WebElements have the properties such as .size and .location. Both are of type dict.
driver = webdriver.Firefox()
e = driver.find_element_by_xpath("//GiveXpath")
location = e.location
size = e.size
print(location)
print(size)
Returns:
{'y': 200, 'x': 125}
{'width': 87, 'height': 32}
Elements also have a property called rect which is itself a dict, and contains the element's size and location.
