Baking potatoes requires a temperature range between 300 and 400F, depending upon the type of oven you use. Medium size potatoes will have to be baked for 45 minutes at 400F or for 60 minutes at 350F or 90 minutes at 325F in a regular oven. If you use convection ovens, you will have to bake the potatoes for 45 minutes at 375F or 60 minutes at 325F or 90 minutes at 300F. Convection ovens cook faster than regular ovens so the rule of thumb is to set the temperature in convection ovens at least 25F lower than you would set in a regular oven.
