Cast Iron Cookware Chart of Size and Capacity

Vintage Cast Iron Cookware was at one time cast in sizes to fit the tops of wood cook stoves of that era.  Many skillets cast with heat rings.  Often times a skillet for the stove was provided with the purchase by the stove manufacturer.  The round covers (aka plates, disks, stove lids, lid plates, etc) could be lifted out of the cook stove surface (using a lid plate lifter),  The plate could be removed when more direct heat was required.  The iron skillet could be placed directly over that hole, and directly above the heat.   These removable stove top lid plates came in sizes that used references such as # 8, #9, etc.  Hence corresponding sized cookware carried a similar cast marking.
More modern and unmarked iron may not carry the No. reference to help you determine your capacities.  Below the set of charts provided you will find more conversion information that may prove helpful.

Frequently Used Conversions

8 ounces = 1 cup

2 cups = 1 pint

4 cups = 1 quart

16 cups = 1 gallon

¼ cup = 4 tablespoons

Dutch Oven Capacities

8 inch by 3 inches deep – 2 quart

10 inch by 3.5 inches deep – 4 quart

12 inch by 3.75 inches deep – 6 quart

(shallow ovens were usually used for biscuits and are often called bread ovens)

12 inch by 5 inches deep – 8 quart (known as a 12 inch deep or meat oven)

14 inch by 3.75 inches deep – 8 quart

14 inch by 5 inches deep – 10 quart

16 inch by 4.25 inches deep – 12 quart

Two 12 inch shallow camp ovens, hold approximately the same amount as one 16” oven. Most recipes that call for a 9”x13” pan will work in a 12” round pan or camp oven.

2” Deep Cake (Liner) Pans

10” round pan holds 11 cups, bottom surface = 79 square inches

12” round pan holds 18 cups, bottom surface = 113 square inches

14” round pan holds 24 cups, bottom surface = 154 square inches

16” round pan holds 32 cups

Rectangular Cake Pan Sizes

13”x9”x2” holds 14 cups, bottom = 117 sq inches

By comparing the above figures you can determine that one 14 inch pan holds almost the same as two 10 inch pans. If you have a recipe that calls for a 9 x 13 inch pan, you will see that it will fit into a 12 inch round pan or camp oven.
