Gold Bar Sizes and Prices

Gold bars are produced in a wide range of sizes to suit different budgets and investment goals. The most common sizes available from major dealers include 1 gram, 5 gram, 10 gram, 20 gram, 1 troy ounce (31.1g), 50 gram, 100 gram, 10 troy ounce (311g), 1 kilogram, and the institutional 400 troy ounce "Good Delivery" bar. The 1 oz, 10 oz, and 1 kg sizes are the most popular among individual investors due to their balance of low premiums and manageable cost.

The price of a gold bar depends on its weight and the current spot price of gold, plus a dealer premium. A 1 gram bar may cost around $100–$200, a 1 oz bar typically ranges from $5,000–$5,500 (at current prices), and a 1 kg bar can exceed $165,000. Larger bars generally carry lower percentage premiums over the spot price, making them more cost-efficient per ounce of gold.

Yes, it is completely legal for individuals to own a 400 oz (approximately 12.4 kg) gold bar in the United States and most countries worldwide. These bars, known as "Good Delivery" bars, conform to London Bullion Market Association (LBMA) standards and are the same bars traded between central banks and institutional investors. However, they are typically priced at over $2 million, require specialized secure storage, and may have limited resale options through standard retail dealers.

The cheapest gold bar by absolute price is typically a 1 gram bar, which can be purchased for around $100–$200 depending on the dealer. However, 1 gram bars carry the highest premiums (often 15–30% over spot price). If you are looking for the best value per ounce of gold, larger bars like 10 oz or 1 kg sizes offer the lowest premiums, typically 1–3% over spot. Our Best-Value Calculator above can help you find the optimal bar size for your specific budget.

The "best" size depends on your budget and goals. For most individual investors, the 1 oz gold bar offers the best combination of liquidity, affordability, and reasonable premiums (typically 2–4% over spot). Investors with larger budgets ($50,000+) benefit from 10 oz or 1 kg bars, which carry even lower premiums (often under 2%). If you are investing less than $5,000, consider 10g or 20g bars for a balance between premium and accessibility. Always compare premiums across dealers before purchasing.
