# What Is a Leg in Sports Betting?

When you are researching sports betting odds, you will often come across the terms “leg” or “lei” used to describe the unit of measurement for odds. You are probably wondering: What is a leg? And, more importantly, what is the difference between the American and British/Commonwealth styles of spelling? Let’s delve into these questions and more as we answer the age-old question: What are the odds of winning a game?

## Define Leg

If you are new to the world of sports betting, you may not be exactly sure what a leg is. The concept of a leg can be difficult to wrap your head around since there is no standardized measure for it. Different bookmakers will use different names for the leg unit: American (“dime”) vs. British/Commonwealth (“penny”) vs. Japanese (“sen”).

The first thing you should know about betting on sports is that most sportsbooks calculate their odds using a formula called the “unweighted betting ratio.” This is different from the “traditional” way of quoting odds, where you would typically find “7/2” or “2.5/1” in relation to a favorite winning vs. odds of an underdog winning. The unweighted betting ratio gives more emphasis to the betting activity that took place before the bet was placed, while the traditional odds are more representative of the current state of affairs.

## Leg vs. Penny

A penny is a coin worth one hundredth of a pound. A leg is the measurement used in the unweighted betting ratio to account for the fact that more bets are placed on favorites than on underdogs. A 1-to-4 leg will indicate that there were four times more bets on the favorite than there were on the underdog in an NCAA football game between LSU and Alabama. Using a 1-to-4 leg to calculate the odds in an NBA game would result in 4/1 odds for the home team. It would be the same if you were backing the Green Bay Packers in an NFL football game versus the Chicago Bears or vice versa.

Nowadays, many sportsbooks adopt the American practice of using legs to measure odds instead of the British/Commonwealth method. This is largely due to the fact that more people are identifying themselves as American than British. For example, the bet365 website uses the American format, along with the dollar (“dime”) and cent (“cents”) as their base units. If you are a user of the betting exchange (Betfair), you will notice that the pound sterling is not displayed as a unit of measurement, but rather as a symbol denoting how many pounds are in a dollar. The site uses the British/Commonwealth practice of “p” instead of “f” to represent the dollar.

## Odds Are More Important Than Odds

When you are entering into a bet with a bookmaker, what you are actually doing is placing a wager. Wagers can be of any size, but to keep things simple, we will use the \$10 bet for this example. If you are betting \$10 on the favorite, you are essentially placing a wager of \$10 on the outcome of the game.

When you compare this to a \$10 wager on an underdog, you are actually placing a \$20 wager. A standard unit of measurement for these odds will be “20/1” or “1/20.” The fact that you are betting \$20 on the underdog means you are effectively taking the \$10 wager you made and multiplying it by 20. What this means in practical terms is that you would need to win \$20 to break even on your \$10 wager. In order to win \$20 on the favorite, you would need to win the game by at least 20 points (+20).

## What Is The American Style of Speling?

The American practice of spelling is used mainly in the United States, where the official language is English. Spelling competitions have been held since the 1800s, and in recent times, the practice has become quite popular. One of the first major league sportsbooks to offer American-style football games was BetAmerica (formerly Interplay Sports), which adopted the format as a way to attract potential customers who were used to placing online wagers on the NFL and NBA.

Many different systems of spelling have developed over the years, and it is not uncommon for even the most hardcore Yanks (Yankees) to spell “baseball” different ways. Since the Yankees play in New York City, “Yankees” is typically how they spell the word: (Y)ank(E)es or (Y)ane(K)es. However, down in Tampa Bay, Tamp(A)y is the way they spell the baseball team.

## How Is A Coin Worth In A Betting Exchange?

A betting exchange is an online marketplace where people can exchange currency for digital assets, such as stocks, bonds, or other cryptocurrencies. The first major online betting exchange was Betfair, which was founded in the United Kingdom in 1994 and is now headquartered in Luxembourg. Betfair offers a currency-agnostic approach to betting, allowing users to place wagers in Pound Sterling (£), Euro (€), or Dollar (℠), among other currencies. It also doesn’t require users to register, as most sportsbooks do, in order to place bets.

## The Final Word

As you work your way through the maze that is the World Wide Web and come across different online sportsbooks, you will notice that each one has its quirks. Some prefer to use pennies for their odds, while others may use dimes. One thing that all of them have in common is that they are all likely to accept Dollars as a form of payment, as most Americans know how to spell it correctly. Finally, make sure you establish a legitimate betting account with a trustworthy sportsbook before you start placing bets, as many sportsbooks have agreed to pay out winnings from unlawful activities. This way, you can rest assured you are playing fair and keeping all your money.
