Largest Amazon Warehouses in 2026: Verified Sizes and Limits

There is no reliable public, continuously updated ranking of every Amazon warehouse by size. “Largest” can mean building footprint, total floor area across multiple levels, storage volume, site acreage, package capacity, or workforce. The strongest current answer is to compare facilities Amazon has described with a date and measurement rather than repeat an undated top-10 list.

Two of the clearest U.S. examples are multi-level fulfillment centers in Shreveport, Louisiana, and Mt. Juliet, Tennessee. Amazon describes the Shreveport site as more than 3 million square feet and one of its largest; an Amazon fact sheet describes the Mt. Juliet site as 3.2 million square feet.

Large Amazon facilities with published measurements

Facility	Published scale	Important context
Shreveport, Louisiana	More than 3 million square feet across five floors	Amazon called it one of its largest sites when unveiling the next-generation robotics facility in 2024.
Mt. Juliet, Tennessee (MQY1)	3.2 million square feet across five floors	Amazon's facility fact sheet also cites extensive conveyance and small-item fulfillment capacity.
Fargo, North Dakota	More than 1 million square feet	Amazon described it at opening as the state's largest structure by square footage.
Ottawa, Canada (YOW1)	About 1 million square feet	A large single fulfillment center completed in roughly a year, according to Amazon's construction feature.
Brisbane, Australia project	Planned 150,000 square meters across four levels	Announced in 2026 for targeted completion in 2028; it is not yet an operating warehouse.

These figures are not perfectly comparable. Some count the total usable floor area across several levels, while older announcements may emphasize a building footprint or site acreage.

Shreveport: one of Amazon's largest operating sites

Amazon's 2024 Shreveport facility report says the building spans five floors and more than 3 million square feet. It describes the site as one of Amazon's largest and says the Sequoia inventory system can hold more than 30 million items.

The facility is notable not just for size but for its integrated robotics. Floor area alone does not measure throughput: inventory system design, item mix, automation, staffing, inbound flow, and downstream transportation all matter.

Mt. Juliet: a 3.2-million-square-foot reference point

An Amazon operations fact sheet describes MQY1 in Mt. Juliet, Tennessee, as 3.2 million square feet across five floors. That makes it a useful scale reference and potentially larger than Shreveport by the rounded published number.

It would still be too strong to declare MQY1 the permanent “world's biggest Amazon warehouse.” Amazon can open, expand, repurpose, sell, or close facilities, and public measurements may use different methods.

Fulfillment center, sort center, delivery station, and air hub

“Amazon warehouse” covers several different operations:

Fulfillment centers store inventory and pick, pack, and ship customer orders.
Sortation centers group packages by destination after fulfillment.
Delivery stations prepare packages for last-mile routes.
Air hubs transfer packages between aircraft and the ground network.
Specialty/AMXL sites handle bulky products that need different storage and delivery.

The Cincinnati/Northern Kentucky Amazon Air Hub, for example, was announced as an 800,000-square-foot building on a site spanning more than 600 acres. Its acreage is huge, but comparing an airport ramp with a multi-story fulfillment center does not answer which “warehouse” is largest.

Why online largest-warehouse lists conflict

They mix announced projects with operating facilities.
They combine footprint, total floor area, site acreage, and storage volume.
They repeat “largest in the region” as “largest in the world.”
They use proposed measurements after a plan has changed.
They do not account for closures, subleases, sales, or repurposing.

A trustworthy comparison should name the facility code or city, measurement, source date, operational status, and what the number represents.

What makes a large warehouse useful?

Size can support broad selection and consolidated operations, but a very large building is not automatically the fastest or most efficient. Amazon's network places inventory across many sites so products can be closer to customers. Smaller same-day sites and delivery stations can be more important for a particular order than the largest building.

Useful operating measures include units stored, order cycle time, packages per day, inventory placement, automation, transportation connections, safety, and distance to demand—not square footage alone.

How to verify a claimed Amazon warehouse size

Prefer an Amazon operations article, press release, government filing, or property document.
Check whether the facility is proposed, under construction, open, or closed.
Identify whether the measurement is footprint, total floor area, acreage, or volume.
Keep “one of the largest,” “largest in a state,” and “largest worldwide” separate.
Record the source date because the network changes.

Bottom line

Shreveport and Mt. Juliet are among the largest Amazon fulfillment sites with clear company-published measurements, each around or above 3 million square feet across multiple floors. But Amazon has not supplied a live global leaderboard, so a permanent “biggest” claim is not defensible. Compare dated, like-for-like facility measurements instead.
