Free pinewood derby heat chart generator
Type how many cars and lanes you have, or paste your racers' names, one per line. Hit Shuffle so nobody can say the order was stacked, then print it or copy it into a spreadsheet.
How to read your chart
Each row is one heat. Read across to see which cars race together and which lane each one is in. Read down any lane column and every car shows up exactly once. That's the whole point: whatever quirks your lanes have, every car deals with all of them equally.
The last column is a box to tick when a heat is done. It sounds small, but on race night it's the difference between "wait, did we run heat 14?" and just knowing.
Why this is the fair way to do it
No track is perfectly even. One lane has a joint that's slightly off, another has a guide strip that drags. By the third heat, every parent in the room knows which lane is "the fast one." If some cars get that lane more often than others, the results are partly about luck.
Giving every car one run in every lane takes the lanes out of the equation. It's the most common way to run a pinewood derby or Awana Grand Prix, and it's what most race leaders mean when they say "a fair heat chart." If you want the longer explanation, with worked examples, the heat chart guide walks through it.
Three tips before you print
- One chart per group. Run the generator once for each den, club or age group. Little kids racing against fifth graders' cars isn't fun for anyone.
- Shuffle, don't sort. Number cars in check-in order and siblings and carpools end up side by side. Shuffling also heads off the "did you put my kid against the fast cars?" conversation.
- Make the chart after check-in, not before. If a car doesn't show, a chart made the night before has a hole in it. Wait until inspection closes, then build it with the cars that are actually there.
Short on time? A heat takes 60 to 90 seconds once you count loading the cars and resetting the gate. A 20-car den on a 4-lane track is about 20 heats, so plan on 25 minutes or so.
When a printed chart stops being enough
A paper chart works well for a small race. Where it gets harder is everything around it: a car that breaks in heat 6, a family that shows up late, a close finish someone wants to argue about, and adding up every car's places at the end while forty kids wait for trophies.
That's the part Derby Dashboard handles. It builds the same every-car-every-lane chart from the cars you checked in, shows who's racing and who's on deck on the big screen, lets a judge tap in the finish order, and adds up the standings as you go. The guide to running heats covers how race night flows either way, with or without software.
