A 17-inches Blackstone griddle is often used for people who want to have outdoor picnics and tailgating. This is because 17-inches griddles are portable.

Propane tank size for the Blackstone 28 griddle

The 28-inch Blackstone griddle is not suitable for portable cooking outside the home. This means that you no longer need to get smaller propane tanks since you do not have to move them around.

Propane tank size for the Blackstone 36 griddle

Just like the Blackstone 28-inch griddle, its 36-inch griddle will also require a larger propane tank. Using a 5-pounds tank on a 36-inch griddle will not let you cook for long. Typically, it will only take you up to 2 to 3 hours to consume the whole tank.

Unless you want to cook only one meal, use a 20-pounds propane tank for Blackstone griddle that has a 36-inch griddle.
