What Is Amazon FBA Large Bulky and Extra-Large Inventory?
Large bulky and extra-large (previously called oversize) inventory on Amazon refers to products that exceed the standard size and weight limits. Due to irregular dimensions, these products require special handling and storage.
Products that exceed standard limits set by Amazon are charged additional fees, and their shipping and fulfillment options differ from standard-sized products.
Since February 5, 2024, Amazon has made changes to oversize product size tiers and replaced them with the new large bulky and four extra-large sizes.
Amazon Large Bulky and Extra-Large Tiers
Amazon has five different size tiers for large bulky and extra-large products, ranging from “large bulky” to “extra-large 150+ lb”. Each tier has its own size and weight limits.
Breakdown of Amazon's large bulky and extra-large tiers
Large bulky
Large bulky are products larger than large standard-sized items, with a shipping weight of up to 50 pounds, the longest side of up to 59 inches, the median side of up to 33 inches, the shortest side of up to 33 inches, and a length of up to 130 inches.
Extra-large
Extra-large are products with unit weight or dimensional weight larger than 50 lbs, the longest side of over 59 inches, the median side of over 33 inches, the shortest side of over 33 inches, and a length of up to 130 inches. The extra-large tier has four sub-tiers.
- Extra-large 0 to 50 lb — products with a shipping weight of up to 50 pounds;
- Extra-large 50+ to 70 lb — products with a shipping weight of 50+ to 70 pounds;
- Extra-large 70+ to 150 lb — products with a shipping weight of 70+ to 150 pounds;
- Extra-large 150+ lb — products with a shipping weight of over 150 pounds.
How to Determine the Product Large Bulky and Extra-Large Tier?
To determine your product’s large bulky and extra-large tier, you must calculate its volume and shipping weight. Amazon calculates the volume of the product by multiplying its length, width, and height.
To identify the size tier, you must first determine the volume and dimensions of your product. Then, measure the item’s shipping weight and dimensional weight (a calculation of the volumetric weight of a package using the package’s length, width, and height). Shipping weight is the greater of unit weight or dimensional weight. Compare your values and the numbers in the table below to get the product size tier.
If your product’s volume exceeds the maximum for a particular size tier, it will be classified as the next highest tier.
Example of product size tier calculation
Product
Large yoga mat (assume dimensions: 72 inches long, 24 inches wide, and 0.5 inches thick)
Weight: 5 pounds (assumed weight)
Amazon large bulky criteria
- Max weight: 50 lbs (our yoga mat meets this with 5 lbs)
- Max length: 130 inches (our yoga mat is 72 inches, well within the limit)
- Max median side: 33 inches (median side is the average of width and height. In this case, (24 inches + 0.5 inches) / 2 = 12.25 inches, which is well under 33 inches)
Dimensional weight calculation
Amazon uses a formula to calculate dimensional weight (Dim weight):
Dim weight (lbs) = (length x width x height) / divisor (139, cubic inches per pound)
For our yoga mat:
Dim weight = (72 inches x 24 inches x 0.5 inches) / 139 cubic inches/lb = 6.55 lbs (approximately)
Determining size tier
- Actual weight: The yoga mat weighs 5 pounds.
- Dimensional weight: We calculated the Dim weight to be approximately 6.55 lbs.
Amazon considers the greater of the two:
- In this case, the dimensional weight (6.55 lbs) is greater than the actual weight (5 lbs).
Conclusion
Since the dimensional weight (6.55 lbs) is greater than 5 lbs and exceeds some of the dimensional limits for large bulky, the yoga mat might not qualify for large bulky.
Note. Dimensional weight equals the unit volume (length x width x height) divided by 139. The dimensional weight for large bulky and extra-large items assumes a minimum width and height of 2 inches.
For FBA, Amazon uses dimensional weight when it’s greater than the unit weight for small large bulky, and extra-large products (excluding 150+ pounds), to calculate fees. Fees for small standard-size products and extra-large 150+ pound units are calculated using only unit weight.
For Multi-Channel Fulfillment (MCF), the dimensional weight is calculated for all large bulky and extra-large items, regardless of whether the item is apparel.

Amazon will then measure and weigh your product to determine its size tier and charge you the appropriate fees. Amazon may also require additional handling and packaging for large bulky and extra-large items, further impacting the fulfillment cost.

Storage fees
Storage fees for storing large bulky and extra-large inventory in Amazon warehouses are also higher than for standard goods. Storage fees are calculated based on the daily average volume of the space inventory occupies. The rate is based on product type, size tier, and time of year.
It’s important to note that these fees are in addition to the standard FBA fees, referral fees, and other charges that may apply to your product. As an Amazon seller, it’s essential to consider these fees when pricing your product and calculating your profit margins.
