Quick size guide
Propane for camping generally comes in a few common sizes. Exact dimensions and capacities vary by brand and country, so check the label on your own cylinder.
| Size | Typical use |
|---|---|
| 1 lb (about 16 oz) | Single-burner stoves, lanterns, short trips |
| 5 lb refillable | Car camping, small grills, longer weekends |
| 20 lb | Backyard-grill style cylinder, larger camp kitchens |
| Larger (30 lb and up) | RVs and fixed installations |
1 lb cylinders
The small green-style disposable cylinders are the most common camping size. They are light, easy to pack and fit many two-burner and single-burner stoves and lanterns. They are best for weekend trips, and several can be bought in multipacks. Run time depends on the appliance and heat setting, so manufacturers’ figures are the best guide, and many cooks carry a spare. Disposable cylinders create waste, and some areas have recycling rules for empty ones, so check locally. Some refill adapters exist for these cylinders, but follow the cylinder maker’s instructions, since many are designed for single use.
5 lb and other mid-size refillables
A 5 lb refillable cylinder holds roughly the same fuel as several 1 lb cylinders, so it suits car campers who want less waste and fewer refills; our car camping cooking guide shows what a two-burner setup needs. They are heavier and bulkier, and need a hose to connect to a stove. They can be refilled at many propane dealers or exchanged, depending on local services.
20 lb cylinders
A 20 lb tank is the standard barbecue-style cylinder in many places. It lasts a long time for cooking and is common at base camps and larger group setups. It is heavy when full and needs to be transported and stored upright and secured, so it is mostly useful for car camping or trailers, not backpacking.
Larger tanks (RV and home)
RVs often carry fixed or removable tanks of about 20 to 40 lb or more (see RV camping essentials for the rest of a rig’s gear). Home and commercial tanks run into the hundreds of gallons and are not used for tent camping. If you are wondering how long an RV tank will run an appliance such as a fridge, usage depends on the model, temperature and how often it runs on gas, so check the appliance specs and monitor your tank.
Choosing a size
Think about:
- Trip length and number of people: more meals mean more fuel.
- What you are powering: a lantern uses much less than a stove, and a camp shower heater uses more. Our guide on where to shower when camping explains how propane fits into hot-water setups.
- Weight and space: compact cylinders suit smaller cars.
- Connection type: check whether your stove screws on directly or needs a hose or adapter.
A good habit is to carry a little more than you expect to need, or a spare cylinder.
Refilling vs exchanging
Refilling at a dealer is often cheaper per pound and cuts waste, but you need a cylinder that is in date and in good condition. Exchange is faster but may return less fuel than a full cylinder. Many tanks need requalification after a set number of years, and dealers typically refuse out-of-date or damaged ones. Do not attempt to refill cylinders yourself unless they are designed for it and you follow the instructions exactly.
Transport and safety basics
- Carry cylinders upright and secure them so they cannot tip or roll.
- Keep them out of hot, enclosed vehicles and away from direct sun for long periods.
- Never use propane stoves, lanterns or heaters inside a tent, as carbon monoxide and fire are serious risks. More on staying safe is in camping survival skills.
- Check hoses and seals for damage and leaks before each trip, using soapy water, never a flame.
- Follow local rules, since some campgrounds, ferries and tunnels restrict propane.
