Quick answer. A pound of pure gold takes up about 23.5 cubic centimeters (1.43 cubic inches). Formed into a cube, it would measure just 2.86 cm (1.13 inches) on each side, a little wider than a US quarter. That's about a quarter of the volume of a deck of playing cards, and it's worth $60,808 at today's price. Gold looks small for its weight because it's one of the densest metals there is.
| Amount of pure gold | Weight | Volume | As a cube, each edge |
|---|---|---|---|
| 1 troy ounce | 31.1 g | 1.6 cm³ | 1.17 cm (0.46 in) |
| ½ pound | 226.8 g | 11.7 cm³ | 2.27 cm (0.89 in) |
| 1 pound | 453.6 g | 23.5 cm³ | 2.86 cm (1.13 in) |
| 1 kilogram | 1,000 g | 51.8 cm³ | 3.73 cm (1.47 in) |
| 10 pounds | 4,536 g | 234.8 cm³ | 6.17 cm (2.43 in) |
| 400 oz Good Delivery bar | 12,441 g | 644 cm³ | 8.64 cm (3.40 in) |
Why a Pound of Gold Is So Small
Size is weight divided by density, and gold's density is extreme: 19.32 grams per cubic centimeter for pure gold at room temperature. That's 19.3 times the density of water. A pound of water fills a 453-milliliter bottle; a pound of gold fits in a cube smaller than a golf ball.
Put next to other metals, the difference is easy to picture. Each row below is exactly one pound:
| One pound of… | Density (g/cm³) | Volume |
|---|---|---|
| Aluminum | 2.70 | 168 cm³ |
| Silver | 10.49 | 43.2 cm³ |
| Lead | 11.34 | 40.0 cm³ |
| Gold | 19.32 | 23.5 cm³ |
| Water | 1.00 | 454 cm³ |
A pound of silver takes up nearly twice the space of a pound of gold, and a pound of lead, the metal everyone thinks of as heavy, is still 70% bigger. The practical result is that gold of great value is physically tiny. $60,808 of it would sit in your palm with room to spare.
Everyday Comparisons
Numbers like "23.5 cm³" are hard to picture, so here are some objects you can check at home.
- A US quarter. A quarter is 24.26 mm across. A pound of gold shaped as a cube would be 28.6 mm on each edge, so it's a cube just slightly wider than a quarter, in all three directions.
- A golf ball. A regulation golf ball is at least 1.68 inches (42.67 mm) across, about 40.7 cm³. A pound of gold is roughly 58% of a golf ball's volume.
- A deck of cards. A standard poker deck is about 90 cm³. A pound of gold is about a quarter of that. (You'll sometimes read that a pound of gold is "the size of a deck of cards"; it isn't. It's closer to the size of a deck cut into quarters.)
- Stacked coins. Fifteen 1 oz American Gold Eagles, just over a pound of gold content, make a stack about 4.3 cm (1.7 inches) tall and 3.3 cm wide. Fifteen Gold Buffalos stack to about 4.4 cm.
The coin stack is bigger than the cube because coins aren't pure: an Eagle is 22-karat, with copper and silver alloyed in, and the relief design and rims add air around the metal when you stack them.
Karat Gold Takes Up More Room
Everything above is for pure gold. Jewelry and most older coins are alloys, and the metals mixed in (copper, silver, zinc, nickel) are all much lighter than gold. So a pound of 14-karat jewelry takes up noticeably more space than a pound of pure gold, and a pound of 10-karat more still, even though they weigh the same. That's also why a pound of karat gold is worth less: at today's price a pound of 14k is $35,471 against $60,808 for pure. See 14k gold price per pound for every karat.
Size as a Counterfeit Check
Because gold's density is so distinctive, size and weight together are one of the oldest tests of whether something is really gold. A bar that's too big for its stated weight is almost certainly not solid gold. Dealers and some serious buyers measure a bar's dimensions or displaced water volume and compare it with the density of gold.
There's one important weakness. Tungsten has a density of about 19.25 g/cm³, within half a percent of gold's. A pound of tungsten takes up 23.56 cm³ against gold's 23.48, a difference too small to see or measure with a ruler. That's exactly why the most dangerous counterfeit gold bars are tungsten cores plated or wrapped in real gold: they pass a size-and-weight check.
That's a reason to buy from established dealers and recognized refiners rather than from strangers, and it's why dealers use ultrasonic testing, conductivity meters and XRF analyzers rather than measurement alone. For coins, size and weight still catch most fakes, because counterfeiters rarely match a government coin's exact diameter, thickness and weight all at once.
What a Pound of Gold Is Like to Hold
People who handle gold for the first time are almost always surprised by the weight. A pound of gold feels far heavier than something of its size has any right to, because your hand expects a 2.9 cm cube to weigh about as much as a sugar lump or a die. It weighs exactly as much as a one-pound bag of sugar, in a small fraction of the space.
It's also why a pound of gold is easy to store and easy to misplace. Fifteen coins in a tube fit in a shirt pocket. A home safe designed for documents will hold many pounds of gold in a single drawer, so the limit on home storage is insurance and security, not space. Our buying guide covers storage options for a pound or more.
Worked Examples
The volume of 5 pounds. 5 × 23.48 = 117.4 cm³, about half a cup.
The edge of a cube of 100 troy ounces. 100 × 31.10 g = 3,110 g ÷ 19.32 = 161 cm³, a cube 5.44 cm on each edge.
How much gold fits in one cubic inch?
16.39 cm³ × 19.32 = 316.6 g, about 0.7 pounds, worth roughly $42,443 today.

FAQ
How big is a pound of gold?
About 23.5 cubic centimeters, a cube 2.86 cm (1.13 inches) on each side.
Is a pound of gold the size of a deck of cards?
No. It's about a quarter of a deck's volume. The "deck of cards" comparison is common but wrong.
How big is a pound of gold compared with a pound of silver?
A pound of silver is about 43 cubic centimeters, nearly twice the size of a pound of gold.
Why is gold so heavy for its size?
Gold atoms are heavy and packed tightly, giving it a density of 19.32 g/cm³, among the highest of any metal.
Can you tell real gold by its size?
Size and weight catch many fakes, but not tungsten, which is almost exactly as dense as gold. Buy from established dealers, who test with instruments.
