39-year-old Caroline Arthur, a former model who lives in Melbourne, has legs that measure a whopping 51.5 inches from hip to heel. Incredibly, Caroline’s legs account for 69 percent of her height, and she is now seeking an official measurement to see if she can claim the world record. /CFP Photo

The current Guinness World Record for leg length is held by Russia's Svetlana Pankratova, whose legs measures at 51.9 inches. /CFP Photo

Since it’ so close to her 51.5 inches measurement, Caroline believes it’s worth “finding out exactly where they measure from and getting an official, accurate measurement done.” /CFP Photo

Because it's so close I think it is worth contacting them and finding out exactly where they measure from and getting an official, accurate measurement done. /CFP Photo
