PineWood Derby Rules for Pack 12

These are the rules we use for our Cub Scout Pack 12 Pinewood Derby races. Rules differ from pack to pack, but these are fairly standard and help keep things fair and fun for everyone.

All cars will need to pass inspection before the race so please be careful to pay close attention to the rules when building your car.

Our derby is open to all scouts, siblings, parents and grandparents. Only scouts participate in the Trophies with the exception of the "Fastest Siblings Car" award. Mom's, Dad's and Grandparents compete for bragging rights only :)


    • Each boy should build his car with adult supervision. Adults should not build cars while boys watch.
    • Each car should be built new this Scouting season, from new materials. Do not recycle last year’s fast car, best wheels, etc..
    • Only one car per Scout will be allowed to register.
    • Scouts should be in Class A uniform and must be present to compete/win.

Pinewood Derby Car Dimension Rules

    • The overall length of the car shall not exceed 7 inches.
    • The overall width of the car shall not exceed 2 ¾ inches.
    • The car must have 1 ¾” clearance between the wheels.
    • The car must have 3/8” clearance underneath the body so it does not rub on the track.
