When U.S. Banknote Sizing Standards Were Introduced

100 Dollars Bill

The dimensions of a 100-dollar bill in inches have not always been standardized. Prior to 1929, U.S. banknotes were issued in a variety of sizes, which often caused confusion and made it easier for counterfeiters to create convincing replicas.

Pre-1929 Currency

Before the introduction of standardized sizing, the dimensions of a 100-dollar bill varied depending on the series and issuing bank. For example, the dimensions of a 100-dollar bill from the 1890 series were approximately 7.375 inches by 3.125 inches, while the dimensions of a 100-dollar bill from the 1907 series were approximately 7.375 inches by 3.125 inches.

These variations made it difficult for individuals to quickly verify the authenticity of a banknote.

The Move to Standardized Sizes

In an effort to combat counterfeiting and streamline the production process, the U.S. government introduced standardized sizing for banknotes in 1929. This meant that all newly printed banknotes, including the 100-dollar bill, would have the same dimensions.

The dimensions of a 100-dollar bill were set at approximately 6.14 inches by 2.61 inches, which remains the standard size to this day.

The introduction of standardized sizing made it easier for individuals to quickly identify counterfeit banknotes. It also allowed for more efficient printing and storage of banknotes, as they could now be produced and handled in a uniform manner.

Series 1996 Redesign

Series 1996 100 Dollars Bill

In 1996, the U.S. government redesigned the 100-dollar bill to incorporate enhanced security features and a more modern design. While the dimensions of a 100-dollar bill remained the same, the overall appearance of the banknote was updated.

The redesign included the addition of a larger portrait of Benjamin Franklin, as well as a watermark, security thread, and color-shifting ink. These features were implemented to make it even more difficult for counterfeiters to replicate the banknote.

Design and Security Features

When it comes to the design and security features of the 100-dollar bill, there are several elements that make it unique and difficult to counterfeit. These features not only add to the visual appeal of the bill but also help in ensuring its authenticity.

Let’s take a closer look at some of these design and security features:

Portrait and Imagery

The 100-dollar bill features a portrait of Benjamin Franklin, one of the Founding Fathers of the United States. The portrait is located on the obverse side of the bill and is surrounded by intricate filigree patterns.

The detailed engraving of Franklin’s face and the fine lines in the background make it difficult for counterfeiters to reproduce.


Watermarks are an important security feature found on the 100-dollar bill. When you hold the bill up to the light, you will see a faint image of Benjamin Franklin on the right side of the bill. This watermark is embedded into the paper and can be seen from both sides.

It serves as an additional layer of protection against counterfeiting.

Color-Shifting Ink

Another notable security feature of the 100-dollar bill is the use of color-shifting ink. The number “100” on the lower right corner of the bill changes color from copper to green when tilted. This effect is achieved through a special ink that contains microscopic lenses, creating a dynamic and eye-catching visual effect.

This feature is difficult to replicate and helps in distinguishing genuine bills from counterfeit ones.

Security Threads

A thin, embedded security thread is incorporated into the 100-dollar bill. When held up to the light, the thread appears as a continuous line running vertically through the bill. The thread is woven into the paper and is visible on both sides.

It is also microprinted with the letters “USA” and the denomination “100”. This feature adds an additional layer of security and makes it harder for counterfeiters to replicate.
