If you're unsure about what kind of oven you have, there are a few ways to figure it out. The first step is to identify whether your oven is a gas or electric model. If it's a gas oven, it will likely have a pilot light somewhere near the front of the stove. Electric ovens, on the other hand, will usually have a control panel with various dials and buttons.
Once you've determined the type of oven you have, the next step is to find out its size. Most home kitchens have either a standard or compact-sized oven. Standard-sized ovens typically measure between 20 and 30 inches wide, while compact models are usually 18 inches wide or less. To get an accurate measurement of your oven's width, open the door and use a tape measure to record the distance from one side of the interior to the other.
Finally, take note of any special features your oven might have that could affect its cooking performance. For example, some electric models come with a convection setting that circulates hot air around food for faster and more even cooking results. If your oven has this feature, be sure to use it according to manufacturers' instructions in order to avoid overcooking or undercooking your food.
