Records
These were the standing world and Olympic records (in points) prior to the 1988 Summer Olympics.

(*) Original score according to the 1962/1977 tables.

(**) Score according to the 1985 tables.

Thompson's mark was not a world record in 1984, but when the 1985 tables came into use, his mark became the record. They were both given credit for the world record.

Results
{{legend|#F2F5A9|The highest mark recorded in each event is highlighted in yellow. These marks were split between six competitors with the gold medallist claiming the high jump mark.|border=solid 1px #AAAAAA}}

Curiously, neither the silver nor bronze medallists claimed any of these marks yet the competitor who placed 17th claimed three of them.
