Choosing the right helium tank is one of the most important steps when planning a party.
A tank that is too small may run out of helium before you’ve finished decorating. A tank that is too large may cost more than you need.
Many people compare 7L, 13L, and 22L helium tanks but are unsure which size is the best fit.
The answer depends on:
In this guide, we’ll compare each tank size, explain the advantages of each option, and help you decide which helium tank is right for your next celebration.
| Tank Size | Balloon Fill* | Best For |
|---|---|---|
| 7L | 20–30 balloons | Small family celebrations |
| 13L ⭐ | 30–50 balloons | Most birthdays & home parties |
| 22L | 50–80 balloons | Weddings & large events |
*Approximate fill using standard 9–11 inch latex balloons.
A 7L helium tank is designed for small celebrations.
It is suitable if you only need a limited number of balloons.
Typical uses include:
Advantages:
However, it may not provide enough helium for larger party setups.
If you’re planning balloon arches or decorating several rooms, you’ll probably need a larger tank.
For most customers, the 13L helium tank offers the best balance between capacity, convenience, and value.
It is large enough for most home parties but still easy to transport and store.
A 13L tank is ideal for:
It can normally fill around 30–50 standard latex balloons, depending on the balloon size.
This gives you enough helium for balloon bouquets, ceiling balloons, table decorations, and small balloon displays.
If you’re planning a very large event or several balloon arches, you may need a larger tank.
A 22L helium tank is designed for customers who need a larger amount of helium.
It is the best choice for:
With enough helium for around 50–80 standard balloons, it provides more flexibility when decorating larger spaces.
Many customers choose a 22L tank simply because they don’t want to worry about running out of helium.
A larger tank costs more and may not be necessary for a small family celebration.
If you only need a few balloon bouquets, a 13L tank is often a better value.
This is one of the most common questions we receive.
For most customers, the answer is simple:
👉 13L offers the best overall value.
It provides enough helium for most birthdays and home parties without paying for capacity you may never use.
However, if you’re decorating a larger venue or creating balloon arches, the extra capacity of a 22L tank is often worth it.
Instead of asking,
“Which tank is the biggest?”
it’s better to ask,
“Which tank matches my party?”
Choosing the right size will usually save money and reduce wasted helium.
For most home parties, a 13L helium tank is our recommended choice because it offers the best balance between balloon capacity, convenience, and value. If you’re planning a larger celebration or professional balloon display, a 22L tank will provide the extra helium you need.
The number of balloons a helium tank can fill depends on several factors.
These include:
The table below is based on standard 9–11 inch latex balloons.
| Tank Size | Approximate Balloon Fill |
|---|---|
| 7L | 20–30 balloons |
| 13L | 30–50 balloons |
| 22L | 50–80 balloons |
If you’re using larger balloons or foil balloons, the total number will be lower.
For example:
If you’re unsure, it’s always a good idea to choose the next tank size up.
Different celebrations need different amounts of helium.
Choosing the right tank depends on the type of event and the decorations you want to create.
Birthday parties are the most common reason people buy a helium tank.
Most home birthdays include:
For most birthday parties, a 13L helium tank is the ideal choice.
It provides enough helium for a colourful party without paying for more capacity than you need.
Baby showers usually include a combination of latex balloons and foil balloons.
Popular decorations include:
A 13L tank is suitable for most home baby showers.
If you’re decorating a larger venue with multiple balloon displays, consider choosing a 22L tank instead.
Wedding decorations are usually much larger than birthday parties.
Many couples decorate:
Because of the larger number of balloons, a 22L helium tank is normally the better option.
It gives you more flexibility and reduces the chance of running out of helium before the decorations are finished.
Graduation parties often include:
If you’re decorating at home, a 13L tank is usually enough.
For larger venues or outdoor celebrations, a 22L tank is often the better choice.
Choosing the wrong helium tank is more common than many people think.
Here are a few mistakes to avoid.
A smaller tank may cost less, but it can quickly become more expensive if you run out of helium and need another one.
Instead of looking only at price, think about how many balloons you actually need.
Many people count the number of balloons but forget that larger balloons use much more helium.
Foil balloons, number balloons, and oversized balloons all reduce the total balloon fill.
If your decorations include these larger balloons, choosing a bigger tank is usually the better option.
Parties don’t always go exactly as planned.
You may decide to:
Having a little extra helium makes decorating much less stressful.
For most home celebrations, the 13L helium tank is the most popular option.
It offers a good balance between:
Whether you’re decorating for a birthday, baby shower, anniversary, or seasonal party, a 13L tank is usually enough for a complete setup.
If you’re decorating a larger venue or creating balloon arches, upgrading to a 22L tank provides extra flexibility and helps ensure you don’t run out of helium.
Choosing between a 7L, 13L, and 22L helium tank mainly depends on your party size and balloon plan.
A 7L tank may be enough for a very small setup, but for most UK customers, the 13L helium tank is the better choice. It has enough helium for most birthdays, baby showers, anniversaries, and home parties.
If you are decorating a larger venue, planning a wedding, or creating balloon arches, the 22L helium tank is usually the safer option. It gives you more capacity and helps you avoid running out of helium during setup.
If you are unsure, choose the larger size. A little extra helium is much better than running out halfway through decorating.
