True shooting percentage is one of the quickest ways to summarize scoring efficiency because it gives proper weight to three-pointers and also accounts for trips to the free-throw line. A player can score 25 points on the same number of field-goal attempts as another player and still create those points with very different levels of efficiency. TS% helps surface that difference.
The basic idea behind TS%
Traditional field-goal percentage treats every made shot the same. A two-point jumper and a three-pointer both count as one make, even though one is worth 50% more on the scoreboard. Effective field-goal percentage fixes that problem for shots from the floor, while true shooting percentage goes one step further by incorporating free throws.
The 0.44 coefficient is an estimate designed to translate free-throw attempts into possessions. It works well for broad analysis, but it is still an approximation because not every trip to the line consumes the same type of possession.
Why analysts use it
TS% is useful when the question is simple: how efficiently did a player turn shooting opportunities into points? It allows very different scoring profiles to be compared on the same scale. A high-volume rim attacker, a movement shooter and a foul-drawing guard can all be evaluated without pretending their shot diets are identical.
What TS% does not tell you
Efficiency is not the same as offensive value. TS% does not tell you how difficult a player’s shots were, how often they created advantages for teammates, how much defensive attention they drew, or whether their scoring held up against different coverages. Usage, turnovers, passing, shot quality and lineup context still matter.
A better way to use the metric
Start with TS% as a summary, then add context. Compare the player with peers who have similar offensive roles, look at shot location and free-throw rate, and watch possessions to understand how the chances were created. When the number and the film agree, the conclusion is much stronger.
