Effective Field Goal Percentage attempts to give a better indication of a NBA players overall shooting by taking into consideration three points made into the field goal calculation instead of having field goals and three point percentages separated.
It's calculated as: (Field Goals Made + 0.5 x Three Points Made)/(Field Goal Attempts)
Bubble size represents the effective field goal percentage of the player relative to the other players on the chart where the bigger the bubble the higher the eFG%. This chart only includes qualifying field goal and three point shooters. (You can use your cursor to zoom in on any portion of the chart).

The idea behind this statistic is that three points are worth 50% more than field goals (three points vs. two points), which is then reflected in the effective field goal percentage calculation by adding 50% of three pointers on top of field goals made. Players with high effective field goal percent are those considered to be highly effective and productive shooters.
