How much does a full keg of beer weigh?

A full 50-litre steel beer keg weighs roughly 60–65kg, depending on the container and the beer inside. Smaller kegs weigh less, but the material matters too: a 20-litre steel keg can be substantially heavier than a 20-litre lightweight plastic keg.

Whether you’re ordering for a pub, a home bar or an event, knowing the full weight helps you plan delivery, storage and how you’ll move the keg into position.

Beer keg weights at a glance

A keg’s advertised size tells you how much beer it holds—not how much the filled container weighs. These examples use published empty-container weights and assume approximately 1kg per litre of beer.

Container weights come from THIELMANN’s EURO keg specifications and KeyKeg’s technical specifications. These are illustrative estimates, not guaranteed weights for every brand. Beer density, fittings and packaging can affect the final figure.

Why does a full keg weigh more than its litre capacity?

The total consists of the beer plus the container and its fittings. The empty-container weight is often called the tare weight; the filled total is the gross weight.

For a rough estimate:

Full keg weight ≈ litres of beer × 1kg + empty keg weight

Beer is close enough to 1kg per litre for a useful initial estimate, although its exact density varies with its composition. A litre figure alone therefore isn’t sufficient for calculating a delivery load or checking an equipment weight limit.

How much does a full 50-litre keg weigh?

For a conventional steel 50-litre keg, roughly 60–65kg is a useful guide rather than a universal specification. Lighter container designs and heavier constructions can fall outside that range.

A 50-litre keg contains approximately 88 UK pints before allowing for foam, line cleaning or beer left in the system. That makes it a substantial volume of beer—and a substantial load to move.

Does a 20-litre keg weigh 20kg?

Not usually. The beer alone weighs approximately 20kg, and the container adds to that total. A lightweight 20-litre KeyKeg is around 21kg when filled, while the steel example in the table is around 29kg.

This explains why two kegs containing the same amount of beer can have noticeably different delivery weights. Also check the required coupler: containers with the same capacity are not necessarily compatible with the same dispensing equipment.

Is an 11-gallon keg the same as a 50-litre keg?

In UK beer listings, “11 gallon” commonly refers to the approximately 50-litre format: 11 imperial gallons equals about 50 litres.

Always check the stated capacity, particularly when reading overseas guides. US gallons are smaller than UK imperial gallons, so an American keg chart may describe a different size.

Moving and storing a full keg

Plan the route from the delivery point to your bar before the keg arrives. Steps, gravel, narrow doors and lifting into a fridge can all make handling more difficult.

Use a suitable keg trolley or lifting aid, and check the load rating of any platform or storage surface. A smaller keg is easier to manage, but it is not automatically safe for one person to lift. HSE guidance assesses manual handling using the load, task, environment and person; weight alone does not establish safety. HSE manual handling guidance

Choosing the right keg for your setup

Before ordering, check the beer volume, filled weight, physical dimensions and dispensing connection. If your access is restricted, a smaller keg may be more practical—but it still needs to suit your equipment and the quantity of beer you require.
