Grade is situated on the Lizard, in the Meneage district, and in the Deanery and Hundred of Kerrier. The parish was divided into four detached portions. The first portion, upon which the Church stands, is bounded on the West and North by Ruan Minor, on the East by the ocean, and on the South by Landwednack. The second portion was bounded on the North and East by St Keverne and the ocean, on the South by Ruan Minor, and on the West by Ruan Major. The third portion is surrounded by the parish of Ruan Major. The fourth portion was bounded on the North, East and South by the parish of Ruan Major, and on the West by Mullion. Grade is situated on the most southerly peninsula in Cornwall. Because of small populations, in 1934 Grade united with Ruan Major and Ruan Minor to form a single parish of Grade - Ruan.
