Rankmore was born in Cardiff and began his league career at Cardiff City after joining the club from local side Cardiff Corinthians in 1957. He was unable to break into the first team, and his early time at Ninian Park was spent mostly in the reserve side. At the end of the 1959–60 season he was placed on the transfer list. However, when Danny Malloy left the club in 1961, Rankmore found himself promoted to the first-team, making 37 league appearances during his first full season but was unable to prevent the club slipping out of Division One. After one more season as a first-team regular, Rankmore found himself out of favour again following the arrival of John Charles from Roma and was sold to Division Three side Peterborough United for a fee of £10,000.
He went on to appear over 200 times for Peterborough and was awarded his first, and only, cap for Wales when he played against Chile during a tour of South America in 1966. In 1968, he was sold to local rivals Northampton Town for £12,000, becoming the third Peterborough player to move to Northampton in the space of five months after Johnny Byrne and Jack Fairbrother, where he made over 100 appearance before injury forced him into retirement in 1971.
Rankmore's son, Frank jr, played amateur football and in 2005 scored his 500th career competitive goal while playing for local side Bridgend Street in the South Wales Senior League.
