6kg vs 12.5kg: Which Gas Cylinder Size Is Right for You?
Standing in front of the vendor, one question always comes up. Which cylinder size should I actually buy? The two most common are the 6kg and the 12.5kg. And the right gas cylinder size depends on how you cook, not just the price on the day.
Both are good choices for the right home. The trick is matching the size to your kitchen and your habits. Here is how the two compare, so you can buy with confidence.
The quick answer
If you want it in one line, here it is. A 6kg suits small households, light cooking, and anyone who values portability. A 12.5kg suits families, daily cooking, and anyone who wants better value per kilogram. Most homes that cook every day land on the 12.5kg. The rest comes down to the details below.
The case for the 6kg cylinder
The 6kg is the light, easy option. It is simple to carry, simple to store, and it fits a small kitchen with room to spare. Each refill costs less in one go, since you are buying less gas at a time. That makes it a comfortable fit for a single person, a small flat, or anyone who cooks lightly. The trade-off? It runs out sooner, so you refill more often. And buying less at a time can cost slightly more per kilogram.
The case for the 12.5kg cylinder
The 12.5kg is the standard family size, and for good reason. It holds much more gas, so you refill far less often. That bigger fill usually works out cheaper per kilogram. For a household that cooks daily, it is the natural choice. The downsides are simple to weigh up. It is heavier to move, it costs more in one go to fill, and it needs a bit more space. For most families, none of that outweighs the convenience.
It really comes down to cost per kilogram
Here is the part many people miss. The real comparison is not the price of a fill, but the price per kilogram. A bigger fill usually costs a little less for each kilogram of gas. So if you cook a lot, the 12.5kg tends to stretch your money further over a month. If you cook lightly, the 6kg may suit you better, even at a slightly higher rate. Our buying guide explains how to think in price per kilogram.
How much do you actually cook?
This is the question that settles it. Be honest about your kitchen. Do you cook full meals every day, for several people? The 12.5kg will serve you better, with fewer trips to refill. Do you cook now and then, or just for yourself? The 6kg is lighter and easier to manage. Match the size to how you genuinely cook, not to the smallest amount you can pay today.
Space, weight, and handling
Practical things matter too. A 6kg is light enough for almost anyone to carry and tuck away. A 12.5kg is noticeably heavier, which is worth thinking about if you live upstairs or have limited space. That said, weight is less of an issue when your gas is delivered. Our delivery service brings either size to your door, so you never have to haul a heavy cylinder yourself.
Can you have both?
Yes, and it is a smart move. Many homes keep a 12.5kg as the main cylinder, plus a small 6kg as a backup. When the big one runs dry mid-cooking, you switch to the spare and finish your meal. Then you refill at your own pace, instead of scrambling. It is a simple way to never be caught out by an empty cylinder.
So, which should you choose?
Keep it simple. If you cook daily for a family and want the best value, go with the 12.5kg. If you cook lightly, live alone, or want something easy to carry, the 6kg is your friend. And if you would like the best of both, a 12.5kg main with a 6kg backup covers you nicely. There is no wrong answer, only the size that fits your kitchen.
Frequently asked questions
Which lasts longer, 6kg or 12.5kg?
The 12.5kg holds roughly twice as much gas, so it lasts much longer between refills. How long depends on how much you cook.
Is a 12.5kg cheaper than a 6kg?
Not in one go, since you are buying more gas. But per kilogram, a bigger fill usually works out a little cheaper. That is where the value is.
What size is best for a small family?
For a family that cooks daily, the 12.5kg is usually the better fit. It means fewer refills and better value over the month.
Can I switch sizes later?
Of course. Many people start with a 6kg, then move up to a 12.5kg as their cooking grows. You are never locked in.
The best gas cylinder size is simply the one that matches how you cook. Think about your household, your kitchen, and how often you want to refill. Get that right, and the choice between 6kg and 12.5kg becomes easy.
