What Is a Standard Betting Line?
A standard betting line prices both sides of a point spread or total at -110, meaning you risk C$110 to win C$100. The two sides imply 52.4% each, totalling 104.8%, and that extra 4.8% is the sportsbook's margin. When bettors say a line is standard, they mean the juice is -110 rather than a worse price like -115 or -120.
Where -110 Comes From
Spreads and totals are designed to be coin flips. The sportsbook sets the number, say Argonauts -6.5, so that either side is close to a 50% proposition, then charges -110 on both. Risking C$110 to win C$100 on a true 50% chance guarantees the book about 4.5 cents per dollar wagered over time, no matter which side the public prefers.
The full line on a board has three parts. Take an NHL matchup: Maple Leafs -1.5 (+170) on the puck line, moneyline -150, total 6.5 with over at -105 and under at -115. The number is the handicap or total, and the figure in brackets is the price you are paid at. Reading both together is what reading a line means.
Books shade prices when action gets lopsided. If everyone piles on the over, the book might move the total from 6.5 to 7, or first adjust the juice to over -120 and under +100. A line that drifts off standard is information about where the money is going.
Standard vs Reduced Juice, in Dollars
The difference between -110 and -105 looks trivial and is not. At -110 your break-even win rate is 52.38%. At -105 it drops to 51.22%. A bettor hitting 52% of spread bets loses money at standard juice and profits at reduced juice. Over 500 bets of C$100, that gap is worth roughly C$500 to C$600.
This is why line shopping matters more than any handicapping trick. Ontario's open market means dozens of licensed books post the same games, and the same Leafs puck line might be +165 at one book and +180 at another. Taking the best available number on every bet is a free improvement of one to two percent on your return.
