When you purchase an oven, you must understand that the cubic feet of the oven represent the total interior volumes of the oven. However, the total interior volume of the oven dont always represent the usable interior cooking space within the oven. Many people will look at the cubic feet of the oven and assume the oven is large enough for their cooking need.
However, you must evaluate the size of the oven based off the actual dimensions of the ovens interior. You must consider the width, height, and depth of the oven to determine if the pan and dishes that you intend to cook within the oven will fit within the oven. To determine the capacity of the oven, you must use a tape measure to measure the interior of the oven.
How to Measure the Inside of Your Oven
You can measure the width of the oven from one side wall to an other side wall of the oven. You can measure the height of the oven from the bottom of the oven to the top of the oven. Additionally, you can measure the depth of the oven from the back of the oven to the front of the oven.
Measuring these dimensions will tell you the true capacity of the oven. The cubic feet of the oven that is list from the manufacturer may be the gross volume of the oven. The gross volume includes the thickness of the oven walls and the space within the corners of the oven that cannot be used to cook food.
If you measure the interior of the oven, you will find that the capacity of the oven may be less than you would of expected based on the listed cubic feet. Another important factor to consider when purchasing an oven is the capacity for airflow within the oven. Airflow is essential in cooking even dishes such as roasted vegetable.
To allow for proper airflow, space must be left between the cooking pans and the oven walls. If not left, even cooking of the food wont occur. Additionally, the oven should never be filled to 100 percent of it’s capacity.
If the oven is too full, the heat will not be able to circulate to all of the food within the oven. When cooking in the oven, it is best to fill the oven to 80 percent of its capacity. By leaving 20 percent of the oven space empty, room will be provided for the food to rise during the cooking process, and heat will be able to even distribute to all of the food being cooked.
You must also consider the dimension of the cookware you would like to use in your oven. For instance, a standard half-sheet pan is 18 inches by 13 inches, and the width of the oven must be able to accommodate a pan of this size. If you will be cooking tall item like loaf pans, the height of the oven racks must provide enough space to accommodate these items.
If you will be cooking on multiple oven racks at once, you must make sure that the racks will not become too crowded with the food that you are cooking; too much crowding will result in the food steam rather than baking. The amount of space that is provided by different types of ovens can vary. A standard range typically provides between 4.5 and 5 cubic feet of space, which is likely enough space for a family of standard size.
Compact ranges provides between 2 and 3 cubic feet of space and are typically found in small kitchens or apartments. In addition to the standard range, manufacturers also produce appliances that include two separate oven. These appliances allow cooks to prepare two different meal at once, and each at a different temperature.
However, the divider that separates the two ovens can reduce the amount of cooking space that is provided to each oven. Finally, convection ovens use a fan to circulate the hot air that cooks the food placed within the oven. Because of the convection fan, there is less space within the oven for the cooking item.
A common mistake when determining the size of the oven needed for a kitchen is to consider the gross volume of the oven and to ignore the need for space for air to circulate within the oven. The gross volume of the oven is the total amount of space within the oven, including the walls. The net volume of the oven is the amount of space that is available for the cooking pans.
If you do not allow for space for air to circulate, the food will cook unevenerly. If you attempt to cook in an oven that is too crowded with the food to cook, the cooking times will be longer then they should. By taking the dimensions of the oven, the space for air to circulate, and the amount of cookware into account, you can purchase the best type of oven for your kitchen and cooking needs.
