To compare player prop odds, line up the same player and stat at every sportsbook, compare the line first and the price second, and convert both to one break-even win chance; Betwatch game pages list every book's over and under for each prop.

Worked example: one points prop at five books
One player's points prop is posted at five sportsbooks, and the lines are not the same. Over 25.5 at -135 and Over 27.5 at +100 cannot be compared by price alone, because the first needs fewer points to win.
To put every line on 26.5, assume the player lands on any one score near their average about 5% of the time, so one point of line is worth 5 points of win chance. Add 5 to the break-even chance of an Over for each point the line is above 26.5 and subtract 5 for each point below. Do the reverse for an Under. The figure in each cell is the win chance you need once the line is 26.5, and lower is better.
| Book | Line | Over: price (needs) | Under: price (needs) |
|---|---|---|---|
| Book A | 26.5 | -115 (53.5%) | -105 (51.2%) |
| Book B | 26.5 | -105 (51.2%) | -120 (54.5%) |
| Book C | 27.5 | +100 (55.0%) | -120 (49.5%) |
| Book D | 25.5 | -135 (52.4%) | +105 (53.8%) |
| Book E | 26.5 | -110 (52.4%) | -110 (52.4%) |
The best Over is Book B at 26.5 and -105, which needs 51.2%. The best Under is Book C: -120 looks like the worst price on the board, but at 27.5 the Under has a full point of extra room, and after adjusting it needs only 49.5%.
Book D shows the same thing from the other side. Over 25.5 at -135 needs 57.4% as posted, but 52.4% once it is put on 26.5, which ties the plain -110 at Book E and beats the -115 at Book A.
A pick'em app posts one line with a payout set by the entry, not a price for each pick. You cannot compare its price, only its line: if it offers 25.5 on the Over, that is a better number than any 26.5 above.
How to compare player prop odds, step by step
1. Open the game on its Betwatch odds page and find the player and stat. The props list every book's over and under, and the Live Board has every market a book posts, each with its line chart.
2. Write down each book's line and price for the side you want. Compare the line first: a lower number is better for an Over and a higher one is better for an Under.
3. Convert each price to its break-even win chance with the odds converter, then put them on one line. A point of line is worth about 5 points of win chance on a scoring prop. It is worth much more on a low-count stat such as strikeouts or touchdowns, and less on yardage.
4. Treat pick'em app lines separately. The payout is set by the entry, so only the line matters: take the app whose number is best for your side.
5. Check the price at the open, 24 hours ago and now. A book that has not moved with the rest holds an old number, which is often the best one, but it will not last.
6. Open the +EV board to see which prop prices beat the fair line, then place the bet at the best book you have an account with. In account settings you can show only your own sportsbooks and your state.

How to compare player prop odds across sportsbooks: line first, then price: questions
How do I compare one NBA player's points prop at every sportsbook?
Open the game on a Betwatch NBA game page, find the player and read each book's line and over/under side by side, with no account. Match the line first, then compare the price on it; Betwatch covers 42 odds sources (27 sportsbooks, 9 prediction markets and exchanges and 6 pick'em apps).
How do I do an NFL player prop odds comparison?
Open the NFL game page, find the player and stat, and compare the line at each book before the price. For an alternate line, such as a higher passing yards number, compare the exact same number at each book, because an alt line has its own price.
Which sportsbook pays the most on anytime touchdown scorer?
It changes by player and by day, so check each time. Anytime touchdown is a yes or no market with no line, so the book with the highest payout for the same player is the best price. The game page lists the prop at each book.
What is the best site to compare pitcher strikeout props across sportsbooks?
Any site that lists every book's line and price for the pitcher on one page. Betwatch MLB game pages do. Compare the line first: one strikeout moves the win chance far more than one point moves it on a points prop.
What is the fastest way on my phone to check which book has the best price on a player prop?
Open the game page in your phone browser, find the player and read the line and price at each book. Take the best line first, then the best price on it, and place the bet in that book's app.
How do I compare Over 25.5 at -135 with Over 27.5 at +100?
Convert each price to a break-even win chance, 57.4% and 50.0%, then adjust for the lines. With a point of line worth about 5 points of win chance on a points prop, the first needs 52.4% and the second 55.0%, so the 25.5 Over is the better bet.
