6kg or 13kg gas cylinder: which size should you buy?
By Kula Kula Delivery Team · Published 1 November 2026 · Updated 1 November 2026
Choose the 6kg cylinder if you have a small household, a single burner or little storage space. Choose the 13kg (or 12kg) cylinder if you cook every day for several people and want fewer refills. Whatever you choose, compare the price per kg, not the headline price.

How to choose a size
Think about how you cook
- One or two people, simple meals: a smaller cylinder is easier to handle and to store, and the money you spend at one time is lower.
- A family cooking most meals on gas: a larger cylinder means fewer deliveries and, depending on brand, may cost less per kg (check the table).
- Students or a small rented room: a small cylinder with a compact burner takes less space. See our accessories on the prices page.
Measure instead of guessing
The best way to pick a size is to use your own numbers. Note the date you start a new cylinder and the date it runs out. If a 6kg cylinder runs out in a couple of weeks, you may be refilling too often and a 13kg cylinder could suit you better. If a 13kg cylinder lasts for months, a smaller one may be enough. How long gas lasts depends on how many burners you use, how long you cook and what you cook, so there is no honest single figure for every home.
Check space, weight and your equipment
- A full cylinder is heavier than the gas in it because of the steel. Make sure whoever moves it can lift it safely.
- Keep the cylinder upright in a ventilated place (see the safety guide).
- Burners, hoses and regulators are matched to a setup. Each kit lists what it includes on the prices page. If you change size, buy the right kit rather than mixing parts. See refill or new kit.
Frequently asked questions
Is a bigger gas cylinder always cheaper per kg?
Not always. Price per kg depends on the brand as well as the size. That is why the table above is sorted by price per kg from our live prices, so you can see what is true today.
How do I know what size my cylinder is?
The size is usually printed or stamped on the cylinder or its label, for example 6kg or 13kg. If you cannot find it, call us on +256 774 578518 before you order a refill.
Can I use a 13kg cylinder with a small single burner?
Burners and hoses are made for particular setups, so do not mix parts at random. If you are changing size, buy the kit for that size and check what it includes on the prices page, or call +256 774 578518 and ask.
