Question: what is the difference between kindle fire and kindle fire hd?
Answer: The Kindle Fire and Kindle Fire HD both have 7-inch screens. The Kindle Fire HD 8.9" and 8.9" 4G, as the name suggests, have 8.9 inch screens. The 8.9" models are the thinnest in the range, with the original Fire the thickest, though the difference is very slight.
