Gold Bar Sizes Explained
NGB Hong Kong Desk·Published ·Updated
Gold bars are produced in a wide range of weights. The right size depends on your budget, how you plan to sell, and how you intend to store the metal.
Small bars (1 g to 20 g)
Small bars are an accessible entry point and are easy to gift or sell individually. Manufacturing cost is spread over very little metal, so the premium per gram is the highest of any format.
Mid-size bars (1 oz to 100 g)
One ounce and 100 g bars are the most widely traded sizes. They balance a moderate premium with straightforward resale and are usually the default choice for private investors.
Large bars (250 g to 1 kg)
Larger bars carry the lowest premium per gram and suit buyers deploying a larger amount at once. The trade-off is divisibility: you sell the whole bar or none of it.
Matching size to purpose
If you may need to release value gradually, several mid-size units are more practical than one large bar. If cost per gram is the priority and the holding will stay intact, larger bars are more efficient.
