What Are Alternate Lines? Alt Spreads and Totals Explained
The main line says your team is -3. You think they win by double digits. Instead of settling for -110, you can move the spread to -7.5 and get paid around +210, or to -10.5 for something like +300. Those menus of extra spreads and totals are called alternate lines, and nearly every major sportsbook offers them.
How alternate lines work
Every game has a main line, usually priced close to -110 on both sides. Alternate spreads and alternate totals keep the same game but change the number. Make it easier to win and the price gets shorter. Make it harder and the payout grows.
How alternate spreads are priced
Here is an illustrative ladder for a game where the main line is -3 at -110. Each row is a separate bet with its own price.
| Favorite spread | Odds | $100 profits | Implied chance |
|---|---|---|---|
| -1.5 | -160 | $62.50 | 61.5% |
| -2.5 | -140 | $71.43 | 58.3% |
| -3 (main line) | -110 | $90.91 | 52.4% |
| -3.5 | +100 | $100 | 50.0% |
| -6.5 | +170 | $170 | 37.0% |
| -7 | +185 | $185 | 35.1% |
| -7.5 | +210 | $210 | 32.3% |
| -10.5 | +300 | $300 | 25.0% |
Notice the gaps. Moving from -2.5 to -3.5 drops the implied chance by more than 8 points, a bigger change than moving from -6.5 to -7.5. That is because so many NFL games end with a 3-point margin. Our guide to NFL key numbers explains why 3 and 7 carry so much weight, and buying points covers the half-point version of the same idea.
Alternate totals
Alternate totals work the same way. If the main total is 45.5 at -110, you might see over 41.5 at around -175 or over 51.5 at around +200 (illustrative). They are popular when you expect a shootout or a defensive slog and want to be paid for being more confident than the market. Our over/under guide covers the main-line version.
When alternate lines make sense
- You have a strong view on the margin. If you think a favorite wins big, an alternate spread pays you for that view instead of just for the cover.
- Crossing a key number cheaply. Sometimes moving a spread through 3 or 7 costs less at one book than another. Shop it.
- Building parlays. Many bettors use alternate lines in parlays and same game parlays to raise or lower the risk of each leg.
- Laddering. Some bettors split a stake across several alternate spreads, for example -3, -7 and -10.5, so a blowout pays big while a narrow win still returns something.
What to watch out for
- Heavy juice on safe-looking lines. Taking an underdog from +3 to +13.5 might cost -600. You risk $600 to win $100, and one bad game wipes out six wins.
- Extra margin. Alternate lines often carry more built-in vig than the main line, so the price matters even more.
- Teasers may be cheaper. If you want to move two or more lines in your favor, a teaser can sometimes cost less than parlaying alternate lines. Compare both.
Worked example
You like a 3-point favorite and think it wins comfortably. Here are three ways to bet $100:
| Bet | Odds | Win by 2 | Win by 5 | Win by 10 |
|---|---|---|---|---|
| Main line -3 | -110 | −$100 | +$90.91 | +$90.91 |
| Alt -1.5 | -160 | +$62.50 | +$62.50 | +$62.50 |
| Alt -7.5 | +210 | −$100 | −$100 | +$210 |
How to find alternate lines at your sportsbook
One more habit worth building: after the game, look at which line on the ladder would have been the best bet. Over a season, that record tells you whether your margin reads are sharp enough to justify alternate spreads, or whether you are better off on the main line.
