How big is the biggest bar of gold?

The largest bar of gold in the world is a 250 kg (551 lb 2 oz) bar that is currently on display at the Toi Gold Museum in Izu, Shizuoka Prefecture, Japan. This massive bar measures 17.9 inches by 8.9 inches at the base and is 16.7 inches high, making it one of the most impressive gold bars ever created. Produced by Mitsubishi Materials Corporation, it has an official Guinness World record certificate for “largest gold bar” and is valued at over $15 million USD.


A hefty gold bar that is available to individual investors is the 1-kilo bar, which weighs 32.15 troy ounces and measures approximately 3 x 2 inches. This size of gold bar is much more accessible than the 400-troy ounce “good delivery bars” that are held by central banks and traded among bullion dealers.


The 400-troy-ounce (12.4-kilogram; 438.9-ounce) Good Delivery Bar is considered to be the standard gold bar held as reserves by central banks and traded among bullion dealers around the world.
