Basketball stat sheet

How to use the stat sheet

1. Open Team and roster at the bottom and enter your players, one per line with the jersey number first, for example 23 Jordan Lee. Press Save roster. Up to 15 players fit.
2. During the game, tap the button on the player's card: +2, +3 and FT are made shots, REB is a defensive rebound, then AST, STL, BLK, TO and FOUL. The small row below holds misses and Off. reb.
3. Watch the box score fill in live, with team totals at the bottom. A wrong tap? Undo removes the last entry.
4. After the game, Export CSV for a spreadsheet or Print box score. Everything is saved in your browser, so a reload at halftime does not lose the stats.

Prefer paper? Print blank stat sheet gives a landscape page with your roster down the side and wide boxes for tally marks: 2PT, 3PT and FT made and attempted, offensive and defensive rebounds, assists, steals, blocks, turnovers, fouls and points. With no roster saved, the rows print empty.

Using the shot chart

Shot chart (off by default) opens a half court drawn to scale for high school, NCAA, NBA or FIBA. Tap the shooter's jersey, tap the spot, then Made or Missed. The sheet decides 2 or 3 from the distance to the basket, and the shot counts in PTS, FG and 3P exactly like the +2 and +3 buttons. Made shots are filled dots in the player's color, misses a small x.

The line is 19 ft 9 in from the center of the basket in high school, 22 ft 1¾ in in college, 23 ft 9 in in the NBA and 6.75 m under FIBA rules. In the corners it runs straight, so an NBA corner three is only 22 ft. A spot on the line is a two.

What each stat means

• PTS – points: 2 for each 2-point basket, 3 for each three, 1 for each free throw made.
• FG – field goals made-attempted, all 2PT and 3PT shots together (free throws are not field goals). "5-11" means 5 made from 11 shots.
• 3P and FT – three-pointers and free throws, made-attempted.
• OREB / DREB / REB – rebounds after your own team's miss (offensive) or the opponent's miss (defensive), and their total.
• AST – assist: the pass that leads directly to a made basket.
• STL – steal: a defender takes the ball away, by picking off a pass or taking it off the dribble.
• BLK – block: a defender deflects a shot attempt. The shooter still gets a missed attempt.
• TO – turnover: losing the ball to the other team without a shot, such as a bad pass, traveling or a stolen ball.
• PF – personal fouls charged to the player.

The percentage formulas

FG% = FG made ÷ FG attempted × 100

3P% = 3PT made ÷ 3PT attempted × 100

FT% = FT made ÷ FT attempted × 100

PTS = 2 × 2PT made + 3 × 3PT made + FT made

A player with no attempts has no percentage, so the sheet shows a dash rather than 0%. Percentages are rounded to one decimal place, as most box scores do.

Worked example

Jordan makes 3 two-pointers and misses 3, makes 2 threes and misses 3, and goes 3 for 4 at the line. That is:

• Field goals: 3 + 2 = 5 made from 6 + 5 = 11 attempts, so FG 5-11 and FG% = 5 ÷ 11 × 100 = 45.5%.
• Threes: 3P 2-5, 3P% = 2 ÷ 5 × 100 = 40.0%.
• Free throws: FT 3-4, FT% = 3 ÷ 4 × 100 = 75.0%.
• Points: 2 × 3 + 3 × 2 + 3 = 15.

Add 2 offensive and 4 defensive rebounds and the line reads 6 REB. If teammate Sam goes 2-2 from the floor and 0-2 at the line, the team totals are 19 points on 7-13 shooting, 7 ÷ 13 = 53.8%.

Coaches often add effective field goal percentage, which gives a three 50% more credit: (FG made + 0.5 × 3PT made) ÷ FG attempted. For Jordan that is (5 + 1) ÷ 11 = 54.5%, a better picture of a shooter who takes many threes.

Tips for keeping stats

• Use two people in a fast game: one calls the play, one taps. Rebounds and assists are the stats most often missed.
• Check against the scoreboard at each break. If your team points differ from the official score, a basket was missed or entered for the wrong player.
• Be consistent about assists and steals over a season; agree on a standard with whoever else keeps stats.

How we tested it

We wrote automated tests for the stat code and ran them with Node. They replay the worked example and check Jordan's line (15 points, FG 5-11 = 45.5%, 3P 2-5 = 40.0%, FT 3-4 = 75.0%, 6 rebounds) and the team totals (19 points, 7-13 = 53.8%). Other checks: no attempts shows a dash, 1 of 3 shows 33.3% and 2 of 3 shows 66.7%; 200 random games always give points = 2 × 2PT made + 3 × 3PT made + FT made and rebounds = offensive + defensive; undo removes only the last entry; roster lines with or without a "#" are read correctly and capped at 15; and the CSV export has the right header, player rows and totals row.

Shot chart tests, for every level: spots 5 cm inside and outside the arc (top and wing) and the corner lines (both corners) give 2 and 3; on the line is a 2; an NBA shot 22.2 ft out in the corner is a 3; and chart shots give the same box score as the +2, +3 and 3 miss buttons.
