How Big Is a Silver Bar?

There are many ways to invest in silver bullion. The most common ways are through the purchase of silver coins and silver bars.

Check out these photos of different sized silver bars, pictured in context with everyday objects.
This should give you a better sense of the general sizes in which silver bars are available:

How Big is a 1 Troy oz Silver Bar (31.1 grams)?

The 20 gram is close enough in size and weight to 1 Troy oz that it can easily be mistaken by someone without much experience holding different bars. That’s why it’s important to always check the label to make sure you are certain you know what size bar you are dealing with.

  • Width: 25.4mm (1 inches)
  • Length: 50.8mm (2 inches)
  • Depth/Thickness: 3.175mm (.125 inches)

How Big is a 5 Troy oz Silver Bar (155.5 grams)?

The 1 Troy oz silver bar is the most common size traded around the world. Even countries that use the metric system still produce bars (and coins) in the 1 Troy oz size, since it is so popular. Here in America, we normally convert weights using pounds. 14.58 troy ounces (oz t) in silver is equal to one pound. In the silver business, if someone just says “silver bar,” they are probably referring to the 1 Troy oz size. While we’re on the subject, don’t confuse a Troy ounce (the unit of measure used for precious metals) with the avoirdupois ounce (like your local grocery store or bathroom scale might use). A Troy ounce is “heavier” than an avoirdupois ounce. There are 31.1 grams in a Troy ounce, but only 28.35 grams in a “regular” avoirdupois ounce. This bar is about the same size as a military dog-tag, but a bit thicker.

  • Width: 38.1mm (1.5 inches)
  • Length: 63.5mm (2.5 inches)
  • Depth/Thickness: 6.35mm (.25 inches)

How Big is a 10 Troy oz Silver Bar (311.035 grams)?

The 10 oz silver bar feels very solid in the palm of your hand. The price-per-ounce is definitely less than the smaller-size bars, which can make a larger bar like this more economical than buying 50 10 1oz bars.

  • Width: 50.8mm (2 inches)
  • Length: 88.9mm (3.5 inches)
  • Depth/Thickness: 6.35mm (.25 inches)

How Big is a 1 kilo Silver Bar (32.1507 Troy oz)?

The 1 kilo silver baris a popular size in the international silver trade. Though the price-per-gram is low, a bar this size limits your options if you ever want to liquidate little-by-little.

  • Width: 57.15mm (2.25 inches)
  • Length: 114.3mm (4.5 inches)
  • Depth/Thickness: 12.7mm (.5 inches)

How Big is a 100 Troy oz Silver Bar (3110.35 grams)?

A 100 Troy oz bar is an economical way to own and store silver. Due to the value, these are big and valuable enough that storage can require a bit of planning and preparation.

  • Width: 79.375mm (3.125 inches)
  • Length: 139.7mm (5.5 inches)
  • Depth/Thickness: 25.4mm (1 inches)

How Big is a 1000 oz Silver Bar (62.5 lbs)?

The largest commonly available silver bar for individual investors is the 1000 oz silver bar. A monster to handle weighing in at 62.5 pounds.

  • Width: 127mm (5 inches)
  • Length: 304.8mm (12 inches)
  • Depth/Thickness: 82.5mm (3.25 inches)
