Explanation of Dimensional Food Can Standards

Metal can sizes used in industry in the U.S.A. are derived from nominal outside dimensions. Measurements are made of the empty round can before seaming on the packers' end.

While such dimensions may be expressed in inches, the custom is to use a conventionalized method in which three-digit numbers are used to express each dimension. The first digit indicates the number of whole inches in a dimension, and the second and third digits indicate the fractional inches as sixteenths of an inch. Thus:

303 x 406 means 3-3/16 x 4-6/16 inches
307 x 512 means 3-7/16 x 5-12/16 inches
603 x 700 means 6-3/16 x 7 inches

The first three-digit number describing a round can indicates the diameter measured across the outside of the chime on the seamed end. The second three-digit number indicates the overall height of the can with one end on.

In stating the dimensions of oval, obround, or obrotund cans, outside dimensions are used, the dimensions of the opening stated first, followed by the height. Thus, there will be three sets of figures: the first two being the long and short axis of the opening. Their interpretation in inches and sixteenths of an inch is the same as with round cans. An oval can might have the size given as 402 x 304 x 612, which would mean that the oval opening was 4-2/16 x 3-4/16 inches and the height was 6-12/16 inches.

In the table below the "No. 2 Equivalent" indicates the number of No. 2 cans equal to each of the cans designated in Column 1.
