It is crucial that the empty tins that need to be sealed are of a size that the can sealer can accommodate. Otherwise not much will be accomplished by way of dry pack canning. Unfortunately, there are a number of different can sizes with which one needs to contend, and descriptions and names can vary from one source to another. Hopefully, if you share some of the confusion that often results, the chart which follows might be of some assistance. It lists some of the cans commonly available to those doing dry pack canning at home.

Please Take Note!
Don't be fooled. The can industry numbering system is not in metric, though it may look it. The explanation: "The American can industry describes the dimensions of cylindrical cans by two three-digit numbers. The first number is the can's diameter and the second its height. In each number, the first digit is the number of whole inches, and the second two digits are the number of sixteenths of an inch. So, for example, a 303 by 407 can would be 3 03/16 inches in diameter and 4 07/16 inches high."
Please note, too, that these sizes are representative of standard can sizes as found in North America. They may not match can sizes considered "standard" in other parts of the world.
