You just need to measure the space. Most ranges are 30 inches wide, but could be 36 inches or more, so first measure the width of the space. You also need to measure the depth, or far from the wall to the counter. While most ranges today are designed to fit in the designated space, even a half-inch too wide or too deep can make the range a huge headache to install. So make sure the stove you choose is no larger than any of the measurements. You can find out more by looking at home appliance sites or asking your local appliance dealer.
