a new case with this enhanced documentation. Many sellers win on their second or third submission simply by providing clearer proof.
How to Automate FBA Reimbursement Monitoring
Manually auditing every ASIN every month is not scalable. Here’s how to build a smarter system.
Tools to Audit Amazon FBA Incorrect Dimensions Automatically
Several third-party tools specialize in identifying FBA fee discrepancies and incorrect dimension charges:
- GETIDA: One of the most well-known Amazon FBA reimbursement services. Works on a success-fee model (no upfront cost).
- Helium 10 Refund Genie: Identifies reimbursement opportunities across multiple categories including dimensions, lost inventory, and damaged goods.
- Sellerboard: Provides ongoing profitability tracking and flags fee anomalies.
- Refund Sniper: Focuses specifically on FBA fee discrepancies and overcharges.
Each tool has slightly different coverage and fee structures. Evaluate them based on your catalog size and monthly revenue.
Setting Up Recurring Fee Audits
Whether you use a tool or do it manually, build a recurring audit into your operations:
- Monthly: Pull the FBA Fee Preview report and check your top 20 ASINs by sales volume
- Quarterly: Do a full catalog audit, every ASIN, every dimension on file
- After any packaging change: Immediately re-audit that ASIN and pre-emptively request a remeasurement if needed
Make this a standing item on your operations calendar. It takes less than an hour once you build the habit.
Manual vs. Tool-Based Auditing
If you have fewer than 50 ASINs, manual auditing is perfectly manageable. If you’re managing hundreds of SKUs, a third-party Amazon FBA reimbursement service will pay for itself quickly. The key is that you’re doing something, because Amazon will not flag overcharges on your behalf.
3 Pro Tips to Prevent Incorrect Dimension Charges in the Future
The best strategy is to catch problems before they cost you money. Here’s how experienced FBA sellers stay ahead of this issue.
1. Document Your Product Specs Before Sending to FBA
For every product you send to Amazon, maintain a master spec sheet that includes:
- Verified dimensions (L x W x H) with and without packaging
- Exact weight to two decimal places
- Photos of the product with a ruler on all six sides
- Correct size tier classification based on Amazon’s current fee schedule
Store this documentation somewhere accessible. If you ever need to challenge Amazon’s measurements, you’ll have everything ready immediately.
2. Request a Remeasurement Proactively After a Product Update
Any time you change your packaging, even slightly, treat it as a trigger event. Submit a proactive remeasurement request before the old dimensions cause overcharges.
This is a simple case to open:
“I have updated the packaging for ASIN [ASIN]. The new dimensions are [L x W x H, Weight]. I would like to request a re-measurement to ensure our fees reflect the correct specifications.”
Proactive remeasurement requests are faster and easier to resolve than reactive disputes.
3. Audit Your FBA Fee Reports Regularly
Build a habit of running the FBA Fee Preview report monthly. Look for any ASIN where the size tier has changed unexpectedly, or where the fees per unit seem inconsistent with your records.
A sudden increase in per-unit fees on a product you haven’t changed is almost always a signal worth investigating.
Conclusion
Amazon incorrect dimensions may seem like a minor catalog issue, but they can quietly drain profits month after month through inflated FBA fees. The key is building a proactive process: audit your fee reports regularly, verify your product measurements, and act quickly when discrepancies appear. Sellers who monitor their catalog closely and submit well-documented Amazon remeasurement requests often recover substantial amounts that would otherwise go unnoticed.
If you’re managing a large catalog, struggling with reimbursement claims, or simply don’t have time to audit FBA fees manually, AMZDUDES, a full-service Amazon agency, can help identify hidden reimbursement opportunities, manage the process end-to-end, and recover lost profits efficiently.
