Match maths
Boundary Percentage Calculator
How much of an innings came in fours and sixes, how often a boundary arrived, and how well the strike was rotated in between.

Beyond the calculator
Crickslab works these numbers out ball by ball while the match is on, so nobody is doing arithmetic in the scorebook.

How this was worked out
- 1Runs from boundaries(8 x 4) + (3 x 6) = 50
- 2As a share of the innings50 / 74 x 100 = 67.57
How the number is worked out
The formula
Boundary percentage = ((fours x 4) + (sixes x 6)) / runs x 100- fours, sixes
- Boundaries hit by this batter.
- runs
- The batter's total runs off the bat.
- balls per boundary
- Balls faced divided by the number of boundaries hit.
The strike rate off non boundary balls is the more revealing figure: it tells you how well the batter turned the strike over between the big shots.
A worked example: a Twenty20 innings
A batter makes 74 from 52 balls, with 8 fours and 3 sixes.
- 1Runs in boundaries(8 x 4) + (3 x 6) = 50
- 2As a share of the innings50 / 74 x 100 = 67.6 per cent
- 3Balls per boundary52 / 11 = 4.7 balls
- 4Off the other 41 balls24 runs, a strike rate of 58.5
Two thirds of the innings came in boundaries, with one every 4.7 balls. The strike rate of 58.5 off everything else says the strike was not rotated well, which is the thing to work on rather than the boundary count.
Rules and edge cases
The situations that change the answer, and the ones most calculators get wrong.
The number that matters is the one off the other balls
A high boundary percentage is often read as a compliment. It can equally mean a batter who scores only in boundaries and blocks the rest, which puts pressure on the other end. The strike rate off non boundary balls is the figure that separates the two.
Boundary runs are not the same as boundaries hit
Three sixes and eight fours is eleven boundaries and fifty runs. Sides that hit more sixes get a higher percentage from fewer scoring shots, which is why the balls per boundary figure is shown alongside.
Overthrows and all run fours do not count
A four is only a boundary if the ball reached the rope. Four runs taken by running, or four from overthrows, count towards the total but not towards the boundary count. Scorecards record these separately for exactly this reason.
Format changes what normal looks like
Around 50 to 60 per cent is ordinary in Twenty20, where the field is spread and boundaries are the main scoring source. In a one day innings 40 per cent is more typical, and in multi day cricket lower again.
Frequently asked questions
Add the runs that came in fours and sixes, divide by the batter's total runs, and multiply by 100.
For players and coaches
Where the runs actually come from
Crickslab records every ball, so boundary share, strike rotation and the wagon wheel are all there for any innings without anyone keeping a separate tally.
