This record belongs to different people for different formats of the game.
Assuming we’re only talking about elite-level cricket (massive personal totals are common in school cricket in India – one schoolboy, Pranav Dhanawade, made a bonkers 1,009 not out for KC Gandhi School against Arya Gurukul School in 2016), the top score ever made by a single player is the 501 hit by Brian Lara for Warwickshire against Durham in England’s County Championship in 1994.
Incredibly, Lara – the great West Indian batsman – also holds the world record individual Test score. His 400 not out came against England in Antigua in 2004.
In ODIs, Indian opener Rohit Sharma leads the way. Sharma smashed the Sri Lanka bowling attack all over Eden Gardens in 2014 on his way to 264. Remarkably, he has made three of the 10 one-day international double hundreds in history.
Sachin Tendulkar was the first to achieve the feat, against South Africa in 2010, while two women have secured their places on the illustrious list.
Amelia Kerr of New Zealand smashed 232 not out against Ireland in 2018, beating Australian Belinda Clark’s longstanding record of 229 – made against Denmark 21 years previously.
In all 50-over cricket at elite level, the top individual score is 268, by Surrey batsman Ali Brown against Gloucestershire at the Oval in 2002.
T20 cricket has yet to see an individual double century, with the current record held by Chris Gayle who made 175 not out for Royal Challengers Bangalore against Rising Pune Supergiant in the IPL in 2013.
