About BasketballNinja
The numbers you’re left with after the game
You play a run, or you coach one, and afterward you’re holding a handful of numbers that don’t mean much on their own: minutes played, a stat line, maybe a stopwatch time on how high you jumped. Was that a hard enough session to matter for conditioning? Is a 55% shooting night actually good once you account for threes and free throws? How does a team’s pace compare to the possession count you scribbled on a whiteboard? None of that is complicated math, but doing it by hand mid-practice, or hunting across five different forum threads with five different formulas, gets old fast.
Court dimensions run into the same problem. NBA, FIBA, NCAA, and high-school rules disagree on the three-point line, the paint, and the free-throw distance — worth knowing before you mark out a driveway hoop or argue a call. Shoe sizing has the same mess across US, UK, EU, and centimetre charts, especially when you’re ordering a brand you haven’t worn before.
What BasketballNinja does about it
BasketballNinja is a set of free calculators built to answer those specific questions without the runaround. The Basketball Calories Burned Calculator turns your weight, minutes, and intensity into a MET-based total and a per-minute rate. The Vertical Jump & Reach Calculator works from either standing reach and max touch, or hang time, and adds an estimated peak power figure using the Sayers formula. The Basketball Pace Calculator converts a box score into possessions and pace per 48 minutes, for one team or both.
For shooting and performance, the PER (Player Efficiency Rating) Calculator runs Hollinger’s Game Score plus a PER proxy from a full box-score line, and the Basketball Shot Percentage Calculator handles FG%, 3P%, FT%, eFG%, and TS% with divide-by-zero-safe math. The Basketball Stats Tracker rolls a game or a season into per-game averages and totals, and the NBA Draft Analyzerweighs a prospect’s production, age, and physical profile to gauge draft stock.
The rest cover the practical side of the game: the Basketball Court Dimensions Calculator for NBA, FIBA, NCAA, and high-school specs in feet or metres; the Basketball Shoe Size Converter across US, UK, EU, and cm; the Basketball Training Planner for a week balanced across shooting, ball-handling, conditioning, and strength; the Tournament Bracket Generator for seeded single-elimination brackets with byes handled automatically; and the Fantasy Basketball Analyzer for scoring players by category or points-league value. Past the calculators, the blog and learn section cover the same topics in more depth, and the Museum of Basketball & the Hardwoodis a separate, browsable history of the game — its origins and rules, courts and gear, and leagues and competitions — built from Wikipedia and Wikimedia Commons entries.
What this is, plainly
BasketballNinja is an independent, advertising-supported site. It is not affiliated with the NBA, FIBA, the NCAA, or any shoe or equipment brand referenced in its tools and reference pages — the dimensions and rules cited are public standards, used here for calculation and comparison, not endorsement. Every result is an estimate built from a stated formula and the inputs you provide; MET-based calorie counts, Sayers-formula power outputs, PER proxies, and pace figures are all approximations, and real conditioning, shooting, and draft outcomes depend on far more than any calculator can capture. None of this is professional coaching, medical, athletic-training, or fitness advice — warm up, listen to your body, and check with a qualified coach, certified trainer, or physician before starting a new training program.
