How to use the Size Tier Classifier

Input packaging dimensions and weight.
System alerts if even 0.1 inch pushes you into Oversize fulfillment fees ($9.73+ base).

Before using the result, check that every amount, percentage, unit and date matches the source information you intend to analyze.

Inputs used by this tool

The calculator displays the following fields. Your exact inputs depend on the selected tool and its available options.

Longest Side (in)
Median Side (in)
Shortest Side (in)
Packaged Weight (lbs)

Calculation method and formula

The tool's registered calculation explanation is:

Standard Size criteria: Longest side <= 18", median side <= 14", shortest side <= 8", and weight <= 20 lbs.

The result depends on the values you enter and the assumptions built into the tool. Where marketplace fees, carrier prices or tax rules apply, confirm the latest official figures before relying on the estimate.

Practical tips before you use the result

Use current figures from your Seller Central reports, supplier quotation, invoice or other primary records.
Keep the units consistent. Do not mix inches with centimetres, kilograms with pounds, or one currency with another.
Test more than one realistic scenario when comparing prices, costs or campaign settings.
Save or record the result you need before closing or refreshing the page.
Standard-size limits are strictly 18 × 14 × 8 inches and 20 lbs; shaving 0.5 inches off retail packaging can save $4.00+ per unit in FBA fulfillment fees.
Request a cubiscan remeasurement via Seller Central immediately if Amazon warehouse scanners mistakenly record inflated dimensions.

Use confirmed carton dimensions, gross weights and freight quotations. Carriers and fulfillment networks apply their own measurement and billing rules.

Worked example: Size Tier Classifier

Sample inputs:

Longest Side (in): 17.5 in
Median Side (in): 12 in
Shortest Side (in): 6.5 in
Packaged Weight (lbs): 4.2 lbs

Calculation:

Size Tier = Standard-Size Product
Dimensions = 17.5x12x6.5 in
Weight = 4.2 lbs

Result: Size Tier: Standard-Size Product, Dimensions: 17.5x12x6.5 in, Weight: 4.2 lbs

Executing the tool logic with these inputs yields Size Tier: Standard-Size Product, confirming operational profitability and compliance.
