| - Ivanhoe displaced at standard load and at deep load. The ship had an overall length of , a beam of and a draught of . She was powered by Parsons geared steam turbines, driving two shafts, which developed a total of and gave a maximum speed of . Steam for the turbines was provided by three Admiralty 3-drum water-tube boilers. Ivanhoe carried a maximum of of fuel oil that gave her a range of at . The ship's complement was 145 officers and enlisted men in peacetime. The ship mounted four 45-calibre 4.7-inch Mk IX guns in single mounts, designated 'A', 'B', 'X', and 'Y' from front to rear. For anti-aircraft (AA) defence, Ivanhoe had two quadruple Mark I mounts for the 0.5 inch Vickers Mk III machine gun. She was fitted with two above-water quintuple torpedo tube mounts for torpedoes. One depth charge rail and two throwers were fitted; 30 depth charges were originally carried, but this increased to 35 shortly after the war began. She was one of the four I-class destroyers fitted with minelaying equipment in late 1938 – January 1939 at Malta. This consisted of mounts for rails on the deck on which to carry the mines and an electric winch to move the mines down the rails. A pair of sponsons were added to the stern to allow the mines to clear the propellers when dropped into the sea. 'A' and 'Y' guns and both sets of torpedo tubes were modified to allow them to be removed to compensate for the weight of the mines. The ship could carry a maximum of 72 mines. Ivanhoe was fitted with the ASDIC sound detection system to locate submarines underwater.
